DUAL FUEL ENGINE AND METHOD OF OPERATING THE SAME

In a dual fuel engine that is operated on main liquid fuel and gas fuel, a test injector (390) is used to inject test liquid fuel in a gas mode. An intake compression ratio is relatively low so as to avoid knocking in the gas mode. In a case where, for example, a heavy fuel oil is used as the main l...

Zusammenfassung:In a dual fuel engine that is operated on main liquid fuel and gas fuel, a test injector (390) is used to inject test liquid fuel in a gas mode. An intake compression ratio is relatively low so as to avoid knocking in the gas mode. In a case where, for example, a heavy fuel oil is used as the main liquid fuel, the test injector (390) is used so as to allow injection of test liquid fuel such as diesel in a liquid fuel mode prior to main liquid fuel injection so that main liquid fuel combustion can be facilitated at a relatively low compression ratio.
