Abstract
An auxiliary intake device for an engine includes a bypass tube and a control valve mounted on the bypass tube. The bypass tube includes a first end connected to an air cleaner and a second end connected to an intake tube at a position between an intake manifold and a throttle that is mounted in an intake tube between the air cleaner and the intake manifold. The control valve is closed when a speed of an engine is below a predetermined value. The control valve is opened when the speed of the engine is equal to or greater than the predetermined value, allowing additional air from the air cleaner to enter the manifold via the bypass tube and the control valve. An air intake system for an engine with the auxiliary intake device is also provided.

An auxiliary intake device for an engine, comprising:
- a bypass tube including a first end adapted to be connected to an air cleaner and a second end adapted to be connected to an intake tube at a position between an intake manifold and a throttle that is mounted in an intake tube between the air cleaner and the intake manifold;
- and
- a control valve mounted on the bypass tube, the control valve being closed when a speed of an engine is below a predetermined value, the control valve being opened when the speed of the engine is equal to or greater than the predetermined value, allowing additional air from the air cleaner to enter the manifold via the bypass tube and the control valve.
