Abstract
A driving engine for vehicles has at least two cylinders aligned with one another and engaged by respective pistons in a sliding manner, each of which is connected with a crankshaft by means of the interposition of a connecting rod, and is delimited by a free face having a first width, measured parallel to a rotation axis of the crankshaft, smaller than a second width measured transverse to the first width.
Claims10
A driving engine for vehicles comprising a crankshaft mounted so as to rotate around a rotation axis;
- at least one first group of cylinders comprising, in turn, at least two first cylinders aligned with one another in a first direction, which is parallel to the rotation axis of the crankshaft;
- a first piston, which is engaged in each first cylinder in a sliding manner and is delimited by a free face;
- and at least one first connecting rod interposed between each first piston and the crankshaft;
- the free face of each first piston having a first width (L1) measured parallel to the first direction and a second width (L2) measured parallel to a second direction, which is transverse to the first direction;
- and characterized in that the first width (L1) of each first piston is smaller than the second width (L2);
- a second group of cylinders comprising, in turn, a plurality of second cylinders, which are as many as the first cylinders, are aligned with one another in the first direction and are engaged, in a sliding manner, by respective second pistons connected to the crankshaft by means of respective second connecting rods;
- wherein each first connecting rod is engaged by the crankshaft in a rotary manner and is directly coupled to a corresponding second connecting rod in a rotary manner.
