Diesel fuel injection parts and systems

Ensure quiet, highly efficient combustion in any driving situation: The common rail injectors from the Bosch eXchange program undergo a stringent release process. Thanks to their good price-performance ratio, they provide a high-quality alternative for value-based vehicle repairs on passenger cars and commercial vehicles.

Ensure quiet, highly efficient combustion in any driving situation: The Bosch common rail injector precisely injects fuel directly into the combustion chamber.

Always ensure a constant supply of fuel at precisely the required injection level, whatever the driving situation: The Bosch common rail pump compresses fuel up to 2700 bar and provides the exact amount required. Expertly engineered for smooth operation, high engine performance, low fuel consumption and Constant optimum rail pressure, even at low speeds.

Ensure efficient exhaust-gas treatment: The Bosch Denoxtronic dosing module’s demand-based injection of AdBlue into the exhaust system helps reduce nitrogen oxide emissions. The Denoxtronic dosing module contributes to reducing nitrogen oxide emissions to comply with the emissions’ standards.

Ensure efficient exhaust-gas treatment: The Bosch Denoxtronic supply module is part of the system responsible for delivering AdBlue to the exhaust system, to reduce nitrogen oxide emissions.

For a high-performance, versatile injection system: A Bosch distributor-type injection pump’s compact design enables diverse applications in cars, commercial vehicles, stationary engines and heavy plant machinery. Electronically controlled injection with electric supply pump provides accurate fuel dosing through variable injection pressures and injection timing.

Ensure higher cylinder outputs while using less fuel and reducing emissions: The Bosch in-line diesel injection pump is used in commercial vehicles, construction and agricultural machinery and stationary engines.

Ensure top performance with precise fuel injection into the combustion chamber: Select a Bosch nozzle-and-holder assembly to match delivery rate, spray form and injection pressure requirements. Proven, robust technology and design with wide selection of assemblies for use with all conventional systems and types of engine, from single-cylinder to car and truck.

For assured peace of mind: Bosch pressure valves are made with very high precision, using premiumg materials, both of which are essential requirements for one of the most strained components of an injection system. Valve pistons and pieces perfectly fit into one another for low friction losses. Made of high tenacity materials with additional tempering or hard chromium plating for increased service life and consumption benefits.

Ensure top power and save fuel: The Bosch unit injector system is a nozzle holder assembly with integrated high-pressure pump, providing injection pressures up to 2,200 bar for optimal air/fuel mixture. The main peculiarity of unit injector systems is their design with an individual pump for each cylinder. For this purpose, both the pump and the injection nozzle are combined into a single unit installed right into the cylinder head. Bosch Unit Injector system is expertly engineered for high and optimized engine performance and low fuel consumption.

For top power and fuel efficiencies for commercial vehicles only: The Bosch unit pump system is a high-pressure pump with separate nozzle holder assembly, providing injection pressures up to 2,200 bar for optimal air/fuel mixture. The main peculiarity of unit pump systems is their design. Like unit injector systems, they use an individual pump for each cylinder. Unlike UIS, however, pump and injection nozzle are not combined into a single unit. They represent two separate devices instead. A short line connects them with one another. Bosch Unit Pump system is expertly engineered for high and optimized engine performance and low fuel consumption.
