In an internal combustion engine 20 that promotes combustion of fuel injected from an injector 50 to a combustion chamber 21 by way of electromagnetic wave plasma, a plurality of pieces of the electromagnetic wave plasma are generated respectively for a pl...

In an plasma generation device 30 that generates electromagnetic wave plasma by emitting electromagnetic waves to a combustion chamber 21 of an internal combustion engine 20, combustion is promoted by increasing the amount of gas to be brought into contact...

While an "injection time representative crank angle", which is a timing for obtaining a "representative swirl velocity" according to an operation state of an engine is specified, a "spray representative position", which is a specified position in spray for...

The engine has two types of differently charged injection nozzles (1,2), and double intake valves with counter flow action. The fuel volume to be injected is distributed in a symmetrical or asymetrical ratio over the injection nozzles, dependent upon RPM r...
