近年来,中、小排量的低梁车在经济不很发达的我国大部分地区及东南亚一带发展很快,而国内生产的该类型车多为二冲程发动机,存在油耗高、可靠性差等通病,不能满足人们的需要。因此中国嘉陵工业股份有限公司决定开发造型美观、配备90毫升四冲程发动机的低梁车,以满足广大用户的需要。 一、结构特点 1.发动机 该发动机活塞顶部设计不同于传统设计(凸形),该活塞顶部为凹形,它可使燃气产生紊流,具有燃气效率高、油耗低的特点;减速部分的传动比小,具有传递扭矩富余的特点,为今后发展系列产品(大功率发动机)创造了有利条件;另外还设置了限制车辆行驶中1挡挂空挡的安
In recent years, medium and small displacement low beam car in the less developed economy in most parts of China and Southeast Asia developed rapidly, while the domestic production of this type of car mostly two-stroke engine, there is high fuel consumption, poor reliability and other common diseases , Can not meet people’s needs. Therefore, China Jialing Industrial Co., Ltd. decided to develop beautiful, equipped with 90 milliliters of four-stroke engine beam beam car to meet the needs of users. First, the structural features 1. Engine The engine piston top design is different from the traditional design (convex), the top of the piston is concave, it can produce gas turbulence, with high gas efficiency, low fuel consumption characteristics; deceleration part of the transmission Than the small, with the characteristics of the transmission torque surplus for the future development of products (high-power engine) has created favorable conditions; also set a limit vehicle driving 1 block neutral gear security
