In the 4S store, there will be some evaluation videos, more or less will mention some of the technology used in the engine, everyone knows basically the advantages of engine technology, of course, some technologies will also have drawbacks. First of all, let's take a look at the double vortex tube, which has been used more commonly in recent years, such as BMW.
Because the engine has a set of regular ignition procedures, generally like the 4-cylinder engine is 1342, which will involve exhaust interference or exhaust efficiency, resulting in a late response to the turbine. The double vortex pipe is to divide the exhaust gas inlet into two channels, one cylinder and four cylinder exhaust, through one vortex pipe exhaust, and the second and third cylinders are exhausted through another vortex pipe, so the two do not interfere.
The double vortex supercharger gets rid of the problem of high-rotation intake air drop, then the heat dissipation speed will become faster, and the power output will be smoother. However, the ultimate power output stability of this supercharger is closely related to the housing material used.
For example, the recently hot ecotec 1.5T engine, because the power of the squeeze is relatively large, so it also uses a relatively stable and material optimization of the ordinary supercharger, in order to ensure the stability of the later turbine pressure when the pressure is higher. Since it involves machinery, it is inevitable that the coexistence of advantages and disadvantages will be inevitable, and there will be advantages and disadvantages, so consumers should not worry too much, because most of the advantages are greater than the disadvantages.
