Abstract: The invention prevents reverse rotation of a diesel engine which is possible to occur when the engine is started. A camshaft 13 is driven by a crankshaft 5 through power transmission means, and cams 14, 21 and 22 are provided on camshaft 13 so as to drive a fuel injection pump 12, an intake valve and an exhaust valve, respectively. In fuel injection pump cam 14, middle stage portion 53 is radially larger than minimum radius portion 51 and is disposed at a predetermined angle R3 on the back side in the rotation direction of the fuel injection pump cam from maximum radius portion 52.

Abstract: A diesel engine 1 of the present invention comprises: a camshaft 13 with a cam 21; a fuel injection pump 12 having a plunger 84; a tappet for driving the plunger 84; and a slide portion 2b. The tappet includes a roller 80 and a roller tappet 82. The roller 80 serves as a rotor which abuts against the cam 21 so as to drive the fuel injection pump 12, and a roller tappet 82 serves as a support portion for supporting the rotor. The slide portion 2b slidably fits to the support portion. The roller tappet 82 has a tappet guide serving as a projection for restriction of rotation, and the slide portion 2b has a guide groove 92 into which the projection is fitted. Therefore, the rotor and the cam abutting against the rotor can be prevented from abrasion so as to maintain high accuracy in controlling slide stroke of the plunger.
