Bosch Common Rail Pump CP4 Roller

1.What’s Bosch CP4 Pump?

The Bosch CP4 pump is a type of high-pressure fuel injection pump used in diesel engines. It is manufactured by Bosch, a leading supplier of automotive components.

The CP4 pump is designed to deliver fuel at extremely high pressures to meet the requirements of modern diesel engines. It is commonly used in vehicles with common rail direct injection (CRDI) systems, which are known for their efficiency and improved fuel atomization.

The CP4 pump operates by drawing fuel from the fuel tank and pressurizing it to a high level before delivering it to the fuel injectors. The high-pressure fuel is then injected into the engine cylinders at precise intervals and in precise amounts, resulting in efficient combustion and power generation.

2.What’s Bosch CP4 pump roller?

CP4 pump roller is a specific component within the Bosch CP4 fuel injection pump used in diesel engines. The CP4 pump roller is a cylindrical component that plays a crucial role in the operation of the pump.

Inside the CP4 pump, the roller is responsible for pushing against a camshaft lobe, which helps generate the high-pressure fuel required for efficient injection into the engine cylinders. As the camshaft rotates, the roller follows the contour of the lobe, converting the rotary motion into a reciprocating motion. This reciprocating motion creates pressure within the pump and enables fuel delivery at high pressures to the engine’s fuel injectors.
