The number of built-in electronic components is growing steadily and cars have become high-tech vehicles – safer, more comfortable and more environmentally friendly.
Ferdinand Bilstein offers a dynamically growing assortment of spare parts in the electronics and sensor area in OE matching quality, suitable for various vehicle types.
We exclusively carry quality parts, for example, exhaust pressure sensors, EGR valves, ignition coils and air flow meters in our product range.
The purpose of the Exhaust Gas Recirculation (EGR) system is to reduce the emissions of oxides of nitrogen (NOx) from the engine’s exhaust.
There are two main types of EGR Valve. One is vacuum operated, which uses an electropneumatic pressure transducer, controlled by the ECU to open and close. The other is operated by a DC electric motor, or stepper motor. Both electronic and vacuum types are opened and closed subject to engine load.
The Manifold Absolute Pressure sensor (MAP sensor) measures the pressure in the inlet manifold, providing instant manifold pressure information to the engine’s electronic control unit (ECU). The data from the MAP sensor is used to calculate air density and determine the engine’s air mass flow rate.
The data from this sensor can be used for diagnostic purposes as it measures the throttle and turbo performance, as well as to diagnose unmetered air leaks in the inlet manifold.
These sensors measure the speed and position of the cam and crankshaft. Their signal is processed by the engine management ECU to improve the accuracy of the ignition and fuel timing.
The two main technologies used in these sensors are typically of a hall or inductive type. The operations of these sensors are fundamentally similar.
Its signal is used to calculate the injected fuel quantity, and for regulating the exhaust gas recirculation in diesel engines.
There have been several different types of sensor used over the years, depending on the systems vehicle manufacturers used. The two main types are Air Flow Meters, or Air Mass Meters.
The description of Air Mass Sensors and Air Flow Meters are often used interchangeably. However this is incorrect as the Air Flow Meter only detects the air volume, whereas Air Mass Sensors are significantly more precise because temperature and pressure are also taken into account.
There are several design variations of the ignition coil and also the technology used is dependent on a variety of criteria.
The engine management ECU has total responsibility for controlling the throttle valve inside the Throttle Body, with a DC motor to control the throttle valve angle. Feedback is then given to the ECU via a throttle position sensor. Together, these components make up the Electronic Throttle Control.
The throttle control also plays an important role in emissions reduction, particularly in direct injection petrol engines when switching between homogeneous or stratified modes, as well as to control fresh air for the EGR.
At Ferdinand Bilstein, quality control of electronic components is performed using a high-resolution X-ray machine.
In the randomly performed sample inspection of incoming goods, a check is carried out to determine, amongst other things, whether circuit boards, resistors and capacitors are damaged or the wiring may be kinked.
In addition, the connection points to the circuit boards and the soldering of resistors and capacitors are tested.
