With the introduction of the “Made in China 2025†plan this year by the Ministry of Industry and Information Technology, this “Industry 4.0†plan, known as the Chinese version, will also bring new changes to the Chinese economy. Recently, in the “Made in China 2025†detailed edition of the Ministry of Industry and Information Technology, the “application of diesel engines to passenger cars†was clearly stated. After seeing this news, the first thing that came to mind was the arrival of Chuntian, a domestic diesel car, and a diesel pickup truck. In the future will also enter the fast lane of development.
In recent years, as long as we mention pickup trucks, everyone's common feelings are the various unfair “treatments†experienced by domestic pickup trucks, especially restricted pickups, forced scrapping and so on. However, when we talk about diesel pickups and gasoline pickups which are better, everyone's common point is that diesel pickups are good. Diesel pickups have won the hearts of domestic pickup customers because of their low fuel costs, sufficient power, and solid diesel engines.
At present, the type of domestic diesel pickup engine is still relatively single. Among the diesel pickup trucks, the engine that we talked about most is the 493 series engine of Isuzu Technology. Although major engine factories have made changes and upgrades to this type of God Machine, after all, this engine is The history has been born for more than 30 years, and its technical performance is still slightly behind. However, with the continuous advancement of technology and the growing number of domestic diesel engines, some domestic pickup trucks also carry some high-end diesel engines.
First mentioned, high-end diesel engines may all be very curious, the quality of domestic diesel is so bad, foreign high-end diesel engines in the country can adapt to it? But actually some domestic pickup is indeed carrying some high-end diesel engines, and these diesel engines There is also a very good performance.
Foton Cummins ISF2.8 Diesel Engine
Cummins Inc. is a global advanced power equipment manufacturer that designs, manufactures and distributes engines and related technologies including fuel systems, control systems, air handling, filtration systems, exhaust systems and power systems. Cummins engines are also widely used in heavy-duty trucks, medium trucks, passenger cars, RVs, light commercial vehicles, pickup trucks, and other off-road equipment. Foton Cummins was established in March 2008 and was officially mass-produced in June 2009. Beijing Foton Cummins Engine Co., Ltd. is a diesel engine manufacturer jointly established by Cummins Inc. and Beiqi Foton Motor Co., Ltd. at a ratio of 50:50. It mainly produces ISF series 2.8L and 3.8L inline four-cylinder high-pressure direct injection type. Diesel engines.
The Cummins ISF2.8 engine is a light diesel engine first launched by Cummins in China. It features power rake, low operating cost, reliable engine performance, and environmentally friendly cleaning and low noise. This engine can provide 120kW power and 360N·m torque, which has obvious advantages compared to other 2.8L engines.
Cummins ISF2.8 engine is relatively light compared to other displacement 2.8L engine, the engine weight is only 215kg, 12% lower than the same type of diesel engine. At the same time, Cummins ISF2.8 adopts standardized parts and products with a high degree of modularity, which not only minimizes the failure rate but also maintains simple and reliable product quality and long maintenance intervals, making it a truly 500,000 km-class power brand. Guaranteed high-end products.
The Isuzu 4JK1 4JK1 engine is produced by Jiangxi Isuzu. It is a product that has been upgraded several times on the basis of the original Isuzu 4JA1. This engine has the characteristics of longer life and higher reliability.
The 4JK1 uses a VGS (Variable Geometry System) variable area turbocharger. By changing the cross-sectional area of ​​the exhaust gas entering the turbine inlet, the turbo lag phenomenon is reduced, the linear output of the power is guaranteed, and the engine life can also be extended. At the same time, it also uses cast aluminum alloy cylinder heads and aluminum alloy pistons. Cast iron cylinders adopt high-frequency quenching processing technology, so that the overall strength guaranteed can also reduce the weight.
In addition, Isuzu 4JK1 also uses electric high pressure common rail, DOHC overhead dual camshaft four valve gas distribution system, formal chain transmission mechanism, and water-cooled EGR exhaust gas recirculation system.
In terms of parameter performance, the 4JK1 engine also has a significant advantage in terms of vehicle power and maximum torque compared to other domestic 2.5L engines. This engine can provide 100kW at relatively low speeds and 320N·m of torque.
Nanchang Jiangling JX4D24 engine X4D24 diesel engine is derived from the Ford PUMA engine, although the engine displacement is only 2.4L, but the engine's performance parameters are very good. JX4D24 adopts dual overhead camshaft and 16-valve gas distribution mechanism. This structure has exceeded the SOHC8 valve structure commonly used in domestic commercial vehicle diesel engines. At the same time, the cylinder head of the JX4D24 is made of AISi10Mg (silicon-magnesium-aluminum-alloy) material and weighs only 13KG, while the connecting rod is made of forging technology, and its lightweight design ensures its strength at the same time.
This engine adopts technologies such as supercharged intercooling, four-valve, ERG valve, high-pressure common rail, and electronically controlled fuel injection, which can meet Euro IV standards. However, because the JX4D24 is an improvement on the Ford PUMA engine technology, the improved engine is only equipped with an ordinary turbocharger and does not use the original variable-section engine. However, the engine is still relying on high quality parts suppliers, so that this engine has a very high reputation in the industry.
In terms of engine parameter performance, the JX4D24 engine displacement is only 2.4L, but it can provide 92kW of power and 310N·m of torque. This kind of data has a great advantage compared to other domestic engines of the same type.
The introduction of high-end diesel engines is undoubtedly an expansion of the performance and types of domestic diesel engines. At the same time, it is also an enhancement to the domestic diesel engine technology. The introduction of new technologies can promote the continuous development of domestic engines. In the coming “Industry 4.0†era, it is believed that there will be more high-end diesel engines, which will inevitably bring more new opportunities for diesel pickup trucks.
