Now the most talked about on the Internet is that various car companies are converting new energy tracks, is there still a way out for fuel vehicles? And the No. 92 gasoline has broken 8 blocks 5, and even approached 9 pieces. Can we still buy fuel vehicles?
It is true that many manufacturers are transforming into new energy trams. BYD stopped producing fuel vehicles in April, and Wei, a subsidiary of the Great Wall, has also transformed from a luxury SUV in China into a new generation of smart cars to make new energy power.
"Fuel vehicles have no way out, the development of internal combustion engine is a dead end", this kind of remarks, but in the view of Meow Brother, the internal combustion engine still has a chance, but this opportunity is more subtle, there are still some manufacturers obsessed with the internal combustion engine technology improvement and research and development.
Volkswagen will not develop new engines, but will upgrade its current power
Previously, Volkswagen's boss said that "no new fuel engines will be developed in the follow-up", and the Volkswagen Group has determined the future direction of pure electric vehicles.
However, as the world's second largest automobile giant, in the long period of time when there is no complete refusal to let fuel vehicles be sold, it will certainly not easily give up the market for fuel vehicles, so volkswagen group has not completely abandoned the internal combustion engine.
Because for a long time before, the Volkswagen Group developed enough internal combustion engines to upgrade on these internal combustion engines.
At present, Volkswagen's latest engine is the 1.5T EA211 EVO engine, which has been confirmed to be installed on the new Sagittarius according to relevant reports.
This 1.5T turbocharged engine adds only 2 kilowatts to the previous 1.4T with a high compression ratio miller cycle with a compression ratio of 12.5:1.
Before the traditional turbo engine in order to avoid knocking, are the use of low compression ratio, but volkswagen 1.5T engine such a high compression ratio, is not to drink 98 oil?
At the same time, it has also upgraded from 200 bar direct injection of the EA211 to 350 bar, and adopted a 5-hole injector to improve atomization performance. It can be seen that Volkswagen is only improving the power of the internal combustion engine on the existing basis.
Second, Mazda uses amazing compression combustion technology to die on pure fuel power
Unlike Volkswagen, which directly uses the latest existing technology to gradually improve and improve the details. Mazda put its own unique "spark plug controlled compression technology" thermal efficiency, theoretically mentioned 50%.
It is the SKYACTIVE-X2.0 engine of Axela, the Chuangchi Blue Sky naturally aspirated engine, in order to compress more air, in fact, also added a mechanical supercharger.
It is only under special working conditions that the supercharging is realized. Only in the case of compression combustion is mechanical pressure, usually or naturally inhaled.
Thanks to spark plug-controlled compression technology, Mazda's engine has a staggering compression ratio of 15:1. The higher the compression ratio, the more fully the combustion of the fuel is converted into kinetic energy, without wasting every drop of oil.
It also adds a 700-pa in-cylinder direct injection, a 10-hole injector nozzle, and a 24-volt micromix system as a supplement. So this engine is really full of technology and can currently be rated as one of the most advanced internal combustion engines.
The powertrain has a maximum power of 180 horsepower, which may not be as powerful as some high-power 1.5T engines, but its comprehensive fuel consumption per 100 kilometers is only 5.2 liters.
Third, Toyota has to continue to do it in order to save fuel, in order to hybridize
Toyota mainly uses Atkinson cycle technology and electronically controlled timing variable system technology, while carrying out various optimizations of internal combustion engines.
The hybrid version of the 2.0 L and 2.5L engines both has a thermal efficiency of 41%, while the pure fuel version also achieves a thermal efficiency of 40%.
In fact, in order to meet the emission standards, Toyota can develop turbocharged engines with the same power, and the main reason why Toyota can make consumers accept is that Toyota cars save fuel.
But toyota if it develops turbocharged engines at the same power, it is not necessarily more fuel-efficient than naturally aspirated, and most turbocharged engines are fueled with 95 gasoline.
In this era of "95 full and ruined", Toyota will certainly not do this. Whether it is a 2.0L and 2.5L pure fuel model, or a hybrid model, Toyota's car can eat No. 92 coarse grain.
summary
Judging from the future trend, pure internal combustion engines have indeed been sentenced to probation.
When all car brands are developing and producing pure electric vehicles, the future will definitely slowly turn to pure electric.
But in some specific environments, pure electric vehicles are not easy to use, of course, this takes time and technology to solve.
Problems such as fast battery charging, actual mileage and charging facilities cannot be completed overnight.
Then in this period of time still needs an internal combustion engine to make a transition, and in order to make the tram mileage anxiety, most car companies still need to install an internal combustion engine on the tram, which is why the domestic plug-in hybrid is so good. So the fuel car is not dead, just slowly fading.
