本文讨论美军坦克和机动车辆指挥部与寇明斯公司的绝热发动机研究计划的目标、进展情况和将来计划。绝热发动机的概念是,把柴油机的燃烧室用耐高温材料使它与外界隔绝,形成接近于绝热状态。从这种概念出发,在正常情况下将冷却和排气系统所损失的热能通过涡轮机转变成有用功,这就是绝热发动机能提高功率和改善效率的原因。通过发动机试验已反复证明绝热发动机是世界上燃油效率最高的发动机。有代表性的450HP、多缸发动机的最低比油耗为0.285磅/马力·小时(48％热效率)。一台早期的绝热发动机(安装在五吨军车上)已经顺利的完成了初步的车辆评定工作。下阶段有漫长研制周期的600～750HP 绝热发动机的设计和斡旋工作正在进行中,低摩擦绝热发动机方案的工作也在继续进行。
This article discusses the objectives, progress, and future plans for an adiabatic engine research program for the U.S. Army’s tank and motor vehicle headquarters and the company. The concept of an adiabatic engine is that the combustion chamber of a diesel engine is insulated from the outside with a refractory material, forming a state close to the adiabatic state. From this concept, the heat lost by the cooling and exhaust systems is converted to useful work by the turbine under normal conditions, which is why the adiabatic engine can increase power and improve efficiency. Engine tests have repeatedly proven that adiabatic engines are the most fuel-efficient engines in the world. The typical 450HP, multi-cylinder engine has a minimum fuel consumption of 0.285 lbs / hh (48% thermal efficiency). An early adiabatic engine (mounted on a five-ton military vehicle) has successfully completed its initial vehicle qualification. The design and good offices work of the 600-750HP adiabatic engine with a long development cycle at the next stage is under way and the work on low-friction adiabatic engine program is continuing.
