指示热效率是指发动机实际循环指示功与所消耗的燃料热量的比值。
对于较高负荷，存在一个指示热效率较高的甲醇浓度区间。
While at high loads, there exists a region of methanol concentrations for getting optimum thermal efficiency.
结果表明：HCCI燃烧有较高的指示热效率，最高可达60%；指示热效率主要受负荷的影响，转速对其几乎没有影响。
The experimental results show that HCCI can obtain high mean indicated heat efficiency up to 60% and mainly be effected by the engine load and hardly by the engine speed.
