Diesel Injector Nozzle DLLZ157P964 Fuel Injection Nozzle Auto Engine Systems Vehicle Parts

The precision of the injector nozzle has a crucial impact on the performance of the automobile engine, which is mainly reflected in the following aspects:

Power output
High-precision injector nozzle can accurately control the amount of fuel injection. Under different working conditions of the engine, such as idling, acceleration, high-speed cruising, etc., different amounts of fuel are required. If the nozzle is highly accurate, it can accurately inject the right amount of fuel into the cylinder according to the instructions of the engine control unit (ECU). For example, when the vehicle accelerates, the nozzle can accurately increase the amount of fuel injected, so that the mixing ratio of fuel and air reaches an optimal level, thus ensuring that the engine can output enough power and the vehicle can accelerate quickly and smoothly.

On the contrary, if the precision of the nozzle is not enough, the fuel injection volume may be deviated. When the injection amount is too much, it will lead to the fuel can not be fully combusted, part of the fuel is wasted, but also may cause the engine detonation. The detonation is due to the abnormal early combustion of fuel in the cylinder, which will cause the engine to shake, unstable power output, and long-term damage to the internal parts of the engine. And when the amount of injection is too small, the engine will be underpowered and the vehicle will accelerate weakly.

Fuel Economy
The precise amount of fuel injection helps to improve fuel economy. During normal driving, high nozzle precision ensures that fuel is injected into the cylinders in the most economical way so that fuel can be fully burned. For example, under frequent start-stop conditions on city roads, high-precision nozzles can accurately control the amount of fuel injected each time according to changes in vehicle speed and engine load, avoiding unnecessary fuel waste and thus reducing fuel consumption.

Low-precision nozzles may lead to excessive fuel consumption. If the nozzle cannot accurately control the amount of injection, it may continuously inject too much fuel, making the vehicle's fuel consumption increase significantly, and in the long run, the owner's fuel costs will rise significantly.
