In the era of fuel vehicles, those top-level engines, the old car mystery is like a treasure.
Basically, the car brands have their own signature engines, such as the German one, Volkswagen's EA888, BMW's B48, Mercedes-Benz's M274, which is a product of the past few years, in the past few years, various car companies are making efforts to large-displacement self-priming engines, various V8, V12, V16 engines.
In terms of Japanese brands, the signature is hybrid technology, various Atkinson cycles, and self-priming engines with high thermal efficiency, which are unique technologies of Japanese manufacturers. However, Japanese brands also have large-displacement self-priming engines, various V6 and V8 engines, and first-line Japanese brands have them.
Many people don't understand, why car companies want to develop 8-cylinder or even 16-cylinder engines, in fact, this is the helplessness of car companies, in the case of turbocharging technology is not mature enough at that time, stacking displacement, is the only way to improve power performance, improve the smooth operation, for in-line engines, 4 cylinders are the most basic number of cylinders to keep running smoothly, and for the V-shaped arrangement of the engine, one side of the 4 V8 engine, in order to ensure better running stability, so in order to enhance the quietness and comfort of high-end models, Engines with a large displacement to improve power performance are an inevitable choice.
For large-displacement self-priming engines, the power reserve, low torque, continuous acceleration ability, no need to downshift and overtake when cruising at low revs, and roar when igniting all fascinate fans.
However, with the continuous maturity of turbocharging technology, large-displacement self-priming engines have gradually withdrawn from the historical stage, and small-displacement turbocharged engines have become the mainstream, but whether it is V8, V12 such as large-displacement self-priming, or 2.0T, 1.5T such as small-displacement turbocharged engines. In fact, it is inevitable that some stubborn diseases of the internal combustion engine.
The low torque of the gasoline internal combustion engine, the noise problem of high speed, the low thermal efficiency of daily driving, the carbon deposit problem during long-term use, and the smoothness problem caused by the matching with the gearbox. You look at the car companies, for hundreds of years are committed to solving these problems, for this car companies have thought of countless ideas, including CVT gearbox, plus 48V mild hybrid, with audio sound waves to counteract noise, 10,000 kilometers of maintenance, to the mileage to add fuel additives, etc., but so far, these problems have not been completely solved.
However, after the appearance of the motor, all the problems were solved.
In terms of ride, even if it is a top-of-the-line V12 engine with a top-of-the-line 8AT gearbox, its ride cannot be compared with hundreds of thousands of trams.
In terms of efficiency, the thermal efficiency of the top internal combustion engine is only 45%, which is still a specific working condition, just like the spire of the pyramid, it is good to have a thermal efficiency of 20% when driving in urban areas, and the efficiency of the electric motor can easily exceed 90%.
In terms of noise, even if the engine noise is made of thick soundproof cotton, no matter how good the balance shaft and floor pads are, there is still vibration and noise transmitted to the car, and the running sound of the motor is very small, and the quietness wins.
Carbon deposits? Inexistent. Lifespan issues? The internal combustion engine is carefully maintained once a year, and it is inevitable that there will be oil leakage and oil burning, while the motor can be more stable and have a longer life without any maintenance.
Then you say, although the motor as a driving method, it is indeed stronger than the internal combustion engine, but the power battery is immature, it is true, but you can choose range extender and plug-in hybrid, why is it an electric vehicle when it comes to new energy? Plug-in hybrid and range extender, aren't they also new energy? Isn't it also a motor drive? Although they also have internal combustion engines, the role and function of internal combustion engines are greatly diminished, so it is much easier to optimize accordingly.
Although many people do not quite recognize new energy vehicles, but new energy vehicles to replace fuel vehicles, electric motors to replace internal combustion engines as the main driving mode will be a historical inevitability, the penetration rate of new energy vehicles has exceeded 50%, the era of internal combustion engines has ended.
