Bosch Common Rail Injector With Seal Ring (445117021)

This Bosch Common Rail Injector (0445117021) is a crucial part of the fuel injection system.

The Common Rail Injector enables electronic control of injection timing and quantity to deliver the optimal amount of fuel for each engine cycle, leading to better performance and efficiency.

The common rail type pump has been developed to meet strict exhaust gas regulations in the 21st century. This system consists of a supply pump, common rail, electronically controlled injectors, various sensors to detect the running condition of the engine and a computer (ECU) to control these devices. The supply pump is driven by the engine and produces high-pressure fuel. An injector is mounted on each cylinder of the engine and the high-pressure fuel from the supply pump is distributed to each injector by the common rail.
