Toyota FCV release reignited the electric and pure fuel cell debate, but whatever the outcome of the debate on how to actually belong to the future of technology - they have at least ten years, the popularity of the real, as much as twenty years. So if it is a pure electric or FCV, remains a concept at this stage that noun. The first models on the list, and can only be regarded as the pioneer of small scale only. Recently, two heads of Tesla holdings, should be able to explain the problem.
Well, in this 10-20 years, in the direction the car at the end use development of energy technology, there is also controversy. We have to win most definitely the final depth of tapping the potential of energy technologies based on traditional (small-displacement turbocharged direct injection as representative), or should there be pressure to head back in hybrid technology.
The direct injection turbocharged different hybrid nature
If we just look at market penetration at this stage is clearly supercharged direct injection prevail. Volkswagen not only universal direct injection supercharged, followers and imitators lot. In contrast, hybrid, it is still only in high-end markets performed well, while the real need "to take the number of" low-end market, their market share is still limited.
An important reason for the fact direct injection supercharged high prevalence based on traditional energy sources to improve the technology. Can be achieved by a small displacement supercharger power, in the case of the same displacement of the engine power is reduced, the overall cost but more controllable. At the same time, due to the compressor may actually improve efficiency direct injection head rotor 149701-0520 +, while the supercharged low speed and high torque characteristics of the engine, but also brings good fun to drive, easy to naturally gain popularity.
Based on the foregoing, there is no change in the basis of direct injection supercharged engine works, so the engine is one of the "ERROR" more important there, which is a big difference in efficacy between different conditions - even if more advanced direct injection supercharged engine, also impossible to get a steady intake of urban and suburban fuel. In contrast, the gap between the fuel consumption can vary from two to 50% or more.
Furthermore, this technique does not solve the problem of high emissions of urban roads. The vast majority of family cars driving in town for most of the time, which causes the actual value of the supercharged direct-injection technology in energy saving and emission reduction committed - switching consumption fuel will still be around 10 liters, compared with conventional techniques do not feel the essence of the difference.
Hybrid is not the same. Essentially, the principle is concerned, hybrid revolutionized working conditions of the engine, which in theory could eliminate inefficient engine operation, and all work in efficient condition. In other words, even in congested urban driving, but also allows the engine to operate as a constant-speed driving country roads as efficiently work to achieve the suburban urban fuel consumption considerably. What is the concept? This means that an ordinary family car in congested road travel one hundred kilometers can be achieved fuel consumption of 5 liters or less, than conventional vehicles can be reduced by half. Such is the nature of change.
The direct injection supercharged hybrid does not exclude
Equivalent 1.4T 2.0L, this argument has been recognized most of the population. This is so for two reasons. One is the subsequent data supercharged engine power is indeed improved. The other is the actual performance, turbocharged direct injection low torque is strong, the effect can be achieved naturally feel 1.4T 2.0L pairs.
In fact, this feature also includes a hybrid. About Cloud bacteria before this car had been specifically discussed, namely how to deal with hybrid power. Based on the principle of hybrid we know, everyday driving, some of the energy stored in the battery inside. Then people energy demand is mainly reflected in what conditions? No doubt: the acceleration. Specific conditions include the initial speed, overtaking, and lines and so on. In this condition, the engine battery backup power and the engine can be layered to achieve dynamic consolidation. This combined forces of acceleration, no less than the supercharged direct injection. From the standpoint of implementation is also similar characteristics: a consolidation of power were not small, and the second, stronger engine low torque, the acceleration forces of sections conventional low speed even better than the direct injection of supercharging effect.
Another point not forget, turbocharged direct injection and hybrid are not mutually exclusive. That is, the hybrid can be superimposed with a turbocharged direct injection phase. Indeed increasingly hybrid supercar energy use this function to achieve a qualitative leap. For example just mentioned the BMW i8, the only 1.5T engine, but can reach four second acceleration performance, must rely on the engine battery.
Toyota hybrid's popularity depends on the change in strategy
That being the case, why at this time to permit the penetration of direct injection supercharged prevailed him? The principle is the basis of public hybrid, ie, the engine runs efficiently under (uniform, high velocity) of excess energy stored in the battery, and then when the conditions of inefficient work (congestion) released by the engine, while avoiding inefficient engine work (of course, at the same time, there is additional energy recovery braking and a range of measures) when working conditions. This sounds simple, but the implementation is very difficult.
First, a combination of wonderful institutions is required. He just has a clutch power and cutting engine power engine and combines, in fact, is the most basic, is difficult to achieve the desired effect. Currently only the world of Toyota THS II is through unique structures to achieve VTEC. ECVT not a CVT. A planetary gear set is used, and then through the auxiliary motor (NOTE: This is not used for driving the auxiliary engine is a single engine) to achieve torque transmission ratio infinitely variable. Engine power and the power of the drive motor through the transmission. The structure itself is very subtle, but more subtle is the algorithm. It is no exaggeration to say that, so far, only Toyota dominated this algorithm.
Therefore, hybrid target rests condemned Toyota hands. For the popularity of Toyota's hybrid strategy must change.
For a long time, Toyota hybrid uses for a strategy of "partial final". Even the hybrid car Prius entry level, positioning is not low (comparable to a car of class B). More hybrid technology, the main input in Lexus models. In fact, this technology in the Lexus RX, CT and other models has revealed a strong competitive advantage. However, the popularity of hybrid for more positions is the most critical.
瑞尊瑞 Camry production and sales to get a good test, able to set aside if the hybrid is no shortage of buyers. Indeed positioning Rui Zunrui Camry remains high. In fact, according to price theory, Rui Zunrui Camry 2.5L engine based on the superposition of about 105 kW / 270 Nm motor high power, the actual dynamic performance has been the equivalent Camry 3.0L. This action corresponds to 259,800 yuan a guide price, even without taking into account the conservation of energy, the price was also very impressive. But most buyers do not need such a powerful force, restricting its popularity.
From the recent news, we can feel a major change in the strategy of Toyota, which is the progressive realization of the popularization of hybrid. Toyota is located in Changshu, central Jiangsu province of China DI + was officially opened last November. The center is the sixth R & D center of Toyota in the world, is the only center of D with a test track and R abroad, with a total investment of $ 689 million. The first major project after the R & D center opened, is to achieve hybrid localization. Next will be listed in the Corolla and Ralink hybrid version is used in the location of the hybrid.
From the perspective equipped, this combination is a 1.5L hybrid. Although there is no clear information, but based on the point of the practice of Toyota hybrid view, its dynamic performance should be quite a 2.0L or 1.5T. If the price then hybrid models Corolla / Ralink according to the 2.0L price positioning, competitive advantage is self-evident. More crucially, Corolla / hybrid Ralink will not be like the previous hybrid car that is just a foil, supplement, but is likely to become its flagship car. Once this pattern is formed, which would mean the popularity of the hybrid era will officially come.
Abstract: The future of 10-20 years, become a regular at the new hybrid powered cars family protagonist must not be too suspenseful. Before this time, the car was in the mushroom cloud ad Corun analyzed and interpreted. Toyota has invested so much for so long inactive in this regard, it should be waiting for an opportunity. Once mature, Toyota ready to shelve, mean hybrid was officially opened. Toyota's action of these terms, this is the time should not be opened further. Perhaps, in 2015.
