Without transitional sequelae Maisford engine born country four

In September 2014, the first Mais Fu engine produced by JAC Navistar officially went offline, marking the official start of mass production of the Maasfu engine in the market and facing market challenges. At that time, the fourth-tier government policy voices bursts, and the full range of Mysford Engines fully meets the country's four emission policies and is born for the country.

National Four Policy Application Challenges Natural Country Four Solved

According to the China Truck Network reporter, according to the plan formulated by the relevant national ministries and commissions, the National IV policy will be implemented starting from January 1, 2011. It has been postponed three times for four years until January 1, 2015, but it has been vigorous but The unresolved Fourth National Policy has finally come to a final conclusion and it has been implemented nationwide.

The reason for this is not only that the state has declared that the oil is not up to the standard. The reporter thinks that there is still a part of the reason that the domestic engine technology is not yet mature, although at that time a number of domestic companies released engines that met the national fourth or even the fifth, but the core technology Still subject to foreign suppliers, under the monopoly of the market, many technical problems still need to be solved, far from what we thought. Simply adding EGR or SCR can solve many problems, including the engine. Many factors such as the matching of the system and components, the reset of the engine ECU, and the selection of materials are a long way to go. According to many users, the problems with the use of the national four-vehicle vehicle and a few years ago were numerous, and the reporter also learned that the phenomenon of the fake country of the fourth country was also more serious, and the national policy was repeatedly blocked.

Nowadays, the four policies for diesel vehicles have been fully implemented, but many users are adversely affected by the previous four engines. They are concerned that the upgrading of the National Three engine to the National Four engine technology is not mature enough, but hesitant to implement the four engines. Wait and see attitude. The Maasfu engine has the core of China and the United States R&D technology. In the foreign markets with higher emission standards, it has stood the test of many years and accumulated strength. When it first entered the market, it will face the standards of the National IV engine and users are completely worried about the country. The legacy problems generated by Sanshengguosi will be solved.

Adapt to China's market leading technology and strong

Due to the vast landmass and resources of our motherland and the large environmental differences in the eastern, western, southern and northern regions, many users will of course worry that foreign products will be unsatisfied in the Chinese market. Wang Yuntao, technical staff of Jianghuai Navistar Performance and Development Department, briefed the reporter: Maisford Engine has fully taken into account the domestic operating conditions at the beginning of design, including the driver’s driving habits, diversification of driving conditions and The matching of the truck platform, and after many tests, fully considered the overall economy, practicality, and reliability of the use of the engine in the entire vehicle, and strived to meet the user's various use requirements.

In response to the technical advantages of Maasfu's engines, Huang Shaoming, technical staff of the design and application department of JAC Navistar, introduced to the reporter: Maisfu Engine has a world-class component supply chain, and the 2.8L and 3.2L engines produced are highly efficient. Electronically controlled EGR system uses advanced intelligent brushless motor EGR valve, combined with Navistar's unique ultra-low coefficient of friction valve system, leading DAVNT two-cycle variable turbocharger, cross-inlet and exhaust technology and classification Combustion technology gives Maisfu engine more reliable technical support. The engine block and cylinder head adopt a new lightweight design. The weight of the whole machine is 315KG, and the minimum fuel consumption rate of the full load is only 200g/kW·h. Both the dynamic performance and the fuel saving performance strive to achieve the best level.

Huang Shaoming also said that the Maasfu 4.8L engine produced by JAC Navistar is currently the largest displacement engine with a maximum power of 140 kW and a maximum torque of 720 N·m. It is mainly used on medium and heavy trucks. Has the highest lift torque and lowest fuel efficiency in its class. Matching a high-efficiency waste-gas bypass turbocharger ensures that the engine technology maintains optimal fuel efficiency even at low speeds. The fuel system uses Bosch's high-end common rail system, rail pressure up to 1800bar, injector Bosch's most advanced nitriding process, the maximum temperature up to 450 °C (general material temperature is 300 °C), can significantly increase the auxiliary brake power. Safety, reliability, and fuel economy are the most reliable guarantees.

The Maasfu engine produced by JAC Navistar has now been widely used on JAC light trucks and medium-sized cards, and its users are highly rated. Despite being a newcomer to the domestic engine market, the market share is still low, but with the users The quality requirements for the engine have gradually increased. I believe this "newcomer" will surely come from behind, and the waves will be pushed forward by the Yangtze River.
