Definitions

  • the present invention relates to an internal-combustion engine, and more particularly to an efficient internal-combustion engine comprising multiple cylinder block in series mounted in a single casing, wherein each of the cylinder block comprises multiple cylinders that drive the cylinder block to rotate integrally therewith.
  • An internal combustion engine is a commonly used machine that converts the energy store in some fuel into motion. All internal combustion engines use a "fixed-cylinder" configuration. A piston in a cylinder and a connecting rod between the piston and the main engine shaft convert the expanding gases in burning fuel from reciprocating linear motion initiated in the piston to rotary movement of the main engine shaft thereby supplying energy in the form of a rotating shaft at the output of the engine.
  • this type of the internal combustion engine is inefficient. High-power output requires a large cylinder with many ancillary devices, such as a radiator, fuel pump, carburetor and so on. Thus, fabrication cost and maintenance cost will be high.
  • An internal combustion engine with rotary cylinders in accordance with the present invention tends to mitigate and/or obviate the aforementioned problems.
  • the main object of the present invention is to provide an internal combustion engine comprised of multiple cylinder blocks in series'mounted a single casing, with the advantage of space and/or weight reduction and efficient power and/or performance improvement.
  • an internal combustion engine in accordance with the present invention is a four-stroke engine.
  • the engine is comprised of multiple cylinder blocks (20) in series connected with the main shaft (30) in a circular casing (10). Spark plugs (12) are evenly distributed on the outside of the casing (10). Intake ports (14) and exhaust ports (16) are also defined in the casing (10). The number of spark plugs (12), intake ports (14) and exhaust ports (16) is the same.
  • Each cylinder block (20), which is rotatably fitted in the casing (10), has multiple cylinders (22) and pistons (220) movably received in the cylinders (22) (the figures show 4 cylinders and 4 pistons).
  • the number of pistons (220) is twice the quantity of either the spark plugs (12), intake ports (12) or exhaust ports (14). Namely, there are two spark plugs, two intake ports and two exhaust ports in this embodiment and the angle distance between two similar elements (spark plugs, intake ports or exhaust ports) is 180°.
  • the centerlines of the cylinders (22) are respectively perpendicular to the diameter of the casing (10).
  • a connecting rod (222) is eccentrically pivotally mounted on a pinion (224), and the end of the connecting rod (222) is pivotally connected to the piston (220).
  • the pinion (224) is rotatably attached to the cylinder block (20) by a shaft (226).
  • a main gear (32) is stably mounted on the main shaft (30) by a key (34) to engage each pinion (224).
  • An output shaft (24) is formed on the cylinder block (20) at end.
  • the cylinder block (20) has been rotated clockwise 45°.
  • the pistons (220) of cylinder unit 1 have completed a power stroke and are ready for an exhaust stroke; the pistons (220) of cylinder unit 2 have completed an intake stroke and are ready for a compression stroke. Again, all pistons (220) simultaneously arrive at the bottom of the stroke.
  • the cylinder block (20) continues to rotate due to inertia and/or the driving force from other cylinder blocks, and all pistons (220) are pushed outwards. After having rotated another 45°, the cylinder block (20) arrives at a position such that cylinder unit 2 is in the same position as cylinder unit 1 shown in Fig.1. Now cylinder unit 2 having completed a compression stroke is ready for a power stroke, and cylinder unit 1 having completed an exhaust stroke is ready for an intake stroke. The spark plugs ignites the air-fuel mixture again to repeat the process described above.
  • each cylinder (22) completes one stroke for each 45° the cylinder block rotates, each cylinder (22) will complete an entire four-stroke-cycle, namely, intake, compression, power and exhaust stroke, for every 180° that the cylinder block (20) rotates. Moreover, for every 90° that the cylinder block (20) rotates , two cylinders (22) complete a power stroke to supply energy. Thereby, the cylinder block (20) rotates continuously.
  • the piston (220) and the connecting rod (222) are similar to the conventional elements. It is noted that the connecting rod (222) is eccentrically mounted on the pinion (224) to convert the reciprocating linear motion to rotary motion. Notches (228) are defined in the pinion (224) to offset the weight of the pinion connecting post (unnumbered) and balance the pinion (224) so it will run smoothly.
  • the internal combustion engine comprises multiple cylinder blocks (20) in series mounted in the casing (10), as shown in Fig. 4.
  • the spark plugs (12), intake ports (14) and exhaust ports (16) of adjacent cylinder blocks (20) are staggered by 45°.
  • the spark plugs (12) are in linear arrangement, which facilitates the arrangement of the cooling system of the engine to be located in one place rather than all around the casing (10). Furthermore, from this preferred embodiment as shown, it is to be noted that four sets of cylinder blocks are arranged in the casing (10), each being located at a position with 22.5 degree difference so as that, in terms of power output, there is always power generated at every point in the operation of the engine of the invention. With such an arrangement, the power output will be much smoother than a conventional structure.
  • Table 1 shows piston operating sequence for the engine.
  • the cylinder block (20) in Fig. 1 defines the original position (0°) of cylinder block 1.
  • cylinder unit 1 of cylinder block 1 is ready for a power stroke
  • cylinder unit 2 is ready for an intake stroke.
  • Cylinder blocks 2, 3 and 4 are progressively later than cylinder block 1 by one stroke each, so that "compression/exhaust”, “intake/power”, and “exhaust/compression” are indicated in the corresponding blocks.
  • Cylinder unit 1 of cylinder block 2 and cylinder unit 2 of cylinder block 4 are ready for a compression stroke that will consume energy.
  • cylinder unit 1 of the cylinder block 1 and cylinder unit 2 of cylinder block 3 are ready for a power stroke that will generate energy.
  • the required energy of the compression stroke of cylinder blocks 2 and 4 can be provided by the power stroke of cylinder blocks 1 and 3.
  • energy consumed by the compression stroke is provided by other cylinder blocks that have completed a power stroke.
  • the engine does not need a flywheel to store energy for the compression stroke, so volume and weight of the engine can be reduced dramatically and the engine runs more smoothly.
  • Each row is spaced apart from each other by 22.5 degree (as shown in the attached drawing), such that the power from the power stroke is able to be transmitted much more smoother than the engine having three rows, two rows and one row of cylinders.
  • the number in the parenthesis stands for the power stroke. Therefore, when taking one row four cylinder engine for example, there are two power strokes simultaneously, which is one more than a conventional engine, such that the power output is greater and smoother.
  • connection between the piston (220) and the pinion (224) enables the cylinder block of the engine to rotate around the main gear (32) which is securely fixed (already described in detail in the original specification as filed).
  • the flywheel is no longer needed to store energy for the next stroke.
  • Table 2 depicts the engine's energy state.
  • cylinder unit 1's operating sequence is "power-exhaust-intake-compression”
  • cylinder unit 2's simultaneous operating sequence is later than unit 1 by two strokes and is “intake-compression-power-exhaust”.
  • the total energy output is positive in the rotational sectors 0°-45°, 90°-135°, 180°-225° and 270°-315°, and is negative in the rotational sectors 45°-90°, 135°-180°, 225°-270° and 315°-360°.
  • cylinder unit 1's simultaneous operating sequence is later than cylinder unit 1 of cylinder block 1 by one stroke and is "compression-power-exhaust-intake", and cylinder unit 2's simultaneous operating sequence is "exhaust-intake-compression-power”.
  • the total energy output is positive in the rotational sectors 45°-90°, 135°-180°, 225°-270°, 315°-360°, and is negative in the rotational sectors 0°-45°, 90°-135°, 180°-225°, 270°-315°.
  • the energy output of the two cylinder blocks (20) is complementary, the overall energy output of the cylinder blocks 1 and 2 is always positive.
  • Cylinder blocks 3 and 4 operate in a similar manner to cylinder blocks 1 and 2, and the energy output of cylinder blocks 3 and 4 is also always positive. The combined energy output all these cylinder blocks 1, 2, 3, and 4 operating simultaneously is continuous and smooth without undulation.
  • Table 1 shows the piston operating sequence for the engine.
  • the cylinder block (20) in Fig. 1 defines the original position (0°) of cylinder block 1.
  • cylinder unit 1 of cylinder block 1 is ready for a power stroke
  • cylinder unit 2 is ready for an intake stroke.
  • Cylinder blocks 2, 3 and 4 are progressively later than cylinder block 1 by one stroke each, so that "compression/exhaust”, “intake/power”, and “exhaust/compression” are indicated in the corresponding blocks.
  • Cylinder unit 1 of cylinder block 2 and cylinder unit 2 of cylinder block 4 are ready for a compression stroke that will consume energy.
  • cylinder unit 1 of cylinder block 1 and cylinder unit 2 of cylinder block 3 are ready for a power stroke that will generate energy.
  • the required energy of the compression stroke of cylinder blocks 2 and 4 can be provided by the power stroke of cylinder blocks 1 and 3.
  • energy consumed by the compression stroke is provided by other cylinder blocks that have completed a power stroke.
  • the engine does not need a flywheel to store energy for the compression stroke, so the overall volume and weight of the engine can be reduced dramatically and the engine runs more smoothly.
  • connecting rod (222) which are eccentrically and pivotally connected to a pinion (224) and the pinion (224) is mated to a main gear (32)
  • the power generated by the power stroke from the piston will be transmitted to the main gear (32) by means of the connecting rod and the pinion.
  • No flywheel is necessary to offset the power necessary to drive the motion of other pistons and no crank shaft is necessary to output the power due to the provision of the main shaft
