The GDI (Gasoline Direct Injection) high-pressure fuel pump is one of the core components of a direct injection engine. It is responsible for pressurizing the fuel from a low-pressure state to 15-300bar or higher, and then directly injecting it into the cylinder through the common rail and the fuel injector. Main brands: BOSCH Continental/Siemens Denso Delphi The main functions of the CT7000 GDI high-pressure fuel pump test bench 1. Sealing performance test High-pressure and low-pressure sealing tests are conducted to detect whether there is any leakage in the pump body, interfaces, and sealing rings. 2. Traffic test Test the fuel supply flow of the high-pressure pump at different rotational speeds (simulating engine speeds) and pressures. 3. Pressure test Test the speed at which the fuel pump builds the target pressure and the stability of maintaining the pressure under specific working conditions. Fuel Metering Valve (IMV) Control and Testing Test the flow regulation characteristics of the IMV valve under different currents to determine whether the valve body itself is working properly. Technical parameters The test speed is 0 to 3000 revolutions per minute 2. Test pressure: 0-300bar 3. IMV test power supply: 0-30V 0-
