Abstract:
An apparatus for starting an internal combustion engine having a plurality of cylinders with pistons moving through a path of revolution therein, comprising:means for identifying the one piston in the plurality of pistons which is past a top dead center position of revolution in the internal combustion engine at the beginning of starting of the engine, wherein the next piston in the firing order from the one piston is positioned before its top dead center position;means for injecting compressed air into the cylinder of said one piston, forcing the piston to move sufficiently along its path of revolution that the next piston in the firing order comes to past a top dead center position;ignition for means for igniting the fuel/air combination in the cylinder of said one piston; andmeans for injecting fuel into the cylinder, following the one piston, which is on its intake stroke, wherein the injection of compressed air, the operation of the ignition means, and the operation of the fuel injection means occur substantially simultaneously, and wherein said compressed air injection means and said ignition means operate on successive cylinders in the firing order of the engine following said one piston and wherein said fuel injection means operates on successive cylinders in the firing order, following the one piston, which are on the intake stroke, until the engine starts.
