Since the development of the Chinese logistics industry today, the benefits of shortening the transportation time and increasing the transportation efficiency have been far higher than the vehicle’s overloaded limit, which has made the high-powered engine gradually become a new industry demand. Obviously, major domestic engine manufacturers do not want to miss such business opportunities and have launched diesel engines with more than 500 hp. A "China's largest horsepower heavy truck engine dispute" is so vigorously launched!
Dongfeng Cummins: ISZ13 engine enters vehicle matching 
The Dongfeng Cummins ISZ13 engine project has been under development since 2005. It is powered by Cummins global R&D network. It is mainly designed based on the Cummins heavy-horsepower engine. The cylinder, cylinder head, crankshaft, connecting rod, camshaft, and oil pump are all compatible with Cummins. Horsepower engine design is similar.
The ISZ13 engine uses ultra-high pressure (XPI) fuel injection technology jointly developed by Cummins and Scania and has an injection pressure of 2,400 bar (typically up to 1800 bar in the industry). This technology is also used in Scania heavy trucks with 13 liters. Euro 5 and Euro 6 engines.
The engine has a net weight of 1195 kg, a maximum horsepower of 525 horsepower, a maximum torque of 2508 N•m, and an economical speed of 1100 to 1400 rpm. The large torque brings greater power output to the ISZ13 engine. When applied to a vehicle, it is easier to accelerate or climb.
In terms of emissions, it uses Cummins Emissions Processing System (CES) selective catalytic reduction technology to meet the country's fourth-generation emissions, and has a smooth upgrade capability to European V and US EPA 2010 and above regulations.
In addition, the cumulative operating time of this engine has reached 30,000 hours, and more than 20,000 hours of effective bench tests. Trucks equipped with the Dongfeng Cummins ISZ13 engine have passed over 6 million kilometers of road mileage in different road conditions in China, the United States, and Australia. Experienced reliability tests such as 20% super oil, 20% overpressure, and 150% overspeed, whose reliability is beyond any doubt.
China National Heavy Duty Truck: Launches 540 Ma Liman Technology Engine 
In the 2014 China National Heavy Duty Truck Group Business Meeting tasting session, the 540-horsepower MC13 engine became the focus of attention. This so-called commercial vehicle engine with the largest horsepower in the country won a good reputation for its high power, reliability and fuel economy, which is more than that of the MC11 engine.
The MC13 engine from the German Man D26 has a net weight of 975 kg, a displacement of 12.419 litres, a maximum horsepower of 540 horses, a maximum torque of 2500 N•m, and a maximum torque of 1050 to 1350 rpm. The engine is equipped with Bosch common rail system, B10 life up to 1.5 million kilometers, up to the national five emission standards, applicable to long-haul cargo tractors. Because of its superior speed-increasing performance, it is able to better exert its fuel economy in high-speed freight transportation, and it can be described as the “heart†of the high-power horsepower under the Mantech technology platform.
There are two major differences between the MC13 and other engines: First, the cylinder material is made of vermicular cast iron, which gives it higher tensile strength and fatigue resistance, and its strength can be improved by 75 compared with the conventional gray cast iron on the market. %. Secondly, the design of the middle combined gear of the air compressor adopts the scissors-type coaxial gear combination, which can eliminate the backlash of the gears, avoid the impact of the air compressor when working, and reduce the noise.
Weichai: WP13 series engine released 
At the 2015 Weichai Power Commercial Vehicle Engine Technology Conference, Weichai released the WP13 series engine. The WP13 engine uses Bosch's high-pressure common rail technology, with a net weight of 1001 kg, a displacement of 12.54 liters, a maximum torque of 2,500 N•m, and a maximum torque of 1050 to 1,350 revolutions per minute, featuring low-speed high-torque.
What is commendable is that this 550-horsepower WP13 engine can be started directly at -15°C without auxiliary measures, and can be started smoothly at -40°C with preheating. The vehicle can perform well in extremely cold conditions with an average failure interval exceeding 250,000. Km, BI0 life of up to 1.2 million kilometers.
The WP13 engine features a dry cylinder liner and a frame-type body design with a single-use feature. The double-layer integrated high-strength dry cylinder liner makes the engine's structure simpler. The 1.18 cylinder center distance and bore ratio make the whole body stronger and run more smoothly. This also ensures the high attendance of the engine.
In the choice of emission technology route, WP13 engine adopts SCR exhaust treatment technology with lower requirements on the explosion pressure, which is beneficial to improve the life and reliability of the engine, and can meet the Euro 6 emission standards.
Xichai: New 13-liter 500-horsepower diesel engine on display
In December 2015, FAW Jiefang exhibited a 500-hp new 13-liter CA6DM3 diesel engine at its annual business conference. The engine is made of vermicular cast iron processed by a special process. The piston is of all-steel technology with a net weight of 1050 kg and a maximum torque of 2300 Nm. It uses the integrated FCRI high-pressure common rail fuel system from FAW and the fuel injection pressure can reach 2000 bar.
The CA6DM3 engine is designed and developed based on the CA6DM2 engine and is part of the Xichai Aowei M platform. It inherits the excellent structural design of the M series engine and has high dynamics, reliability and economy. This also allows the CA6DM3 engine to have a better torque output to meet the main road transportation needs.
Therefore, the engine's B10 life is 1.5 million kilometers, and its reliability is extremely high. Even if ordinary mineral oil is used, it can be replaced with 40,000 kilometers of oil.
The exhaust gas treatment of the CA6DM3 engine adopts the SCR technology, and the use of a self-developed gas-fed urea system has advantages such as low cost and unfavorable clogging of the urea pump. The system has been applied to a number of liberated models.
Yuchai United Power: 580 hp engine turned out 
In 2016, Yuchai United Power introduced the five new YC6K1358-50 diesel engines. This engine is based on the world's top DD13/15, and has been independently researched and developed over six years. It integrates the latest in the world today. The technological achievements, with more than 30 technological invention patents, not only has the power and reliability of diesel engines, but also has the comfort of a gasoline engine.
The engine has a displacement of 12.939 liters. Bosch common rail technology has a maximum torque of 2550 N•m. It has the characteristics of strong power, low fuel consumption, and good emissions. It is very suitable for the current high-volume large displacement high- Demand for vehicles.
In addition, the YC6K1358-50 engine uses reliability growth technology for the first time in the world, significantly increasing the service life of the engine. The life of B10 is 1.6 million kilometers, and the emission level can reach the national 5th and above standards. The technical quality can be combined with the latest mass production in Europe. The engine is comparable.
The high-profile launch of the Yuchai United Power 580 hp engine shows its emphasis and urgency on the high-powered engine market, and the slogan of “the largest torque, the largest displacement, and the largest horsepower of heavy-duty diesel engines†also makes this your slogan. The “battle of the strongest horses†that chased after me once again pushed the wave.
View: the overall trend of China's commercial vehicle engines long way to go <br> <br> high-speed standard contained, logistics companies and users to pursue more attendance and transport efficiency, high-powered engine for high speed logistics to enhance the benefits will be enormous. At the moment when the domestic engine has just entered the era of 500+, over 700 horsepower engines have already become commonplace in Europe, and efforts have been made to break through the 800-horsepower mark. Such peak momentum is not known when it will appear in China.
