A high-speed gas-sampling technique has been applied to reveal the time development of spatial distributions of several chemical species produced during combustion in the swirl and the main chambers. To enable traversed gas-sampling in each chamber, experiments have been made by using a double-scavenged two-stroke cycle engine with a simulated two-dimensional chamber configuration. By these experiments the following matters have been examined in detail; the extent of fuel-rich zones, their decay with time, the action of swirling air motion, the formation of nitric oxide, the formation of hydrocarbons and of carboneous substance, the state of the outflow of gas from the swirl chamber into the main chamber, and the flame spread within the main chamber. Besides, the influences of some operating conditions and of design parameters, such as overall fuel-air ratio, injection timing, dimension of connecting passage, and direction of the fuel spray, upon these items have been investigated.
