Maximizing volumetric efficiency of a diesel engine using an air pump to compress air-biogas mixture into the engine via venturi
This paper presents the effect of using a modified air pump to compress the mixture of air and biogas into a single cylinder diesel engine. The crankshafts of both were modified such that two equal size sprockets could be fastened to them. A toothed belt was used to synchronize the crank positions of the pump and diesel engine. By adjusting the angular positions of the crankshaft of the pump at 205 degrees in advance compared to the angular positions of the crankshaft of the diesel engine, the maximum volumetric efficiency of 99.95％ could be achieved at 1200 rpm. And when supplementing diesel fuel with biogas via the large venturi, the consumption of 50 cc. of diesel extended to 194.18％ at 1200 rpm as compared to running the engine with 50 cc. of diesel alone.
