1. Unique valve lift technology
Honda is the first to develop the engine valve lifting technology, which is simple in structure and clear in thinking. It is called i-VTEC, known as Accord, Odyssey, Platinum Core and Song Shitu. This technology is used uniformly, and its working principle is huge on the camshaft.
However, it has only two stages of adjustment, which is better than Valvetronic invented by BMW.
2. Unique parallel-axis automatic transmission technology
Honda's parallel-axis automatic transmission is easy to understand, but its essence is to convert the synchronous shift fork into hydraulic pressure based on manual transmission, and install multiple clutches at the original synchronous sleeve position like the fork control mode of DSG double clutch. That's like the founder of double clutch.
nowadays, the popular dual clutch is "hub-and-axle" type. Whether it is DSG or domestic dual clutch, Honda will not take the ordinary road. If it changes its own parallel shaft transmission, it will become a dual clutch transmission. Moreover, first of all, it is very personal to use a motorcycle instead of a car.
Other cars don't have dual clutches with hydraulic torque converters, but Honda's belt invented the first manufacturer of dual clutch transmissions using hydraulic torque converters in the world. The picture below shows Honda's 8DCT transmission, and its two input shafts are quite different from DSG's "sleeve shaft".
3. Unique variable capacity technology.
generally speaking, the working volume (i.e. displacement) of each cylinder of an automobile engine is exactly the same, and the regular reciprocating motion of the piston can be said to be the most basic rule. However, Honda broke this "iron law" with new patented technology, making the engine's emissions per cylinder the same. Assuming a 2.L 4-cylinder engine, the size of each cylinder should be 5cc. According to the number of cylinders, there are only four situations: 5cc, 1cc, 15cc and 2cc. ?
The variable displacement technology invented by Honda, according to the change of crankshaft radius, each cylinder piston can have different strokes, so each cylinder runs with different "displacements", and there are at most 15 different combinations, in other words, the same 2.L cylinder engine. I know that it is very difficult to change the crankshaft radius in the dynamic mode of high-speed rotation, but Honda has done it. That is, a 2.L displacement engine, Honda can play 15 different displacement changes. This is unmatched by any automobile manufacturer in the world at present. It is said that Honda has not published information about this technology. This technology will soon be used in Honda Accord, Geshitu and other models. Three technologies that only Honda has.
