摘　　要：机械热量损失在热平衡中的占比并不大,但由于机械转换热量损失的重大发现,导致机械热量损失占比大幅突升,势必挤压原本占比很大的燃烧热量损失,进而使得不高的理论热效率得以大幅突破,甚至直逼拥有最高热效率的卡诺循环热效率,彻底撼动现有传统发动机的效率体系。然而,有效热效率并未因为理论热效率的大幅突破而受到丝毫影响,但如果深入探究燃烧热量损失和造成机械转换热量损失的固有缺陷,那么广为诟病的有效热效率也可逆势翻盘。The proportion of mechanical heat loss in the heat balance is not large. However, due to the major discovery of mechanical conversion heat loss, the proportion of mechanical heat loss has risen sharply. It is bound to squeeze the loss of combustion heat which originally accounts for a large proportion and thus make a great breakthrough in the low theoretical thermal efficiency. The thermal efficiency of Carnot cycle, which has the highest thermal efficiency, completely shakes the efficiency system of existing traditional engines. However, the effective thermal efficiency has not been affected by the breakthrough of theoretical thermal efficiency. However, if the inherent defects of combustion heat loss and mechanical conversion heat loss deeply explored, the widely criticized effective thermal efficiency can also be reversed.
