Abstract

本实用新型涉及一种内燃机部件新型活塞,该活塞的燃烧室顶部边缘向内凹陷,其轴向剖面呈C型。该活塞压缩比小,可用于天然气电动机中,有效的防止了爆震。

Description

一种新型活塞
技术领域
本实用新型涉及一种内燃机部件,特别涉及一种新型活塞。
背景技术
目前,应用在柴油发动机中的活塞压缩比大,燃烧室轴向剖面呈W型或U型,该结构不适合燃烧天然气的发动机,且其活塞容易发生爆震,不易点燃。
发明内容
本实用新型的目的是提供一种结构设计合理、适于安装在天然气发动机的一种新型活塞。
为实现上述目的,本实用新型通过以下技术方案实现:
一种新型活塞,该活塞的燃烧室顶部边缘向内凹陷,其轴向剖面呈C型。
与现有技术相比,本实用新型的有益效果是:机构设计合理,有效的防止了爆震,活塞压缩比较小。
附图说明
图1是本实用新型主视图;
图2是本实用新型左视图。
图中:1-燃烧室
具体实施方式
见图1、图2,一种新型活塞,该活塞的燃烧室1顶部边缘向内凹陷,其轴向剖面呈C型。改进后的活塞,压缩比降低,有效的防止了爆震,适于在天然气发动机中使用。
