Company Introduction
Raptors, the authorized dealer of Cummins (China), established in 2015 by Mr. Jordan Wang who worked in Cummins (China) for 8 years, Jordan had been responsible for mine market for 4 years during working in Cummins china, so we have big advantages for almost all genuine Cummins generators, engine assembly and spare parts, especially for NTA855, KTA19, KTA38, KTA50, QSK60, QSX15 etc...Fuel Injector The fuel injector itself is a normally closed valve (normally closed valve means that when no control signal is input, the valve is always closed; and normally open valve is when there is no input control signal, the valve is always open), by A valve needle moves up and down to control the opening and closing of the valve. When the ECU issues a fuel injection command, its voltage signal will cause the current to flow through the coil in the fuel injector to generate a magnetic field to suck up the valve needle, so that the valve can be opened so that the fuel can be ejected from the fuel injection hole. The biggest advantage of injection fuel supply is that the control of fuel supply is very precise, so that the engine can have the correct air-fuel ratio in any state, which not only keeps the engine running smoothly, but also the exhaust gas can meet the environmental protection regulations.
