Abstract
A fuel injected internal combustion engine and a method of operating same, the engine having a fuel injection system wherein fuel is injected through a selectively openable injector nozzle directly into a combustion chamber of the engine by gas from a pressurized gas supply system. While the engine is being cranked during start-up of the engine, the injectory nozzle is opened to communicate said combustion chamber with the gas supply system. Gas compressed within the combustion chamber enters into the gas supply system to assist in rapidly establishing gas pressure for subsequent operation of the fuel injection system.
