Brief introduction of WEVB (exhaust valve braking) technology of Weichai Power; introduction of WEVB structure. WEVB auxiliary braking system EVB“EVB "is the abbreviation of English exhaust valve braking, which was first adopted by Wei Chai in China. This technology comes from MAN company in Germany, and Chai Wei bought this patent from MAN company and applied it to WD6 15 automobile engine. With the improvement of safety awareness, more and more trucks are equipped with exhaust braking devices. This traditional exhaust braking device uses butterfly valve to close the exhaust passage, so that the piston is subjected to the back pressure of gas during the exhaust stroke, which prevents the engine from running and produces braking effect, thus achieving the purpose of controlling the vehicle speed. Necessity of applying WEVB Due to the further development of heavy-duty vehicles, higher requirements are put forward for braking power. When heavy trucks and other large vehicles are driving downhill on a long ramp, they will accelerate down the ramp under the action of gravity. At this point, if there is no external resistance moment to offset this gravity, the vehicle will be out of control. If the car further develops in the direction of heavy load, it puts forward higher requirements for braking force. When heavy trucks and other large vehicles are driving downhill on a long ramp, they will accelerate down the ramp under the action of gravity. At this point, if there is no external resistance moment to offset this gravity, the vehicle will be out of control. If it is diffuse, build it. , will, build. . Yes, using the brake system on a long slope will damage the brake system and cause serious accidents. In order to ensure the safe driving of vehicles and enhance the market competitiveness of products, Wei Chai decided to equip all automobile engines with exhaust valve braking devices to further improve the braking power of the whole vehicle. In Europe and America, the auxiliary braking of heavy-duty diesel engines has become a mandatory safety regulation and must be equipped. In order to ensure the safe driving of vehicles and enhance the market competitiveness of products, Wei Chai decided to equip all automobile engines with exhaust valve braking devices to further improve the braking power of the whole vehicle. In Europe and America, the auxiliary braking of heavy-duty diesel engines has become a mandatory safety regulation and must be equipped. The working principle of WEVB auxiliary braking system is based on the traditional butterfly valve exhaust braking device. When the butterfly throttle valve is closed, the diesel engine works like a compressor under the drag of the gravity of the car. The exhaust pressure in the exhaust pipe can be increased enough that the exhaust valve of the cylinder whose piston approaches the bottom dead center in the intake stroke is pushed by the piston of the adjacent cylinder. The pressure wave generated by waste gas is open, which is verified by experiments. At present, this phenomenon will occur in all butterfly valve braking structures. WEVB auxiliary braking system uses the phenomenon that the exhaust valve is automatically opened by pressure wave during braking, and improves the braking efficiency of the engine by keeping the exhaust valve open during engine braking. Brief introduction to the working process of WEVB auxiliary braking system When the exhaust valve is opened by pressure wave, the exhaust valve braking mechanism will prevent the opened exhaust valve from closing (keep the stroke of 1-2mm or so). In this way, in the compression stroke, a part of compressed air leaks from the cylinder. Even after the piston reaches the top dead center, the exhaust valve is still open. In this way, the compressed air expands into the exhaust pipe through the gap of the exhaust valve, which greatly reduces the downward movement speed of the piston in the expansion stroke and prevents the compression work from driving the engine to do work again. At the beginning of the exhaust stroke, the exhaust valve is completely opened by the movement of the rocker arm, the oil unloading hole on the rocker arm of the exhaust valve is opened, the lubricating oil is ejected, and the slider assembly returns. Repeat the above process to increase the braking power of the diesel engine. The main structural feature of WEVB auxiliary braking system is 1. The structural advantages of the original WD6 15 Euro2 diesel engine are retained. 2.2 oil supply. WEVB braking system adopts the combination of external oil supply pipeline and internal oil supply channel, and the oil is led out from the auxiliary oil channel of the engine body, then goes to the cylinder head of the sixth cylinder through the external oil pipe, and then is connected with the cylinder head through the short pipe. 3. All external pipes are arranged on one side of the air inlet pipe, and the temperature on this side is relatively low, which can effectively prevent fire accidents caused by leakage. 4. The special machine body, cylinder head and valve rocker arm seat are internally provided with oil conveying channels. 5. Add a set of actuators on the rocker arm of the exhaust valve to control the movement of the exhaust valve. 6. Add supporting arm, oil seal adjusting bolt assembly and WEVB system oil supply pipeline and other parts. 7. The height of the cylinder head cover is increased by 32mm. What should be paid attention to when using WEVB auxiliary braking system? 8? After the diesel engine adopts WEVB system, in order to ensure the reliability of all related components on the diesel engine, it is necessary to adopt a new structure of exhaust brake valve. 8? In order to prevent diesel engine failure caused by improper matching of exhaust brake valve in the main engine plant, Wei Chai will adopt exhaust brake valve? 8? In addition, after adopting WEVB system, the adjustment method of exhaust valve clearance of diesel engine is different from the original one. See relevant technical documents provided by Wei Chai for details. 8? 9 Application scope of Wei Chai automobile engine with WEVB braking system Development achievements of WEVB system test-bed for heavy trucks, various special vehicles and luxury buses.

Test conditions: Assemble the diesel engines with WEVB system and without WEVB system on the same heavy-duty vehicle in turn, and assemble the diesel engines of the comparative test system on the same long downhill section in turn under a certain gear on the same heavy-duty vehicle. Comparative test of the same long downhill section under the same gear. The comparative test results of driving time on long downhill sections show that the road on the south slope of the mountain is 3km 4km long. The travel time from the top to the bottom of the slope is10' 45 ÷/8'15 ÷13'10 ÷. 1 1' 15÷ Use the brake without braking/8 times, and brake for 3 times/brake 13 times.
