摘要： A four stroke internal combustion engine is disclosed comprising at least one cylinder arrangement, an exhaust conduit, and at least one turbine. The cylinder arrangement comprises an exhaust port arrangement configured to open and close an exhaust flow area, ACYL. The cylinder arrangement has a maximum volume, VMAX. The exhaust conduit extends between the exhaust flow area, ACYL, and a turbine wheel inlet area, ATIN, of the turbine and has an exhaust conduit volume, VEXH that is ≤0.5 times the maximum volume, VMAX. The exhaust port arrangement is configured to expose the exhaust flow area, ACYL, at a size of at least 0.22 times the maximum volume, VMAX, when a piston of the cylinder arrangement is at the bottom dead centre, BDC.

摘要： The present invention relates to a mechanism (1) comprising: a support (2) including a base (3), a rocker arm (4), and suspension rods (5) hinged to the base (3) and to the rocker arm (4); two toothed wheels (12; 22) which can rotate about the respective axes (A1; A2) thereof; two eccentric elements (14; 24) that rotate as one with the toothed wheels (12; 22), generating moments of gravitational force about the respective axes (A1; A2) thereof; and a link rod (60; 160) comprising a rotary head (62) and an eccentric head (63). The aforementioned axes (A1; A2) are parallel in a horizontal or vertical reference plane (PO). The rocker arm (4) supports the axes (A1; A2) of the toothed wheels (12; 22) and the eccentric elements (14; 24). The suspension rods (5) are inclined by an angle of between 45 degrees and 80 degrees relative to a vertical plane. The toothed wheels (12; 22) mesh with one another with a unit transmission ratio and are rotatable in opposite directions. When the mechanism (1) is operating, the eccentric elements (14; 24) define an elliptical movement, while the rocker arm (4) defines a movement of travel having a vertical component and a horizontal component. The moments of gravitational force from the eccentric elements (14; 24) have the same value and direction, which can vary depending on the angular position thereof about the axes (A1; A2). For each angular position of the toothed wheels (12; 22) and the eccentric elements (14; 24) about the axes (A1; A2), the mechanism (1) has an equilibrium configuration at rest.

摘要： A four-stroke engine comprises an oil tank (2), a crankshaft chamber (1), a distribution chamber (5), a rocker chamber (4), a combustion chamber (9), and a lubricating system. The oil tank (2) is communicated with the crankshaft chamber (1) through an oil supply channel (21). The crankshaft chamber (1) is communicated with the distribution chamber (5) through a first oil transmission channel (15) and a unidirectional valve (151) is disposed in the first oil transmission channel (15). The rocker chamber (4) is communicated with the crankshaft chamber (1) through at least one oil return channel (41), and a unidirectional valve (413) is disposed in each oil return channel (41). The distribution chamber (5) is communicated with the oil tank (2) and used for separating an oil-gas mixture into oil mist and fluid oil. The four-stroke engine further comprises a cam (7) and a transmission mechanism (8) connected between the cam (7) and a crankshaft of the crankshaft chamber (1) in a matched manner. The cam (7) is matched with a rocker (44) of the rocker chamber (4) and located above the combustion chamber (9). The four-stroke engine has a simple lubricating system, and is desirable in operation stability and low in noise.
