A engine performs a mechanical function by converting various energy forms, such as thermal energy, chemical energy or electrical energy, for example.

Usually, motors have a shaft that is set into rotation by this energy. The shaft drives a mechanical device, e.g. a transmission.
However, there are exceptions to this standard design – e.g. rocket engines and linear motors.

Today, combustion engines and electric motors are of particular importance in the area of transport technology. Combustion engines mix fresh air with a combustion medium such as petrol, gas, diesel or heavy oil and ignite this mixture.

A superior driving experience combined with lower consumption and reduced emissions – we are committed to achieving best-in-class results. Our proportional solenoid ensures favorable positioning  of the camshaft angle to the crankshaft angle, helping premium engines to achieve higher torque at lower speeds. In minimal space, with few assemblies, narrowest tolerances, low hysteresis, high dynamics and minimal inductivity.

Optimization of the lubricating-oil circuit through adjustable oil pumps substantially improves both engine efficiency and fuel efficiency – with only small additional costs. This cost-effective solution can be further enhanced through electro-hydraulic adjustment of the control pressure. Thus, in the case of a high engine load it is possible to operate with higher pressure, while lower pressure can be used in the case of a low engine load. Our control valves and solenoids have been specifically designed for this oil sump application. They can effortlessly withstand the temperatures, vibrations and impurities associated with this key component.

Drivers of heavy diesel trucks can protect the vehicle's conventional wheel brake through targeted operation of the engine brake, particularly on long downhill stretches: the compression resistance of the engine reduces the vehicle’s kinetic energy. In order to achieve this, our on-off valve activates a hydraulic cylinder, which in turn opens and closes the engine’s delivery valve.
