“…The fuels such as raw biogas, producer gas, and methane are derived sources from biomass which make them nonconventional fuels. In this regard, various researchers 8,17–20 studied the effect of VCR on the performance and fuel consumption of the LPG, natural gas, and producer gas on spark ignition (SI) engines. Ozcan and Jehad 17 considered variable stroke length of a LPG-based single cylinder four-stroke SI engine to evaluate optimum bore-to-stroke ratio for maximum performance.…”

The present experimental investigations deal with the spark plug location and its effect on the performance and emission of a 100% raw biogas-fueled variable compression ratio engine. Different measurements of performance, combustion, and emission parameters are used to analyze the effect of four spark locations protruded inside the clearance volume (viz. 0, 2, 5, and 10 mm). The protrusion of the spark plug by 2 mm is observed to be optimum for compression ratios 8, 9, and 10. For this optimum spark plug location, engine efficiency and fuel economy are found to be higher. Faster combustion, in this particular case, has led to early and higher peak cylinder pressure and burnt gas temperature. Lower emissions of hydrocarbons and carbon monoxide have verified the optimality of 2 mm protrusion location of the spark plug for all the compression ratios. Thus, present investigations recommend minor protrusion of the spark plug to assist the combustion process, to enhance the performance and lowering the emission of a biogas-fueled engine.
