2L90/2L92/2L95F Type twin-cylinder diesel engine fuel injection pump features a roller tappet structure and parallel plunger design, suitable for the 2L90/2L92/2L95F in-line air-cooled twin-cylinder engines produced in China

The 2L90, 2L92, and 2L95F fuel injection pumps are engineered for twin-cylinder diesel engines such as the 2L90F, 2L92F, and 2L95F models. Featuring a parallel plunger layout with diameters of 6.0 mm, 7.0 mm, and 7.5 mm respectively, this series is optimized for engines operating at 3000–3600 RPM with output ratings of 14–15 kW. Precision machining and plunger synchronization keep fuel delivery deviation within ±1.8%, ensuring balanced injection to both cylinders for enhanced combustion stability and efficiency.
Designed with a durable roller tappet mechanism and a top-clearance plunger structure, the pump achieves sustained injection pressures ranging from 35 to 55 MPa. This pressure profile is ideal for engines using a direct injection system with a high 19.5:1 compression ratio, supporting fine fuel atomization and cleaner combustion.
The pump includes an M12x1.5 oil outlet joint and an 8 mm inner diameter rubber hose inlet, offering compatibility and ease of integration. A built-in mechanical centrifugal governor keeps speed regulation within a tight ±5% range, delivering steady fuel flow even during fluctuating engine loads, making it highly suitable for generator sets, agricultural engines, and industrial diesel units requiring stable output.
Robust in design and refined in control, the 2L90/2L92/2L95F injection pump provides a dependable and efficient solution for modern small to mid-size diesel power systems.
