given:
Cylinder diameter D = 580 mm
Stroke length S = 640 mm
Indicated mean pressure pmi = 2.2 MPa
Effective average pressure pme = 2.0 MPa
Rotation frequency n = = 6.0 s ‐ 1
Fuel consumption (v / 80%) be = 195 g / kWh
The calorific value of the fuel hn = 42.7 MJ /

a) Maximum engine power (Pe) in kW.
b) Mechanical efficiency.
c) Effective thermal efficiency.
d) How much fuel must be supplied to the engine at 80%, 100%, 50%
and 25% load and constant speed?
(use the curve to find specific fuel consumption (SFOC) for the
different load cases. The curve shows increased
consumption in relation to the lowest value which is at approx. 80%
load)
