国产492Q型发动机是我国60年代参考苏联伏尔加轿车发动机制造的产品。两种发动机的缸径和行程都是92×92mm。活塞、活塞销尺寸均差异不大。气门挺杆、推杆、摇臂和摇臂轴、气门弹簧等均可代用。两种机型的凸轮轴都是5道轴颈,其尺寸分别是(?)52、(?)51、(?)50、(?)49、(?)48mm,轴向游隙均在0.8～0.20mm之间,凸轮升程和配气相位角有差异,但并不影响将492Q型发动机的凸轮轴衬套用于伏尔加牌嘎斯24-10型发动机上。另 Domestic 492Q-type engine is the reference to the Soviet Union in the 60s Volga car engine manufacturing products. Both engine bore and stroke are 92 × 92mm. Piston, piston pin size difference is not big. Valve lifter, putter, rocker and rocker shaft, valve spring, etc. can be used instead. Both types of camshafts are 5-way journals with dimensions of (?) 52,? 51,? 50,? 49,? 48 mm and axial clearances of 0.8 ~ 0.20mm, there is a difference between the cam lift and the gas phase angle, but it does not affect the use of the 492Q camshaft bushing on the Volga GAS 24-10 engine. another
