 note = {In a small direct injection diesel engine, the effects of combustion chamber insulation on engine performance (fuel consumption, nitric oxide, unburned HC and exhaust smoke) were investigated by changing the combustion chamber materials, by inserting the teflon sheet and the air gap between the piston body and the piston crown. It was found that, by increasing the insulation the HC concentration decreases about 15% at light and medium load but the NO level increase a little, and that the smoke and the fuel economy become worse at heavy load., application/pdf},
