Abstract

本实用新型提供了一种不顶气门的活塞,所要解决的技术问题是:目前捷达汽车发动机上二阀活塞的顶部是一个圆池形燃烧室,该燃烧室的深度小于气门开启行程,所以在正时皮带断损时气门与活塞顶部相撞,导致气门杆弯曲损坏,本实用新型的要点是:在活塞顶部的燃烧室为两圆搭叠形,其深度大于气门开启的行程。本实用新型的积极效果是:在正时皮带断损时活塞顶部不撞击气门,可减少损失。它适合捷达汽车二阀发动机上使用。

Description

一种不顶气门的活塞
技术领域
本实用新型涉及汽车发动机上的活塞,特别是捷达汽车二阀电喷节能不顶气门的活塞。
背景技术
目前捷达汽车发动机上二阀活塞的顶部是一个圆池形燃烧室,该燃烧室的深度小于气门开启行程,所以在正时皮带断损时气门与活塞顶部相撞,导致气门杆弯曲损坏。
发明内容
针对现有技术的不足,本实用新型的目的在于提供一种可避免上述不足的捷达汽车二阀电喷节能不顶气门的活塞。
本实用新型的目的是这样实现的:它包括活塞体,其特征是:在活塞顶部的燃烧室为两圆搭叠形,其深度大于气门开启的行程,这样在正时皮带断损时活塞顶部不撞击气门。
本实用新型与现有技术方案相比,在正时皮带断损时活塞顶部不撞击气门,可减少损失。
附图说明
下面结合附图进一步说明本实用新型。
附图是本实用新型的结构示意图。
具体实施方式
它包括活塞体1,在活塞顶部的燃烧室2为两圆搭叠形,其深度为3.2mm,大于气门开启的行程,这样在正时皮带断损时活塞顶部不撞击气门。

Claims (2)

1、一种不顶气门的活塞,它包括活塞体,其特征是:在活塞顶部的燃烧室为两圆搭叠形,其深度大于气门开启的行程。
2、按照权利要求1所述的不顶气门的活塞,其特征是:所说燃烧室的深度为3.2mm。
