Abstract

This research aims to retrofit a compression-ignition engine for the direct injection of ammonia into the engine cylinder with pilot injection of biodiesel. The Lifan engine with a displacement of 418 cc and a maximum power output of 7.2 kW was selected. The engine was modified to direct ammonia injection, involving the installation of a GDI injector for ammonia injection, and common rail injector for biodiesel injection . Additional adaptations included the installation of a common rail system, temperature sensors at specific engine areas, a crankshaft and camshaft position sensor, and the utilization of two ECUs. The ammonia fueling system includes pipes, flowmeters, pressure and temperature sensors, tanks, safety installation, etc. (Fig. 1). The emissions in exhaust gases was measured using a Fourier Transform Infrared Spectroscopy (FTIR) from Gasmet company. The sprays, emissions formation, and combustion characteristics of biodiesel and ammonia have been investigated by CFD models [3].
