The Denso HP5 22100-0E020 is an advanced-generation common rail pump designed for Toyota 1GD-FTV (2.8L) and 2GD-FTV (2.4L) diesel engines. It supports common rail systems with pressures up to approximately 2,500 bar (depending on application calibration) and features a pre-stroke control valve for active discharge control. Available as single-cylinder (HP5S) or dual-cylinder (HP5D) variants, it […]

The Denso HP4 294050-0123 functions as a second-generation medium-duty common rail high‑pressure pump that Denso specifically engineered for Isuzu 4HK1 and 6HK1 diesel engines. Unlike the Denso HP3’s two-plunger design, the HP4 features three plungers positioned at 120° intervals, providing approximately 1.5 times higher fuel delivery capacity than the HP3 while maintaining a maximum system

The Denso HP3 294000-0901 is a second-generation common rail high-pressure fuel pump used in Toyota 1KD-FTV and 2KD-FTV diesel engines (Hilux, Hiace, Dyna). It can generate up to 1,800 bar fuel pressure using a two-cylinder radial piston design with an integrated SCV (Suction Control Valve). The most common failure causes include: Typical symptoms include: With proper maintenance, lifespan can

The Bosch CB18 high-pressure pump 0445025084 is a second-generation common rail diesel fuel injection pump designed for light commercial vehicles and off-highway applications in emerging markets. It features an in-line twin-plunger design and operates at system pressures of 1,400–1,600 bar (140–160 MPa). Unlike fuel-lubricated CP3 pumps, the CB18 uses an engine oil lubrication system, which

The Bosch CP3 high-pressure fuel pump 0445020300 is a third-generation common rail diesel injection pump featuring a three-plunger radial piston design driven by a cam ring. It is capable of generating fuel system pressures typically up to 1,600 bar (23,206 PSI), depending on ECU calibration and application. Note: In certain system configurations utilizing 1,500-bar pressure sensors, the
