January 2018 - Blog: Pressure measurement before and after the particulate filter
Sensors in the exhaust system
As we start 2018, I should like to make another contribution to the discussion of sensors in the exhaust system.
Today`s topic: Pressure measurement before and after the particulate filter.
As stated in my last post on this page, the exhaust after treatment for combustion engines is largely determined by thermodynamic processes. Temperature and pressure conditions play a major role. The monitoring of various pressures in the exhaust pipe, among other locations, can give information about the load condition* of the particulate filter.
EURO 6 legislation recommends a particulate filter
Following the introduction of the latest emission standard "EURO 6", all manufacturers of diesel engines are required to install particulate filters in their exhaust systems. With modern diesel particulate filters (DPF), up to 99% of these fine dust particles can be eliminated from the diesel exhaust. (Ref: see footnote.) The filter principle is based on catching and collecting the particles; so clearly, such a filter will eventually reach its capacity limit. The filter is then filled with carbon particles and must be regenerated by cleaning.
The cleaning of the filter is carried out by oxidizing (burning off) the collected soot particles. There are various procedures for this regeneration. In stationary engines, these range from replacing loaded filter cartridges, to passive, more or less continuous soot combustion.
Active systems are most common in mobile applications
Most common for mobile applications, however, are active systems. Here, the regeneration process is actively initiated in various ways. Either the internal combustion engine increases the exhaust gas temperature to over 600°C, or by deliberately adding additives to the fuel, the ignition temperature of the soot coating is reduced to below 450°C. (See also my last note on temperature monitoring.)
Pressure in the exhaust pipe (relative to the environment pressure) is the trigger for the regeneration signal of the sensor
In both the cases described, regeneration is actively initiated. The trigger comes from (of course) a sensor that registers how strong the filter load actually is. An indicator of this loading is the back pressure built up in front of the particulate filter in the exhaust pipe. The higher the load condition in the filter, the greater the back pressure. A simple pressure sensor detects the dynamic pressure relative to the environment as long as there are comparable pressure conditions in the exhaust pipe after the particle filter (as with EURO 5). If a certain dynamic pressure value is reached, and the sensor has transmitted the information to the control unit, the active regeneration is started.
This kind of sensor must fulfill special requirements. The mounting position must be very close to the exhaust pipe – especially in trucks – as the sensor is not protected from the environment. This requires high robustness. At the same time, the internal pressure of the system is very low – which means that a very sensitive internal measurement is required – yet the media inside this system is one of the most aggressive we can find in automotive applications.
Specific pressure sensor for sophisticated demands in the exhaust pipe
Our Type 96724 sensor has been designed specifically for this application. A very sensitive semiconductor pressure measuring cell (MEMS - micro electro mechanical system) converts the pressure signal into an electrical voltage. This very low measurement signal is amplified in a specially developed amplifier unit (ASIC) in the sensor to a usable level, and at the same time conditioned against environmental influences.
The AB special design takes account of these requirements. Extensive optimization at the connection and joining mechanism, and close cooperation with users have enabled development of a sturdy sensor that is externally very robust, yet extremely sensitive internally.
The next level: Diesel EURO 6 engines get another catalyst
Differential Pressure Sensors for EURO6 enable systems with much higher accuracy
What has most recently discredited the diesel engine is the emission of NO and NO2, the nitrogen oxides. To effectively reduce emission of these nitrogen oxides, an additional catalytic converter is being installed in EURO 6 vehicles after the particle filter. I shall discuss this topic in a later post.
I should like to wish you a very successful start to 2018!
*The soot generated during fuel combustion in the engine is perceived as particulate matter, and are found especially in diesel engines. Particulate Matter consists of microscopically small, suspended dust grains with a particle size of at most 10 micrometers (= 10 thousandths of a millimeter). The particles are so small that they can be deposited in the lungs during inhalation, and even pass through the bloodstream into the entire human body, including the brain.

September 2017 - AB Elektronik celebrates its 50th anniversary
Employee Party and Family Day
In 1967, AB Elektronik GmbH settled in Werne, Germany, and marked its 50th anniversary with a celebration on the 16th of September. Over the last 50 years, AB has grown and established its position as the automotive partner of choice for engineering and manufacturing of position- and speed-sensors as well as accelerator pedals. At the start of this year, the company centralized all functions on approximately 22,000 sqm in the “Feldmark” area, which then became the new head office address.
This was the location of a Family Day for all 450 employees and their relatives, and attracted a good turnout on the Saturday. The factory tours were the most popular, but the trainee stand - where children got the chance to test their talent for working with sensitive electronic parts - was really busy too. In the hospitality area, the local management team offered homemade cakes, the Work Council team was very busy at the barbeque.
All functions offered some hands-on activity for people of all ages, including a big glass full of sensors, giving everyone the chance to guess the quantity. The winning prizes all had some local reference. The money raised on food, drinks and games, as well as tickets for the evening party, will be donated to a local children’s hospice.

March 2017 - Blog: Measuring automotive exhaust gas temperature
An important part of reducing the emissions of diesel combustion engines depends on knowing the temperature of the exhaust gases - let’s take a closer look at this topic:
Starting in the early 1990s, legislators around the world began to limit the amount of pollutants emitted by motor vehicles to protect the environment. While CO2 and other emissions from petrol-engines is a concern, a more significant focus has clearly been on the diesel engine.
The result - despite all the negative headlines - is, that today's diesel vehicles are significantly cleaner than 10 or 15 years ago. There are a lot of improvements but importantly amongst these are temperature sensors, measuring directly in the exhaust pipe. This is a very demanding environment and, since the introduction of the EURO 5 emission standard in 2008 that demands diesel particulate filters, TT Electronics has been actively involved in meeting this requirement.
Diesel particulate filters need temperature sensing for the regeneration process
To be effective, diesel particulate filters must be regularly regenerated during operation. Regeneration is an internal burning process, which starts at about 500 °C, and takes place without any involvement from the driver. Due to exothermicity, the release of heat during a chemical reaction, temperatures in the range of 700 to 800 °C can be achieved, which allow accumulated soot to be burnt off. In addition to pressure monitoring, which will be discussed in a later blog, temperature detection plays an important role in this process.
TT Electronics’ engineering involvement in such applications began in 2005. At that time, TT Electronics was able to purchase a license for a very robust temperature sensor setup. Subsequently based on the company’s long term experience with temperature sensors and with significant further engineering investment, TT Electronics has refined its exhaust sensor design and made it ready for high volume production.
Robust design is key for the harsh environment in the exhaust pipe of diesel engines
The outcome is a very robust temperature sensor, based on a passive resistance measuring element that responds with different resistance values at different temperatures. Platinum is used as the resistance material as this element is characterised by a nominal resistance of 200 Ohm at 0 °C (PT-200).
The most important advantage of this high-temperature sensor is its robust design. The measuring element is embedded in a monolithically closed tube made of a special stainless steel using a particular ceramic powder mixture. The bubble-free filling of the sensor tip ensures that motor vibrations do not pose a threat to the sensor's service life. In addition, the sensor can be bent from 0 to 120°. Specially developed seals guarantee a long service life even under the harshest environmental conditions in and around the exhaust pipe.
The next level of high temperature design is up to 1200 °C
The experience gained in the last few years has enabled TT Electronics to develop a new generation of high-temperature sensors. The aim of this development was to make a sensor technology suitable for use in vehicles that require temperature measurement up to 1200 °C, which is the case in petrol engines.
Robust sensor design
TT Electronics’ sensors incorporate N-type thermocouples to send continuous measurement signals to the vehicle’s control electronics. Thermocouples use the physical effect of thermoelectricity. A pair of metallic conductors of different materials are joined at one end. Due to the temperature gradient between the measuring point (hot side) and the plug side (cold side) an electric voltage is generated (see Wikipedia). This electrical voltage is proportional to the temperature change on the hot side and can thus be processed as a sensor signal. An electronic unit, which is integrated into the plug housing, provides the necessary signal processing.
Thermocouples have been used for many years in industrial electronics for temperature measurement. TT Electronics’ sensor has been specially adapted to the requirements of automotive applications and only use welded or soldered connections to avoid signal interruption. Protective housings at the sensor tip are made exclusively from high-temperature-resistant stainless steel, using deep-draw technology. The sensors can be attached to the exhaust pipe with a union nut or hollow screw of various dimensions. Cable shields are used to allow high temperature resistance measurements in the vicinity of exhaust pipes.
Various electronic interfaces are available
The electrical signal, as already mentioned, is processed electronically. Users can choose between different digital interfaces. To date, TT Electronics has implemented PWM, SENT and CAN (according to SAE J1939). Like the entire sensor, the electronics unit offers protection class IP6K9K (with its mating connector).
This sensor is suitable for temperature measurements in the range -40 to 1200 °C. With these characteristics, the sensor can be used at any point in the exhaust pipe of petrol engines. Manufacturers of turbo-charged vehicle engines can also use this sensor in the exhaust manifold (before the turbocharger) to warn against excessive temperatures, which can be dangerous for the turbocharger.
Double high temperature sensors will be required for next generation of petrol engines
With the introduction of the latest emission standard (EURO 6c), direct-injection petrol engines must also be equipped with particulate filters for the first time. These use slightly different regeneration processes that, while similar to the particulate filters in diesel engines, need to operate at higher temperatures and require temperature measurements at two points.
Precisely for this application, TT Electronics has developed a thermocouple sensor as a double module that combine two sensors with one electronics unit. Apart from cost benefits, this allows the sensors to be matched with tolerances of +/- 1 °C.

January 2017 - Sensors are critical to enabling greener vehicle emissions
Blog: Sensors are critical to enabling greener vehicle emissions
Frank Rothe, Product Application Manager Sensors, considers the importance of sensors in the drive to greener vehicle emissions
Mobility is essential to modern life, and is a key driver for economic growth. At the same time, the world's ever-increasing traffic volumes are a major source of pollution, which poses a fundamental threat to our future.
The solution lies in emission-free transport, an aim that leading car manufacturers and developers around the globe are working towards intensively. Until that goal can be fully achieved, new electronic systems and technologies will be instrumental in reducing emissions from combustion engines.
AB Elektronik is a recognised expert in this specialist field, where the impact that exhaust fumes, extremely high temperatures and other aggressive factors can have on surrounding components represents a significant challenge.
An example of these increasing demands can be found in the latest generation of high-power vehicles, where the combustion process generates ultra-high temperatures to keep emissions down. These temperatures can harm the engines’ expensive turbocharger systems, meaning that precise monitoring is required to ensure temperatures remain within acceptable bounds, and to limit the engine power, should the acceptable range be exceeded. Our state-of-the-art temperature sensors can monitor this. They transfer thermal data as electrical information which can be handled by engine control units (ECU). For the driver of the car, the impact is barely noticeable.
AB Elektroniks’ sensors excel in their ability to withstand a variety of corrosive gases and aggressive liquids, thanks to their extremely robust housing. This level of protection has traditionally come at the expense of inferior temperature measurement: enclosing the cells typically makes them slow to detect changes in temperature, when what we need for turbocharger applications is real-time information. This is where our long experience and sophisticated modular mechanics concepts come in. Combined with endlessly tried-and-tested technologies such as thermal resistive like PT-200 and others, our sensors are highly responsive and extremely resistant to harmful external factors. The variety of available technologies and our ability to design customised solutions have already proved a competitive advantage in many cases.
Further limitations on specific pollutants (soot particles, nitrous oxides, CO and CO2) have been introduced at regular intervals for on-road and off-road vehicles. Europe and the USA have played a pioneering role, and their regulations generally provide a model for other countries around the world.
The currently applicable emissions standards are EURO 6, EPA 13 (both on-road) and Tier4final (off-road). The limits defined by these standards are forcing vehicle and engine manufacturers to introduce sophisticated exhaust after-treatment systems, as well as modifying their engines. The most important adaptations are diesel oxidation catalysts (re-oxidation of unburned hydrocarbons), diesel particulate filters (retention of rust particles) and selective catalytic reduction (conversion of harmful nitrous oxides in nitrogen and water).
While this change has so far mostly affected diesel engines, some petrol engines – particularly those with direct fuel injection – will have most likely to be fitted with gasoline particulate filters from September 2018 at the latest, when the next stage of the emissions standard (EURO 6c) is due to come into force.
To implement these measures effectively, we will need extreme systems that are able to support control algorithms, so that initial process and end values can be measured and transmitted in a suitable form to the vehicles’ electronic control units (ECUs). Sensors for key indicators measure the relevant physical properties, converting them into electrical signals and then relaying them to the ECU.
For these specific requirements, AB Elektronik has a broad portfolio of temperature, pressure and fluid quality sensors, which we will expand upon in the future.

TT Electronics’ Sensing and Control division has expanded its series of sensors for electronic power steering (EPS) applications. The new Magnetorque® Plus combines TT Electronics’ proven non-contacting torque sensor with a multi-turn position sensor in a single compact package. The integrated and fully calibrated design is significant in providing engineers with an integrated solution for measuring torque and steering wheel angle.
TT Electronics’ new Magnetorque® Plus is designed to support the increasing demand for EPS systems across several sectors in the transportation market. Studies have shown that EPS systems contribute to a 3% to 4% reduction in fuel consumption, driving their use in passenger cars, off road, utility and recreational vehicles. Designed with a modular approach, Magnetorque® Plus sensors can be customised for unique requirements in different applications.
“The Magnetorque® Plus is a result of collaboration with customers to support the requirements for a complete torque and position sensing solution. TT Electronics’ integrated approach is smaller, lighter and more cost effective than alternatives using two separate sensors, while the fully calibrated solution simplifies the route to EPS system design,” said TH Swee, Global Product Line Director within TT Electronics’ Sensing and Control division.
The Magnetorque® Plus torque and position sensing functions are based on Hall Effect technology allowing a truly non-contact design that maximises mechanical durability to support a minimum lifetime of 1 million shaft rotations without degradation of electrical outputs. Dual torque outputs allow accurate diagnostic calculations and availability of custom output slopes.
Unlike most steering sensors on the market, the Magnetorque® Plus offers multi-turn capability, which provides the absolute position of the steering wheel at any time. Instant output at “power-on” provides several benefits, including enhanced accuracy and no standby current. The position output provides absolute multi-turn position information up to ±900° of rotation.
The Magnetorque® Plus is fully calibrated and compensated to offer an easy assembly to the steering shaft with a simple interface to system controllers. Magnetorque® sensors can be re-programmed for offset to accommodate adjustments to the system’s mechanical tolerances, allowing customers to optimise system tolerance for simpler assembly and greater control.
The Magnetorque Plus sensor is available now with pricing dependent on volume.
