Abstract
Abstract There is provided a multi-cylinder engine having an intake manifold that includes a plurality of induction pipes which are each connected at, one end thereof, to a cylinder head the induction pipes extending away from the cylinder head and being curved to extend along a side of a cylinder block, and thereafter being curved further to approach the cylinder block to finally extend toward the respective one end sides of the induction pipes. In the multi-cylinder engine, a starter motor is disposed in a gap defined between the intake manifold and the cylinder block.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
137 words
A multi-cylinder engine comprising: a cylinder block; a cylinder head mounted on said cylinder block; an intake manifold comprising a plurality of induction pipes, each of said induction pipes being connected at one end thereof to said cylinder head, said induction pipes extending substantially coextensively away from said cylinder head and being curved to extend along aisle of said cylinder block and being further curved inwardly toward said cylinder block, and finally extending generally parallel to said side of the cylinder block back toward one end of the respective pipe ends to define a substantially closed annular induction pipe arrangement laterally spaced from said side of said cylinder block; and at least one auxiliary engine part being mounted on the cylinder block and disposed in a gap disposed between said induction pipe arrangement and said cylinder block.
Claim 2
Dependent Claim
137 words
A multi-cylinder engine comprising: a cylinder block; a cylinder head mounted on said cylinder block; an intake manifold comprising a plurality of induction pipes, each of said induction pipes being connected at one end thereof to said cylinder head, said induction pipes extending substantially coextensively away from said cylinder head and being curved to extend along aisle of said cylinder block and being further curved inwardly toward said cylinder block, and finally extending generally parallel to said side of the cylinder block back toward one end of the respective pipe ends to define a substantially closed annular induction pipe arrangement laterally spaced from said side of said cylinder block; and at least one auxiliary engine part being mounted on the cylinder block and disposed in a gap disposed between said induction pipe arrangement and said cylinder block.
Claim 3
Dependent Claim
59 words
The multi-cylinder engine as set forth in claim 1 , further comprising: an electric device for said engine, said electric device being located adjacent to said intake manifold, wherein an electrode terminal of said electric device is disposed at a location which confronts an end face of said intake manifold in a direction in which said cylinders are arranged.
Claim 4
Dependent Claim

Claim 5
Dependent Claim
141 words
The multi-cylinder engine comprising: a cylinder block; a cylinder head mounted on said cylinder block; an intake manifold comprising a plurality of induction pipes, each of said induction pipes being connected at one end thereof to said cylinder head, said induction pipes extending away from said cylinder head and being curved to extend along a side of said cylinder block and being further curved inwardly to approach said cylinder block, and finally extending back toward a side of an associated one end; and at least one auxiliary engine part being mounted on the cylinder block and disposed in a gap defined between said induction pipes of said intake manifold and said cylinder block, wherein said at least one auxiliary engine comprises a starter motor including a plurality of magnet switches received in said gap and arranged in parallel with each other.
Claim 6
Dependent Claim
141 words
The multi-cylinder engine comprising: a cylinder block; a cylinder head mounted on said cylinder block; an intake manifold comprising a plurality of induction pipes, each of said induction pipes being connected at one end thereof to said cylinder head, said induction pipes extending away from said cylinder head and being curved to extend along a side of said cylinder block and being further curved inwardly to approach said cylinder block, and finally extending back toward a side of an associated one end; and at least one auxiliary engine part being mounted on the cylinder block and disposed in a gap defined between said induction pipes of said intake manifold and said cylinder block, wherein said at least one auxiliary engine comprises a starter motor including a plurality of magnet switches received in said gap and arranged in parallel with each other.
Claim 7
Dependent Claim
113 words
A construction for mounting engine auxiliary parts on an engine, said mounting construction comprising: bolts threadedly fastened from a side of an engine main body to fix the engine auxiliary parts to said engine main body at the upper and lower positions of said engine auxiliary parts while the upper and lower portions of said engine auxiliary parts confront a crankcase and an oil pan, respectively; wherein axes of said bolts are inclined relative to an axial direction of a cylinder of said engine, and a hook-shaped temporary locking member is provided at a location where at least the upper portion of said engine auxiliary parts is fixed to said engine main body.
Claim 8
Dependent Claim
113 words
A construction for mounting engine auxiliary parts on an engine, said mounting construction comprising: bolts threadedly fastened from a side of an engine main body to fix the engine auxiliary parts to said engine main body at the upper and lower positions of said engine auxiliary parts while the upper and lower portions of said engine auxiliary parts confront a crankcase and an oil pan, respectively; wherein axes of said bolts are inclined relative to an axial direction of a cylinder of said engine, and a hook-shaped temporary locking member is provided at a location where at least the upper portion of said engine auxiliary parts is fixed to said engine main body.
Claim 9
Dependent Claim
125 words
