Q7: An automobile has a 3-liter SI V6 engine that operates on a 4-stroke cycle at 3600 rpm and produces a brake output torque of 205 N.m. The engine is squared and its compression ratio equals 9.5. At this speed air enters the cylinders at 85 kPa and 60°C, air-fuel ratio equals 15, and the mechanical efficiency of the engine is 85%. Take the heating value of fuel equals to 44 MJ/kg. Calculate: bore, stroke, mean piston speed, clearance volume per cylinder, brake power, indicated power, bmep, imep, bsfc, indicated thermal efficiency, brake thermal efficiency and the volumetric efficiency.

IC engines

The term "engine" indicates a mechanical device/machine used to convert input energy to a specific mechanical output. The input energy may be in the form of chemical energy, thermal energy, or so on and mechanical output is in the form of mechanical energy (work done). Generally, the engines classify into two groups which are internal combustion type and external combustion type, and further, these two types can be classified into two types that are reciprocating and rotary engines.
