Problems solved by technology

However, there are still key problems such as high processing requirements for core parts, too sensitive to wear, difficult adjustment of compression ratio, low thermal efficiency, etc., and it is still difficult to improve the combustion utilization rate
At the same time, similar to the piston internal combustion engine, the scalability of the triangular rotor internal combustion engine structure is also limited
In addition, when the expansion force generated by the fuel is converted into the power of the output shaft, there are natural defects in the transmission of force
Although the expansion force can push the rotor to rotate, it is difficult to increase the torque of the resultant force on the rotor shaft, and the proportion of internal friction is also too high

Embodiment 1

[0047] See attached Figure 4 , Assuming that the rotor compartment is fixed, the cam rotor is a disc cam with a section of far rest area and a section of near rest area, and both the far rest angle and the near rest angle are slightly less than 180°. The number of sliders is 2, symmetrically arranged. The sealing relationship after assembly is as before and will not be repeated. Two air inlets and two air outlets are arranged on the rotor compartment and are located on both sides of the sliding block. Both are indicated by switch symbols. The air inlet is the one with a small circle. A pair of intake and exhaust ports are a group, along the direction of cam rotation indicated by the arrow, the intake ports in the same group are in the front, and the exhaust ports are not limited. Two ignition devices are provided.

[0048] The two sliding blocks divide the rotor and the rotor compartment into two left and right working chambers. As the volume of the two chambers changes at the...

Embodiment 2

[0057] Pass again below Figure 5 with 6 Demonstrate a slightly more complicated situation.

[0058] The rotor compartment is fixed, and the cam rotor with cam profile is used as the output part. There are three sliders on the rotor compartment to evenly divide the rotor compartment into three sections. The cam rotor has a far rest area and a near rest area. The angle of repose is roughly as shown in the figure, that is, the far rest area of ​​the cam rotor and the two sliders The corresponding central angles are similar, and the space between the two sliders is the working chamber or combustion chamber. Figure 5 with 6 Shows the corresponding valve state and working process in the cavity when the rotor is in different positions. As in the previous example, there are three working chambers. At the beginning, each chamber has two possible working processes, so there are 8 different combined working modes. Only two are shown here, and the rest will not be discussed one by one.

[0069] Figure 7 Further demonstrate the variability. As long as the circumferential space is large enough, the number of sliders and the number of cam peaks (such as the remote rest area) can be increased at will. With the addition of the slide escapement device, the size of the working space for completing each work cycle can also be changed.

[0070] The parameter relationships selected below are just for the convenience and clarity of explanation and are not restrictive. In the figure, it is assumed that the remote resting sections of the cam rotor are two evenly distributed, and the arc length of the resting section is slightly larger than the corresponding arc length of two adjacent sliders, so that the two sliders are in a retracted state at the same time. The number of sliders is 6 and they are evenly distributed, indicated by numbers. Each slider is controlled by a slider escapement, where "disengaged" means that the slider has been released by the escapement, "contro...

Abstract

The invention discloses a power system of an internal combustion engine with slide blocks combined with a cam roller, belongs to the field of internal combustion engines and relates to the power system of the internal combustion engine with slide blocks combined with the cam roller. In the power system, a cam mechanism is formed by means of the cam roller and a plurality of slide block driven members, and a plurality of peripherally distributed sealing work chambers are formed with a rotor cabin and an end portion member; these change in volume along with rotation of the cam roller and are matched with an air valve to finish four processes: air suction, compression, acting and exhausting of Otto cycle so as to directly convert chemical energy generated by gas combustion into mechanical energy of the roller in a form of rotation of a fixed shaft. High pressure gas directly pushes the fixed shaft of the rotor to rotate and outputs power, so that the power system is simple in structure and large in parameter adjustable range. Controlled by an additional slide block escaping, the rotor is easily flexibly controlled, and even can rotate forward and backward. Compared with a power system of a piston internal combustion engine and a power system of a triangular rotor internal combustion engine, the power system disclosed by the invention has many prominent advantages.

Description

Technical field [0001] The invention belongs to the field of internal combustion engines, and relates to a sliding block and cam rotor internal combustion engine power system. Background technique [0002] Piston internal combustion engine is the first internal combustion engine to come out. Its characteristic is that the piston makes reciprocating linear motion in the cylinder, and realizes the output of crankshaft rotary motion through the crank slider mechanism. Within two revolutions of the crankshaft, the cylinder completes a complete four working processes of intake, compression, work, and exhaust, namely the Otto cycle. It is generally believed that the piston internal combustion engine has the advantages of high thermal efficiency, compact structure, strong maneuverability, and easy operation and maintenance. It is even believed that the power plant of the piston internal combustion engine, especially the mechanical structure, has reached its peak. However, the output p...
