FUNCTION OF DIESEL FUEL INJECTION
The fuel injection system lies at the very heart of the diesel engine. By pressurising and injecting the fuel, the system forces it into air that has been compressed to high pressure in the combustion chamber.

Common Rail Components
1 High pressure line
2 Leak-off pipe
3 Fuel injection line
4 Fuel injector
5 Pressure limiting valve
6 Common rail
7 SCV valve
8 Fuel pressure sensor
9 Fuel temperature sensor
10 High pressure injection pump
11 Fuel return pipe

Common rail fuel injection pump (supply pump)
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.

Common rail Injector
The integral seals are made of profiled strips of non-reinforced acrylonitrile-butadiene rubber (NBR). They seal axially against the side face of the inner or outer ring († fig. 4a) or radially against the cylindrical surface of the inner or outer ring († fig. 4b). This material has very good engineering properties and shows good resistance to most mineral oils and greases. The permissible operating temperatures of the seal material range from –40 to + 110 °C
