Later, with the rise of the new energy industry, BYD has the inherent advantages of battery resources, so BYD gradually gave up research and development on internal combustion engines and began to focus on three electric technologies. If there is a miracle in this world, then his other name must be hard work. Yes, BYD who worked hard has won. In the field of new energy technology, BYD has indeed won, breaking the traditional burning shackles with brand new power technology. Realize curve overtaking in new energy technology. Although the technical attainments of Sanden are already well established, BYD has never stopped its research and development in power technology. The plug-in hybrid technology has been used in China for many years, but the best power technology is still BYD and BYD Tang DM. The performance has not been surpassed by that hybrid model. Constantly pursuing and exploring in power has become BYD's mission.
The sky has paid off, and BYD, who is keen on new energy, has once again achieved a breakthrough. This time it is not a battery, not a motor, or a turbocharged engine. This time it is a 1.5L high-efficiency self-priming engine for Snap Cloud-plug-in hybrids. In this era of turbines everywhere, BYD once again chose to make innovations and breakthroughs, combining self-priming engines with batteries to form the most efficient power combination. This 1.5L self-priming power has an ultra-high thermal efficiency of 43% and is the world's most efficient mass-produced gasoline engine. This engine is not only super fuel-efficient, but can easily meet the "National VI b" emission standards.
, a 1.5L high-efficiency engine dedicated to plug-in hybrids, is able to achieve such a high thermal efficiency. It is inseparable from its numerous black technologies. It has an ultra-high compression ratio of 15.5; it increases the stroke-bore ratio. ; Adopt Atkinson cycle; Equipped with EGR exhaust gas recirculation system; Optimize the engine control system for high thermal efficiency targets.
At the same time, BYD has enabled the engine split cooling technology for the first time on this engine. Through the temperature control of the cylinder head and cylinder block, the cylinder head and cylinder block can be accurately cooled on demand, so that the cylinder head and cylinder block can be located. The best working temperature improves engine efficiency, shortens the time of warm-up process by 15%-20%, and reduces fuel consumption and emissions during warm-up process. In addition, because this engine is specifically used for plug-in hybrid models, the traditional front-end wheel train of the engine is cancelled and the accessories are electrified, which further reduces losses and improves efficiency.
Although the maximum power of this 1.5L engine on a single internal combustion engine is only 81kw and the maximum torque is 135NM, this data seems to have no bright spots, but when used in a hybrid module, its value will be truly reflected. With the help of the high motor Torque, this set of plug-in hybrid power can not only respond quickly and transmit plenty of power to the wheels at the start, but also minimize the fuel consumption during low-speed sports, and even when the battery is running low. The fuel consumption is perfectly controlled at about 4 liters.
If this set of power is used in a compact car with a small volume and weight, the fuel consumption performance will definitely be very good. I believe that at that time, a tank of oil running 1,200 kilometers will no longer be a miracle. I have to say that BYD is a very strange existence among many domestic car companies. His sales are not high, his reputation is not very good, his car logo is complained, and his technology is misunderstood. He has never argued, he will not follow the trend, and he will not do what others do. He can always lead the trend in the field of cross-generation technology. Even the self-priming power abandoned by the major car companies can play new tricks in his hands. BYD will be the true pioneer of domestic future automotive technology.
