In order to improve fuel consumption and eliminate the cooling system on a diesel engine having low fuel consumption, a low heat rejection (LHR) engine constructed with the thermos structure was studied. Since air temperature at the end of the compression stroke in a LHR engine are much higher than that of a water-cooled engine, the combustion of LHR engine deteriorated and the fuel consumption and exhaust emissions degraded. The combustion phenomenon in the LHR engine were observed. The reason of deterioration in combustion was insufficient air and fuel mixing. In order to improve the mixing, a new pre-combustion chamber was located in the center of the cylinder. Drilled connecting holes radiating to cylinder wall were developed. The desired characteristics at the LHR engine including fuel consumption and exhaust emissions was achieved in the LHR engine with the new precombustion chamber.
