Injectors are small electronic components that are used to produce a spray of fuel into the intake conduit in front of the inlet valve of a diesel engine. Diesel nozzles are quite complex; the injector has a large upper micron filter inlet side, which corresponds to small subcutaneous large holes in the bottom of the injection of diesel fuel. Diesel fuel acts as a lubricant source for the inside of the fuel injector. When the water displaces fuel lubricity of the interior of wear out quickly and the injector as a whole may fail fairly quickly.
Injectors are crucial engine components. A nozzle valve opens and closes at the same speed as diesel. This corresponds to approximately 140,000 times per hour! In addition, the water is exposed to the fuel injectors of coal particles and dirt from entering the air filter element to drive the poor. Type of fuel quality and additives used also has a significant impact on the lifetime of the fuel injector. ECM (Engine Control Module) controls the fuel injectors in most diesel-electric. Diesel nozzles are permanently in power when the key is turned on, whether the engine is turned. ECM grounds the injector ready for the circuit and causes the fuel injector to open. ESM after receiving the information from various sensors to control determines the time required for the earthling of injectors to inject the correct amount of fuel the demand horsepower engine power.
The process of diesel fuel injectors opening, closing and feeding the right amount of fuel takes place in milliseconds. Cars jets are much smaller than in heavy-duty diesel and measured in cubic centimeters. There are two types of diesel fuel injectors: the first is called a throttle body injection, with 1-2 injecting mass of the gas of a diesel engine and measured delivery of the amount of spray fuel into the intake manifold. This delivery system is substantially loaded with intake and intake valve draws fuel into the engine cylinders. Port injection type is more effective than the gasified, since it adapts to the air density and height, and is not dependent on the vacuum manifold assembly.
The gas-injection spray becomes ineffective when the cylinder closest to the injectors, which has a good mix of these, which are outermost.
