Definitions
- the present invention relates to a double-acting engine with collector shaft and cam wheels.
- the ignition is either by compression (Diesel) or controlled (electric spark).
- the opening and closing of the valves is done thanks to the movement of the judiciously arranged cams.
- the object of the invention is to produce an eight-cylinder engine (in our example) with double effect which, thanks to the distribution of the cylinders, makes it possible to have a reduced number of moving parts; which reduces wear, therefore, improves reliability and performance.
- the engine according to the invention is characterized in that two cylindrical blocks, integral, are arranged in opposition, horizontally, each block is pierced by four horizontal cylinders (two at the top and two at the bottom), the rear block being traversed by a groove extending from its upper part to its middle to allow the passage of the collecting shaft.
- This arrangement makes it possible, for an eight-cylinder engine, to reduce the number of pistons to four, the number of connecting rods to one, and the crankshaft size by one eighth.
- the symmetrical location of the cam wheels relative to each other will help reduce vibrations.
- Fig.l is a perspective view of the engine.
- Fig.2 shows an exploded view of the motor.
- the massive part of the collector shaft 2 is mounted between the two cylinder blocks of the frame 1, while the cylindrical part of the shaft is placed in the groove of the rear block so as to form a slide link.
- the four pistons 3 are introduced by the cylinders of the front block until passing through the massive part, itself pierced, of the collecting shaft 2 where they will be blocked in their middle, pierced, by blocking pins 4.
- the rear cylinder head 5 with its valves and springs, is fixed to the rear block of the frame 1 allowing the rear end of the collecting shaft 2 to pass through the orifice located in the center of the cylinder head.
- the wheel is mounted so as to have a pivot connection with the rear cylinder head 5.
- buttons 3, collector shaft 2 thus formed, can slide in an alternating movement in the slide of the frame
- the reciprocating rectilinear movement is transformed into rotary movement thanks to the connecting rod 9 whose head forms a pivot connection with the crankshaft 11 and the foot constitutes another connection pivot with the axis 10.
- the end of the collector shaft 2 is linked by the axis 10 to the slide 8, the latter forms a slide connection with the frame 1, and the other cam wheel 18 is mounted so to form a pivot connection with the cylinder head 17.
- the distribution of the cylinders means that when two cylinders (arranged diagonally), from the front block of the frame 1 are, for example, in the compression phase, the other two are in the exhaust phase, while in the rear block of the frame 1 two cylinders, still diagonally, are in the suction phase, and the other two are in the expansion phase.
- valves are opened thanks to the cams, twelve in number, six for the intake and six for the discharge, distributed on the cam wheel (6 and 18) so the transmission ratio is 1/12.
- the order of opening and closing the valves of the valves is illustrated by considering, for example, the position of the pistons, of the front unit, at bottom dead center (PMB), therefore two cylinders are at the start of the exhaust phase and the two others at the start of the compression phase.
- PMB bottom dead center
- TDC top dead center
