1 Engine Speed
low engine speed, or the number related to the engine per unit time for power frequency and magnitude of the active power, i.e., the effective power of the engine varies with the speed difference. Thus, the engine output in the description of the size, must also indicate its corresponding rotational speed. Predetermined product label on the engine speed and the corresponding effective power calibration are called calibration speed and power. Calibration conditions referred to in the engine operating condition at rated power and rated speed. The maximum engine power is not power calibration can be issued, it is valid to use maximum power limit based on engine use have been made. The same type of engine, its use is not the same as its rated power value is not the same. Effective torque also varies with engine operating conditions. Accordingly, the automobile engine and its torque corresponding to the maximum rotational speed can be output as an evaluation indicator of engine power.
