Title: Oxygen-injection-type internal combustion engine
Inventor: KITAMURA SHUICHI
IPC: F02D41/34
Filed: 2008-02-26
Abstract: <P>PROBLEM TO BE SOLVED: To improve thermal efficiency of an internal combustion engine by removing pump loss and irregular combustion, and render NOx in an exhaust gas free from being generated and further extend a driving region of thermally-high-efficiency pre-mixed compression ignited combustion.  <P>SOLUTION: The oxygen-injection-type internal combustion engine is equipped with an oxygen supplying container 15 in a two-cycle engine, an oxygen injection valve 29 for emitting a jet of oxygen from the oxygen supplying container 15 and a fuel injection valve 28 for emitting a jet of fuel, and an exhaust valve 22 for exhausting a combusted gas inside a cylinder. The jet of the fuel is once again emitted at an appropriate period subsequent to the first injection from the fuel injection valve 28 to form an ignitable and combustible gas mixture at the periphery of an ignition plug 27. Thus, pre-mixed compression ignited combustion is provoked by spark-ignited combustion caused by the ignition plug 27. Besides, a closing period of the exhaust valve 22 is allowed to vary by a variably valve operating device 4 depending on a driving state of an engine, making an actual compression ratio variable.  <P>COPYRIGHT: (C)2009,JPO&INPIT
