(54) | Attachment structure for engine fuel pump |
(57) A cast rear case (6) is provided on a front of an engine, and defines, with a front
cover (7), a housing space for a timing chain mechanism. The rear case (6) includes
an extension (11) extending outwardly in a sideways direction of the engine. A pump
attachment portion (12) is formed on a surface of the extension (11) at a rear of
the engine. A supply pump (4) is fastened to the pump attachment portion (12) by a
bolt so that the supply pump (4) is driven by a crankshaft via chains of the timing
chain mechanism. This provides secure support of the fuel pump (4) to be driven by
a rotational force of the engine as a power source, without use of a dedicated bracket,
and without lowering latitude in layout of other devices or accessories attached to
a side of the engine.
