Abstract
A V-type engine includes a housing, a crankshaft, a counterbalance shaft, a first camshaft, and a second camshaft. The crankshaft, the counterbalance shaft, the first camshaft, and the second camshaft are rotatably supported by the housing. The crankshaft has a crankpin. In one embodiment, an imaginary plane perpendicular to the rotational axis of the crankshaft intersects each of the crankpin and the counterbalance shaft such that the crankshaft is operatively coupled with each of the counterbalance shaft and the first camshaft on one side of the imaginary plane, and the counterbalance shaft is operatively coupled with the second camshaft on an opposite side of the imaginary plane. The V-type engine may be included in a vehicle.
Claims21
A V-type engine comprising:
- a housing;
- a crankshaft rotatably supported by the housing and having a crankpin;
- a first piston operatively connected to the crankpin;
- a second piston operatively connected to the crankpin;
- a counterbalance shaft rotatably supported by the housing;
- a first camshaft rotatably supported by the housing and associated with the first piston;
- a second camshaft rotatably supported by the housing and associated with the second piston;
- wherein an imaginary plane perpendicular to the rotational axis of the crankshaft intersects each of the crankpin and the counterbalance shaft, and the crankshaft is operatively coupled with each of the counterbalance shaft and the first camshaft on one side of the imaginary plane, and the counterbalance shaft is operatively coupled with the second camshaft on an opposite side of the imaginary plane.
A V-type engine comprising:
- a housing;
- a crankshaft comprising a crankpin and a first drive element, the crankshaft rotatably supported by the housing;
- a counterbalance shaft comprising a second drive element and a third drive element, the counterbalance shaft rotatably supported by the housing such that the second drive element is operatively coupled with the first drive element;
- a first camshaft comprising a fourth drive element, the first camshaft rotatably supported by the housing such that the fourth drive element is operatively coupled with the first drive element;
- and
- a second camshaft comprising a fifth drive element, the second camshaft rotatably supported by the housing such that the fifth drive element is operatively coupled with the third drive element.
A vehicle having a V-type engine, wherein the V-type engine comprises:
- a housing;
- a crankshaft rotatably supported by the housing and having a crankpin;
- a first piston operatively connected to the crankpin;
- a second piston operatively connected to the crankpin;
- a counterbalance shaft rotatably supported by the housing;
- a first camshaft rotatably supported by the housing and associated with the first piston;
- a second camshaft rotatably supported by the housing and associated with the second piston;
- wherein an imaginary plane perpendicular to the rotational axis of the crankshaft intersects each of the crankpin and the counterbalance shaft, and the crankshaft is operatively coupled with each of the counterbalance shaft and the first camshaft on one side of the imaginary plane, and the counterbalance shaft is operatively coupled with the second camshaft on an opposite side of the imaginary plane.
