Definitions

  • This invention relates to internal combustion engines. DISCUSSION OF THE PRIOR ART
  • the engine may include an outer casing for rotatably supporting the cylinder block. Suitable bearings may be provided which can be carried by the outer casing for supporting the cylinder block.
  • the casing comprises two parts which are securable together with the cam being secured between the two parts.
  • a back pressure port may be provided which provides communication between the cavity between the piston and the outer casing and the delivery chamber.
  • the arrangement is such that the pressure built up as the pistons move to their outer position is used to force fuel through the inlet port.
  • the exhaust discharge means may be similar of configuration to that of the fuel delivery means.
  • it may include a discharge port for discharging gases from the combustion chamber and valve means for selectively controlling the discharge.
  • the exhaust discharge means may comprise a discharge chamber disposed within the main casing with a discharge port and a transfer channel as is the case for the fuel inlet means. Valving is effected in the same manner, that is by rotation of the boss.
  • the inlet means is disposed in one side of the casing with the exhaust means in the other side of the casing.
  • the use of the one set of ports firstly for delivering the fuel charge to the combustion chamber and then discharging the exhaust gases from the combustion chamber provides several advantages. Firstly the exhaust gas is maintained at a relatively low temperature because of the cooling effect of the incoming fuel charge. This has the advantage that the engine may be run without the need for external cooling systems. Secondly the incoming fuel charge is preheated by the parts thus creating greater turbulence in the combustion chamber and enhancing complete combustion.
  • the delivery ports comprises a plurality of slots disposed around the cylinder so that port size can be maximized, and thus minimise the amount of movement by the pistons to open and close the ports. Furthermore, contamination of the fresh fuel charge is minimized due to its even spread into the cylinder.
  • the engine may further include secondary cam means which, under certain circumstances, can direct the pistons to their second position.
  • secondary cam means which, under certain circumstances, can direct the pistons to their second position.
  • the combustion of the fuel causes the pistons to move towards the second position.
  • a secondary cam means may be provided.
  • Such secondary cam means may comprise a pair of cams disposed on each side of the pistons which are engageable with a pin which conveniently is an extension of the gudgeon pin for mounting the roller bearing to the piston.
  • the secondary cams are of complementary shape to the cam surface on the primary cam.
  • the gudgeon pins are adapted to be received in slots in the cylinder block wall.
  • the slots may be open at the peripheral outer end of the cylinder block.
  • the slots are closed at the outer end i.e. the slots terminate short of the outer end. This latter arrangement ensures uniform expansion of the cylinder block and inhibits seizure of pins within their associated slot due to concentrated expansion in the weaker area of the slots.
  • the engine operates by combustion of a liquid or gas fuel mixture combined within the combustion chamber compressed and ignited. The resultant energy thus released forces the two pistons apart towards their second position. The energy transmitted from the two movable pistons forces the attached followers against opposed first surface portions of the fixed cam.
  • the engine in its preferred form uses two power cycles per revolution with the use of only one cylinder and consists of only one moving part other than the piston assemblies. DESCRIPTION OF THE DRAWINGS

  • Figure 17 is a cross-sectional view taken along the lines B-B of Figure 9
  • Figure 18 is a cross-sectional view taken along the lines A-A of Figure 9
  • the internal combustion engine which is illustrated in the drawings that accompany this specification in summary comprises a cylinder block 10 rotatably mounted in an outer casing.
  • the cylinder block has an elongate open ended cylinder 20 which houses a pair of piston assemblies 30 and 35, positioned with their crowns facing one another to define a combustion chamber.
  • the opposite end of each piston is associated with a cam follower 41, 41A that engages a fixed cam 46 that is secured to the outer casing.
  • the pistons On combustion of an air/fuel mixture within the combustion chamber, the pistons are forced to reciprocate outwardly of the cylinder which in turn causes the cylinder block to rotate about the outer casing through the agency of the cam and cam followers. Power output is taken from the rotating cylinder block.
  • the engine can run on either a two or four-stroke cycle with either spark ignited petrol or a high compression diesel ignition system.
  • the followers are in the form of thrust bearing rollers which rotate around axes parallel to the axis A-A.
  • the followers (41, 41a) are positioned to face out of the cylinder openings (21, 22) so that they are able to ride on the stationary cam (46).
  • the cam (46) is of a oval-like shape, with the exact shape of the oval being specifically design for the particular operation of the engine.
  • the cam is mounted onto the outer casing (3) and surrounds the circumference of the main body of the cylinder block.
  • the secondary cams engage with the protruding ends of the gudgeon pins (42, 42a) of each piston and, together with the cam (46), confines the pistons to move within the cylinder (20) in a predetermined way in constant contact with the cam.
  • the secondary cams (70, 71) ensure that the pistons move away from each other when required, while the cam (46) urges the pistons towards each other.
  • Output from the engine is obtained from the shaft (15) extending from the other boss (13).
  • a spark plug (57) is provided to ignite the air/fuel mixture in the combustion chamber (23).
  • the spark plug is mounted within the centre of one of the bosses (12) and shafts (14) of the cylinder block (10), thereby extending outside the engine. This allows for easy access to the spark plug when required. When the fuel is diesel, such a spark plug will not be required since high compression of the air/diesel mixture will cause ignition.
  • the second embodiment differs form the first embodiment in the way fuel delivery and exhaust gas removal is achieved.
  • the air/fuel mixture enters the engine via a casing inlet port (90) from where it passes through a delivery passage (80), an inlet valve (81), a transfer passage (82) and a transfer valve (89) to a cavity region (85).
  • the cavity region (85) is defined as the region between the casing (3) and the cylinder block (10).
  • the air/fuel mixture is compressed within the cavity region as a result of the outward motion of the pistons (30, 35).
  • an inlet passage (86) which is located along on of the bosses (13) of the cylinder block (10), is opened to the cavity region (85), resulting in the air/fuel mixture flowing from the cavity region to the combustion chamber (23) via transfer ports (87).
  • Figures 5 and 6 show these components in more detail. Rotation of the cylinder block and the inward movement of the pistons close the transfer ports. After the combustion of the air/fuel mixture the pistons are forced apart, resulting in the transfer ports (87) opening again. The exhaust gases leave the combustion chamber (23) via the transfer ports (87), a outlet passage (92), an exhaust passage (91) and out of the engine through a discharge outlet (88).
  • the operation of the engine will now be described with reference to figures 19 and 20. Apart from the fuel delivery and discharge of exhaust gases, both embodiments operate in a similar manner.
  • the engine operates by employing the internal combustion engine principle. That is, a liquid or gas air/fuel mixture is confined, compressed and then ignited. The resulting expansion due to combustion of the air/fuel mixture is converted to mechanical energy which is employed to drive a load.
  • the engine uses a double acting revolving valve system that ensures correct metering of fuel mixture and prevents the release of fuel into the atmosphere, thus overcoming one of the major disadvantages of the conventional two stroke engine.
  • cam design flexibility also allows the engine to be designed for a particular purpose, such as a high-speed low-torque application or a low-speed high-torque application or even constant speed applications without compensating features such as torque converters. It is an important feature of the cam that, within certain limits, any desired velocity profile and any acceleration/deceleration curve can be designed into the cam.

Abstract

Un moteur à combustion interne possède un bloc cylindre (10) monté en rotation autour d'un axe A-A dans un bâti externe (3), le bloc cylindre (10) ayant un alésage diamétral le traversant pour former un cylindre (20) abritant une paire de pistons (30, 35) positionnés avec leurs têtes (31, 36) se faisant face pour former une chambre de combustion (23). Un galet de came (41, 41A) en contact avec une came de forme ovale (46) fixée au bâti externe (3) autour de la circonférence du bloc cylindre (10), est fixé à la jupe (32, 37) de chaque piston (30, 35) par l'intermédiaire d'un axe de piston (42, 42A). Par combustion d'un mélange air-combustible à l'intérieur de la chambre de combustion (23), les pistons (30, 35) sont poussés vers l'extérieur du cylindre (20) ce qui provoque, à son tour, la rotation du bloc cylindre (10) autour de l'axe A-A par l'intermédiaire de la came (46) et des galets (41, 41A). La puissance est délivrée par l'intermédiaire d'un arbre (15) coaxial à l'axe A-A s'étendant à partir d'un moyeu (13) fixé au bloc cylindre (10). Le moteur peut fonctionner en deux ou quatre temps soit à l'essence en allumage par bougie, soit au diesel en allumage par compression.
