Roewe D7 DMH
Model introduction.
The engine and the motor complement each other:
From the drive data, it can be seen that the hybrid system is positioned as a plug-in hybrid system, and its effect is not inferior to that of the 48V mild hybrid system. The all-new DMH super hybrid system used in the car combines the engine with the electric motor. Compared with pure fuel vehicles, its power tuning is not inferior or even more powerful. The new power composition allows the engine to achieve better emissions and fuel economy, while the electric motor in the hybrid system compensates for the power disadvantage.
Significant power performance:
One of the biggest advantages of the Roewe D7 DMH is that it has highly integrated power components, which are small in size and light in weight, which can provide more surging power output. The DMH super hybrid system is equipped with 1The 5L hybrid engine adopts a number of high-efficiency and fast-burning technologies, such as high-tumble airway technology, combustion system matching optimization, deep Atkinson cycle and external cooling EGR technology, etc., and finally achieves an industry-leading thermal efficiency of 43%. In addition, the matching of intelligent and efficient hybrid gearboxes also makes the mechanical transmission efficiency reach 985%, helping users achieve the demand for both surging power and excellent fuel economy.
Free switching of drive modes:
The new generation DMH super hybrid system can freely switch the drive mode according to the vehicle speed and driving state, which is driven by the electric motor at low speed, driven by the motor auxiliary engine at medium speed, and switched to the engine drive mode at high speed, and the power system can be powered by deceleration. Not only is it functionally complete and the data parameters are superior, but the system is more complex than the conventional 48V hybrid system from a structural point of view. SAIC has spared no effort in technological innovation to develop this new generation of DMH super hybrid system.
