Abstract
To provide a multi-cylinder engine for a vehicle, in which a pair of cylinder bore rows, each including a plurality of cylinder bores disposed in parallel to each other, are disposed in such a manner as to be perpendicular to a crank shaft disposed substantially in the horizontal direction. Accordingly, a relatively large space can be ensured under a cylinder head. Cam shafts corresponding to cylinder bore rows are disposed over a pair of planes containing the axial lines of cylinder bores constituting the cylinder bore rows, respectively.
Claims9
A multi-cylinder engine for a vehicle, comprising:
- a crank shaft disposed in a substantially horizontal direction in the multi-cylinder engine;
- a pair of cylinder bore rows arranged perpendicular to the crank shaft, each of said pair of cylinder bore rows including a plurality of cylinder bores disposed in parallel with each other;
- cam shafts corresponding to said cylinder bore rows are spaced from and disposed above a pair of planes containing axial lines of said cylinder bores, respectively, wherein each one of said cam shaft operates intake valves and exhaust valves that are disposed substantially above a respective one of said pair of planes;
- and
- wherein said engine is mounted on said vehicle with said cylinder bore rows opposed to each other and with the axial lines of said cylinder bores extending substantially in the horizontal direction, and said crank shaft extends in a longitudinal direction of said vehicle.
A vehicle, comprising:
- a multi-cylinder engine mounted in said vehicle;
- a crank shaft disposed in a substantially horizontal direction in the multi-cylinder engine;
- a pair of cylinder bore rows arranged perpendicular to the crank shaft, each of said pair of cylinder bore rows including a plurality of cylinder bores disposed in parallel with each other;
- cam shafts corresponding to said cylinder bore rows are spaced from and disposed above a pair of planes containing axial lines of said cylinder bores, respectively, wherein each one of said cam shaft operates intake valves and exhaust valves that are disposed substantially above a respective one of said pair of planes;
- and
- wherein said engine is mounted on said vehicle with said cylinder bore rows opposed to each other and with the axial lines of said cylinder bores extending substantially in the horizontal direction, and the crank shaft of said engine extends in a longitudinal direction of said vehicle.
