In combination with the crankshaft sensor, it allows the ECU to identify the position of the first cylinder’s piston, but more importantly its combustion cycle. This allows the engine management system to inject fuel into the right cylinders at the right time – ultimately to achieve better engine efficiency.

Magnetic flux variations are detected by the gear (or ferromagnetic target) positioned in front of the camshaft sensor – the same principle actually applies to the crankshaft sensor. These two sensors then convert the variations into electrical signals and send them to the ECU, which interprets them to determine the amount of fuel to be injected into the intake valves, as mentioned above.

As the European market leader in engine management sensors, our Group has acquired an extensive expertise in both technologies. Choosing our camshaft sensors therefore means choosing the quality of an Original Equipment Manufacturer (OEM) recognised for its expertise by the world’s leading manufacturers.

The fuel pressure sensor is located on the vehicle’s common rail injection system. For reference, this rail supplies fuel to the engine’s combustion chamber

Also known as the common rail pressure sensor, its role is to transmit the fuel pressure at the inlet of the fuel rail to the ECU in order to create the perfect fuel dosage for combustion and thus reduce pollution and fuel consumption.

The measured information is then directly transmitted to the ECU – which then adjusts the fuel injection according to the measurements.

This sensor is one of the most exposed technical parts of the vehicle (dirt, dust or heat), and therefore one of the most sensitive parts that will need to be replaced most often.

We offer these sensors in retail, whereas they are sold exclusively with the common rail by the manufacturers. This makes our range the ideal solution for our customers.

An essential part of the ignition system, the coil’s basic function is to transform the battery’s low voltage energy into a high voltage signal (30,000V), thus generating a spark at the spark plug terminals which will allow the ignition of the air/fuel mixture. It is thus directly involved in the combustion process in a petrol engine.

Designed for use in ignition in more severe combustion chamber conditions, its main advantages are improved fuel efficiency, reduced weight and size of the ignition function, and ease of installation on the engine.

Over the years, there have been many generations of coils: from the oldest “classic” oil system to the latest generation of individual coils, connected directly to the spark plug, to ramp or twin coils.

With more than 60 years of experience in the field of ignition, our expertise is well established. By putting this know-how to good use, we offer you a 3-year warranty extension on our entire range of coils beyond the 2-year period already in force.

Located along the exhaust line (as its name implies), the temperature sensor measures the exhaust gases’ temperature in order to limit pollutant emission. This information is transmitted directly (via a voltage signal) to the electronic control module (ECM) in order to optimize combustion – to make it as clean as possible, either by adapting the air/fuel mixture, or by initiating a regeneration of the diesel particulate filter (DPF).

Originally protecting only the catalytic converter, in the exhaust system, the exhaust gas temperature sensor’s role is pivotal. As a matter of fact, it also protects the components in the exhaust gas stream, which are exposed to extremely high temperatures. The sensor is capable of measuring temperatures ranging from -40 to +900°C and its presence in a particularly harsh environment exposes it to a high risk of failure (compared to other sensors).

Due to increasingly strict anti-pollution standards, modern vehicles (petrol and diesel engines) are equipped with several sensors. Generally, they have at least 3 sensors, one before the turbocharger, one before the DPF and one after the DPF.

The role of these sensors is to help the driver park their vehicle by alerting them to the immediate proximity of a possible obstacle. For this purpose, they use ultrasonic technology, and although they have long been referred to as “reversing sensors”, this is no longer the case, since they are increasingly also present at the front of the vehicle.

In concrete terms, when these sensors detect an obstacle, the driver receives a visual and/or acoustic signal, which becomes more and more pronounced as the distance is reduced. It logically follows that the more sensors are installed, the more accurate the measurement is.

In the passenger compartment, as mentioned earlier, the driver can be alerted by acoustic signals alone; this is especially the case on older vehicles. Then, manufacturers moved on to LED indicators and, more recently, graphic displays on the multimedia system screen – and if not, simply a coupling of the information from these sensors with the video display of a parking assistance camera.

The frequency of the signal increases as the distance to the obstacle decreases, and shifts from a distinct “beep” to a continuous sound at about 25 centimetres.
