“…Other research organizations that have tested or are now testing LPG vehicles include GM (Hilden et al, 1991), the Southwest Research Institute (Bass et al, 1993), and the AMFA, Auto/Oil AQIRP and CleanFleet programs. This should eventually lead to a significantly improved database for LPG fuel vehicles.…”

This study focused on the computational and parametric research on a single cylinder spark ignition engine using dual-fuel, 100 % gasoline and (10 %, 20 %, 30 %) propane in gasoline on volume basis as an alternative fuel for investigating the performance and emission characteristics of spark ignition engine. The performance parameters Brake power, Torque, Bsfc, and Bmep were examined using Avl Boost software. In addition, the exhaust emissions like nitrogen oxide, carbon monoxide, hydrocarbons were also measured. The (10 %, 20 %, &30 %) of propane in gasoline decreases in power compared to 100 % gasoline, however engine fuelled with 10 %, 20 %, and 30 % propane in gasoline shows reduction in specific fuel consumption. The study investigates the effect of dual-fuel propane and gasoline on a fourstroke single cylinder spark ignition engine. The study was carried out at varying percentage load and varying compression ratio for constant engine speed. The focus of this parametric study tries to investigate the effects of replacing individual gasoline and propane with the optimum mixture of 10 %, 20 %, and 30 % propane in gasoline on volume basis in spark ignition engine in order to improve its performance and emission characteristics.

“…When environmental effects of LPG are taken into consideration compared with those of liquid fuels, significant improvements in exhaust emissions can be achieved . LPG-fueled spark ignition engines produce virtually zero emissions of particulate matter, very little carbon monoxide, and moderate hydrocarbon emissions . A major disadvantage of the LPG is the NO x emission is greater than that for liquid fuels…”

The purpose of this study is to evaluate the effect of water addition on combustion in a conventional SI engine. The manifold induction method is used for water addition in this study. The exhaust emissions, ignition timing, and exhaust temperature values were measured for different equivalence ratio values by using a naturally aspirated liquefied-petroleum-gas-fueled spark ignition, four-cylinder engine. The water induction is accomplished over a wide range of water to fuel mass ratios of 0.2−0.5. The results showed that water addition worked as a cooling mechanism for the fuel−air charge and slowing the burning rates, yielding a reduction of the peak combustion temperature, which in turn provides a 35% reduction in peak NO x emissions without any significant change in CO and HC emissions. In addition, greater ignition advance is obtained.
