However, with the lower load factor, engine speed is limited to the minimum speed run, part of the system for the heat is wasted, a lower utilization.
但随着负荷率的降低，发动机转速被限制在最小转速下运行，系统的一部分供热量被浪费，一次能利用率降低。

As a result, CPU can work simultaneously with the printer. Thus CPU can be fully utilized and the utilizationfactor of the system is heightened accordingly.
