Nozzle is a mechatronics product, and there are not as many mechanical linkage parts and wearing parts (such as diaphragm and needle valve) as carburetor. Its internal structure is relatively simple, so the work is more reliable, the failure rate is lower, and the daily maintenance is simpler. ECU continuously monitors and adjusts the air-fuel ratio through the fuel injector to ensure that the engine can obtain stable and appropriate fuel supply under various working conditions, especially at idle speed. This makes the engine run very smoothly, with little jitter and low noise, and improves the ride comfort. The fuel injector can be opened and closed at a very high speed, realizing accurate instantaneous fuel injection. When the driver steps on the accelerator, the ECU can immediately increase the fuel injection, and the engine has a very rapid dynamic response, without the delay feeling like a carburetor, which improves the driving experience. The electronically controlled fuel injector is precisely controlled by the ECU, which can calculate the most suitable fuel injection quantity and timing according to the real-time working conditions of the engine (such as speed, load, temperature, etc.), realize "on-demand fuel supply", avoid unnecessary fuel waste of the carburetor, and thus significantly improve fuel economy. 0445110290 3380021900 3380027000 3380027900 Common Rail Injecto Compatible For Hyundai Kia D4EA Fuel Injector Nozzle, Manufacturer: Hashengtengbaihuo
