The aim of this research is to compare fuel consumption from standard fuel injection systems with high-pressure fuel injection systems in agricultural single-cylinder diesel engines. In the experiment,modifications were made to the fuel injection system by using a high-pressure pump and a high-pressure rail (common rail).The fuel injection of the injector is electronically controlled. The high-pressure pump is driven by a test engine, Experiments were conducted to compare fuel consumption between standard fuel injection systems and high-pressure fuel injection systems. In addition, the fuel injection pressures were varied from 300 bar, 400 bar, and 500 bar at engine speeds of 1,200 rpm, 1,600 rpm, and 1,800 rpm. The results showed that fuel injection pressure affects the fuel consumption rate and emissions of the engine.High-pressure fuel injection will have lower fuel consumption than standard fuel injection cases when the engine is loaded. In terms of emission results, it was found that if the engine is loaded, the high-pressure fuel injection system would be less polluting than the standard fuel injection system, which will increase if the load on the engine is increased.
