High compression ratio if choose low grades of gasoline engine, can make the cylinder temperature rises, the incomplete combustion of gasoline, strong vibration machine, so that the output power down, damage to the parts, fuel consumption and driving. If lower compression ratio engine with high grade oil, can appear "delay" phenomenon, namely the compression ratio is less than the highest point of spontaneous combustion, as will appear incomplete combustion phenomenon, the engine is no good.

Hicks's definition, though primarily for personal gain, applies to businesses as well. In the case of the enterprise, according to this definition, the enterprise income can be understood as the maximum amount that can be allocated in the enterprise cost accounting period under the same amount of capital at the end of the term and the beginning of the period.
