Abstract
Crankshaft offsetting to the thrust side causes a decrease in piston side force hence piston friction in the expansion stroke. However an increase in piston side force in the compression stroke was estimated by crankshaft offsetting for a diesel engine. Furthermore it was also estimated that crankshaft offsetting reduced efficiency of conversion from combustion pressure to engine torque. The effect of crankshaft offsetting on piston friction force and the conversion efficiency was investigated for a diesel engine. It was shown that piston friction force was improved but the conversion efficiency was significantly decreased by crankshaft offsetting to the thrust side.
