On June 7th, Dongfeng Liu Qi Commercial Vehicle Brand Day, not only the brand strategy of "New Lapras" was released, but also the tractor version 3.0 of Lapras was officially listed.
The exterior of this car was designed by European designer marc deschamps. Compared with the old model, the new model has been further polished and upgraded in overall appearance. The drag coefficient of cab is only 0.527, and the comprehensive fuel consumption can be reduced by 4%.

As a high-end heavy truck, fuel saving is an essential quality. Of course, saving fuel can't just depend on the cab to reduce the drag coefficient. The most important thing is to look at the engine performance. Lapras version 3.0 tractor can be equipped with Dongfeng Cummins Z 14 national six diesel engine, which not only saves fuel effectively, but also is efficient and reliable.
Maximum output of 600 horsepower? Five measures to save fuel consumption
Dongfeng Cummins Z 14 engine displacement 13.5L, output power covering 480-600 HP, and maximum torque up to 2750 Nm. Moreover, when the speed reaches 900 rpm, this engine can output a large torque of 2,500 Nm, which makes the Lapras version 3.0 tractor start more easily and climb more powerfully.
In terms of fuel economy, this Z 14 adopts five measures to save fuel consumption: first, the low-friction power cylinder adopts a low-new piston-connecting rod mechanism to effectively reduce fuel consumption; The second is to ensure the best air intake efficiency through an efficient supercharger system; Third, scientific camshaft design and optimized control strategy; Fourthly, the new bowl-shaped activity design of DCEC is adopted to effectively improve the thermal efficiency; Fifth, the small piezoresistive double thermostat reduces the air pressure resistance of the thermostat. These five measures, combined with the low wind resistance cab of Lapras version 3.0 tractor, can effectively reduce the fuel consumption cost of customers.

In addition, the Z 14 engine has also effectively reduced its own weight. Through modular design, overhead camshaft, plastic oil pan, cylinder body integration, double-layer simplified hub, single-layer gear and other lightweight designs, the dead weight of the engine is reduced by 500 kg compared with the national five power products. This means that the Lapras version 3.0 tractor equipped with Z 14 engine can pull 500 Jin more goods in one trip, which will help users to increase their income.
Smarter and more reliable? Remote calibration and upgrade save effort.
Besides the upgrade of "hard power" such as stronger power, less fuel consumption and lighter self-weight, the upgrade of "soft power" of Dongfeng Cummins Z 14 engine is also remarkable. Standard "Smart Brain 2.0" realizes the perfect integration of engine and aftertreatment, improves the reliability of the system, and makes customers feel more at ease and more at ease when using the car.
This Z 14 engine realizes intelligent analysis and intelligent management of vehicle+engine big data through "artificial intelligence+big data", so that the vehicle can achieve the best operating efficiency. The first is the function of remote calibration and upgrade. The engine control module is upgraded by remote network transmission, which saves time and effort, and is safe and reliable. Compared with the traditional mode in the past, the remote mode enables customers to upgrade their software without entering the station, shortens the time for customers to upgrade their software from 1-2 days to 5 minutes, and does not delay attendance, which can improve vehicle attendance.

Secondly, it is the function of preventive health check and preventive maintenance. Every engine in Z 14 will establish a digital health cloud file to provide care for it throughout its life cycle. Through remote fault diagnosis based on big data, it can realize fault early warning and guide users to operate, reduce the probability of major faults, nip in the bud and improve vehicle attendance.
Finally, the intelligent diagnosis system for all service stations can realize fast and accurate fault diagnosis and solve problems. At the same time, Dongfeng Cummins established a digital management center. Through the application of big data, it can fully meet the daily management needs of the fleet, such as driving habits and fuel consumption, and cooperate with the fully upgraded Dongfeng Cummins after-sales service system of National Sixth to better support the fleet's efficient attendance.
