ABSTRACT:
In this heat insulating engine, an auxiliary combustion chamber which is formed by a block consisting of a material of a low heat transfer rate and provided on the inner surface thereof with a thin member composed of a high-density ceramic material, and which is provided with a fuel injection nozzle in the wall thereof, is communicated with a main combustion chamber fitted in a cylinder head via a heat insulating member and formed by a thin member consisting of a high-density ceramic material. Accordingly, the thermal capacity of the inner surface of the auxiliary combustion chamber becomes small, and the mixing of the atomized fuel with air is effected speedily. Consequently, the combustion temperature increases in a short period of time, and the generation of smoke is suppressed. The gaseous mixture is then blow out as a flame from the auxiliary combustion chamber into the main combustion to suddenly reduce the fuel equivalent ratio, so that the combustion temperature also lowers to supress the generation of NOx.
