INTERNAL / EXTERNAL COMBUSTION ENGINE, DRONE, AIRCRAFT, LAND AND MARINE VEHICLE ENGINE, WITH PISTON-DRIVEN ROTORS, HIGH ENERGY EFFICIENCY AND HIGH TORQUE VALUE TURNING LINEAR / CIRCULAR MOTION INTO EACH OTHER, COMPRESSED AIR ENGINE, COMPRESSOR

When the pressure is highest in internal combustion engines where the crankshaft is used, the angle value between the piston axis and the output shaft axis is about 10-15 degrees. Thus, the pressure obtained according to the formula cannot fully affect the torque value of the engine. https://www.youtube.com/watch?v=MZK3gZREi1w

 

 

In conventional internal combustion piston and rotary engines, the combustion stroke begins towards the end of the compression stroke and continues until sometime after the start of the power stroke. The combustion stroke cannot be applied independently of the four strokes. Because of this disadvantage, the friction force increases a lot, mechanical efficiency, thermal efficiency, emission values deteriorate, and accordingly, the overall efficiency decreases specific fuel consumption increases. In today's developing engine technology (SkyActiv-X (SPCCI)), the reason for using the input ignition provided by the spark plug when necessary before the actual combustion is to make this combustion time as independent as possible.

 

 

In these internal combustion engine inventions, the internal rail and/or outer rail, which rotate with each other in certain proportions and in different directions, used a cylinder block that harbors the cylinders and rotates in the same direction as the internal rail. The pistons in the cylinder block continue the cycle by moving to the outer rail after the inner rail, and then back to the inner rail. The Pistons rotate, acting on the periphery of these rails. The engine works with the pressure generated by the combustion of fuel mixed with air taken into the cylinders through the time shaft (1, 2).

At the end of full combustion and the start of the power stroke, the angle value between the piston axis and the output shaft axis is much higher than conventional motors. For this reason, much higher torque can be achieved than traditional internal combustion engines. In addition, during power and exhaust strokes and in the constant volume range where combustion occurs (on time), the piston always acts at an angle of 90 degrees to the rails. Also, at strokes of intake and compression, there is an effect of 90 degrees. Thus, the piston-cylinder mechanism is only subjected to pressure axially.

 

 

Since there is no part connected to the piston in these inventions, the speed of the piston can be changed in a certain amount and position. Combustion occurs in an independent stroke (at the time) of 30 degrees. In this stroke, the speed of the piston is zero. Complete combustion occurs in this volume and time. Thus, with a poor mixture well below the stoichiometric ratio and thermal efficiency for all engine speeds can be much higher than conventional engines. The highest pressure obtained can be applied as the piston begins to move towards the lower dead point. In this sense, the expression independent three-stroke or five-stroke internal combustion engine can be used for these inventions. Thus, in compression ignition engines (CIDI, PCCI, HCCI, SPCCI), the combustion control problem has been solved with these inventions without the need to use Spark Plugs.

 

 

During the combustion stroke, the compression ratio can be changed by changing the rail format.

Conclusion

As for the shape of the crankshaft used in internal combustion engines, it is not a suitable part for converting the potential energy of the fuel into kinetic energy. It causes a significant amount of torque and power loss when converting linear motion into circular motion. This, in turn, leads to more exhaust gas, costs, noise, labor, and weight than it should be.

Internal combustion rotary engines (Wankel etc.) and piston engines have two disadvantages due to the geometry of the crankshaft:

• In designs which is used crankshaft or not used (at rotary engines) and converted to each other linear / circular motion at a given force effect, now of pressure and / or linear / circular motion, the impact position is very close to the upper dead point. This means that the force cannot be converted to a sufficient torque value. Force, pressure, or moment effect can be applied at very low angles. The angle value between the piston axis and the crankshaft is 10-15 degrees at the beginning of power stroke, when the maximum pressure value of the cycle occurs, while this angle value increases as the pressure value decreases. In fact, now when the highest-pressure value is formed, this angle should be as close to 90 degrees as possible. This negatively affects the torque value. In some of the inventions made to eliminate this problem, the pressure at the start of the power stroke was stored using the spring. The piston pressure is then applied to the connecting rod when the pressure angle increases by continuing to rotate the crankshaft (click here for some of the patents). In some of these inventions, additional mechanisms were used with a connecting rod. The aim is again to affect the piston pressure on the connecting rod at the largest possible angle (click here for some of the patents). In some of these inventions, the crankshaft was never used (click here for some of the patents). But in these designs, the problem mentioned below cannot be solved and / or smooth (accurate) circular motion cannot be achieved.

• Conventional internal combustion piston and rotary engines do not have combustion stroke as a separate and independent fifth time from the four strokes formed by intake, compression, power, and exhaust strokes. The five strokes cannot be applied independently of each other, since the combustion stroke, which must be applied before the power stroke goes into other strokes, starts towards the end of the compression stroke, and continues until some stroke after the start of the power stroke. It does not allow enough time to complete combustion. Not enough time when the piston speed is zero. Thermodynamic losses occur due to the start of the combustion process before the piston has yet to reach the upper dead point.

• Conventional internal combustion piston and rotary engines since there is no axial and smooth circular motion, there is vibration.

Because of all these disadvantages, friction power increases a lot, mechanical efficiency, thermal efficiency, emission values deteriorate, and accordingly, overall efficiency decreases, specific fuel consumption increases.

With this invention, these two problems are solved:

In this invention, a design without a crankshaft was made. Linear motion is translated into circular motion with a much higher torque value. At the beginning of the power stroke, when the pressure is highest, the torque angle is 90 degrees. It has a combustion stroke independent of four strokes. There is constant volume stroke for the combustion process. During this time, the piston speed is zero. Combustion carried out at the specified fixed volume in the theoretical Otto cycle. The high pressure stored by complete combustion, which occurs in the process of constant volume (The piston speed is 0 while the output shaft continues to rotate.), is transferred to this rail with a high angle value when moving from fixed rail to an internal or external rail. Thus, the highest torque value is obtained. A very efficient cycle takes place. Due to full combustion, both the pressure increase rate and thermal efficiency are higher than conventional engines. Specific fuel consumption and carbon emissions are less. The engine runs more stable and there is no vibration.

 

In addition, used in conventional internal combustion engines the piston-cylinder mechanism preserved, and thus the existing works, processes, methods, parts, machines, and equipment can be continued to be used.

 

This method can also be used in aircraft engines and even piston jet engine and gas turbine construction. Considering the Exergy economy in a multi-cylinder piston jet engine, the constant change of cylinders that will provide air compression will be positive.

 

This invention is not just about petroleum products. In fact, what is done with this invention is the process of turning linear motion into circular motion with a high torque value. So, it is not just about internal combustion engines. Since circular motion is formed with high torque it can also be a used as an external combustion engine (Stirling engine, etc.). Also, it can be a compressed air-powered engine. With the resulting high torque, two important problems of compressed air engines have been eliminated. Range and noise. It can also be used more efficiently in piston compressors.

 

It can also be used with renewable alternative fuels such as biodiesel. In my invention, natural gas is more efficient because it has a constant combustion stroke. At a high compression ratio, there is no knock on the engine. Because of the geometric shape of the rails, the piston can move to the upper dead point in a very short time. For example, ammonia can be used efficiently in this engine. Because, as mentioned above, there is an independent combustion stroke. Ammonia, which has a low combustion rate, will be able to combustion more efficiently even at high engine speeds in the constant combustion process. In conventional internal combustion engines, no efficient operation was achieved with ammonia alone. But in these inventions, ammonia, which is much more economical, can be used efficiently. At the same time, carbon is not released outside. In addition, ammonia will also be used for cooling, so there will be no need for a cooling device.

 

I do 3D modeling of my invention with MaxScript codes. All parts and dimensions are parametric. All variables are related. For example, when the cylinder diameter value is changed at the code interface, all the values of the mechanism change. Including the diameter value of the washer of the oil drain bolt. (link). Animation data is also performed according to the values specified by variables in MaxScript codes. MaxScript commands used

 

RENEWABLE FUEL-POWERED HIGHLY TORQUE/EFFICIENT, ENVIRONMENTALLY FRIENDLY, SUSTAINABLE IC/EC ENGINE, COMPRESSED AIR-POWERED ENGINE

A mechanism where linear motion with less energy used is converted to circular motion with higher torque

In conventional internal combustion engines, hydrocarbon (HC) seen in the exhaust gas at the end of combustion in cylinders indicates low thermal efficiency. The reason CO (carbon monoxide) is found in the exhaust gas is that during the bad combustion process in the cylinder, the fuel molecule is combined with 1 oxygen instead of 2 due to lack of oxygen. The reason for this is that the fuel is partially combustion. Factors that prevent complete combustion of fuel are that the fuel-air mixture ratio during combustion time is not stable in different parts of the cylinder, the combustion event occurs at a variable and unstable volume, pressure, and temperature, and there is not enough time for complete combustion. However, when complete combustion is achieved in the internal combustion engine, non-harmful carbon dioxide and water come out of the exhaust.

In addition to this disadvantage, the problem that the highest pressure obtained can be transferred to the output shaft with only a very small torque angle is added, which further reduces thermal efficiency along with mechanical efficiency.

The part that causes these two most important problems (partial combustion and small torque angle) is the crankshaft. The crankshaft is not an accurate and efficient part in converting linear/circular motion to each other in internal/external combustion piston engines and mechanisms.

In this case, the solution to the first problem will be possible by creating a combustion time/stroke independent of other strokes and a combustion chamber of constant volume at the end of the compression stroke. Here, the fuel can be completely combusted at a time when the piston can remain stationary while the engine continues to move. In this way, the necessary conditions will be provided for the realization of full combustion. The stable fuel-air mixture in each area of the combustion chamber, constant volume/pressure/temperature, and sufficient time during combustion time.

The solution to the second problem will be possible by transferring the piston's combustion end pressure from the beginning to the end of the power stroke to the output shaft with a different and independent part/mechanism than the connecting rod mechanism to which it is connected.

In this invention, the crankshaft was not used and the solution of the two problems mentioned above was combined. In the combustion process, which is independent of the other four strokes, when the piston speed is zero despite the engine rotation, the highest pressure obtained at the end of full combustion is transferring to the piston with the highest torque angle, and then to the inner rail and/or outer rail.

This invention has two very important differences from traditional internal combustion engines:

1. It has a combustion time independent of the other four strokes. During the combustion time, the piston speed is zero while the engine continues to rotate. So, this engine is a five-stroke engine, as it should be. In this way, a very high thermal efficiency is achieved by providing complete combustion. In this way, less specific fuel consumption is possible while obtaining more power, and harmful emissions are eliminated. In this way, complete combustion of alternative and/or renewable fuels that need a certain combustion time can be achieved. In addition, in the internal combustion engine, where argon gas will be used as an expansion gas, the difficulty of timing the injection of hydrogen into the cylinder has been eliminated.

2. By transferring the highest pressure obtained at the end of complete combustion to the output shaft with the highest torque angle, both thermal efficiency and mechanical efficiency are increased. In this way, on the one hand, more power is obtained, and on the other hand, less specific fuel consumption is possible.

This invention goes far beyond trying to start an internal combustion engine with different kinematics. That kind of hobby works was already done 20 years ago.

As clearly explained in the presentation in the link below, this invention, which has these two important features that are not found in traditional internal combustion engines, has been described as a new generation, environmentally friendly, and sustainable internal combustion engine.

According to the improvements achieved by this invention, it will be possible to use renewable fuels and oil-derived fuels more efficiently to close the gap in electric vehicles that will not meet climate targets alone for the next decades.
