Abstract
Past methods for starting an engine have included increasing the amount of fuel to support combustion creating an excess of unburned fuel in the exhaust causing white smoke. Such past methods for starting an engine additionally required additional components, such as heater, and required an excessive draw on the battery to provide extensive glow plug operation and extensive cranking. The present method of starting an engine reduces and essentially eliminates white smoke, reduces the need for extensive glow plug operation and reduces the need for extensive cranking. The method of starting an engine includes the steps of: positioning an intake valve in a closed position; positioning an exhaust valve in a closed position; rotating a piston to a top dead center position; rotating the piston from the top dead center position toward a bottom dead center position; and injecting a fuel into the cylinder.
