Estimating the term…
A homogeneous charge compression ignition internal combustion engine capable of reliably reducing flame noise at a time of high-load operation is provided. The engine includes an injector 12a which injects a liquid hydrocarbon fuel to an intake port 23, and an injector 12b which directly injects an alcohol fuel into a combustion chamber 21. The liquid hydrocarbon fuel is distributed to an outer peripheral side of the combustion chamber 21, and the alcohol fuel is distributed to a central portion. The engine includes intake valves 25a and 25b, and divides an intake stroke into a period in which the intake valve 25a is stopped and a fuel-gas mixture is flown, and a period in which the intake valves 25a and 25b are operated and the flow is suppressed, guides the liquid hydrocarbon fuel into the combustion chamber 21 during the flow period, and injects the alcohol fuel to the combustion chamber 21 during the flow suppression period. The engine includes separating means for mixing water into a composite fuel of the liquid hydrocarbon and alcohol and separating it into an alcohol-water mixture solution and the liquid hydrocarbon, supplying means 6 for supplying the liquid hydrocarbon to the injector 12a, and supplying means 9 for supplying the alcohol-water mixture solution to the injector 12b.
A homogeneous charge compression ignition internal combustion engine comprising an intake port guiding a gaseous mixture into a combustion chamber, a first injector injecting a first fuel to the intake port, and a second injector directly injecting a second fuel into the combustion chamber, the engine compresses a fuel-gas mixture including the fuels supplied from both of the injectors to cause the same to self-ignite,
