Among Ward's top 1 power sources this year, hybrid motors account for three seats, including Mercedes-Benz 3.T+48V and FCA 3.6L+48V, which shows that fuel consumption and low emissions really strangle automobile manufacturers. On the other hand, this seemingly eclectic scheme is now favored by more and more OEMs. Compared with new energy products, it is more like "living in the present".
As a genuine hybrid, "Made in Honda" has entered TOP for two consecutive years. 1. And this year, there is no Toyota "making trouble". Honda, which was once robbed by its old rivals, finally has a big day. Honda's 2.L+iMMD system has now developed to the third generation, adhering to the tradition of "patching" of Japanese products. The third generation technology only made some upgrades and optimizations on the basis of the second generation technology, and it has created the engine with the second highest thermal efficiency at present, and won an award by the way.
details determine success or failure
There is no denying that this 2.L+iMMD was an excellent work from the beginning, and it was born in the background of the Toyota THS system, but the most wonderful and inspiring thing is that Honda bypassed Toyota's technical patents and created a set of technology engraved with the Honda logo.
But then things got on the right track. Honda started to do some minor upgrades and optimizations on the engine, which is probably familiar to you, because the Toyota 2.5L engine with the same high thermal efficiency also comes from details optimization. Japanese manufacturers are very good at blowing such assembly numbers, such as improving the inlet angle, strengthening the tumble ratio, or making a fuss about the angle between intake and exhaust, or using their brains on the valve coating, and then getting the available thermal efficiency data.
Honda's third-generation 2.L+iMMD system, which is such a type of film, is still a self-priming engine+dual motors, with a fixed scale ratio gearbox. Some details have changed, such as increasing the compression ratio by .5, the circulation speed of EGR exhaust gas recirculation valve, and slight deformation of the intake port, strengthening the tumble ratio, and finer details, such as mirror polishing of the intake valve and sodium-filled exhaust valve, which sounds a little & %￥*& …………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………
You should know that the thermal efficiency of Toyota's hybrid system only reaches 41% on the premise of adopting 2.5L direct injection technology, while Honda only uses 2.L multipoint injection engine, which has reached a similar level. It is only slightly dramatic that the Accord equipped with the third-generation iMMD system has a slightly higher fuel consumption than the second-generation works, and God knows what is going on.
About overtaking in corners
But this story tells us that Rome was not built in a day. Even the hybrid technology itself is a process of gradual development. For example, the light mixing technology that European and American manufacturers love to use, the fuel machine is solid, and only then will they think of using the motor to make the energy consumption lower, instead of putting the cart before the horse. The fuel machine technology is just so-so, but let the motor and battery make up for the shortcomings. For example, some plug-in hybrid products are a real mix, and it seems that they have become a force with the so-called 1-kilometer energy consumption and cruising range.
you've never heard of these manufacturers shouting about overtaking in corners, but they're playing a competitive game of "You're better than me, and I'm better than you". Japanese manufacturers may be very careful, just as they focus on details, but they are unambiguous about the technology itself, especially the engine technology, just like a toy.
It is worth noting that even Korean brands that have been looked down upon by the domestic market have occupied two seats in the Top Ten Power of Ward. The modern 1.6T engine has been gradually recognized by the judges, and his pure electric system has also been recognized internationally. So even overtaking in a corner seems to be not so easy.
[ Summary] Some people may say that there are many stories about Honda in the past two years. Indeed, in the past two years, Honda's engine has always been the darling of the media, and its colorful stories have helped public opinion from time to time, thus giving public opinion a sense of existence. The question is, even there are many kinds of mistakes, which do you prefer, the technical blank mistakes brought by taking shortcuts or the immature mistakes brought by facing technology directly?
