Abstract: A sensor cleaning system for a vehicle is disclosed. In particular, the sensor cleaning system has anti-freezing and defrosting functions. The sensor cleaning system includes: an air tank configured to store compressed air; a heating element disposed in the air tank and configured to apply heat to the air tank; and a controller configured to operate the heating element when a preset condition is satisfied.

Abstract: A sensor cleaning system has anti-freezing and thawing functions in an air-jet sensor cleaning system. The sensor cleaning system includes a distributor having a channel into which compressed air is introduced and having a plurality of exits. The distributor is configured to distribute the compressed air from the channel to each of the exits. A valve of the system is formed integrally with the distributor and is capable of being opened or closed to allow or prevent supply of the compressed air through each of the exits. A heating element of the system is configured to apply heat to the distributor and a controller is configured to operate the heating element when a preset condition is satisfied.

Abstract: An exhaust heat recovery apparatus is installed proximate an engine and at a front side of a warm-up catalytic converter in an exhaust system, where the exhaust system includes an exhaust line connected with the engine, and the warm-up catalytic converter is installed at the exhaust line. The exhaust heat recovery apparatus includes a bellows unit which is of a dual-pipe type and exchanges heat between exhaust gas emitted through the exhaust line and coolant circulating from a cooling system to the engine.
