Abstract:
A large primary engine is maintained in readiness to start under low ambient temperature conditions by a small auxiliary engine having a liquid cooling system in parallel with the cooling system of the primary engine. Exhaust from the auxiliary engine heats the coolant circulating through the two engines in a heat exchanger. The lubricating oil from the primary engine is also heated by the auxiliary engine exhaust in the same heat exchanger. A generator driven by the auxiliary engine charges the batteries used to start the primary engine.
