Abstract

一种内燃机，涉及内燃机部件领域，包含水平对置活塞(1)、圆缺口曲柄(2)、曲轴(3)及水平对置缸体(4)，圆缺口曲柄(2)嵌套于水平对置活塞(1)的圆缺口曲柄孔(1-1)圆型孔内部，两个对置活塞头(1-3)均由活塞销(1-2)联接构成水平对置活塞(1)，圆缺口曲柄(2)的曲拐槽(2-2)通过曲拐(3-1)与曲轴(3)连接，整体嵌套于水平对置缸体(4)内。它吸取了转子发动机的偏心圆曲轴设计思路，可以减少曲轴的震动和摩擦，减小了内燃机的体积，提高了推重比，有利于提高内燃机的高性能和延长使用寿命。

Description

一种内燃机
技术领域
一种内燃机。
背景技术
目前，内燃机的活塞都是一个单独的个体活塞，由曲柄连接活塞和曲轴做运动，机械磨损相对较大，零部件相对较多，促使曲轴较长，体积相对较大，因此制造成本较高，零部件较多。
实用新型内容
本发明的目的是提供一种内燃机的水平对置活塞和圆缺口曲柄、曲轴和水平对置缸体，它能实现内燃机的体积减小、轻量化和高性能。
为了解决背景技术所存在的问题，本发明是采用以下技术方案：它包含水平对置活塞1、圆缺口曲柄2、曲轴3和水平对置缸体4，圆缺口曲柄2嵌套于水平对置活塞1的圆缺口曲柄孔1-1圆形内部，圆缺口曲柄2的缺口曲拐槽2-2通过曲拐3-1与曲轴3连接。
所述圆缺口曲柄2的一半有离心平衡重2-1，水平对置活塞1上有两个活塞销1-2和两个活塞头1-3。
本发明吸取了转子发动机的偏心圆曲轴设计思路，可以减少曲轴的震动和摩擦，减小了内燃机的体积，提高了推重比，有利于提高内燃机的性能和延长使用寿命。
附图说明
图1为本发明的水平对置活塞结构示意图。
图2为本发明的圆缺口曲柄的结构示意图。
图3为本发明的曲轴结构示意图。
图4为本发明的水平缸体结构示意图。
具体实施方式
参照图1-图4，本具体实施方式采用以下技术方案：它包含水平对置活塞1、圆缺口曲柄2、曲轴3和水平对置缸体4，圆缺口曲柄2嵌套于水平对置活塞1的圆缺口曲柄孔1-1圆形内部，圆缺口曲柄2的缺口曲拐槽2-2通过曲拐3-1与曲轴3连接。
所述圆缺口曲柄2的一半有离心平衡重2-1，水平对置活塞1上有两个活塞销1-2和两个活塞头1-3。
所述圆缺口曲柄2的缺口用于连接曲轴3做滑动和旋转运动，同时水平对置活塞1做对置直线运动，曲轴3做圆周运动。
所述圆缺口曲柄2的直径可以大于或等于或小于活塞头1-3的直径。
所述圆缺口曲柄2起到连接水平对置活塞头1和曲轴3的作用，且圆缺口曲柄2的质量配重是一半圆的质量大于另一半圆的质量。
所述水平对置活塞1可以串联在一根曲轴3上形成多个对置活塞的内燃机。
本具体实施方式吸取了转子发动机的偏心圆曲轴设计思路，可以减少曲轴的震动和摩擦，减小了内燃机的体积，提高了推重比，有利于提高内燃机的性能和延长使用寿命。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述使用方法的限制，上述使用方法和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
