Patent ID: 10982629

Abstract:
An intake air filter box utilizing an intake air heater that inhibits the buildup of snow and ice within the intake air filter box, keeping the associated flow passages clear such that pressure loss is not adversely affected. This intake air heater can include an electric heater or a radiant heater coupled to the exhaust gas recirculation (EGR) system of the vehicle, or to another source of heated fluid. Preferably, the intake air heater is disposed on the “dirty” side of the filter disposed within the intake air filter box, adjacent to the intake air conduit and air intake of the vehicle. This is where the snow and ice accumulation occurs. A drain is provided in the bottom of the intake air filter box housing to allow the escape of water from the melted snow and ice, ensuring that this moisture is not delivered to the turbocharger and engine with the intake air.
