In the end, any hybrid technology is the engine!
For all power architectures composed of internal combustion engines, batteries, and motors, including large and small range extensions, the underlying support force is still the internal combustion engine if you want better technical performance.
A good internal combustion engine offers several key advantages.
One is better work efficiency, whether it is power generation efficiency or direct drive ability, a high thermal efficiency engine can bring a better experience and lower fuel consumption.
Many people have a misunderstanding about thermal efficiency, or companies are deliberately misleading, that the highest thermal efficiency is actually the instantaneous thermal efficiency achieved within a certain range.
An internal combustion engine with a maximum thermal efficiency of 43% is not necessarily better than an internal combustion engine with a maximum thermal efficiency of 40%.
Because it also depends on the comprehensive thermal efficiency under daily work, in fact, the comprehensive thermal efficiency of many models is less than 34%, but its maximum thermal efficiency may exceed 43%.
The other is NVH, which is the abbreviation of noise, vibration and harshness, the NVH of the engine is very important, and it is the only way for enterprises to evolve and upgrade from rough to fine.
A good internal combustion engine should be less noisy, less vibrating, and more precise in sonic harshness, which can bring a better user experience.
The most important thing is that in a hybrid system, a good internal combustion engine is directly related to fuel consumption.
Many people think that in the era of electrification, there is no need for internal combustion engines, but in fact, on the contrary, the era of electrification implements the working strategy of batteries and motors to assist internal combustion engines, and more avoids the low thermal efficiency working range of internal combustion engines, which are performed by electric motors and driven by internal combustion engines in high-speed areas.
It's not that the motor isn't important, the motor is just as important, but the importance of the internal combustion engine shouldn't be discarded.
An excellent hybrid system requires both the motor and the internal combustion engine, and the two drive systems work together to do a good job in the electrification system.
Some people have been complaining about the ideal one before, and there is indeed a reason, dam12td's 1The 2T three-cylinder small displacement engine is purchased, one is backward in technical standards, the other is that NVH is really bad, the most important thing is that even the most basic quality is not well controlled, and the oil seepage problem has also appeared in a small area.
At present, they are all hybrid-specific engines, and it is true that the comprehensive thermal efficiency will be higher, because there is no need to consider the demand for low-speed torque, and the demand for power generation and high-speed operation is directly considered.
Relatively speaking, the threshold for design and manufacturing is lower.
However, as I said above, the higher the comprehensive thermal efficiency, the better the NVH internal combustion engine must be a core technical route to promote the development of hybrid technology, just like the two legs of people, not only the development of batteries, motors, but also the technology of the internal combustion engine to keep up, in order to ensure the low fuel consumption, high performance and excellent durability of the hybrid system.
After all, a hybrid model equipped with an internal combustion engine is essentially a gasoline car, and it is an act of putting the cart before the horse, not looking at the engine but only the electric motor.
