IPC: F02B77/00
Filed: 2001-03-28
Abstract: PROBLEM TO BE SOLVED: To reduce the backlash rattle of gear train for transmitting power to a balancer, in an internal combustion engine provided with a balancer and having an aluminum alloy-made cylinder block. SOLUTION: The balance shaft 14 of a balancer is driven by a crankshaft 12 of an internal combustion engine 10 via a transmission mechanism of gear train, which consists of a crankshaft gear 26 combined with a crankshaft 12 and a balance shaft gear 28 combined with a balance shaft 14. The crank shaft gear 26 is made of aluminum alloy so that it may be equal to a cylinder block 18 in thermal expansion coefficient.
