By adjusting the opening time and duration of the needle valve, which is controlled by the electronic control unit (ECU) based on various engine operating parameters such as engine speed, load, and temperature, the injector can deliver the exact amount of fuel required for optimal combustion. This precise control helps improve fuel economy, reduce emissions, and enhance engine performance. High-Pressure Fuel Injection: High-pressure common rail injectors are capable of injecting fuel at extremely high pressures, typically in the range of several hundred to over a thousand bar. The high injection pressure atomizes the diesel fuel into very fine droplets, increasing the surface area of the fuel exposed to the air in the combustion chamber. This promotes more complete and efficient combustion, resulting in better engine power output and lower fuel consumption. Multiple Injection Modes: Modern high-pressure common rail injectors can support multiple injection modes, such as pre-injection, main injection, and post-injection. Pre-injection involves injecting a small amount of fuel into the combustion chamber before the main injection event. This pre-combustion helps raise the temperature and pressure in the cylinder, reducing engine noise and vibration during the main injection and improving combustion stability. Post-injection, on the other hand, is used for various purposes, such as controlling exhaust emissions by injecting additional fuel during the exhaust stroke to increase the temperature in the exhaust system, which helps oxidize harmful substances like hydrocarbons and carbon monoxide. Enhanced Engine Startability: In cold start conditions, high-pressure common rail inje
