[Truck Home Original] As a major force in intercity transportation, mid-load trucks are favored by major logistics companies. In Australia in the southern hemisphere, a driver recently tested the 9 different models of Qingling F series mid-load trucks at one time. After understanding, I found that some of the 9 trucks tested this time have not been launched in my country. Since that's the case, let's enjoy your eyes through words.
Because you have to test drive 9 cars in one day, this test drive takes relatively short time on each car. The driver said that he could not make a detailed test drive assessment, but only gave a simple evaluation. After testing all the cars, he felt that each car felt very good to get started, and the latest four-cylinder engine left a deep impression on him.
The F series Chinese card used in this test drive uses three four-cylinder engines, with a maximum cargo weight of 10.7, 11 and 12 tons respectively. All vehicles are loaded with cargo with a maximum load weight of 80% for test drive.
Take the FRR 107-210 mid-card that uses the minimum power four-cylinder engine as an example. During the test drive, 10 pallets were placed in its cargo compartment. Although the power output is small, the power of the vehicle is still strong enough during driving. When using economic mode, the engine speed can be maintained at a speed of 1000 to 1200rpm.
The other two inline four-cylinder engines are also powerful enough, they are the FRR 110-240 model with 8 pallets and the FSR 120-240 model with 12 pallets.
● Qingling new AMT-TC technology automatic shifting is smoother
In the current truck market, automatic transmission has gradually become accepted and more popular among drivers. Therefore, the nine Qingling F series models tested this time are all automatic driving.
In fact, there are still some minor problems in the development of Qingling's automatic transmission technology, but their latest development AMT-TC unit equipped with torque converter function can improve the smoothness and accuracy of gear shifting, making gear shifting smoother.
Allison has unparalleled advantages in the automatic transmission system, so in order to achieve the automatic shifting function, Allison transmission will be installed in Qingling's latest F-series models. The F-Series model, equipped with the latest 4HK1 four-cylinder engine and transmission AMT-TC automatic shift technology, will become the leader among mid-load trucks.
● Qingling F series mid-load truck There are more than 180 models to choose from
At present, Qingling's F series has become the largest mid-load truck model in the Australian market. There are 180 models to choose from based on the total vehicle weight and gearbox form.
The total weight range of the four-cylinder F series model is 10.7 tons to 14 tons, and six-speed manual or automatic transmission can be selected. Most six-cylinder engine models offer a six-speed Qingling manual transmission or Allison fully automatic 2500 six-speed transmission.
Another exception is that the slightly heavy-loaded FVR and FVD models use ZF manual transmission or the Allison MD 3000 automatic six-speed transmission.
● The new 4HK1 and 6HK1 engines can meet the Euro VI emission standards
Today, engines of all brands around the world are developing towards large outputs of low displacement, in pursuit of lightweight, high profitability and high engine efficiency. Qingling is no exception.
The 9 cars tested this time used a 4HK1 four-cylinder engine and a 6HK1 six-cylinder engine.
The six-cylinder engine uses 6HK1 with a displacement of 7.8 liters, and there are two versions:
outputs a maximum power of 256 horsepower when the speed is 2400rpm, and the maximum output torque can reach 761Nm in the speed range of 1450 to 2400rpm;
outputs a maximum power of 296 horsepower when the speed is 2400rpm, and the maximum output torque can reach 981Nm in the speed of 1450rpm.
four-cylinder engine uses a 4HK1 with a displacement of 5.2 liters, equipped with two-stage turbocharger and intercooler , and has the following two versions:
outputs a maximum power of 207 horsepower when the speed is 2400rpm, and the maximum output torque can reach 726Nm
at 2400rpm, and the maximum output torque can reach 237 horsepower when the speed is 2400rpm, and the maximum output torque can reach 765Nm
In order to meet the emission standards, the 6HK1 engine is equipped with an EGR system using a diesel oxidation catalyst. Qingling is committed to being the only engine in the Australian market that can meet the specified emission standards by not being suitable for diesel particulate filters or SCRs.
That is to say, after using the diesel oxidation catalyst DOC, the diesel particulate regeneration process can no longer be required, because this process generally needs to be carried out under high temperature conditions, and if it does not interfere with the normal operation of the truck, it will be difficult to generate enough heat for the diesel particulate regeneration process.
In post-processing, the 4HK1 engine uses EGR technology and a diesel particle diffuser. The latest diesel particle diffusion system uses a unique fuel injector in the manifold to solve the particle regeneration problem.
has advantages in emissions, and fuel consumption is also an advantage of the 4HK1 engine. Data shows that 4HK1 can save nearly 7% of fuel compared to the same engine. This can reduce the cost of using a lot of vehicles to a certain extent.
● Postscript
The core of a good car must be the engine. Qingling’s new F series mid-load truck can be said to have done a lot on the engine. The new AMT-TC automatic shift control technology, advanced exhaust gas treatment technology, etc. all add a lot to the value of this car. Judging from the driver's test drive experience, he is still very satisfied with the Qingling F-Series card. What do you think of this car, card friends? (Text/Zuo Jie Picture/Network)
