Vehicle power system comprising an auxiliary engine in combination with the main vehicle engine
First Claim
1. In a vehicle having a main internal combustion engine for driving the vehicle and an electrical system and having a main liquid cooling system connected to the main engine and having fluid passage means for circulating liquid coolant of the cooling system through the engine block of the main engine, and with the vehicle having an operating compartment and further having a vehicle heating system selectively actuable for providing heat to the operating compartment from the main engine cooling system, the combination comprising an auxiliary internal combustion engine, an auxiliary liquid cooling system connected to said auxiliary engine and connected to said main liquid cooling system, heat transfer means selectively actuable for connecting the vehicle heating system to said auxiliary liquid cooling system for transferring the heat absorbed from said auxiliary engine to the vehicle compartment heating system, said heat transfer means being selectively actuable to a first condition to circulate the liquid coolant for the auxiliary cooling system to the compartment heating system and blocking flow from the auxiliary cooling system to the engine block via said fluid passage means, said heat transfer means being selectively actuable to a second condition to circulate the liquid coolant of the cooling system from said heat exchanger to the engine block via said fluid passage means.
