SHORT INFO Control valve, camshaft adjustment
PRODUCT FEATURES
Application
Wide range with different part numbers for a variety of vehicle manufacturers: Acura, BMW, Chrysler, Dodge, Ford, GM, Honda, Hyundai, Jeep, Kia, Lexus, Mazda, Nissan, Toyota, Vauxhall.
Design and function
The control valve is an electromagnetic actuator for variable camshaft adjustment and is installed on the cylinder head in the camshaft area. The valve transmits the oil pressure through different channels to the camshaft phaser in accordance with the engine management specifications, which changes the position of the camshaft and changes the timing.
The engine control unit electrically regulates the control valve. There may be one or more control valves installed, depending on the engine concept.
The variable adjustment of the intake and also the exhaust camshafts means that the cylinders are filled optimally, enabling higher power and improved torque characteristics over a certain speed range. In addition, this can reduce pollutants in the exhaust gas and fuel consumption. If the cam adjustment is used as internal exhaust gas recirculation, the nitrogen oxide values in the exhaust gas are also reduced.
APPLICATION EXAMPLES
Five different systems and designations are used, depending on the vehicle manufacturer and engine concept.
[1] Camshaft phaser
