Diesel engine


A diesel engine with direct fuel injection has a cylinder bore with a diameter of less than 100 mm. A piston head has a recess with a diameter of less than half the diameter of the cylinder bore. At the piston top dead centre, the recess together with a cylinder head forms a combustion chamber. A spiral inlet duct creates a swirling movement of air in the cylinder bore with a swirl ratio of 1.0 to @. Two diametrically opposing fuel injection nozzles are provided. Each fuel injection nozzle opens at a tangent to the combustion chamber and produces a jet of fuel with the same direction as that of the air swirl.
