Once again, our sensor group has been expanded with a new member. So far, we have 90 references of pressure converters ready for delivery from our warehouses. The pressure converters are made of OE quality - and in the following you can learn more about the use and function of the pressure converters.
Pressure converters are used - depending on the engine type - at several different locations for pneumatic control of mechanical parts - including the EGR valve and the turbocharger wastegate valve. Based on information from other engine/exhaust system sensors, the position of the valves is controlled via the pressure converters by the vehicle's engine control (ECU).
System build
The pressure converter forms a control pressure by mixing atmospheric air with vacuum from the vehicle vacuum pump. The steering pressure depends on the type of pressure converter - stroke or variable controlled. The required steering pressure - and thus the mixing ratio - is set by the vehicle's engine control (ECU) and is regulated by means of an electrically controlled piston in the pressure converter.
Cross-section of pressure converter
Pressure converters come in different types, which differ, for example, in that they are:
- With or without temperature compensation
- Variable or stroke controlled
- With or without filter at the connection for atmospheric air
