An 14, 4-stroke diesel engine with 9 cm bore and 11 cm stroke running at a steady speed of 2200 RPM produces 90 kW of brake power. The compression ratio is 18:1, and mechanical efficiency 80%. Calculate:
a) Engine displacement in liters and average piston speed in m/sec.
b) The clearance volume for one cylinder in m³
c) Brake mean effective pressure in kPa
d) Torque in Nm
e) Indicated and friction power in kW
