ABSTRACT:
Method and apparatus for starting a glow-plug assisted diesel engine at a subfreezing temperature involves directing a flow of concentrated oxygen at a predetermined rate and pressure to the intake manifold of the diesel engine. The concentrated oxygen flow is directed directly into the intake manifold to fill the intake manifold with a high concentration of oxygen. When drawn into the firing chamber of the engine, the high concentration of oxygen is compressed during the compression stroke of the engine. Fuel is injected into the chamber with the compressed oxygen and ignited to start the engine.
