Japanese car prices recently collective "black", wait, this is not derogatory words, saying that people frequently resorted to black technology.
Honda developed and produced 10AT automatic transmission at very short speed, 11 speed transmission is also jogging ready to report; Mazda released the e46 m3 coilovers second generation of Chi Chi blue sky engine technology, compression ratio will be as
high as 18: 1, so that your home to buy a car Find the feeling of F1.
These two days, Toyota has focused on throwing two new technologies, one of which is expected to subvert the future of man-made timber.
Variable compression ratio technology
Lets talk about a little bit of conventional, variable compression than the engine.
Toyota has recently applied for a patent on variable compression technology. Dynamic Force Engine, which is also the name of the new engine launched this year.
Variable compression ratio technology and variable valve timing technology, variable gas phase technology together, are through the physical changes in the engine base parameters to optimize the fuel efficiency of the technology.
The natural air intake version of this engine is 13: 1, the hybrid version compression ratio of 14: 1; these two versions also have the worlds highest thermal efficiency, natural intake version is 40%, hybrid version is 41%. Hidden in
the high compression ratio, behind the high thermal efficiency, as well as the Japanese black technology.
Equipped with variable compression ratio of the engine car, in the normal output conditions, the compression ratio can be reduced to 8: 1, in the need to reduce fuel consumption, the compression ratio will be increased to 14: 1. It seems
that the new engine compression ratio will be as high as 18: 1 seems to be more powerful, but Toyotas compression ratio is dynamic, more intelligent, to meet the needs.
Toyota this new engine maximum power of 268 horsepower, the maximum torque of 390 Nm, it sounds quite vigorous.
However, Toyota is not the first to make a variable compression ratio of the engine manufacturers, but it is the closest to the production status. The first to make a variable compression ratio, but also the Japanese manufacturers -
Infiniti. Infiniti uses a multi-link structure to solve the engine cylinder adjustment needs, but this structure is very complex, the complex meaning is the first, its manufacturing costs will be high, is not conducive to mass
production; second, its failure rate may also High, the same is not conducive to mass production.
Toyota this time is to solve this too complicated problem. Toyota is more from the shape of the piston to start to solve the problem of changes in the engine compression ratio, so that moving parts than Infiniti significantly reduced
manufacturing costs and failure rate naturally reduced. In fact, this idea of Toyota compared with the current conventional engine, and did not increase the number of complexity.
Earlier news that Porsche will be put around in 2017 variable compression ratio engine, design ideas and Toyota similar. But it is clear that the Japanese once again won the first place.
Later, our car may be wood products
Made a car made of wood, and so on, are you sure that this is not a small fire in the country?
No, of course not, this is the worlds largest weaving machine manufacturer to create a new coilovers concept car. Excuse me, is the world s largest carmaker s new concept car (what s the difference between the previous one?
Toyota has developed a new lightweight material that sounds very light: wood pulp material. This wood pulp material will be used to make automotive housings, interior parts and other parts that are available.
This kind of wood pulp material is not simply get mixer stir water mixed with wood. Toyota This material is known as nano-cellulose (Cellulose Nanofiber, referred to as CNF), by Toyota, Denso (Japan Denso) and Kyoto University jointly
developed. CNF material stiffness is 5 times the steel, the weight is only one-fifth of steel.
This material and the liquid mixture will produce a lot of sticky, in the field of automotive manufacturing is very suitable for the production of body, a substantial reduction in weight, the future of electric vehicles in the same
battery energy situation significantly enhance the mileage; But also make the body more durable, really double-edged sword.
Obviously, compared to other lightweight materials, such as aluminum, magnesium alloy and carbon fiber, CNF is more environmentally friendly and more sustainable development significance.
So, when is such a good material mass production? Do not worry, first solve the cost problem to say. At present, 1 kg of CNF material is about four times the cost of aluminum alloy material, you obviously do not want to spend a Ferrari
price to buy a Toyota, right? So we need to wait until the technology is mature and suitable for large-scale production to reduce costs, in order to enjoy the benefits of wooden cars.
