“…In this connection, experimental investigations with simulated biogas in SI engine with VCR are reported in Huang and Crookes 21 and Wong. 22 In those studies, it was observed that the efficiency of the engine improves with the increase in CR and the engine attains maximum efficiency for an optimum CR with biogas as fuel. Different authors carried out investigations with biogas fuel and studied the performance of SI engine.…”

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.

“…A review of earlier literature states that the experiments conducted in SI engine comparing the performance between methane and gasoline. (Wong 1977) made investigations carried out on the performance characteristics of methane and gasoline at wide-open throttle engine operation for different speed. It was noted that there was a drop in brake power and fuel consumption for methane compared to gasoline.…”

The implementation of recent emission norms has caused the automotive industries to develop advanced technologies for gaseous fuelled SI engines. This research focused on the comparison of turbocharged Compression Ratio (CR) 10.5:1 and naturally aspirated (NA) 12.5:1 for Compressed Bio-Methane (CBM) fuelled SI engine. The original port fuel injected automotive Compressed Natural Gas (CNG) Spark Ignition (SI) engine with 15.5 kW at 3400 rpm was made to function with CBM fuel under full throttle conditions at given CR. Also, two turbochargers T1 and T2 were analysed and validated using ANSYS turbo-machinery numerical package. T1 generated a higher-pressure ratio than T2 and was preferable. The simulation study outcomes infer that entropy generation for T1 at a 1.3 bar is less than 1.5 bar gave a better transient response. The experimental comparison was made between CR of 10.5:1 turbocharged and naturally aspirated CR of 12.5:1. At CR of 10.5:1, 1.3 bar boost pressure, brake power increased by 19.3%, reduced fuel consumption by 10.1%, and reduced hydro carbon (HC) and Carbon monoxide (CO) emissions 42.9% and 38.3%, when compared to NA CR of 12.5:1. On the whole, the downsized CR of 10.5:1 turbocharging exhibit better performance and reduced thermal loading when compared to higher CR of 12.5:1.
