...Technical Information Camshaft sensor General Camshaft sensors have the function, in coordination with the crankshaft sensor, to define N o 1 cylinder compression/firing stroke. This information is needed for a) commencement of injection on sequential injections system, b) th...

...Technical Information Coolant level sensor General Coolant level sensors are fitted into the expansion tank. It checks the minimum level in the tank to prevent an overheated engine through water shortage. Function The coolant level sensor is a magnet which is...

...Technical Information Coolant temperature sensor General The coolant temperature sensor provides information for air/fuel mixture preparation by recording the operating temperature of the engine. The ECU adapts the injection time and the ignition angle to the operating conditi...

...Technical Information Crankshaft Sensor General Crankshaft sensors record the engine speed and crankshaft position. The fitting position is near the flywheel ring gear. More they are found on the engine block with the sensor ring bolted onto the crankshaft There are two differen...

...The Diesel Particulate Filter System DPF General information In order to maintain the prescribed emission limit values, a diesel particulate filter that is also known as DPF is used in vehicles with diesel engines. The diesel particulate filter comprises a ceramic structure that ha...

...Technical Information Idle speed control valve General The idle speed control valve is bypass valve. Example, as shown, is for Opel. It is made of a cast housing with a magnetic valve servo unit. A jet stem is fitted to the servo unit. Through the movement of the servo unit th...

...Technical Information Ignition module (Trigger box) General The ignition module contains the closed -loop primary current control circuit and the dwell-angle control. They are built with hybrid technology. This has the benefit that they can be built together with the igniti...

...Technical Information Injectors General Injectors have the task, during all driving conditions, to inject the correct amount of fuel calculated by the ECU. For good fuel atomisation and small condensation loss an engine specific distance to the inlet valve and injection angle a...

...Technical Information Inlet Air Temperature (IAT) Sensor General IAT sensors sense the air temperature on the inlet side of the engine. The voltage signal, produced by the sensor, is passed to the ECU. The ECU evaluates the signal and influences the fuel injection timing and ignition t...

...Technical Information Knock Sensor General You can find the knock sensor mounted on the side \ of the engine block. It recognises knock or pinging under all engine operating conditions to avoid lack of performance....
