The domestic tablet computer industry has ushered in the spring weather, a variety of brands emerge one after another, manufacturers in order to be able to occupy a place in the market, the fierce competition has forced manufacturers to do their best. The competition in the Chinese flat-panel market is already in full swing. What about the domestic light-duty card industry? In fact, fierce competition from opponents in the light-card world is everywhere. With the stricter enforcement of the National IV regulations, the maturity of the IV technology of the mainstream light truck manufacturers has become a key factor in the new round of market competition. Among them, the two most popular high-end light trucks are the Jiangling Kai Rui 800 and Foton Aoling CTX. The former is the flagship product of the traditional high-end light truck overlord and the latter is the high-end light truck rookie.
Engine PK, Ford PUMA vs. Cummins Light Truck As a vehicle commonly used for short-distance logistics distribution, efficient, fast, and low cost are kings. However, the basis for this decision is the engine that has the heart of a car. The JX4D24 diesel engine on the Kerui 800 is derived from Ford Puma legendary power. It has a long history and mature technology. The 2.4L displacement can produce 90kW of power and the power is 37.5kW/L. The power is high and the fuel consumption is low. Every drop of oil is used on the blade. Aoling CTX carries the world's first ISF3.8L light power and is the latest product developed by Cummins Europe R&D Center. It uses the latest generation of Cummins turbocharger system to achieve a power rating of 33 kilowatts/liter and a maximum power rating of 115kW.
In contrast, the Kai Rui 800's maximum power slightly inferior to the Austrian Bell CTX, but the Kai Rui 800's better power, more fuel-efficient, from this view between the two light Kabozhong. But what needs to be taken into consideration is the long history of Ford Puma Power, because the newly developed engines are not as good as the number of repairable points or the reliability that has long been tested for many years. This round, Kai Rui 800 slightly prevails.
Comparison of power matching, the engine's left-right and right-arm transmission can be described as the engine's left and right arms, its quality directly affects the engine output power utilization. At present, the domestic high-end light trucks generally use five-speed transmissions, and the Kai Rui 800 matches the German Getra six-speed transmission. This MYY6S transmission is an all-aluminum structure with a state-of-the-art three-cone synchronizer, which improves the smoothness of the shift and also allows the Kerui 800 to be more accurately classified in various operating conditions. Heavy-duty start, climbing, acceleration, and high-speed driving are more fuel-efficient. Aoling CTX adopts ZF-optimized transmission, which can bring power to full use and save fuel consumption. The use of double-cone synchronizer technology enables the synchronizer to have a large capacity, light and clear shifting, and drastic reduction in transmission noise. Comfortable operation. Obviously, the Kai Rui 800 Triple Cone Synchronizer has advantages over the Olympic Bell CTX. In addition, compared with Fukuda, which was established in 1996, Jiangling, which was established in 1968, has its own unique advantages in brand accumulation and after-sales service.
State IV technology showdown, EGR against SCR
At present, there are two mainstream exhaust gas treatment solutions in the domestic automobile market. One is Exhaust Gas Recirculation Technology (EGR), a technology for the treatment of particulates produced by the combustion of fuels through particle traps or particulate catalytic converters. The other is the flue gas denitration technology (SCR), a technology that uses a urea solution to treat the nitrogen oxides in the exhaust gas through the use of selective catalytic reduction of the catalyst. Although the two different technologies share the same goal, it is very good to distinguish between the best and the poorest. First of all, the SCR technology content is not as high as EGR. SCR only needs to add a system of urea reducing agent on the basis of the engine. EGR does not need to add anything. Second, the use of SCR technology requires the regular addition of urea solutions to vehicles, which is undoubtedly an expenditure, and EGR technology should be no such troubles.
In contrast, EGR technology is more peace of mind and more economical. This is also the reason why domestic EGR technology is more widely used. Let's take a look again. The application of EGR technology in the Kerui 800 and the SCR technology of the Aoling CTX are better than they are at a glance. This round of the Kai Rui 800 is even better.
Overall, the Jiangling Kai Rui 800 is superior to Futian Aoling CTX in energy-saving and power-matching. Of course, the light trucks produced by Foton Motor in the short period of 18 years after its establishment have such a performance, which is also commendable. Just had to say: "Ginger is still old and spicy."
