美国陆军坦克—机动车辆司令部(TACOM)的研究、开发和工程中心与底特律柴油机公司(DDC)联合研制了一种改进的M109系列自行榴弹炮车用发动机。这种发动机设计成了一种“直接”替换式的动力装置,对车辆不需改动。外形与原M109系列自行榴弹炮车发动机(底特律公司生产的8V—71T8缸柴油机)相同,标定功率为302kW。结构上一是在缸盖上的排气道加装了用于热隔的不锈钢内套,废气从内套中通过,内套和排气道壁之间的气隙使其周围的缸盖材料与1000°F的废气热隔绝开来。可以
The Army Corps-TACOM Research, Development and Engineering Center, in collaboration with DDC, has developed an improved M109 Series self-propelled howitzer car engine. This engine has been designed as a “direct” replacement power unit without modification to the vehicle. Shape and the original M109 series of self-propelled howitzer engine (Detroit’s 8V-71T8 cylinder diesel engine) the same, the rated power of 302kW. The structure of the first one in the cylinder head of the exhaust channel installed for the thermal insulation of the stainless steel sleeve, the exhaust through the inner sleeve, the inner sleeve and the exhaust air gap between the wall so that the cylinder head material around it Exhaust heat at 1000 ° F. can
