Abstract
The internal combustion engines remain preferred prime movers for on-road and off-road applications over many decades. However, for reducing the usage of fossil fuels and the harmful pollutants emitted by the conventional engines, it has become imperative that the alternative strategies are developed. In this regard, alcohol fuels are established as one of the alternative energy resources for internal combustion engines. Alcohol fuels have many advantages such as presence of fuel-bound oxygen, higher octane number, higher volatility, etc., compared to those of gasoline. The alcohol fuels are considered as the second-generation biofuel, which is employed as alternative fuels for SI engines and the blending of alcohol fuels such as methanol, ethanol, and butanol with biodiesel, also assists in mitigating the biodiesel-NOx penalty in diesel engines. Moreover, the alcohol fuels are effective in advanced combustion strategy like low-temperature combustion (LTC). It is opined that the alcohol fuels make use the full merits of LTC which is attributed to the increased octane number, wider equivalence ratio, broad operational range with reduction in emission, higher auto-ignition resistance, and longer ignition delay. Hence, this chapter is aimed to present significant details on combustion and emission characteristics of alcohol-fuelled engines operated on advance combustions strategy of LTC.
