Modification Scheme of Cruze Power 1.5l

Chevrolet Cruze power modification scheme: 1. Spark plug: Iridium spark plug with service life of 65,438+100,000 km, high temperature resistance and strong ignition ability replaces ordinary nickel-copper spark plug with service life of 20000km, poor high temperature resistance and low ignition energy, but the corresponding cost is relatively high. Pay attention to the selection of thermal resistance. Too low will cause the engine to fail to accelerate, and too high will cause carbon deposition. Naturally aspirated cars can be strengthened in Japan at 5 ~ 7 degrees, and turbocharged cars above 7 degrees are better.

2. Due to the inaccurate data transmission of various instruments 3360, the pointer instruments of the original vehicle often cannot meet the requirements of fine monitoring of vehicle working conditions under the condition of a large number of modifications, and need to be replaced.

3. The valve lift and opening angle of the large-angle camshaft 3360 are larger, which ensures that more combustible mixture enters the cylinder and the exhaust is smoother.

4. main reduction ratio and gear: increasing the main reduction ratio and encrypting the transmission ratio of 1 ~ 4 can improve the acceleration of the whole vehicle, but at the expense of reducing the maximum speed. Therefore, the speed loss can be compensated by increasing the tail gear, encrypting the transmission ratio of 2 ~ 4 gears and thinning 5 gears.

5. The high-voltage line 3360 replaces the high-resistance line with the low-resistance line, and the original car is generally about 5 K. This can transfer the energy released by the ignition coil to the spark plug to the maximum extent, but it should be used as symptoms such as heart fire and interference.

6. Balance bar: connect the shock absorber tower of the vehicle to enhance the rigidity of the vehicle body and prevent the shock absorber and even the vehicle body from being deformed due to violent manipulation.

7. Step up the throttle: In order to greatly increase the intake air flow without restriction, the engine will knock because the air-fuel ratio is too low.

8. The light piston 3360 with high compression ratio lightens the load on the crankshaft and connecting rod of the engine, making the engine react quickly and have stronger explosive force.
