In recent years, the upsurge of electric vehicles is entering the reshuffle stage with the decline of subsidies, and with the continuous improvement of global energy conservation and emission reduction policy requirements, major automobile manufacturers are introducing more hybrid vehicles. In fact, when it comes to the hybrid field, you can't avoid Toyota. Since the Prius, the global sales volume of Toyota hybrid vehicles has exceeded 6.5438+0.5 million.
In China, FAW Toyota is the first joint venture to realize the introduction and localization of hybrid technology. As early as 2005, FAW Toyota took the lead in introducing the Prius into China. In the following 15 years, with the domestic production of hybrid technology and the improvement of reputation, the hybrid family of FAW Toyota became stronger and stronger, and the price was more close to the people. Nowadays, the FAW-Toyota hybrid family has a more resounding name-the twin-engine family, including the new Corolla twin-engine for compact cars, the AVALON twin-engine for mid-size cars, the new RAV4 twin-engine for compact SUVs and the high-end MVP Wilfa twin-engine imported and sold in FAW-Toyota. In the future, more models will be equipped with dual-engine technology.
Up to now, the sales volume of FAW-Toyota hybrid vehicles has exceeded 320,000, surpassing another Toyota joint venture in China, GAC Toyota (280,000) and imported brand Lexus (300,000). At the same time, the proportion of sales of FAW-Toyota hybrid models is gradually increasing. By July this year, the sales of hybrid vehicles had accounted for 65,438+05.2% of the total sales.
In recent years, with more and more hybrid vehicles entering the China market, ordinary consumers know little about hybrid technology, but it is only a scratch. In fact, although they are all called hybrid technology, there are also great differences in technology among major manufacturers. Take FAW-Toyota dual-engine hybrid technology as an example, there are still many unknown knowledge points. Only by understanding these can we really understand? "Double engine".
1 and "double engine" are more advanced series-parallel hybrid power combinations.
"Shuangqing" is actually the Chinese name of Toyota's hybrid technology. Its core advantage is Toyota's famous THS-II system, which is called "Toyota? Half-breed? System-II ",that is, Toyota's second-generation hybrid system.
Different from Nissan's e-Power adopting series hybrid system, Honda's IMA and BYD's DM adopting parallel hybrid system, THS-II system of FAW Toyota Shuangqing is a more advanced hybrid combination mode. Through the cutting-edge technologies such as power distribution device and composite energy management, the energy-saving advantages of series hybrid power system and the acceleration advantages of parallel hybrid power system are absorbed, and through the continuous optimization of drive system, power generation system and control system, sufficient power is provided, and at the same time, more fuel is saved and emission is reduced.
Toyota's hybrid technology has accumulated more than 20 years of technology and has been upgraded many times, which is unparalleled in the field of hybrid technology in the world, so that there has always been a saying in the automobile industry that there are only two kinds of hybrid technologies in the world, one is Toyota and the other is others.
2. The technical advantage of dual engines is that they are smarter and more efficient.
Faw-Toyota dual-engine technology has obvious advantages. Compared with the general hybrid power system, the "motor" in the dual-engine hybrid power system is not an auxiliary device, it can be used for starting and accelerating the vehicle alone, which is equivalent to the interaction of two sets of power, so it is called "dual-engine".
How do twin engines work? FAW-Toyota's dual-engine hybrid system is very intelligent. It can intelligently combine and give full play to the respective advantages of engine and motor according to different working conditions such as vehicle starting, driving, acceleration and deceleration, so as to achieve both driving pleasure and environmental protection performance.
When the vehicle does not need the engine to provide high power, part of the engine power will be used to generate electricity and stored in the battery. Moreover, the kinetic energy reduced in the process of vehicle deceleration and braking will also be converted into electrical energy by the system and stored in the battery, that is, energy recovery. This is the source of "electricity" in the dual-engine power technology. Make full use of the electric energy stored in the battery as the driving force in the driving process of the vehicle, which not only reduces the fuel consumption, but also improves the power. This is also the advantage of Toyota Shuangqing's hybrid technology compared with Honda and other car companies.
Especially after a long period of low-speed driving, the battery is in a feeding state, and Toyota's engine will charge the battery while driving the vehicle forward, while Honda's i-MMD hybrid system must first completely convert the power of the engine into electric energy, and then drive the vehicle forward by the motor. One more program will inevitably reduce efficiency.
3. Planetary gear is a unique secret of Shuangqing.
The unique stunt of dual-engine hybrid is the E-CVT transmission specially installed on dual-engine models. Different from the mechanical structure of the traditional CVT transmission, the E-CVT transmission is an electromechanical integrated power output and continuous transmission device, which adopts planetary gears and other designs to realize power splitting, and planetary gears are also the essence of the exclusive secret.
The exclusive patent "planetary gear" adopted by FAW Toyota Shuangqing is completely black technology. The transmission of power and the conversion of oil and electricity depend on planetary gears. From low speed to high speed area, from urban area to expressway, all scenes can maintain high efficiency. Moreover, because the planetary gears abandon the transmission, the weight and volume of the power system are reduced, and the design of the whole vehicle is more compact.
It is worth noting that planetary gear is not only a high-tech part, but also represents the operating logic of a hybrid technology system. In the relatively perfect concept of hybrid power theory, planetary gear is an unavoidable part. As the originator of global hybrid power, Toyota Shuangqing, which took the lead in completing the design of planetary gears, has been continuously improved under a more mature theoretical framework, which has left the latecomers behind.
Limited by the advanced power distribution and patent of Toyota planetary gears, other manufacturers either increase or decrease the processing of planetary gears to develop their own hybrid technology. Therefore, the universal hybrid technology is the power distribution mode of "two sets of planetary gears+two motors", which is called "full hybrid". Honda's i-MMD hybrid system only removes the planetary gear mechanism and directly switches the output power between the engine and the motor, which is also a last resort.
4. The quietness of the dual-engine vehicle is better than that of the fuel vehicle.
Dual-engine models have two power systems, adding engines and motors. Will driving be noisy? This is a question that many consumers will have. In fact, the engine and motor in the FAW-Toyota dual engine cooperate very tacitly, which can realize the seamless switching between the two kinds of power, thus ensuring the quiet space in the car under various working conditions.
When driving in EV electric mode, the engine stops working and the car is very quiet. In terms of engine work, FAW-Toyota dual-engine models use sound-absorbing and sound-insulating materials in many parts to reduce engine noise and road noise entering the room, which is not only super quiet when driving at low speed, but also better than traditional gasoline vehicles when driving at high speed.
Twin-engine cars have lower fuel consumption than other brands of hybrid cars.
Take the Corolla Twin Engine as an example. The hybrid system equipped with 1.8l naturally aspirated engine and motor has a comprehensive fuel consumption as low as 4L per 100 kilometers, which is the lowest among all brands of hybrid vehicles at present.
To carry the Honda third generation? Take the Accord-Sharp hybrid of i-MMD dual-motor hybrid system as an example, its comprehensive fuel consumption per 100 kilometers is 4.2L, which is slightly higher than that of Toyota twin-engine models. You know, the master overreached, and the gap of 0. 1 is a complete victory. Compared with the same class fuel vehicle, the fuel consumption of Corolla dual-engine 4L can travel about twice the distance with the same amount of gasoline, and the number of trips to the gas station will be reduced by half, saving time and money.
6. In addition to saving fuel, twin-engine models are more fun to drive.
While having ultra-low fuel consumption, the power performance of FAW-Toyota twin engines is equally outstanding. The fuel engine with abundant power and the motor with extremely strong instantaneous explosive power bring strong power performance comparable to higher-level displacement.
Take the Corolla twin-engine as an example, its 1.8L engine adopts Atkinson cycle, which is a form of internal combustion engine that mainly pursues high efficiency. The maximum power is 72kW, the maximum torque is142n m, and the driving motor power is 53kW, so the final comprehensive power of the system is 90kW. In daily driving, the most common acceleration range of 20km/h-50km/h, the dual-engine model only needs 3. 1 s, far exceeding the fuel engine model of the same class.
7. Don't worry about the safety of the battery of the dual-engine system.
Some brands of hybrid models have had leakage problems, but dual-engine models do not need to worry about battery safety at all. The hybrid battery in FAW Toyota "Double Engine" has the function of self-protection, and the running state of the battery can be monitored in real time through the hybrid ECU. When the car is impacted by the outside world or enters an abnormal driving state, the battery collision induction system will immediately cut off the high-voltage power supply and discharge through the motor, thus resolutely putting an end to accidents such as electric leakage, fire and explosion. This is the protection of FAW-Toyota Double Engine for all drivers, and it is also the embodiment of the most social responsibility.
In addition, the Ni-MH battery in the dual engine can not only withstand high temperature, but also withstand the low temperature test of tens of degrees below zero, which can ensure stable performance even if it is baked with open flame and frozen in extreme cold. Therefore, in most areas of China, whether it is a high-temperature stove city or a frozen and cold mountain area, the dual-generation battery is universal and will not be disturbed by climate and temperature.
8. Global150,000 users have witnessed the reliability of twin-engine cars.
Toyota's hybrid technology was tested as early as 1997 with the listing of Prius, and its reputation of super fuel saving, easy driving and good reliability has continued to this day.
There is a real case about the reliability of Toyota twin-engine technology to share. In Vancouver, Canada, a man named Andrew? Grant's taxi driver drives a Prius with a long mileage 150 Wan Li. The car was still in good condition when it was gloriously retired, and the oil money saved could almost buy a brand-new Prius.
It is worth noting that the FAW-Toyota twin-engine models currently on sale are all from Toyota's world-leading TNGA architecture, which has been fully upgraded in terms of styling, performance, power and safety, and adheres to QDR production standards to ensure pure Toyota quality.
In fact, in more than 20 years of reliability verification, with the growth of Toyota twin-engine models, it has been verified by various climates and road conditions around the world. Toyota's twin-engine models have not experienced any major failures and reliability problems so far, and are called "unbreakable Toyota". At present, the global sales volume of Toyota hybrid vehicles is 6.5438+0.5 million, which is enough to illustrate its reliability.
9. The maintenance of a twin-engine car is the same as that of a fuel car.
No need. Compared with traditional gasoline vehicles, FAW Toyota dual-engine vehicles have a complete set of electric drive systems, but this does not mean that the maintenance cost has also increased. The electric drive system is maintenance-free for life, and there is no need to replace the battery pack or separately maintain the components of the electric drive system, such as E-CVT gearbox and motor. Maintenance is exactly the same as ordinary vehicles, and there is no difference in cost.
Consumers don't have to worry about battery life. The Ni-MH battery used in Toyota's twin-engine motor has the same service life as the vehicle. Although the battery is repeatedly used by the discharger, it will not be fully charged or exhausted, and the battery can maintain a long life in such a shallow charging and discharging environment. In order to reassure consumers, FAW Toyota has provided a warranty of 8 years and 200,000 kilometers for the dual-engine battery pack, which basically covers the service life of the vehicle.
10 and twin-engine models are equivalent to fuel vehicles.
The price of hybrid models different from other brands is 65,438+0-20,000 yuan higher than that of ordinary models. Since FAW Toyota 2065,438+05 realized the domestic production of dual-engine vehicles, the price of dual-engine vehicles has been greatly reduced, which is basically equivalent to the price of fuel vehicles. Take 202 1 corolla twin-engine as an example, the starting price is 135800 yuan, which is basically the same as the price of the same class fuel vehicle, which is also the reason why the demand for FAW Toyota twin-engine vehicles exceeds the supply.
In fact, the quality of FAW Toyota's twin-engine models is no different from that of traditional fuel vehicles, and it can get more protection in service. Judging from the sales of various models of Shuangqing family at present, they are more and more welcomed by the market.
Judging from the sales volume of FAW-Toyota during the period of1-July this year, the sales volume of the two-engine models in the Corolla family is close to 14%, while the hybrid models in the RAV4 Room Rong and the Asian Dragon AVALON account for a larger proportion, reaching 18.28% and 32. 12% respectively. In terms of services, FAW Toyota deeply practices the full-service chain services such as the "exclusive butler" plan, covering the whole life cycle of consumers from buying a car, maintaining a car and changing cars. , bring peace of mind, peace of mind and security to the quality service experience, and let users enjoy the added value beyond the product itself.
Through the popularization of the above knowledge, we have a better understanding of FAW Toyota's "double engine". Starting from Prius in 2005, FAW Toyota completed the brand and reputation accumulation of hybrid technology in 15, which made hybrid technology take root in China. It is believed that with more domestic vehicles equipped with dual-engine technology, dual-engine technology will be truly popularized in China, opening a brand-new dual-engine era for FAW Toyota.
