What is the Great Wall Feng Jun 6 engine and where is it produced?

4D20 is independently developed by Great Wall with a displacement of 2.0 liters. It adopts a series of advanced technologies, such as CRDI, electronic throttle, VGT, hydraulic lash adjuster, dual-mass flywheel, etc. As can be seen from the greatly increased maximum speed, the performance index obviously exceeds the original 2.5-liter and 2.8-liter INTEC series diesel engines. The engine performance has reached the international advanced level and is second to none among domestic independent brand manufacturers. The only competitor is SQR48 1A with a displacement of 1.9 liters, and Chery has not yet mass-produced it (configuration gallery word-of-mouth forum). However, 4D20 has taken the lead in key indicators such as power and torque.

Relevant information also revealed that there is a previously unknown high-performance version of 4D20 series-4D20b. Different from the standard version, the 4D20B is equipped with an independent intercooler, with a higher booster ratio and different supercharger models. The intercooler of 4D20B is air-cooled tube belt type, which is integrated in front of the radiator of the cooling pump, exhausted by the cooling fan and cooled by the oncoming wind, with good cooling effect. It can effectively reduce the intake temperature, optimize the charging efficiency and improve the engine power. It can also reduce the combustion temperature and reduce the emission of harmful substances. The smoke emission limit of 4D0B is less than 90% of the standard model 4D20, and the fuel economy performance has been improved accordingly. The specific degree of dynamic performance improvement has yet to be confirmed. In order to give full play to the powerful power of Haval H5 Sports Edition equipped with 4D20B, Great Wall only provides a 6-speed manual gearbox, which is temporarily not matched with a 5-speed automatic gearbox.

At present, in the market share of Haval series, the gasoline engine version and the diesel engine version are basically equally divided. How successful the 4D20 series with superior performance is, on the one hand, its adaptability to domestic oil products, and its cost performance is more critical.

After overcoming a series of technical problems and even security risks caused by the extremely high working temperature of supercharger, the research and development of 4D20 series was basically completed in the first half of this year. As early as a year ago, the Great Wall began the final mass production work. In order to get the best benefit, the Great Wall did not start a new stove, but was rebuilt by using existing factories and production facilities. By purchasing new production equipment such as vertical machining center and vertical milling machine, the modernization of engine production line was completed with an investment of only 65.438+0.3 billion yuan. At present, the project is implemented smoothly and will be put into production soon, and mass production will be realized before the end of this year.
