Beijing Diesel Engine Exhibition
In order to plan for the forthcoming China Six Market, the products exhibited in this exhibition will also be based on the National Six. As the leader in the domestic engine industry, Weichai has just won the China Quality Award, the highest honor in China's quality field, on November 2nd with the “WOS Quality Management Modelâ€, and then exhibited it at the exhibition. Quality and technology in the country's six series of flagship products.
In this exhibition, Weichai exhibited WP2.3N, WP3N, WP4.6N, WP7NG, WP9H, RA428 , 6 engines that meet the national six emission standards, as well as core components and independent ECUs independently developed by Weichai. The most notable of these is the 8.8L WP9H engine independently developed by Weichai, mainly because of the bright spots of this engine.

Emission standards have been changing, and the constant pursuit of Weichai's pursuit of superior quality
China Truck Network reporter learned from the description of Weichai technicians that the reliability of WP9H has achieved the highest standard in the industry, and the technical applications of gantry cylinder block and four-valve integral cylinder head TOP-DOWN cooling are effective. The reliability of the product has been improved, and the product has been verified by the cumulative bench test in the national key laboratory for more than 15000 hours. In addition, the WP9H diesel engine oil change cycle can reach 100,000 kilometers, driving 1.8 million kilometers, equivalent to 45 rounds around the earth.

Running at an altitude of 3,500 meters does not affect the quality of Weichai
It can also be seen from the “ID card†of WP9H that the 8.8L machine parameters have the best standard of the same displacement in the industry and belong to the international advanced level. WP9H series engine power range covers 310-350Ps, which can meet the most transportation needs in the industry, and the machine can achieve 2300N.m output under special use conditions, such as mine heavy load, which is a real "tough guy".

In addition, the technicians also told the China Truck Network that the WP9H series engine will not be affected even if it is running at an altitude of 3,500 meters, which can meet the daily transportation power of tractors, trucks and dump trucks at high altitudes. demand.
New platform, high starting point, low fuel consumption data
"Look at fuel consumption, you have to use data to speak." When asked about the same displacement of the national six engine fuel consumption and the national five engine fuel consumption, the field technicians introduced: "Weichai WP9H engine equipped with Weichai independent research and development and maturity The electronically controlled high pressure common rail technology, leading the industry's 2000bar fuel injection system, the new combustion chamber and air passage matching design, make the oil and gas mixing more fully, the combustion efficiency is higher, the minimum fuel consumption rate is 185g / kWh. So the same Under the working conditions, the fuel consumption of Weichai's Guoliu engine will naturally not be high."
The modular design is reflected in the WP9H engine.
The advantages of the engine module design need not be said, but it is reflected in the WP9H engine of Weichai. This most "unusual" integrated oil filter on the WP9H engine body is different from what the reporter has seen on other diesel engines.
WP9H engine's unique oil filter
It is understood that after a large number of experimental data comparison, the filter effect of this integrated filter is comparable to the traditional machine filter effect, but the economy is far superior to the two machine filters on a traditional engine. Due to the overall lightweight and modular design, the weight of the WP9H engine is only 800KG.
WP9H engine uses Weichai's independent research and development ECU
It is worth mentioning that, unlike other engines using Bosch ECU, Weichai WP9H is equipped with its own WISE ECU. This ECU is independently developed by Weichai for many years according to domestic customer needs, based on domestic geographical environment changes and technical route adjustment. In terms of reliability, fuel economy, power, safety and after-sales support, it is more suitable for China's operating conditions.
WP9H engine two-stage diesel fine filter layout is unique
According to national regulations, it is imperative to switch the emissions of the national six. At present, some provinces have announced the implementation of the national six emission standards in advance, and the call for the “blue sky defense war†has become stronger. All relevant enterprises in the country are closely deploying the national six. . As the industry's "leaders", Weichai has already matured the national six technology reserves, and only after the regulations are implemented nationwide, the Weichai Guoliu products can be put on the market with a large number of commercial vehicles, and once again lead the market with quality and technology.
