Abstract

一种卧式柴油发动机，包括一缸两活塞，工作期间使左缸提前工作7cm距离，两缸同时压缩到理想工作压力，瞬间将混合气体空间向左推移7cm后燃爆，燃爆后空间缩小17cm，爆发力增强，右缸仅提供原1/2燃料就可以实现原一缸的功效，活塞顶面为半圆形，该发动机可以节能25%〜30%。

Description

一种卧式柴油发动机 新式柴油发动机 （卧式） 立意新颖， 设计独特， 全新理念， 大 胆打破一缸一活塞传统成旧理论，挑战性提出一缸两活塞卧式工作行 程程序理念。其显著特征是缩小燃爆后的空间，使单位面积压强猛增， 一瞬间爆发力骤增， 推力强大， 外加配置新型活塞， 可使功率提高
25%〜30%， 节约油料 25%〜30%， 达到了节能降耗的目的 （市面上单 缸柴油机皆为卧式， 不存在磨损、 润滑等问题)。
技术领域
新型柴油发动机（卧式）属卡车制造工业领域， 发动机缸体活塞 部分。
背景技术
柴油机发动机经漫长时间的发展研究， 目前各项技术趋于成熟， 基本稳定， 但是科技发展无止境的， 暂且存在耗油高的弊端， 一缸一 活塞理论延用几百年未变， 一直未能突破， 有待超越。
发明内容
大胆将老式一缸一活塞立式发动机改一缸两活塞卧式，且使用新 型活塞， 并新颖的提出缩小爆燃后的空间， 大胆设想将左缸提前工作 行程 7cm的距离， 到自己的上止点， 此时两缸工作将燃烧室空气压 缩到理想的工作压力，在爆燃一瞬间，也就是爆燃零界点，左缸下行， 右缸继续上行跟近， 到自己的上止点后爆燃。这样人为的有意将压縮 好的混合气向左快速推移 7cm后瞬间燃爆， 此时左缸行程人为缩小 7cm, 加上原老式两个缸预留的压缩空间 8-lOcm距离， 实际缩小燃 爆后空间 17cm。 这样新式发动机活塞行程短， 瞬间爆发力强劲， 活 塞接近下止点时， 后续推力不减弱。 老式发动机活塞行程距离较长， 接近下止点时推力减弱。 以上距离都可以人为在发动机底盘调控。这 样外加新型活塞的配置起到了节能降耗的目的， 可节油 25%-30%， 在油料配置上， 左缸油料不变， 右缸油料可调为 1/2以下。 混合气空 间在原一缸的基础上增 1/2。 活塞上下止点及压缩空间， 燃爆后空间 油料量都可以发动机底盘齿轮调控。
