1. An air inlet system of an engine, comprising:
- a throttle;
a fan frame having a hole exposed toward outside of the air inlet system;
a fan connected to the throttle and mounted into the fan frame behind the hole;
a valve mounted to the hole;
a motor for driving the fan to force air into at least one intake manifold of the engine through the throttle and for driving the valve open, wherein the motor comprises an air intake device, an air input hole and an air output hole, and the air intake device is for forcing air into the motor through the air input hole and for exhausting air from the motor through the air output hole;
a throttle sensor for controlling a rotational speed of the fan, an amount of air passing through the air intake device and an opening of the valve which is opened by the motor according to a motion of a throttle pedal;
a mass airflow sensor for controlling the rotational speed of the fan, the amount of air passing through the air intake device and the opening of the valve according to an amount of air flow passing through the intake manifold of the engine; and
a temperature detect switch for controlling the rotational speed of the fan, the amount of air passing through the air intake device and the opening of the valve according to a temperature in the intake manifold of the engine.

Abstract
An air inlet system of an engine includes a throttle, a fan frame, a fan, a valve, a motor, and a throttle sensor. The fan frame has a hole exposed toward outside of the air inlet system. The fan is connected to the throttle and mounted into the fan frame behind the hole. The valve is mounted to the hole. The motor is for driving the fan to force air into at least one intake manifold of the engine through the throttle and is for driving the valve open. The throttle sensor is for controlling the rotational speed of the fan according to the motion of a throttle pedal.
