Zero-volume internal combustion engine

Abstract

This technology achieves two effects by adding a piston above the internal combustion engine piston to change the size of the combustion chamber. It allows the piston to expel all exhaust gas left over from combustion during the exhaust process, so the torque can be increased by about 30%. The torque reduction at low and ultra-high speeds is very small, so the maximum effective speed is doubled, and the power is doubled, far exceeding the power of ordinary internal combustion engines. Combined with the reflux internal combustion engine and the oil-driven three-camshaft angle stepless adjustment mechanism, it can also effectively reduce light-load fuel consumption and light-load vibration of the reflux internal combustion engine. Although the system has added pistons, connecting rods and cylinder sleeves, all devices that improve the intake effect can be omitted, such as timing advance, valve lift, exhaust gas supercharging system, and a series of complex mechanisms. The second drive method is combined with the reflux internal combustion engine to achieve another effect, which can effectively reduce the light-load vibration of the reflux internal combustion engine and the vibration of the diesel version.

[0001] Internal combustion engine field Background Art

[0002] At present, there is no perfect method for treating the exhaust gas remaining in the cylinder of the internal combustion engine, which leads to a large decrease in the intake volume at high speed, and it is naturally difficult to achieve a higher power breakthrough. This technology effectively solves this technical difficulty and can also effectively reduce the vibration of the diesel version under light load and other advantages. Summary of the invention

[0003] The mechanism of the present invention has two driving modes, but the structure is basically the same. First, the principle is as follows: Figure 1 The combustion chamber 15 becomes smaller by the downward movement of the piston 16, and the combustion chamber 12 becomes larger by the upward movement of the piston 13. The principle is to change the size of the combustion chamber.

[0004] The first drive mode Figure 5 The crankshaft toothed disc 94 drives the toothed disc 93, which in turn drives the zero-product piston to drive the toothed disc 95 to rotate the eccentric shaft surface 34, pushing the connecting rod 59 to drive the piston 54, thereby completing the size change of the combustion chamber 51. Figure 3 It is a combined diagram of the oil-driven three-camshaft angle stepless adjustment mechanism of the reflux internal combustion engine. The crankshaft rotates two circles, and the zero-product piston drive shaft 32 and the intake angle steplessly extend the camshaft 41 to rotate one circle. When the piston 49 reaches the top of the exhaust stroke, the piston 54 is at the bottom, and the combustion chamber 51 becomes zero-product, and the exhaust valve just exhausts all the exhaust gas. When the piston 49 rotates one circle and reaches the top of the compression stroke, the piston 54 is at the top, and the combustion chamber 51 becomes the largest. At this time, it is the optimal combustion chamber size for full load. Since the zero-product piston drive shaft 32 has some load, the conventional timing chain drive method is changed to a timing gear drive. Figure 5 More reliable, Figure 2 It is a top view of the stepless adjustment mechanism of the three camshafts with oil driven angle with the return internal combustion engine. Due to the size of the cylinder diameter, two intake valves and one exhaust valve are selected. Only one intake valve needs to be controlled to achieve the effect of steplessly extending the intake angle. In order to simplify the structure, the intake and exhaust valve drive shafts and the zero-product piston drive shaft share a common shaft 21. The intake angle steplessly extended camshaft 26 controls one valve, achieving the dual effects of no residual exhaust gas in the cylinder and no vacuum operation in the cylinder, and can also solve the vibration caused by multiple superposition of light-load return exhaust gas of the return internal combustion engine.

[0005] The second driving mode Figure 4 , by driving the motor to row the oil cylinder 90, driving the piston drive shaft 62, the eccentric surface 61 rotates to push the connecting rod 89 and then push the piston 84 up and down to complete the change of the size of the combustion chamber 81. The size of the combustion chamber 81 depends on the size of the throttle. If the throttle remains unchanged, the motor rowing the oil cylinder 90 does not move and the size of the combustion chamber remains unchanged. Figure 4It is a diagram combined with a three-camshaft oil-driven stepless angle adjustment mechanism for a reflux internal combustion engine. The intake and exhaust valve camshaft 65 controls one intake valve and one exhaust valve, and the intake angle steplessly extended camshaft 71 controls one intake valve, which solves the vibration caused by multiple superpositions of light-load reflux exhaust gas in the reflux internal combustion engine. Compared with the first driving method, there is no energy loss because the piston 84 is not driven by the crankshaft, but there is no increase in torque and power. It is suitable only for fuel consumption and can also be used for diesel versions. The size of the combustion chamber determines the cylinder pressure. The intake amount is controlled by controlling the intake angle and steplessly extending the camshaft. In conjunction with the control of the size of the combustion chamber 81, the intake amount of the light-load diesel engine is greatly reduced, which greatly reduces the vibration and exhaust emissions of the light-load. Compared with the diesel version of the reflux internal combustion engine, the reliability is greatly improved.

[0014] The first driving mode is as follows Figure 5 Crankshaft toothed disc 94 drives toothed disc 93 to drive zero-product piston camshaft toothed disc 95, driving Figure 3The zero-product piston drive shaft 32 drives the eccentric shaft surface 34 to push the connecting rod 59 and then push the piston 54 up and down, changing the size of the combustion chamber 51. When the engine piston 49 reaches the top of the exhaust stroke, the piston 54 just drops to the lowest point and the combustion chamber 51 is zero. When the engine rotates one circle, the piston 49 reaches the top of the compression stroke and the piston 54 just rises to the highest point. The combustion chamber 51 becomes the optimal size for full load. Combined with the reflux internal combustion engine oil-driven three-camshaft stepless angle adjustment mechanism, the intake angle steplessly extends the camshaft 41, achieving the dual effects of no residual exhaust gas in the cylinder and no vacuum operation in the cylinder.

[0015] The second driving mode is as follows Figure 4 The motor cylinder drive 90 drives the lever 91 to rotate the piston drive shaft 62, pushes the eccentric surface 61, drives the connecting rod 89, and pushes the piston 84 to adjust the size of the combustion chamber 81. The size of the combustion chamber depends on the throttle size. The larger the throttle, the larger the combustion chamber. The intake and exhaust valve camshaft 65 controls the intake and exhaust valves 68. The intake angle steplessly extended camshaft 71 controls the intake angle steplessly extended valve 69, thereby achieving the effect of controlling cylinder pressure and operating without vacuum.
