一、问题的提出解放牌CA-10B型发动机经过技术改造成为CA-10C型发动机,其动力性和经济性均有显著提高。功率达到110PS,最低比油耗由255g/PS·h下降到245g/PS·h。但是,在综合路面运行条件下,与原CA-10B发动机比较,相对节油率并不十分理想。尤其是不带拖挂的单车对进一步提高经济的要求更为迫切。这样,就提出了一个新的课题——如何进一步改善解放CA-10C的经济性以适应生产需要,巩固和发展技术改造的成果。
First, the issue put forward Jiefang card CA-10B-type engine through the technical transformation into a CA-10C-type engine, its power and economy have significantly increased. Power reached 110PS, the minimum fuel consumption from 255g / PS · h down to 245g / PS · h. However, compared with the original CA-10B engine, the relative fuel efficiency is not very satisfactory under the conditions of comprehensive road surface operation. In particular, the bicycle without towing is more pressing for further economic growth. In this way, a new topic is raised - how to further improve the economy of CA-10C to meet production needs and to consolidate and develop the results of technological transformation.
