Embodiment Construction

[0023] Embodiments of the present invention will be described below with reference to the drawings.

[0024] Such as figure 1 and figure 2 As shown, the engine 1 according to the present embodiment is an inline four-cylinder (first cylinder #1 to fourth cylinder #4) mounted horizontally in the engine room 100 at the front of the vehicle so that the cylinder bank direction faces the vehicle width direction. ) diesel engine (FF vehicle). Although not shown, the engine 1 employs a well-known structure including pistons, injectors (fuel injection valves), intake ports, exhaust ports, intake valves, exhaust valves, and the like inside and outside the cylinders.

[0025] Such as figure 1 As shown, the engine 1 has an engine main body 10 having a first cylinder #1 to a fourth cylinder #4 arranged in a row. Such as image 3 and Figure 4 As shown, the engine main body 10 includes a cylinder head cover 11, a cylinder head 12, a cylinder block 13, a lower cylinder block 14, and a...

Abstract

Provided is an accessory mounting structure for an engine that includes an engine body and a transmission which is disposed on one end of the engine body in the cylinder bank direction, and to which the output of the engine body is transmitted via a crank shaft provided to the engine body. When the output side, with respect to the transmission, of the crank shaft in the cylinder bank direction isdefined as the rear side, and the opposite side is defined as the front side, a fuel pump for pressure feeding fuel to an injector and a starter for causing the crankshaft to rotate when the engine isstarted are provided to the rear side end-part of a side surface of the engine body to which an intake manifold is mounted. When the engine is viewed from the cylinder bank direction, the starter projects farther outward than the fuel pump in an engine width direction which is perpendicular to the cylinder bank direction.

Description

technical field [0001] The present invention relates to an attachment structure of an engine of an automobile or the like. More specifically, it relates to an accessory mounting structure of an engine provided with a fuel pump that sends fuel pressure to an injector. Background technique [0002] In an automobile or the like, the engine is sometimes mounted horizontally in an engine room at the front of the vehicle so that the cylinder bank direction faces the vehicle width direction. Such an engine is mounted in an engine compartment such that the intake side of the engine body including the cylinder block faces the vehicle front and the exhaust side faces the vehicle rear. As a result, it is possible to suppress a drop in exhaust gas temperature due to traveling wind, and to achieve early activation and maintenance of activation of the exhaust purification device. [0003] In this case, in an engine that injects fuel directly into the combustion chamber such as a diesel ...
