Abstract
Internal combustion engine of the liquid fuel injection and compression ignition type, which includes a combustion pocket into which at least a substantial proportion of the air charge is forced during each compression stroke through a passage of transfer, duct-like part or opening and having at least a part of the inner surfaces of the bag formed from one or more embossed pieces of heat-resistant thin sheet metal, the outer surfaces of which are spaced from adjacent surfaces Cooler engine by a small clearance to create a thin insulating space, over a wide area, that is exposed to compression and combustion gases.
