北京牌492Q型发动机原设计使用216A16型双腔汽化器,这种汽化器系双腔开动式,常用于大排量多缸高速发动机上,用以保证各缸得到同样重量和浓度的混合气,提高各缸混合气质量的均匀性,减少抢气现象,从而提高发动机的动力性。故492Q型发动机的后备功率较大,越野性和牵引性能较好,且油耗也较高。设计最高马力75,油耗每百公里17升,载重量与同类型车相同
Beijing brand 492Q engine original design uses 216A16 dual-chamber carburetor, this carburetor is double-chamber start-type, commonly used in large displacement multi-cylinder high-speed engine, to ensure that each cylinder to get the same weight and concentration of the mixture, improve the Cylinder gas mixture of the quality of uniformity, reduce gas grab phenomenon, thereby enhancing the engine power. Therefore, the 492Q engine reserve power larger off-road and traction better, and fuel consumption is higher. Design maximum horsepower 75, fuel consumption of 17 liters per 100 kilometers, carrying the same weight as vehicles
