Description

燃用可燃气体的增压及增压中冷气体发动机
技术领域
本实用新型涉及一种增压中冷气体发动机。 
背景技术
现有的增压气体发动机，由于采用的是先增压后混合的进气方式，对燃气调压系统要求过高，在实际运用中往往难以实现，其动力性能不能充分发挥，升功率较低，难以覆盖更高的功率范围。 
发明内容
本实用新型的目的在于提供一种先混合后增压的进气方式，动力性能更好的燃用可燃气体的增压及增压中冷气体发动机。 
本实用新型的技术解决方案是： 
一种燃用可燃气体的增压及增压中冷气体发动机，包括进气管、排气管、气缸，其特征是：在排气管上装有增压器，在排气管出口到进气管之间装有空-空中冷器。
增压器包括压气机，压气机通过轴连接废气涡轮。压气机的进口连接燃气混合器。燃气混合器的进口连接空气滤清器。气缸缸径为135～140mm。 
本实用新型发动机动力性能好，且降低了对燃气调压系统的要求，在同样的气缸工作容积可容纳更多的新鲜充量，从而可多供给燃料，提高输出功率。 
附图说明
下面结合附图和实施例对本实用新型作进一步说明。 
图1是本实用新型一个实例的结构示意图。 
图2是图1的局部放大示意图。 
具体实施方式
一种燃用可燃气体的增压及增压中冷气体发动机，包括装有进气管1、排气管2、气缸3，在排气管2上装有增压器6，在排气管出口到进气管之间装有空-空中冷器4，增压器包括压气机5，压气机通过轴连接废气涡轮7，压气机的进口连接燃气混合器9，燃气混合器的进口连接空气滤清器10。 
本实用新型的原理是：当发动机运行时，排气管2中的排气能量带动废气涡轮7旋转，与废气涡轮同轴的压气机5叶轮同时旋转，空气滤清器10出来的空气进入混合器9与燃气进行混合，混合气再进入压气机5进行压缩，压缩后送往空-空中冷器4，混合气冷却后进入气缸3，这样混合气在进入气缸前得到压缩并冷却，从而使其密度增大，在同样的气缸工作容积下可容纳更多的新鲜充量，从而可多供给燃料，提高了输出功率。
