An "environment-protecting and combustion-supporting device", is mounted on the front end of the intake manifold of a car engine for providing air with a high content of oxygen, hydrogen molecules and high humidity. The device improves combustion efficiency of the engine and lowers intake temperature to reduce damage to the engine. Toxic substances such as carbon monoxide (CO) and hydrogenated carbon (HC) are reduced to improve air quality.
