Dual Fuel Engines

Three distinct gas engine technologies Dual-Fuel (DF) engines Runs on gas with 1% diesel (gas mode) or alternatively on diesel (diesel mode) Combustion of gas and air mixture in Otto Cycle, triggered by pilot diesel injection (gas mode), or alternatively combustion of diesel and air in Diesel Cycle (diesel mode) Low pressure gas admission Gas Diesel (GD) engines Runs on various gas /diesel mixtures or alternatively on diesel Combustion of gas, diesel and air mixture in Diesel Cycle High pressure gas injection Spark ignition gas (SG) engines Runs only on gas Combustion of gas and air mixture in Otto cycle, spark plug ignition Low pressure gas admission

Gas Mode: Otto principle Low pressure gas admission Pilot diesel injection

Diesel mode: Diesel principle Diesel injection
