The concentration of CO_2,C_mH_n, O_2,CO, H_2,and CH_4 in gases collected through the sampling valve attached to the pre-chamber of the compression ignition engine, has been measured. The hydraulic pressure wave controls the sampling valve. The volume of gases in sampling tube is 300 cc at the atmospheric pressure and temperature which are collected at each crank angle ranging over about 1000 cycles. The running conditions are as follows, excess air factor is 1.9,specific fuel comsumption, 220 g/〓/h, power, 3.3 〓 at 500 rpm. There is a period after ignition during which CO and H_2 are more than CO_2,nevertheless O_2 concentration is twice as much as them. These gases have not completed burning, but may jet into the main chamber. Besides, we can see the probability of water gas reaction equilibrium in the pre-chamber. In next duration CO comes to be much less than CO_2.
