Drive-E is a new Volvo powertrain generally named in a more efficient, more energy efficient, more environmentally friendly as the direction of development, the drive train cover two series (gas / diesel) engine and a total of eight 8-speed manual gearbox. Drive-E in the “E” contains three concepts: Efficient power (Efficient Dynamics), Electrification (reserved for the future, battery power), Environment (environment-friendly).
1 Volvo Drive-E Term analysis
Volvo Drive-E are generally named new powertrain, more efficient, more energy efficient, more environmentally friendly as the direction of development, the powertrain The system covers two series (gasoline / diesel) a total of eight engine and 8-speed manual gearbox. Drive-E in the “E” contains three concepts: Efficient power (Efficient Dynamics), Electrification (reserved for the future, battery power), Environment (environment-friendly). Drive-E powertrain innovation significance of conflictBreaking number of cylinders, displacement constraints on the performance of smaller displacement, higher performance, lower emissions, and environmental protection to achieve the perfect balance of power, but also both innovative features and intelligent electrification.
2. Volvo Drive-E engine
in the engine architecture Drive-E powertrain referred VEA (Volvo Engine Architecture), comprising a total of 8 engine, gasoline engine comprising 4 VEP (Volvo engine Petrol) and four diesel engines VED (Volvo engine diesel). It is worth mentioning that all of the above models and later will be born in this concept model, are the following three principles: the displacement of 2.0L, 4 cylinder number, all supercharged models (turbo / mechanical).
Gasoline aspect, the initial introduction of T3, T4, T5, T6 adjustment four versions, T3, T4, T5 turbo single different versions of adjustment, T6 + as a turbocharger supercharged version of the dual plenum. Drive-E series by direct injection gasoline engines, turbo / supercharged DOHC four-valve structure, the continuously variable valve timing technologies, to improve intake efficiency and fuel efficiency, improve dynamic performance . Temporarily volume production models for T5, T6 two, wherein T5 provides performance data 180kW (245PS) / 350Nm and in supercharged mode, a short burst of torque 380Nm extremum, thisOverseas models delivered on lines 60 (S60, V60, XC60); in addition, T6 matched Roots supercharger (supercharger) + turbocharger, two were in the low speed / high-speed operation, respectively, intervention, complementary short board, making this outbreak 2.0T four-cylinder engine 225kW (306PS) parameter extremes / 400Nm of.
Diesel aspect, the early launch D2, D3, D4, D5 tuning four versions, D2, D3 is set as a single turbocharger, D4, D5 dual turbo set. Drive-E series diesel engine applications i-Art intelligent injection system at the top of each injector are installed only high sensitivity sensors and a microprocessor, real-time data through the continuous monitoring of the fuel pressure and temperature, automatically adjusting fuel injection situation, to enhance fuel efficiency. The distribution model D4 now in volume production and the market, the maximum power of 133kW (181PS), peak torque up to 400Nm. But, in recent years, Volvo has not introduced the diesel version of the program, so whether on domestic or imported models, this dynamic parameters sizeable D4, and will not sell into China in recent years.
Drive-E Series engine and a motor generator reservation interface (and other electrical devices and mounting of new technologies), direct future expansion raised hybrid. In the next generation XC90, by adding plug-in hybrid electric technology such as blessing, bringing the entire powertrain performance comparable naturally aspirated V8 engine older.
3. Transmission Volvo Drive-E
as an important part of the Drive-E strategy for Volvo, Volvo selected on the gearbox, using a newly developed Aisin AW transverse 8AT gearbox. Volvo is the first scheme is fully equipped with a transverse gearbox Aisin 8AT car companies. This code AWF22 a transverse gearbox, can withstand the maximum torque of 400Nm (petrol), the ratio range up to 7.5, only 96 kg weight, compact and reliable.
It should be noted that Volvo’s new engine architecture with this transverse 8AT synchronous development, matching aspects of competitive advantage, compared to other brands DSG (dual-clutch) transmission, Volvo 8AT in size, weight, considerable performance situation, but also have stable, reliable, low maintenance cost advantages. In the Chinese market, Jeep and Land Rover brand pioneered the use of ZF (ZF) of 9AT transverse gearbox, Volvo uses crank 8AT transmission from Aisin AW, you can also win a good market in China is Volvo’s future line of products technical reputation.
In addition, Volvo Drive-E powertrain further includes an electronic speed-dependent power steering system is mounted on a part of the standard configuration Drive-E gasoline engine S60 / V60, the main function is to improve fuel economy . The system can be changed according to the speed of change in steering effort, but also with Lane Keeping Assist LKA (Lane Keeping Aid), parking assist (Park Assist Pilot), a personalized set of steering force (Personalization steering) and other functions.
4 Volvo Drive-E spatial distribution
Since the Drive-E powertrain small, modular structural characteristics, equipped with the new powertrain Volvo, space utilization of the nacelle will be relatively significantly improved. Especially between the engine and the passenger compartment will leave more space, the purpose is to equip future motor different sizes, to achieve hybrid. ?
Next to the engine itself, the structure of the motor unit has reserved the connection interface. Theoretically only a few individual parts need to be replaced on the engine body, it can be easily connected to the electric motor, to achieve hybrid.
Also in the development stage designer SPA vehicle platform, but also well prepared for the Advanced Drive-E powertrain system, such as the chassis area beneath the seats reserved for members of the battery pack space. In case of need, Volvo future new products are available in the architectural foundation Drive-E on the introduction of plug-in hybrid.
Volvo has even set aside space for rear drive motor for the new models, which could become a future direction of development of Volvo’s hybrid field. Traditional power precursor with rear-wheel motor drive, power can further enhance product performance. Of course, from the current situation, the configuration will not in large scale in the short term.
5. Volvo Drive-E future planning
The official definition of Volvo Drive-E is in the E: EfficientDynamics (Efficient power), Electrification (Electrification) and environmentally friendly (Environment), Correspondingly, a set of powertrain and vehicle matching Stage Three stages. ? The first stage: the traditional type of fuel powertrain in 2013 to market a modular 2.0T engine and eight-speed automatic transmission component. The second stage: supporting the hybrid system will be mounted on a whole new generation of XC90. The third stage: by 2020, achieve universal application and pure electric technology. The Drive-E strategy is not only to solve the upgrading of existing Volvo Powertrain, the Volvo 2020 is always “zero emissions, zero accidents” strategy component. ?
