| Abstract: | New model cars are rolled out with advanced technology to reduce emission, fuel consumption, weight, noise and to
improve the stability of the vehicles. Engine performance is predicted based on cylinder diameter, stroke length, fuel supply,
combustion methods, speed and compression ratio. Designing of a new engine is based on experience about the existing
engine similarities and performances. In this work, a study was conducted on existing 50 4-cylinder petrol engine car models
in India. Information on engine bore, stroke length, cubic capacity, compression ratio, kerb weight, maximum brake power
and torque was collected from automobile related sources. Stroke length was observed increase and stroke to bore ratio
decrease with increasing bore of the engines. Maximum brake power and torque of engines are proportional to bore of
engines. BMEP, brake power per unit volume, brake power per unit piston area, brake power per unit weight tend to rise and
piston speed and weight per unit volume tend to decrease with increasing bore for the existing petrol car engines. The results
show similarity between existing car engines and give an idea to design new petrol car engines for best performances. |
