Abstract: An intake enhancement system is arranged for incorporating with a vehicle which includes a combustion engine and a heat exchanger for generating a cooling effect. The intake enhancement system includes an intake cooling unit for delivering a combustion element to the combustion engine, wherein the intake cooling unit is thermally conducted with the heat exchanger for heat-exchanging the combustion element with heat exchanging agent of the heat exchanger so as to substantially cool down the combustion element along the intake cooling unit before the combustion element delivers to the combustion engine.

Abstract: An intake enhancement system for a vehicle includes a chiller bath, a delivery line operatively extended from the chiller bath for tapping at a heat exchanging line of a HVAC system to guide a heat exchanging agent flowing between the chiller bath and the HVAC system, and a cooling line operatively extended from the chiller bath for guiding a cooling agent to flow from the chiller bath toward the internal combustion engine. The chiller bath provides a heat-exchanging place for cooling the cooling agent by the heat exchanging agent. Therefore, the cooling agent is guide to cool the combustion element before the combustion element enters into the internal combustion engine for enhancing an efficiency of the internal combustion engine.
