Diesel Parts (18)

Bosch eXchange common rail injectors

Bosch eXchange injectors inject fuel right into the combustion chamber. Common rail injectors work with a maximum injection pressure of up to 2700 bar. They are remanufactured in strict compliance with the same production standards as new parts which ensures a long lifetime.

Bosch eXchange common rail pump

In common rail systems, Bosch high-pressure pumps compress the fuel to up to 2700 bar and reliable provide the required quantity. They are remanufactured in strict compliance with the same production standards as new parts which ensures a long lifetime.

Bosch eXchange distributor-type injection pump

Due to their compact design, Bosch eXchange distributor-type injection pumps can be used for diverse application purposes in passenger cars, commercial vehicles, stationary engines as well as construction and agricultural machinery. They are remanufactured in strict compliance with the same production standards as new parts which ensures a long lifetime.

Bosch eXchange nozzle-and-holder assembly

Bosch eXchange nozzle-holder assemblies are needed to inject fuel into the combustion chamber of diesel engines.They are remanufactured in strict compliance with the same production standards as new parts which ensures a long lifetime.

Bosch eXchange unit injector

Bosch eXchange unit injectors are part of an electronically controlled diesel direct injection system. At unit injector systems, the single-plunger pump and the injection nozzle are combined into a single unit. They are remanufactured in strict compliance with the same production standards as new parts which ensures a long lifetime.

Common rail injectors

The fuel is distributed directly into the combustion chamber by the common rail injectors. The injectors are supplied with fuel from the rail by short high-pressure lines. There is a valve inside the injectors which activates the injection nozzle.

Common rail pump

At common rail systems, the high-pressure pump compresses the fuel to up to 2700 bar and provides the amount required. For this purpose, it constantly supplies the high-pressure rail with fuel and maintains a consistent system pressure. As the pressure build-up is not linked to the engine speed, the pressure required is thus available even at low engine speeds.

Denoxtronic dosing module

Bosch Denoxtronic permanently aligns the AdBlue® dosing with the actual operating condition of the engine and current exhaust-gas values.The dosing module ensures a precise AdBlue® quantity control and handles its atomization and distribution within the exhaust pipe.

Denoxtronic supply module

Bosch Denoxtronic permanently aligns the AdBlue® dosing with the actual operating condition of the engine and current exhaust-gas values. This technology helps vehicle manufacturers in several countries to comply with applicable emission limits. The supply module generate the required AdBlue® pressure and delivers the pressurized reduction agent to the dosing module.

Departronic injection unit

Unlike pure engine-internal measures of particle reduction, such as post-injection for instance, Departronic doses and injects the fuel upstream of the oxidation catalytic converter and the diesel particle filter. The injection unit ensures a precise fuel injection and handles its atomization and distribution within the exhaust pipe.

Departronic metering unit

Unlike purely engine-internal measures of particle reduction, such as post-injection for instance, Departronic doses and injects the fuel upstream of the oxidation catalytic converter and the diesel particle filter. The metering unit determines the required dosing quantity and forwards it to the injection unit.

Distributor-type injection pump

Due to their compact design, distributor-type injection pumps can be used for diverse application purposes in passenger cars, commercial vehicles, stationary engines as well as construction and agricultural machinery. They consist of a small, compact assembly containing the supply pump, the high-pressure pump and the regulator.

In-line diesel injection pump

In-line injection pumps allow high cylinder outputs at 2-to-12-cylinder engines. They are used in engines of commercial vehicles, construction and agricultural machinery as well as for stationary engines. Their name is based on the pump cylinders arranged in lines. At engines equipped with this pump, each cylinder is supplied with fuel by an own pump element and via a pressure valve and a high-pressure line.

Nozzle-and-holder assembly

A nozzle-and-holder assembly (NHA) consists of a nozzle holder, an injection nozzle, a nozzle clamping nut and different smaller bits and pieces (e.g. spring, pressure bolt, shim washer). Nozzle-holder assemblies are needed to inject fuel into the combustion chamber of diesel engines.

Pressure valves

Valves are among the most strained components of injection systems. Therefore, the high production quality is important. Especially valve pistons and pieces have to fit into one another accurately. As one of the world’s largest OE suppliers and diesel system developer, Bosch provides pressure valves with excellent quality both as original equipment and on the aftermarket.

Pump elements

Each cylinder of an in-line injection pump is supplied with fuel by an own pump element and via a pressure valve and a high-pressure line. The pump runs synchronously with the pistons – that is, half as fast as the engine. To ensure this performance throughout hundreds of thousands of kilometers of operation, Bosch pump elements feature a particularly high material and production quality.

Unit injector system

The unit injector system (UIS) also known as pump/nozzle system is an electronically controlled diesel direct injection system developed by Bosch. At unit injector systems, the single-plunger pump and the injection nozzle are combined into a single unit.

Unit pump system

The unit pump system (UPS) is used for commercial vehicles only. It uses a pressure pump for each cylinder. Therefore, the system also known as “pump/line/nozzle” system is closely related to the unit injector system (UIS). In the UPS in fact the nozzle holder combination and the injection pump are connected via a short high pressure connection.
