Nikki LPG injector assembly for Nissan K21 and K25 propane engines, metering LPG vapor into the intake as part of the fuel delivery system. It introduces fuel in the controlled amount the engine calls for, supporting the correct air-to-fuel balance across idle, acceleration, and working load. It commonly serves UniCarriers, Komatsu, Caterpillar, and Mitsubishi trucks built around the K21 and K25 platform.
Built by Nikki for Nissan K21 and K25 propane engines, this injector assembly meters LPG vapor into the intake as part of the engine's fuel delivery system. It introduces fuel in the precise amount the engine calls for at any moment, holding the correct air to fuel balance across idle, acceleration, and full working load. Accurate metering at this point is what underpins clean combustion, steady power delivery, and dependable starting on propane.
Because the K21 and K25 are shared powerplants, this injector serves a wide range of trucks built around them, including UniCarriers, Komatsu, Caterpillar, and Mitsubishi lift trucks along with Nissan's own. A worn or contaminated injector shows up as hard starting, rough idle, hesitation under load, or a fuel mixture the engine can no longer hold correctly, and replacing it restores the metered fuel delivery the engine was designed around.
Match the injector to the K21 or K25 engine in your truck, since the assembly is specific to that engine platform's fuel and intake arrangement.
