Abstract
The present invention provides an internal combustion engine which can produce several types of fuels from a single fuel as needed. The internal combustion engine comprises reforming means 3 for reforming a first fuel to be used in homogeneous charge compression ignition combustion into a second fuel having high ignitability, by making the first fuel contact with a catalyst formed from N-hydroxyphthalimide. The engine uses the second fuel when conducting diesel combustion. The engine can switch between the homogeneous charge compression ignition combustion with the use of the first fuel and the diesel combustion with the use of the second fuel. The engine conducts the homogeneous charge compression ignition combustion when a load is low, and conducts the diesel combustion when the load is high. The internal combustion engine further comprises a first fuel injector 4b which injects the first fuel to an air intake port when the homogeneous charge compression ignition combustion is conducted, and a second fuel injector 4a which directly injects the second fuel to a combustion chamber when the diesel combustion is conducted. The engine further comprises fuel injection timing control me…
