HYDROGEN INJECTION TWO-FUEL INTERNAL COMBUSTION ENGINE AND METHOD FOR OPERATING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen injection two-fuel internal combustion engine achieving perfect combustion through whole area of combustion chamber and suppressing creation of soot by connecting hydrogen injection from a hydrogen injection valve to the combustion chamber and liquid fuel injection from a liquid fuel injection valve and improving combustion conditions in adjacent of the liquid fuel injection valve where soot is easily created. SOLUTION: In the two-fuel internal combustion engine provided with the liquid fuel injection valve injecting liquid fuel in the combustion chamber of the engine (internal combustion engine) and a hydrogen injection valve injecting hydrogen in the combustion chamber, hydrogen injection timing and injection quantity from the hydrogen injection valve are controlled in connection with liquid fuel injection timing and injection quantity from the liquid fuel injection valve to set injection start timing of hydrogen from the hydrogen injection valve in a first half of a compression stroke of the engine and injection start timing of hydrogen from the hydrogen injection valve is controlled to before injection start timing of liquid fuel from the liquid fuel injection valve.
