Description

  The present invention relates to a drive system capable of realizing an internal combustion engine variable valve, and more particularly to a modular variable valve drive system used in a 4-cylinder internal combustion engine and modularized.

  With the rapid development of the world economy, energy and environmental issues have already become important issues affecting the sustainable development of the economy. The internal combustion engine is the most widely used power machine in the world, and consumes a large amount of fuel oil every year and discharges a large amount of harmful gas and particulate matter. It becomes urgent. Variable valve technology is also of great interest from domestic and foreign internal combustion engine research institutions and companies due to its potential to improve the performance aspects of internal combustion engines. In addition to this, with the rapid increase in possession of internal combustion engines, the lives and property losses of people due to traffic accidents increase year by year, the safety of vehicles is increasingly valued by people, and auxiliary braking devices are increasingly used in more countries. It is adopted as one of the necessary accessories for vehicles. However, in many of the current auxiliary braking devices such as the eddy current deceleration module and the hydraulic deceleration module, the braking component easily overheats during the operation process, and the braking efficiency is reduced too quickly, so that the braking ability can be controlled. There is a problem that the vehicle is lowered and the vehicle at the time of braking flows easily, and the brake system occupies a limited vehicle space. The engine's auxiliary braking device can avoid these problems. In the current engine auxiliary braking device, the braking efficiency of the 720 ° C A / cycle decompression type auxiliary braking device is the highest, but this device still has the problem that the braking horsepower is relatively small. The need for energy saving, toxic emission reduction, and vehicle safety, which are imminent, are adjusted independently between valve cycles, cylinders, and valve operating parameters (valve opening timing, maximum lift, opening duration). It is driven to develop in the direction possible, ie towards the fully variable valve drive system. Regarding the above problems, there is an urgent need to develop a variable valve drive system that simultaneously satisfies the internal combustion engine 720 ° C./cycle drive mode and the 360 ° C. A / cycle compressor braking mode.

  Currently, many of the variable valve drive systems that have been put into practical use hold the valve cam and use a mechanical structure. Mainly 1) Camshafts such as TOYOTA (registered trademark) VVT system, BMW (registered trademark) Vanos system, etc. It is divided into a fading type, 2) a stepwise variable valve lift type such as a Honda (registered trademark) VTEC system, and 3) a continuous variable valve lift type such as a BMW Valvetronic system or a Hyundai (registered trademark) CVVL system. These systems adjust the opening / closing timing and / or the maximum stroke of each cylinder valve of the internal combustion engine by controlling the intermediate transmission mechanism.

  Compared to a variable valve drive system with a cam, a system without a cam can realize a more flexible valve event, and at the same time, the structure is complicated, the cost is high, and the aspects such as reliability, durability and valve thermal expansion compensation control Need to study deeper. These systems mainly include two types: electromagnetic and electrohydraulic. Further improvements are necessary in terms of electromagnetic system motion control and valve lift adjustment. Compared to mechanical and electromagnetic systems, the electro-hydraulic system is the most potential variable valve drive system with higher valve adjustment flexibility, higher power density, layout flexibility, etc. . The system mainly includes two types, a common rail lubrication type and a cam lubrication type.

  The common rail lubrication system removes the valve cam and controls the opening / closing timing of the valve and the maximum stroke by controlling the open / close state of the solenoid valve and the pressure of the hydraulic oil in the accumulator. Ford, Lucas, etc. have studied this, but it is still necessary to study deeply in terms of system cost, response speed, occupied space, and the like. As the number of cylinders, single cylinder valves, and rotational speed of an internal combustion engine increase, the system further includes 1) the volume of the common rail tube is huge, making it difficult to arrange the space. There is a problem that the total cost of the system is relatively high and the overall cost of the system is relatively high because of the relatively high solenoid valve cost determined by current solenoid valve materials and processing techniques. These problems make it relatively difficult to put a conventional common rail oil supply type variable hydraulic valve drive system into practical use.

  Combining the advantages of mechanical and common rail lubrication systems, cam lubrication systems are of great interest from researchers and manufacturers, such as the Fiat® Multiair system, the ABB® VCM system, and the like. These systems replace the accumulator with a cam-plunger type lubricator, and because the occupied space is small, it is possible to realize simultaneous adjustment of valve opening and closing timing and stroke, but it is also improved in the following two aspects The first is the relatively large quantity of lubricators and solenoid valves required for the system, and the overall cost of the system tends to be high; the second is the adjustable range of valve operation In addition, under the restriction of the control device, independent adjustment between the valve opening / closing timing and the stroke cannot be realized, and the 360 ° A / cycle valve operation process required in the auxiliary braking mode of the internal combustion engine cannot be realized.

  For these problems of cam lubrication systems, a cam lubrication electrohydraulic valve drive system has been developed that uses a cam-plunger lubrication system to eliminate common rail tubes and reduce the number of lubricators. The space arrangement became easier. However, the system still has the following two problems to be solved: 1) The number of solenoid valves required for the system is excessive and the system cost is relatively high. 2) Adjustable range of valve drive Is limited by cam-plunger lubrication rhythm, exhaust valve double opening event cannot be realized, 720 ° C / cycle internal combustion engine required in 360 ° A / cycle compressor braking mode A valve event cannot be realized. This limited the expansion of the system functionality.

  With respect to the problems existing in cam-lubricated electrohydraulic valve drive systems, a dual-mode fully variable valve drive system has been developed that reduces the quantity of solenoid valves through the use of drive-brake circulators and mode converters, and At the same time, it meets the variable valve events required by the driving and braking modes of the internal combustion engine. However, the system still has several problems to be solved: 1) The 2-position 5-way valve used by the system must be switched in different situations with different pressure differentials at each oil port, The pressure difference change situation of the oil port is extremely complicated, and as the rotational speed increases, the shorter the response time of the 2-position 5-way valve, the higher the flow velocity is required. These requirements are the structure of the 2-position 5-way valve. 2) In the internal combustion engine drive mode, the system is unable to close the valve in the refueling stage of the refueling system, which means that the internal combustion engine idling and low and medium operating conditions of the system These operating conditions are just normal operating conditions for city vehicles, and the internal combustion engine operating conditions under these operating conditions greatly determine the fuel consumption and emission conditions during actual driving of the vehicle. 3) The structure of the drive-brake circulator is complex, the number of external oil piping is relatively large, the system process is reduced, the system cost and the difficulty of the arrangement increase; 4) between the components of the system; The functionality is interdependent and for different application requirements, the placement of multiple components and the entire system has to be changed, limiting the application scope of the system.

  Regarding the problems existing in cam oil supply type electrohydraulic valve drive system and dual-mode fully variable valve drive system, multi-function intensive variable valve drive system has been developed in recent years, simplifying the structure of solenoid valve and driving internal combustion engine The valve was closed in the refueling stage under the mode. However, this system still has the following two problems to be solved: 1) The structure of the cycle selector is complicated, the number of external oil piping is relatively large, the process of the system is reduced, the cost of the system and Increased difficulty of deployment; 2) The functions between the components of the system are interdependent, and it is necessary to change the layout of multiple components and the entire system for different application requirements, limiting the application range of the system.

  Therefore, the present invention achieves the purpose of the variable valve event required in the driving and braking modes of the internal combustion engine with an oil valve and an electromagnetic valve having a simple structure through the design of the stage-limited module. Integrated the variable valve technology and auxiliary braking technology of the internal combustion engine into one, while at the same time greatly simplifying the system structure and achieving the cost reduction objective of the system; 2) simplifying the structure of system critical components such as stage-limited modules, Reduce the number of external oil pipes, improve the technology of parts, reduce the cost of the system; 3) Independently function each component of the system through the adoption of a modular design method, Select the system and other components and the overall system layout To achieve a further objective of which need not be, and enhance adaptability to model systems, to extend the system application range; and an object thereof is finally enhanced market acceptability of the system.

  In this specific embodiment, the stage limiting module 2 and the mode selection module 22 are designed by taking a 1-2-4-3 type four-cylinder internal combustion engine as an example. For the stage limiting module 2 of the 1-3-4-2 type four-cylinder internal combustion engine, the opening angle of each oil port cross section of the stage limiting module mandrel 2n is adjusted based on the corresponding stage limiting module 2 or braking. For an internal combustion engine having a mode, an oil line connection target between the stage limiting module 2 and the mode selection module 22 is changed, and for an internal combustion engine having no braking mode, the oil between the stage limiting module 2 and the valve driving module of each cylinder is changed. It is only necessary to change the line connection target, and a detailed description thereof is omitted here.

In particular, Table 1 is a schematic communication relationship that does not consider the actual operating conditions of a specific internal combustion engine, and in an actual application, the data in the table must be corrected based on the actual requirements of the internal combustion engine. Note that. For the continuously variable valve event internal combustion engine, the line indirectly connected to the oil tank 8 is deleted.

  According to the demand for opening and closing the valve of the internal combustion engine in the braking mode, the naturally aspirated internal combustion engine using the exhaust-exhaust-valve braking mode by the intake valve causes the valve drive system to be dead in a state where braking is necessary. By opening the intake valve near the point and discharging the compressed air in the cylinder along the intake passage, the compressed air does not work on the piston when the piston descends; exhausts near the bottom dead center By opening the valve and drawing air into the cylinder from the exhaust path, the negative work of the piston compressed air increases when the piston rises. Turbine-supercharged or naturally aspirated internal combustion engines that use the intake-exhaust valve exhaust braking mode with an intake valve have a valve drive system that opens the exhaust valve near top dead center when braking is required. By discharging the compressed air in the cylinder along the exhaust path, the compressed air does not work on the piston when the piston descends; the intake valve is opened near the bottom dead center and the air is taken into the intake path. By sucking into the cylinder, the negative work of piston compressed air increases when the piston rises.

In particular, Table 4 shows a general communication relationship that does not consider the actual operating state of a specific internal combustion engine, and the data in the table must be corrected based on the actual demand of the internal combustion engine in an actual application. Note that. For the continuously variable valve event internal combustion engine, the line indirectly connected to the oil tank 8 is deleted.
