Product Description

Diesel injectors operate with a fuel supply line, an intake valve, an exhaust valve and a fuel injection apparatus. Each cylinder has its own fuel supply line running from the fuel tank to the engine. As the fuel journeys to the engine, it passes through a filter where impurities are removed. At the injector device, it becomes pressurized and is sprayed through a nozzle into the cylinder's combustion chamber. An air intake valve sucks air into the chamber, which mixes with the vaporized diesel fuel and intensifies the combustion. An exhaust valve removes the resulting emissions from the combustion chamber, and excess fuel is returned to the fuel tank. Bosch manufactures a replacement diesel injector for the 1985-1986 BMW 524td.
