Abstract
Abstract The invention involves a vehicle with a cab. The environment of the cab may be maintained by a heating, ventilation, and air-conditioning (HVAC) system that will provide cool air to the cab in hot weather and warm air to the cab in colder weather. The HVAC system will have its own specific air heating and cooling components. The HVAC has a supply to the cab for providing the cool or warm air depending on the need. A siphon or alternative point of distribution of the HVAC output may be a HVAC diversion line that leads into the inlet of the turbocharger or supercharger of the vehicle engine to mix with ambient air entering the turbocharger. In an alternative embodiment, a compressed air source may be bled into the turbocharger or supercharger inlet.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
137 words
A mobile vehicle, comprising: an engine with an engine inlet air compressor to compress incoming ambient air; said engine engaged to and for driving a drive shaft through a transmission and drive shaft rotation being imparted on driving wheels through a drive axle; said engine being contained within an under hood area of a chassis; a cab from which said vehicle is operated and said cab engaged to said chassis; an internal environment of said cab may be maintained by a heating, ventilation, and air-conditioning system; and said heating, ventilation, and air-conditioning system having a supply to said cab and a siphon from said heating, ventilation, and air-conditioning system output being a diversion line leading into an inlet of said engine inlet air compressor to mix with ambient air entering said engine inlet air compressor during operation.
Claim 2
Dependent Claim
