Compared with foreign car companies, China car companies developed late and have a weak foundation, so in the era of fuel vehicles, there has never been an amazing engine.
After the advent of the new energy era, Toyota has always been the winner in the hybrid field, although China overtook the curve and did quite well in electric vehicles, which is quite a "big brother" style.
"There are only two kinds of hybrids in the world, one is Toyota hybrid, and the other is other hybrids". As long as hybrid technology is mentioned, this sentence will be borrowed repeatedly.
However, in recent years, independent brands have also begun to increase research and development efforts, and there are also some quite good powertrains. For example, the recently popular BYD DM-i technology, or lemon DHT and so on.
In fact, in addition to these, there is another brand whose hybrid technology is no less than Toyota's, but because it is too "technical man", most people ignore the brand's technology-the global power architecture of Chery 4.0 era, that is, Kunpeng Power.
It is not too late for Chery to study the engine field. It began to study engine technology as early as 24 years ago. Up to now, Chery has applied for more than 2 1000 patents and authorized more than 1300 patents. Kun Peng's motivation is produced under this background.
The goal of Kunpeng Power is to cover all professional power solutions in the current and future mainstream power forms, so there are specific solutions in fuel, hybrid power and even hydrogen power.
For example, Kunpeng DHT hybrid technology, the world's first full-function hybrid technology, the first China brand dual-motor drive, nine working modes, 1 1 combined gear, can bring super-smooth driving experience through TSD dual-shaft drive.
In terms of efficiency, Kunpeng DHT can realize that the average efficiency of electric drive is more than 90% under NEDC working condition, the highest transmission efficiency is more than 97.6%, and the fuel saving rate is more than 50% under low power mode. Its pure electric total sound pressure level is only 75 decibels.
Like the Tiggo 8 plus PHEV equipped with Kunpeng DHT, the zero-speed acceleration will enter 5 seconds after the hybrid four-wheel drive system with front and rear motors is integrated. In the state of insufficient power, the fuel consumption per 100 kilometers is also less than 5L, the cruising range of pure electric vehicles exceeds 100 kilometers, and the comprehensive fuel consumption per 100 kilometers is about1L. That is to say, it is not a problem for Tiggo 8 plus PHEV to run 1000 km with full oil and electricity.
In terms of fuel power, the maximum power of Chery Kunpeng 2.0TGDI engine can reach 187kW, the peak torque is 390Nm, and the most important thing is that the thermal efficiency can reach 4 1%.
If you search for the keyword "4 1% thermal efficiency", you will find that there must be "the best engine in the world" in the related words. This "best engine in the world" generally refers to the 2.5L engine on the Toyota Camry hybrid version, and its thermal efficiency is 4 1%.
At present, the thermal efficiency of mass-produced engines is generally between 37%-4 1%, which means that Kunpeng 2.0TGDI engine has reached the world leading level.
Chery is still further improving the thermal efficiency of the engine, and it is expected to develop an engine with a thermal efficiency of 45% by 2030. At that time, perhaps the most famous names in the world will give way.
