Development of balance shaft and flywheel for single cylinder diesel engine based on analytical approach and comparison with the simulation result

Vibration is a key factor of abrasion and destruction in the internal combustion engine. In internal combustion engines, the main causes of vibration is combustion pressure, connecting rod weight, piston weight and inertial forces. This vibration create corrosion and fracture in main part of engine such as crankshaft, camshaft and cylinder block in long time. This corrosion and fracture is effective on engine performance. Therefore is trying reduce or remove this vibrations for better engine performance. In multi cylinder engine, Counterweights are fitted on the crankshaft to eliminate the unbalance of forces and moments. In single and three-cylinder engines, the effects of inertia forces and moments cannot be completely eliminated using by counterweights. So balancer shaft is used to completely remove these effects. For the first time, the balancing shaft and flywheel is design with analytic equation and compare with result of simulation for one-cylinder diesel engine. (B112 of KIASA Company)
