FUEL INJECTION METHOD FOR DIESEL ENGINE AND DIESEL ENGINE

摘要

A diesel engine (1) injects fuel into a combustion chamber (6) from a fuel injection valve (5) to generate sprays (7) in the combustion chamber (6). The axis L1 of the fuel injection valve (5) is offset outward in the radial direction of the cylinder (2) relative to the axis L2 of a cylinder (2). This positions the fuel injection valve (5) at a place on the inner peripheral surface side of the cylinder (2). Further, nozzle holes (5a) of the fuel injection valve (5) are divided into two groups located at the left and right of a straight line formed by interconnecting, in a plan view, the axes L1, L2. Also, the sprays (7) of fuel injected from the nozzle holes (5a) advance in a fan shape in the plan view and, on the side away from the fuel injection valve (5), collide with the inner peripheral surface of the cylinder (2).
