As a fundamental study on LPi system application to heavy duty LPG engine, engine output and combustion performance were investigated with various operating conditions using a single cylinder combustion engine equipped with LPi fuel supply system. Experimental results revealed that no problems were occurred in application of the LPG fuel to heavy duty engine, and that volumetric efficiency and engine output, by 10% approximately, were increased with the LPi system. It was resulted from the decrease of the intake manifold temperature through liquid phase LPG fuel injection. These results provided an advantage in the decrease of the exhaust gas temperature, in the control of knocking phenomena, spark timing and compression ratio. The LPi engine could normally operated under λ =1.5 or EGR 30% condition. The optimized swirl ratio for the heavy duty LPG engine was found around Rs = 2.0.
