<P>PROBLEM TO BE SOLVED: To provide a gas accumulation method for an internal combustion engine capable of maintaining an oxygen concentration of compressed gas in an accumulated gas container within a proper concentration range by accurately measuring the oxygen concentration of the gas stored in the accumulated gas container and suppressing variation in exhaust gas performance by supplying gas with a proper oxygen concentration stored in the accumulated gas container when performing supercharge-assist in a cylinder of an engine from the accumulated gas container, in the internal combustion engine using the compressed gas accumulated in the accumulated gas container for the supercharge-assist, and to provide the internal combustion engine. <P>SOLUTION: In the control for adjusting an oxygen concentration Co in an accumulated gas container 27, a part Cp of gas C in the accumulated gas container 27 is led to a state closer to the atmospheric pressure in the measurement of the oxygen concentration Co of the gas C compressed in the accumulated gas container 27, and the oxygen concentration Coa of the gas Cp led to the state closer to the atmospheric pressure is measured. The measured value Coa is used as the measurement value Com of the oxygen concentration Co in the accumulated gas container 27. <P>COPYRIGHT: (C)2013,JPO&INPIT |
