Abstract: The 3-cylinder engine consist of three cylinders, two cylinder of same volume called HIGH-PRESSURE CYLINDERS (fired cylinders) both connected to third cylinder called LOW-PRESSURE CYLINDER of about twice the volume than the volume of each of the fired cylinders. The fired cylinder uses both fuel and steam for producing work output. It uses the heat of exhaust gases to generate steam from water which is further used as a working fluid for additional Power stroke. And hence both the fired cylinders work in a six stroke cycle. Furthermore the exhaust of both fired cylinders at every exhaust stroke is not rejected to atmosphere rather it is passed to LOW-PRESSURE cylinder where the additional expansion of exhaust products take place thereby giving extra power strokes. The above-described property of 3-cylinder engine causes the expansion ratio of medium in the engine is two times greater than the compression ratio. There is increased in Specific power and specific torque generated and also increased in fuel efficiency .It results in less fuel consumption. It uses the heat of exhaust gases which is usually lost in a engine. Around 30-40 % of energy is lost along the exhaust gases and 30-40 % is lost in cooling the engine. This 3-cylinder engine also reduce the heat use for cooling the system as water injected decrease the peak temperature of the cylinder walls.
Keywords: 3-cylinder engine, combined working, water injection, crankshaft and additional expansion.
