The present invention will be described in further detail below with reference to the drawings and embodiments, so that those skilled in the art can better understand the technical solutions of the present invention.
Please refer to fig. 1 to 10.
In one embodiment, the valve train of the engine provided by the embodiment of the invention comprises valve components, and each cylinder of the engine is provided with at least two groups of valve components.
At least one group of air distribution components are adjustable air distribution components, each adjustable air distribution component comprises an air inlet valve 11, a first cam 1, a main oil cavity 10, a first piston 9, an air valve oil cavity 12, a second piston 8, an oil discharging oil way 6 and an oil discharging control valve group for controlling the opening and closing of the oil discharging oil way 6, the first piston 9 is in sliding sealing connection with the main oil cavity 10, and the first cam 1 is in butt joint with the outer surface of the first piston 9 to push out liquid in the main oil cavity 10. For easy assembly and processing, the main oil chamber 10 and the valve oil chamber 12 are formed on the same structure.
Specifically, the first piston 9 is connected to the wall surface of the main oil chamber 10 via a first elastic connection member. The second piston 8 is connected to the wall surface of the valve oil chamber 12 by a second elastic connection.
The valve oil chamber 12 communicates with the main oil chamber 10, and specifically, the valve oil chamber 12 is connected with the main oil chamber 10 through the control oil passage 7. The outer surface of the second piston 8 acts on the valve rod end of the intake valve 11, and the second piston 8 is in sliding sealing connection with the valve oil cavity 12 so as to push the intake valve 11 to open under the pushing of liquid in the valve oil cavity 12. The oil discharge oil passage 6 communicates with the main oil chamber 10. In a specific process, the control oil passage 7 may be formed by forming a hole in the connection plate 4.
In one embodiment, the valve train of the engine further comprises a control module, and the valve assembly is in signal connection with the control module to control the valve assembly to work.
As can be seen from the above description, in the valve actuating mechanism provided by the application, the first piston 9 is driven to move by the first cam 1, so that the oil in the main oil cavity 10 enters the valve oil cavity 12 to push the intake valve 11 to move, and the oil discharge oil way 6 communicated with the main oil cavity 10 is further provided, so that when the engine works, different lift vortices can be formed by adjusting the oil discharge control valve group, the combustion speed is improved, the combustion sufficiency is improved, and the gas consumption and the exhaust temperature are reduced.
The oil discharge control valve group comprises a phase rod 5, a flow guide pipeline 14 is arranged on the phase rod 5, one end of the flow guide pipeline 14 can be communicated with the main oil cavity 10, and the other end of the flow guide pipeline is communicated with the oil discharge oil way 6; when the flow guide pipe 14 is isolated from the main oil chamber 10, the oil discharge oil passage 6 is isolated from the main oil chamber 10, and when the flow guide pipe 14 is communicated with the main oil chamber 10, the oil discharge oil passage 6 is communicated with the main oil chamber 10. Preferably, the flow guide pipe 14 and the valve oil cavity 12 are formed on the same structure.
In one embodiment, the oil discharge control valve bank may be a solenoid valve.
In another specific embodiment, the oil discharge control valve group further comprises a sliding sleeve 13 and a diversion driving module 3, wherein the sliding sleeve 13 is sleeved on the outer side of the phase rod 5 and is in sliding connection with the phase rod 5. Specifically, the sliding sleeve 13 may be slidably connected to a structure provided with the diversion pipe 14. The sliding sleeve 13 is provided with a diversion hole 15, and the main oil cavity 10 is communicated with a diversion pipeline 14 through the diversion hole 15. The diversion driving module 3 controls the sliding sleeve 13 to slide relative to the phase rod 5 so that the diversion pipeline 14 is isolated or communicated with the main oil cavity 10. When the device is specifically used, the relative positions of the sliding sleeve 13 and the phase rod 5 are adjusted, the size of a pore body is formed at the communication position of the diversion hole 15 and the diversion pipeline 14, and the flow of the oil discharge oil way 6 is controlled. Specifically, the diversion driving module 3 may be an electromagnetic control module.
The oil discharge control valve group further comprises a second cam 2 and a wheel body driving module for driving the second cam 2 to rotate, wherein the rotating end face of the second cam 2 is abutted against the phase rod 5, so that the phase rod 5 is driven to slide relative to the sliding sleeve 13 when the second cam 2 rotates. Specifically, the rotation speed of the second cam 2 is set according to actual needs.
The black line in fig. 5 shows the engine torque values at different engine speeds, and the area formed by the engine torque values needs to be divided into four areas, namely an area a, an area B, an area C and an area D, and each area is provided with a corresponding valve lift operating state of the valve mechanism.
Two adjustable gas distribution assemblies are arranged in each cylinder, when the engine is positioned in a low-speed high-load area, two intake valves 11 are simultaneously opened, and an oil discharge oil way 6 of a first adjustable gas distribution assembly is closed, and an oil discharge control valve of a second adjustable gas distribution assembly is opened for a preset angle. Because the knocking tendency is the most serious in a low-speed high-load area, the lift and the duration of the two intake valves 11 are synchronously changed at the moment, and specifically, the two intake valves 11 are 20-40 degrees different from each other, so that a certain vortex effect is formed, and the combustion speed is increased; meanwhile, the closing time of the intake valve 11 with long duration can be 20-40 degrees earlier than that of a symmetrical valve to form an early Miller effect, or the closing time is delayed by 20-60 degrees to form a late Miller effect, so that knocking tendency can be reduced by early and late Miller, and the early Miller effect is better.
In order to facilitate control of the intake time and the intake air amount, preferably, two adjustable air distribution assemblies are arranged in each cylinder.
Specifically, when the engine is located in a low-speed low-load region, after the first intake stroke of the intake valve 11 of one adjustable valve distribution assembly is finished, the intake stroke of the intake valve 11 of the other adjustable valve distribution assembly forms a second intake stroke, when the intake valves 11 of the two adjustable valve distribution assemblies are opened, the oil discharge control valve group opens the oil discharge oil path 6, and the intake stroke of the intake valve 11 in the closed state of the oil discharge oil path 6 is half of the intake stroke of the intake valve 11 in the opened state of the oil discharge oil path 6. The low-speed low-load adopts two-stage air intake, the total duration of the first air intake stroke and the second air intake stroke is equivalent to that of the original symmetrical air valve, and the pressure of an air intake manifold is improved mainly through the reduced lift of the air intake valve 11, so that the pumping loss is reduced; the first intake stroke forms a first turbulence energy peak value at the initial stage of the intake stroke, the second intake stroke forms a second turbulence energy peak value at the final stage of the intake stroke and is kept to the ignition moment, so that the flame propagation speed is accelerated, the maximum lift of the first intake stroke is about half of that of an original symmetrical valve, the maximum lift of the second intake stroke is about half of that of the first intake stroke, and the proportion of the two turbulence energy peak values can be adjusted by adjusting the proportion of the two lift values.
When the engine is in a high-speed low-load region, the oil discharge oil circuit 6 of the first adjustable gas distribution assembly is closed, the oil discharge control valve of the second adjustable gas distribution assembly is opened by a preset angle, and the opening time of the air inlet valve 11 of the first adjustable gas distribution assembly is earlier than that of the air inlet valve 11 of the second adjustable gas distribution assembly. Specifically, in the high-speed low-load region, one intake valve 11 is opened later than the other intake valve 11, the late opening angle is about 40-60 degrees, the vortex level is improved through the asymmetric phase of the two intake valves 11, the combustion speed is improved, and the exhaust temperature is reduced.
When the engine is positioned in a high-speed high-load area, the two adjustable air distribution assemblies are used for opening the air inlet valve 11, the oil discharge control valve group closes the oil discharge oil way 6, and the opening time of the air inlet valve 11 opened by the two adjustable air distribution assemblies is a first preset time period difference value. Specifically, in the high-speed high-load region, one intake valve 11 is opened later than the other intake valve 11, the late opening angle is about 40-60 degrees, the vortex level is improved through the asymmetric phase of the two intake valves 11, the combustion speed is improved, the exhaust temperature is reduced, the late miller effect is formed through the late closing of the second intake valve 11, and the temperature in a cylinder at the end of compression is reduced, so that the knocking level is reduced, the maximum lift of the two intake valves 11 is equivalent to that of the traditional symmetric intake valves, and therefore, the sufficient air inflow can be still kept in the high-speed high-load region, and the rated power is ensured.
The application provides an engine, which comprises a valve mechanism, wherein the valve mechanism is any valve mechanism. The application includes the valve mechanism, and the application has the technical effects as well.
