Abstract

A cold start system is connected in an electrical circuit to a neutral start switch of a diesel powered vehicle. The electrical circuit includes a thermal switch and an electrical valve. The electrical valve is openable to permit communication between an ancillary fuel reservoir and the diesel engine manifold. The electrical valve opens only when the transmission is in neutral, the ancillary fuel switch is closed, and the thermal switch is not opened.
