TESTING OF THREE-FUEL MIXTURE IN A FOUR-STROKE SINGLE CYLINDER DIRECT INJECTION DIESEL ENGINE

Sa？etak This paper deals with non-petroleum renewable and non-polluting fuels. The performance study has been carried out for three-fuel mixture in an Internal Combustion engine. The three-fuel mixture consist of diesel, turpentine blend and acetylene gas. Acetylene gas is produced from lime stone (CaCO3) and turpentine oil is obtained from pine trees. The performance of the three-fuel mixture has been analyzed experimentally in a single cylinder direct injection and compression ignition engine with diesel and turpentine blend as primary fuel and acetylene as secondary gaseous fuel i.e., diesel and turpentine blend (40% turpentine(40T) and 60% diesel) were considered for the study. The results have shown that the blend and the acetylene gas flow rate of 3 liters per minute (through a gas flow meter) offer higher brake thermal efficiency by between 1% and 3% than the fuel of the baseline diesel operation
