Abstract
In a V-type internal combustion engine having a crankshaft oriented in a substantially horizontal direction, drainage channels for draining liquid such as rainwater pooling within a recess formed within the V-shaped of the engine are formed in covers for covering the end surface of the internal combustion engine in an axial direction of the crankshaft. Accordingly, liquid such as rainwater pooling on the V-shaped bank of the V-type internal combustion engine is advantageously drained from the engine with the present apparatus and methods.
Claims20
A V-block internal combustion engine comprising:
- a crankshaft orientated in a substantially horizontal direction;
- a V-block cylinder block opening upwardly with respect to the horizontal direction of the crankshaft;
- a V-shaped valley being formed within an upper portion of said V-block cylinder block;
- a cover for covering an end surface of the internal combustion engine with respect to a direction of the crankshaft;
- a drainage channel for draining liquid pooling in the V-shaped valley;
- wherein said V-shaped valley is formed in the cover.
An internal combustion engine comprising:
- at least four cylinders and four pistons of said engine operatively engaged in a four cycle arrangement;
- a crankcase;
- a crankshaft orientated in a substantially horizontal direction;
- a V-block, cylinder block opening upwardly with respect to the horizontal direction of the crankshaft and being connected to an upper end surface of the crankcase;
- a V-shaped valley being formed within an upper portion of said V-block cylinder block;
- a cover for covering an end surface of the internal combustion engine with respect to a direction of the crankshaft;
- a drainage channel for draining liquid pooling in the V-shaped valley;
- wherein said V-shaped valley is formed in the cover;
- an oil pan connected on a lower end surface of the crankcase;
- a pair of left and right cylinder heads;
- a front cover being connected to a front face of the crankcase and V-block cylinder block;
- and
- a rear cover being connected to a rear face of the crankcase and the V-block, cylinder block.
A method of preventing a collection of water in a V-shaped valley of the internal combustion engine, wherein said internal combustion engine is a V-block engine that includes a crankshaft orientated in a substantially horizontal direction;
- a V-block cylinder block opening upwardly with respect to the horizontal direction of the crankshaft;
- the V-shaped valley being formed within an upper portion of said V-block cylinder block;
- a cover for covering an end surface of the internal combustion engine with respect to a direction of the crankshaft;
- a drainage channel for draining liquid pooling in the V-shaped valley;
- said V-shaped valley being formed in the cover, said method comprising the steps of:
- draining liquid accumulating within said V-shaped valley being formed within the upper portion of said V-block cylinder block;
- and
- guiding said liquid through said drainage channel to a position external to said internal combustion engine.
