Diesel piezo injector driver circuit

 · The injectors for a gas engine are 12v with a switching ground to actuate the injector. In the diesel i will need to switch the positive with a constant grounding source. That in itself is easy enough really. The voltage used on the diesel injectors is much higher though. I need to come up with a circuit that will output up to v preferably.  · Current is supplied to the ECU driver circuits (#10 and #20 in example) through the fuel injectors. Current flows either directly from the ignition switch or from the EFI Main Relay. When the ECU driver circuit turns on, current flows to ground through the injector solenoid coil.  · Piezo injectors (indirect drive) The piezoelectric actuator, the extension of which is amplified hydraulically, acts on a pilot valve that opens to download the environment upstream of the needle, which then will rise due to the effect of the pressure of the fuel in the delivery chamber.

Current flows either directly from the ignition switch or from the EFI Main Relay. When the ECU driver circuit turns on, current flows to ground through the injector solenoid coil. CRD (Bosch) piezo injector circuit current. The purpose of this test is to investigate piezo injector circuit current changes during idle, acceleration and overrun conditions. WARNING. This test involves measuring a potentially hazardous voltage. Please ensure you follow manufacturers' safety instructions and working practices and ensure the rated voltage for all accessories you are using meets or exceeds the expected voltage.

Electronic control of diesel engines for passenger cars and commercial vehicles is a critical function in today"s automotive industry. Controller Area Network (CAN): Licence of Robert Bosch GmbH diesel direct injection system with coil driven injectors. Further different approaches to. Fig. 3 shows the common rail injector driver circuit, which consists of a microprocessor, a transistor, and a diode. The total fuel injection duration is.
