The fuel injector is a precision device with very high machining accuracy, which requires a large dynamic flow range, strong anti-clogging and anti-pollution capabilities, and good atomization performance. The fuel injector receives the fuel injection pulse signal sent by the ECU and precisely controls the fuel injection quantity.
The spray characteristics of the injector include atomization particle size, oil mist distribution, oil beam direction, range and diffusion cone angle. These characteristics should meet the requirements of the diesel engine combustion system, so that the mixture formation and combustion can be perfected, and high power and thermal efficiency can be obtained.
