Description

Internal combustion engine {INTERNAL-COMBUSTION ENGINE}

The present invention relates to an internal combustion engine, and more particularly, having a plurality of cylinder blocks continuously mounted in one casing, each cylinder block having a plurality of cylinders for driving the cylinder block to rotate integrally therewith. It is about an internal combustion engine.

Internal combustion engines that convert energy generated during combustion of fuel into kinetic energy are commonly used in the mechanical field. All internal combustion engines use a "fixed-cylinder" shape. The piston in the cylinder, the connecting rod between the piston and the main engine shaft, is a reciprocating linear movement transmitted to the piston that converts the expansion gas generated during combustion of the fuel into the rotational movement of the main engine shaft, thereby providing The output shaft is rotated. However, this type of internal combustion engine is inefficient. Achieving high power requires a large cylinder with many auxiliary devices such as radiators, fuel pumps and carburators. Therefore, manufacturing cost and maintenance cost are increased.

An internal combustion engine with a rotating cylinder according to the present invention is directed to minimizing and / or eliminating the problems mentioned above.

The main object of the present invention is to provide an internal combustion engine having advantages of space and / or weight reduction and improvement of output efficiency and / or performance since it consists of a plurality of cylinder blocks mounted in series in a single casing.

Other objects, benefits and novel features of the invention will become more apparent from the following description taken in conjunction with the accompanying drawings.

1 and 4, the internal combustion engine according to the invention is a four-stroke engine. The engine consists of a plurality of cylinder blocks 20 connected in series to the main shaft 30 in the circular casing 10. The spark plug 12 is evenly arranged outside the casing 10. The intake port 14 and the exhaust port 16 are further formed in the casing 10. The quantity of the spark plug 12, the intake port 14, and the exhaust port 16 is the same.

Each cylinder block 20 rotatably coupled to the casing 10 includes a plurality of cylinders 22 and pistons 220 rotatably housed within a cylinder 22 (shown in the figure four cylinders and four pistons). ). The number of pistons 220 is twice as large as the number of spark plugs 12, intake port 14 or exhaust port 16. That is, in the present embodiment, two spark plugs, two intake ports, and two exhaust ports are provided, and the relative angle between two identical elements (spark plug, intake port, or exhaust port) is 180 °. The center lines of the cylinders 22 are each perpendicular to the diameter of the casing 10. The connecting rod 222 is pivotally mounted on the pinion 224 and one end of the connecting rod 222 is pivotally connected to the piston 220. This pinion 224 is rotatably mounted to the cylinder block 20 by the shaft 226. The main gear 32 is rotatably mounted to the main shaft 30 by the key 34 to engage with each pinion 224. The output shaft 24 is formed at the end of the cylinder block 20.

As shown in FIG. 1, all cylinders 220 move simultaneously and reach the top of cylinder 22 at the same time. The upper and lower cylinders 22 are vertical, and their coupling pistons 220 installed therein are aligned with the spark plugs 12, waiting for the explosive stroke. For simplicity, the combination of the upper and lower cylinders and the piston is referred to as "cylinder unit 1". The left and right cylinders 22 are arranged horizontally, and their coupling pistons 220 installed in the cylinders have substantially finished the exhaust stroke and are waiting for the intake stroke. For simplicity, the combination of these two cylinders and the piston is referred to as "cylinder unit 2". When the air-fuel mixture of the cylinder 22 above the piston 220 in the cylinder unit 1 is ignited by the spark plug 12, the piston 220 is pushed inward to rotate the cylinder block 20 clockwise. Let's do it.

2, the cylinder block 20 is rotated 45 degrees clockwise. The piston 220 of the cylinder unit 1 waits for the exhaust stroke after completing the explosive stroke, and the piston 220 of the cylinder unit 2 waits for the compression stroke after the intake stroke. Again, all pistons 220 reach the bottom of the stroke simultaneously.

The cylinder block 20 continues to rotate by internal and / or driving forces from other cylinder blocks, and all the pistons 220 are pressed outwards. After rotating 45 ° again, the cylinder block 20 reaches such a position so that the cylinder unit 2 is in the same position as the cylinder unit 1 shown in FIG. The cylinder unit 2 which has completed the compression stroke waits for the explosion stroke, and the cylinder unit 1 which has completed the exhaust stroke waits for the intake stroke. The spark plug again ignites the air-fuel mixer and repeats the above process.

Each cylinder 22 finishes one stroke while the cylinder block rotates every 45 °, so each cylinder 22 is a full four-stroke-cycle, while the cylinder block 20 rotates every 180 °,

Number of cylinder columns Number of cylinders in each row One 2 3 4 5 6 4 90 (2) 45 30 22.5 18 15 6 60 (3) 30 20 15 12 10 8 45 (4) 22.5 15 11.25 9 7.5 10 36 (5) 18 12 9 7.2 6 12 30 (6) 15 10 7.5 6 5 18 20 (9) 10 5 4 20 18 (10) 9 6 4.5 3.6 3

In other words, they will complete the intake, compression, explosion and exhaust strokes. In addition, while the cylinder block 20 rotates every 90 °, the two cylinders 22 supply energy by completing the explosion stroke. Accordingly, the cylinder block 20 rotates continuously.

Referring to FIG. 3, the piston 220 and connecting rod 222 are similar to conventional elements. One thing to note is that the connecting rod 222 must be mounted on the pinion 224 in order to convert the reciprocating linear motion into rotational motion. A notch 228 is formed in the pinion 224 so that the weight of the pinion connecting rod (number omitted) and the balance of the pinion 224 are biased to smoothly operate.

According to the present invention, the internal combustion engine has a plurality of cylinder blocks 20 continuously mounted in the casing 10, as shown in FIG. As shown in FIG. 5, the spark plug 12, the intake port 14, and the exhaust port 16 of the adjacent cylinder block 20 are staggered by 45 degrees. It is also possible to stagger the cylinder block 22 to align the spark plug 12, the intake port 14 and the exhaust port 16.

As shown in FIG. 6, the spark plugs 12 are arranged in a linear manner, thereby allowing the cooling system of the engine to be arranged in one position rather than all around the casing 10. In addition, as can be seen from this preferred embodiment, four sets of cylinder blocks are arranged in the casing 10 and are arranged with a difference of 22.5 ° each, so that the output is always at every operating point of the engine according to the invention. Is generated. Due to such an arrangement, the output is smoother than usual.

Table 1 shows the piston operating sequence for the engine. For the purposes of illustration, the cylinder block 20 in FIG. 1 is defined as cylinder block 1 in its original position (0 °). In this case, cylinder unit 1 of cylinder block 1 is waiting for an explosion stroke, and cylinder unit 2 is waiting for an intake stroke. When cylinder block 1 is rotated from 0 ° to 45 °, cylinder unit 1 and cylinder unit 2 finish the output stroke and the intake stroke, respectively, so that "explosion / intake" is indicated in the block. Cylinder blocks 2, 3 and 4 are each one stroke later in sequence than cylinder block 1, and are indicated in the corresponding blocks as "compression / exhaust", "intake / explosion" and "exhaust / compression". Cylinder unit 1 of cylinder block 2 and cylinder unit 2 of cylinder block 4 are waiting for the compression stroke which consumes energy. At the same time, the cylinder unit 1 of the cylinder block 2 and the cylinder unit 2 of the cylinder block 4 are waiting for the explosion stroke which produces energy. Therefore, the energy required by the compression strokes of cylinder blocks 2 and 4 can be provided by the explosion strokes of cylinder blocks 1 and 3. As shown in Table 1, during one complete cycle, the energy consumed in the compression stroke is supplied by another cylinder block on which the explosion stroke is completed. Since the engine does not need a flywheel to store energy during the compression stroke, it can significantly reduce the volume and weight of the engine, and the engine runs smoother.

Table 1

Cylinder block 1 Cylinder block 2 Cylinder block 3 Cylinder block 4 0-45 ° Explosion / Suction Compression / Exhaust Suction / explosion Exhaust / compression 45-90 ° Exhaust / compression Explosion / Suction Compression / Exhaust Suction / explosion 90-135 ° Suction / explosion Exhaust / compression Explosion / Suction Compression / Exhaust 135-180 ° Compression / Exhaust Suction / explosion Exhaust / compression Explosion / Suction 180-225 ° Explosion / Suction Compression / Exhaust Suction / explosion Exhaust / compression 225-270 ° Exhaust / compression Explosion / Suction Compression / Exhaust Suction / explosion 270-315 ° Suction / explosion Exhaust / compression Explosion / Suction Compression / Exhaust 315-360 ° Compression / Exhaust Suction / explosion Exhaust / compression Explosion / Suction

For example, an engine with four rows of cylinders, each row with four cylinders:

Since each row is spaced 22.5 ° apart (as shown in the accompanying drawings), the power output during the explosion stroke can be transmitted much more smoothly than an engine with three rows, two rows and one row of cylinders. Note that the number in parentheses indicates the explosion stroke. Therefore, for example, a single-row four-cylinder engine is taken as an example, since two explosion strokes, which are many, occur at the same time as compared with a normal engine, the output is further increased and smoothed.

In addition, the engagement between the piston 220 and the pinion 224 allows the cylinder block of the engine to rotate around the main gear 32 which is rigidly fixed (as described in detail in the original specification of the original application). Therefore, as the cylinder block rotates around the main gear, a flywheel for storing energy for the next stroke is no longer needed.

Table 2 shows the energy states of the engines. In cylinder block 1, the operation order of cylinder unit 1 is in the order of "explosion-exhaust-intake-compression", and cylinder unit 2 is "intake-compression-explosion-exhaust" which is a simultaneous operation sequence two strokes later than cylinder unit 1. Is in order. Overlapping the two units, the total energy output is positive at the rotating sectors 0 ° -45 °, 90 ° -135 °, 180 ° -225 ° and 270 ° -315 °, and the rotation sector 45 ° -90 °, 135 ° Negative at -180 °, 225 ° -270 ° and 315 ° -360 °.

In cylinder block 2, the simultaneous operation sequence of cylinder unit 1 is in the order of "compression-explosion-exhaust-intake" which is one stroke later than the cylinder unit 1 of cylinder block 1, and the simultaneous operation sequence of cylinder unit 2 is "exhaust- Intake-compression-explosion. When two units are overlapped, the total energy output is positive in the rotating sectors 45 ° -90 °, 135 ° -180 °, 225 ° -270 ° and 315 ° -360 °, and the rotation sector 0 ° -45 °, 90 ° Negative at -135 °, 180 ° -225 ° and 270 ° -315 °. Since the energy output of the two cylinder blocks 20 is complementary, the total energy of the cylinder blocks 1 and 2 is always positive. Cylinder blocks 3 and 4 operate in the same way as cylinder blocks 1 and 2, and the energy output of cylinder blocks 3 and 4 is always positive. The combined energy outputs of all of these cylinder blocks 1, 2, 3 and 4 operating simultaneously are continuous and smooth without relief.

Advantages of the present invention are as follows.

1. This internal combustion engine does not require a flywheel, so the volume and weight of the engine are significantly reduced.

2. Since the internal combustion engine according to the present invention is simpler and more efficient, the manufacturing cost and the maintenance cost are low.

3. More cylinder blocks can be added to the internal combustion engine according to the invention to obtain the desired output.

Table 1 also shows the operating sequence of the pistons for the engine. In FIG. 1 the cylinder block 20 defines the original position (0 °) of the cylinder block 1. When the cylinder block 1 is rotated from 0 ° to 45 °, the cylinder unit 1 and the cylinder unit 2 finish the explosive stroke and the intake stroke, respectively, and thus are marked as "explosion / intake" in the block. Since cylinder blocks 2, 3 and 4 are each one stroke in sequence later than cylinder block 1, "compression / exhaust", "intake / explosion" and "exhaust / compression" are indicated in the block. Cylinder unit 1 of cylinder block 2 and cylinder unit 2 of cylinder block 4 are waiting for the compression stroke which consumes energy. At the same time, the cylinder unit 1 of the cylinder block 1 and the cylinder unit 2 of the cylinder block 3 are waiting for the explosion stroke which produces energy. Therefore, the energy required by the compression strokes of cylinder blocks 2 and 4 can be provided by the explosion strokes of cylinder blocks 1 and 3. As shown in Table 1, during one complete cycle, the energy consumed in the compression stroke is supplied by another cylinder block on which the explosion stroke is completed. Since the engine does not need a flywheel to store energy during the compression stroke, it can significantly reduce the volume and weight of the engine, and the engine runs smoother.

In addition, the output transmission uses a connecting rod 222 pivotably connected to the pinion 224, and since the pinion 224 is engaged with the main gear 32, the power generated from the piston by the explosion stroke is It will be transmitted to the main gear 32 via the connecting rod and pinion. No flywheel is needed to offset power and drive other pistons, and no crankshaft is needed to dissipate power due to the provision of the main shaft.

Although many features and advantages of the present invention have been described so far, the detailed description thereof, together with the structure and function of the present invention, is merely illustrative, and in particular, specific changes in shape, size, and arrangement of parts may be realized from the principles of the present invention. It is possible to extend it sufficiently by the broad meaning and expression which the term in an attached claim claims.

Since the internal combustion engine of the present invention does not require a flywheel, the volume and weight of the engine are considerably reduced, and simpler and more efficient, thus lowering manufacturing and maintenance costs. Also, more cylinder blocks can be added to get the desired output.
