Because the intercooler is actually a turbocharging kit, its role is to improve the efficiency of the engine's air exchange. For supercharged engines, the intercooler is an important component of the supercharging system. Whether it is a supercharged engine or a turbocharged engine, an intercooler needs to be installed between the supercharger and the engine intake manifold.
The role of the intercooler:
The role of the intercooler is to reduce the intake air temperature of the engine. So why lower the intake air temperature? (1) The temperature of the exhaust gas discharged from the engine is very high, and the temperature of the intake air will be increased by heat conduction through the supercharger.
Moreover, the density of the air will increase during the compression process, which will inevitably lead to an increase in air temperature, which will affect the charging efficiency of the engine. If you want to further improve the inflation efficiency, you need to reduce the intake air temperature. Data show that for every 10 drop in the temperature of the charge air at the same air-fuel ratio, the engine power can be increased by 3 5.
2) If the uncooled charge air enters the combustion chamber, in addition to affecting the charging efficiency of the engine, it is easy to cause the combustion temperature of the engine to be too high, causing detonation and other failures, and will increase the content of NOx in the engine exhaust gas, resulting in air pollution.
In order to address the adverse effects of the air heating up after pressurization, an intercooler was required to reduce the inlet air temperature.
How it works: An additional 5%-10% more power can be obtained with a well-designed intercooler. There are also some cars that use overhead intercoolers, through the holes in the engine cover to obtain cooling air, so before the car starts, the intercooler will only be blown by some hot air blowing from the engine compartment, although the heat dissipation efficiency has been affected, but because the intake air temperature will increase in this case, so the fuel consumption of the engine will drop a lot, which also indirectly reduces the work efficiency of the engine, but for the powerful supercharged car, Unsteady starts, caused by too much power, can be alleviated in this situation, and Subaru Subaru's Impreza series is typical of overhead intercoolers.
In addition, the biggest advantage of the overhead intercooler layout is that it can effectively shorten the travel of the compressed gas to the engine.

Suning Nagubao sealant electrical appliances.
Guangzhou Naigubao automatic inflatable sealant solves the frustration caused by tire breakdown, and can delay tire aging, extend the application life, and reduce the puncture rate. People unknowingly save a lot of precious time, making the driver's driving smoother and easier.
The technical design principle of Guangzhou Naigubao automatic inflatable sealant is: the liquid containing natural polymer compounds and synthetic polymers is pre-injected into the tire according to a certain amount, if the tire has holes, it will be congested; When the tire has a hole, the overflow air discharges the polymer liquid as a whole, and the polymer squeezed into the hole reflects with the air, and it is firmly blocked when the tire is no longer leaking, and the sufficient pressure in the tire is maintained, so that the vehicle can continue to drive, and the possible accidents are avoided.
Inject once and automatically patch over and over again! Active tire repair inflator also has a good fire extinguishing effect, the consequences are not much the same as the usual fire extinguisher, is your best companion on the road, keep a bottle at home and in the car, both urgent and unprepared.
When the vehicle is driving after the tire is punctured again, regardless of whether the puncture is set out or not, the natural polymer compounds and synthetic polymer compounds in the product are under the action of centrifugal force when the air pressure and the tire rolls, and the puncture is polymerized in four places or holes to form a polymer with a certain plasticity, elasticity and strength, so as to tightly infarct the flaw, and can withstand the impact of the overloaded tire and the ground for a long time. The gas trickle in the tires does not leak, and the car continues to drive as usual, without the driver noticing!

Models with GKUI19 system can be loaded into the car.
In response to the needs of old car owners for smart cars, ECARX, a subsidiary of Geely Automobile, has launched its own brand of after-installed smart car machine, which is claimed to be a customized upgrade solution for original vehicles, which realizes the wiring harness of the original car and realizes richer functions with the help of the GKUI 19 system.
At present, ECARX has two versions of the GKUI 19 rear loader, which is suitable for Boyue and the version for Emgrand GS GL.
These two car machines are very interesting in terms of pricing, the original positioning of the Boyue model is higher than that of Emgrand GS GL, and theoretically the after-loading machine should also be more expensive. However, the actual situation is the opposite, at present, the Boyue GKUI 19 rear installation machine is very cheap, and the Emgrand GS GL's GKUI 19 rear loading machine ** will be much higher.
Precautions for loading pure good machine:
It should be noted that there is not much difference between the two in terms of configuration and function, and it may even be just a difference in the definition of the bundle, but the gap is indeed a bit unclear, and I don't know what kind of consideration ECARX made based on what kind of consideration Fubi made.

1. What is machine vision?
Machine vision is the use of machines instead of human eyes to make measurements and judgments. The machine vision system refers to the machine vision product (i.e., the image acquisition device, divided into CMOS and CCD) to convert the ingested target into an image signal, transmit it to a dedicated image processing system, obtain the morphological information of the photographed target, and convert it into a digital signal according to the pixel distribution, brightness, color and other information; The image system performs various calculations on these signals to extract the characteristics of the target, and then controls the action of the equipment in the field according to the results of the discrimination. >>>More
