The authors studied the tracer gas method which had already been suggested to be an applicable method of measuring the trapping efficiency of two stroke cycle engines. And in consequence, the superioritv in both accuracy and possibility of reappearance under the following conditions of measurement was found : The use of anhydrous monomethylamine as the tracer gas ; gas density being 0.1∼0.3% ; the use of 10 cc of 0.02 normal solution of sulfuric acid as the absorbing liquid ; the type of sampling tube being as shown in Fig. 12 (a) ; a mixture of bromcresol-green and methyl-red as the neutralization reagent ; gas sampling points in Fig.5 (a) and Fig.5 (b) and the gas sampling apparatus in Fig.8. Under these conditions, the errors were within the range of ±2%. The accuracy was compared with the results obtained by the gas sampling valve method.
