### **Abstract**

Biofuels have caught the eye of engine specialists as far back as the oil emergency and heightening expenses of petro-synthetic compounds cropped up in the 1970s. Ethanol and methanol were the most broadly inquired alcohols in IC engines. Higher alcohols are alluring second/third era biofuels that can be created from sugary, dull and lignocellulosic biomass feedstocks utilizing reasonable pathways. Developing worries of petroleum product consumption, oil-value variances, heightening vitality requests and stringent discharge guidelines are driving established researchers to discover elective sustainable biofuels for use in diesel engines. Among the biofuels like biogas, bioalcohol and biodiesel, alcohol is by all accounts generally appealing. Biogas requires high weight for its utilization in vehicle and its spillage can be risky. Biodiesel from consumable vegetable oil can cause insufficiency in sustenance supply. Everything being considered, the utilization of lower alcohols like methanol and ethanol in slow speed engines shows certain complexities because of their low cetane number, high inert warmth of vaporization and high protection from auto-start. Further the less calorific respect and poor miscibility with diesel limit their utilization in diesel motors.
