How does natural inhalation improve motivation?

Performance tires with high flattening rate are more sensitive and less deformed during vehicle steering, thus increasing grip. Compared with the cast aluminum alloy rim with light weight, high hardness and good heat dissipation, the forged alloy rim has lighter weight, higher strength and higher cost.

2. Improve the throttle valve

There are two ways to improve the throttle: ① improve the electronic throttle by replacing the servo motor with faster action. (2) The single throttle is changed to multi-throttle, aiming at sports cars and racing cars. The improvement method is to install a throttle valve on each intake pipe. This structure also

It is called multi-throat direct injection type. Compared with the single-throat type, the multi-throat type has greatly improved the inflation efficiency, but the improvement cost is also higher.

3. Replace the fuel injector

After the engine has been greatly improved, if the fuel injection time required at high speed is longer than one intake stroke of the engine, the continuous fuel injection of the injector will not provide enough fuel, so it is necessary to replace the injector with a larger fuel injection quantity.

4. Spark plugs

It is an introduction to change the ordinary nickel-copper spark plug with low cost, short service life of 20,000 kilometers, poor high temperature resistance and low ignition energy into an iridium metal spark plug with a service life of 6.5438+10,000 kilometers, high temperature resistance above 2,000℃ and strong ignition ability, but the corresponding cost is also relatively high.

5. Fuel control valve

The original oil return valve is generally 2.5 ~ 4 kPa, and the pressure values of different models are different, so it cannot be adjusted. Increasing fuel pressurization can increase oil return pressure, slow down oil leakage, increase injection pressure, and improve injection atomization while increasing injection quantity.
