The purpose of this study is to analyse the combustion and emission characteristics of a heavy-duty single cylinder engine (HDSCE) with a mixer and a liquefied petroleum injection (LPi) system. The mixer and LPi systems provide liquefied petroleum gas (LPG) in vapour and liquid phases throughout the intake manifold. Sensors such as the crankshaft position sensor (CPS) and Hall sensor supply spark and injection timing data to the ignition controller. An HDSCE runs at an engine speed of 800–1400 r/min, a compression ratio (CR) of 8, and a relative air-fuel ratio (Λ) value of 0.8–1.3. The major conclusions of this work include: LPi and mixer systems exhibit similar brake specific fuel consumption (b.s.f.c.) levels of 275g/kWh. Fuel efficiencies of LPi and mixer methods are almost identical. All these methods exhibit generally similar CO emission properties, and LPi wide-open throttle (WOT) and mixer WOT methods exhibit similar NOx emission properties.
