The aim of this paper is to investigate the emission of a single cylinder diesel engine when being injected with hydrogen gas. The hydrogen gas was produced by alkaline electrolyser, which has multiple separators to separates hydrogen and oxygen gas produced. The input hydrogen gas injected into the single cylinder diesel engine was altered by changing the alkaline electrolyser input voltage. The effects of the hydrogen gas injected into the diesel engine was observed by measuring the emission characteristics. The engine emission was measured in terms of carbon monoxide (CO) and also nitrogen monoxide (NO) in parts per millionth (ppm). The results shows that, as more hydrogen gas was injected, the emission of carbon monoxide (CO) decreases while Oxides of Nitrogen (NOx) increases
