ABSTRACT:
A standard diesel injection system and a mechanical direct-gas injection system are selectively operable, in combination with a continuous pilot injection system, to provide a combustion system that is capable of operating in either a conventional diesel mode or a dual-fuel mode. Operation between convention diesel or dual-fuel combustion modes is mechanically controlled by a two-position, four-way control valve. The mechanical direct-gas injection system is actuated by pulsed diesel fuel directed to the actuation chamber of a gas injector by the same injection pump used to provide diesel fuel to the combustion chamber during conventional diesel operation.
