Abstract:
This article presents a comparative study between two camshafts systems adapted
to the single cylinder engine of a Supermileage vehicle in a fuel economy
perspective. One system is from a Honda AF70E engine and the other is a new
design. The new camshaft system was improved for fuel economy by developing a
new camshaft that enhances volumetric efficiency while reducing friction losses.
The comparison was made by measuring the efficiency of the engine in the speed
range where the engine was used by the Supermileage vehicle and a calculation
was made to show which configuration is best for the vehicle.
