<p>Provided is an engine which can reduce black smoke by reducing fuel injection quantity when the engine enters acceleration state. An engine (100) comprises an engine speed sensor (44), a clutch operation detection means (42) which switches a clutch mechanism (23), an accelerator operation detection means (41) which determines a set engine speed (Nset), a fuel injection pump (21) which can change the injection timing according to the operation state, and a controller (20) which can control the injection timing automatically, wherein the controller (20) decides whether the engine entered acceleration state or not from the set engine speed (Nset) which is set by an accelerator and the current actual engine speed (Ne), and performs lead angle control for leading the angle of injection timing when the engine enters acceleration state.</p> |
