Car modification itself is a reflection of its own personality. Therefore, it is necessary to modify it according to your own preferences and personality.
Give you a suggestion for novice modification, you can refer to it!
How can an ordinary car be modified into a streetcar that attracts everyone's attention? Let's introduce it to you slowly. Please correct me if I don't speak well.
1, Modification of the air intake system As we all know, the engine system drives the piston in the form of explosion by burning mixed oil and gas, so whether the air intake is smooth or not will seriously affect the combustion effect. If the combustion effect is not good, the power output will inevitably decrease or even the fuel consumption will increase. Therefore, the modification of the air intake system is a very critical part for a car. The primary modification of the air intake system is to change the paper air filter of the original car into a high-flow style for modification. A good high-flow style will make the air intake smooth and have excellent filtering effect. For supercharged cars, because the air is compressed into the air pipe, the air flow is relatively large. At this time, it is necessary to consider using the mushroom head. The mushroom head can suck in a lot of air more effectively because of the spherical design. There are several points to pay attention to: 1, and the air intake pipe should not be bent as much as possible. Too large a camber or too thick an inner wall will lead to a greater resistance of air in the pipeline, which will directly affect the efficiency of air intake. 2. Finally, the engine compartment and the mushroom head will be separated with heat insulation materials, because there will be relatively few oxygen molecules in the air at high temperature, which will affect the combustion efficiency. If possible, it is best to directly send fresh air from the air duct outside the car (of course, this is more useful in the modification of racing cars, and the engine of street cars generally will not work to that extent. The visual effect is greater than the actual effect.) When the air intake is completely modified, it is necessary to replace the enlarged throttle according to the situation. For example, the water pipe is very large, but the faucet is very small, and the water flow will not be much.
2. The modified exhaust system has smooth air intake, and the exhaust must keep up with the speed, or it will be trapped in the engine. At present, the exhaust pipes on the market can be roughly divided into two types: straight exhaust and back pressure drum. The two tail sections have their own advantages and disadvantages, and the modification can be selected according to their actual needs: the design of straight exhaust removes the back pressure cavity, so that the exhaust gas can be discharged from the engine more smoothly. The advantages of this design are smooth exhaust, and the higher the engine speed, the better it runs. Everyone should know that racing cars are in straight line, because to maintain high speed, there are still many racing cars that start at 4-5 thousand rpm. That's the reason. The characteristics of back pressure drum are just the opposite to that of straight exhaust, and the speed increase is powerful at low rotation, but it will be less enjoyable at high rotation because the exhaust is not smooth enough. Civil vehicles are all back pressure drums, so starting at 2500 rpm may be the most suitable. Like the air intake system, if it is really modified to a fever level, we must pay attention to the exhaust performance of the whole exhaust pipe, otherwise the irregularity in one place will be enough to offset most of the effects, and the corresponding modified parts include the head coke, the head section, the middle section and the tail section just mentioned.
3. The modification of the ignition system is simple. The better the ignition effect, the better the combustion. In this respect, the modified parts include iridium spark plug, high-intensity ignition wire, ground wire (to better let the current have a loop) and electric ballast.
4. The power of brake modification is strong, and the brakes of the original car are naturally not enough. You can switch to a complete set of brake suits for brake modification, and you can also modify the brake discs, brake pads and brake steel throats according to your own needs. If you switch to a brake suit, you should choose a ring with a suitable size according to the size of the brake disc. Generally speaking, 15 inch ring can hold a brake disc with a maximum size of 280MM,1.
5, tire upgrade Choose a flat tire that suits you according to the size of the ring. In this respect, the tire must not be greedy and cheap, and it can be used as much as possible. Because the tire is the only medium for the car to contact with the ground, the performance of the car will not be able to play if the tire is not well grasped. When upgrading the tire, it is generally changed to a large ring thin tire. If the diameter of the ring becomes larger, the thickness of the tire will be reduced accordingly, and the total diameter should be maintained similar to that of the original car. It is not good to be too big or too small.
6. The modified vehicle of the control system has great power, and the speed is fast, and the brakes are no problem. However, when cornering, it feels that the vehicle will turn over, which also affects the speed. Generally, there are several ways to modify the control system, such as changing the short spring for the shock absorber for the street, and installing the whole vehicle reinforcement for the shock absorber, which has another advantage, reducing the body, which is very effective in terms of perception and actual use. The reduced body can effectively reduce the wind resistance coefficient and stick to the ground.
7, appearance modification A successful modified streetcar must have a pair of personalized appearance. At this time, you can choose a set of large surrounding kits and body flowers that suit you, dress up your car well, or you can choose a modified light group on the market. Do your best to build a car.
summary
When you do this, a qualified streetcar will come out. Of course, if you drive it, you will gradually be dissatisfied with your current motivation and accelerate your performance. Congratulations, you have taken another step and started to March into the fever-level players. Further modification can add a booster system to the car, modify the fuel supply system and fuel supply computer, change the transmission system, lighten the car, deal with the cooling system, and so on. I won't say much about these, because I believe you have understood the principle by the time you get to this point. I know that many people will not have the patience to see it here, but I still wrote it, because some people may need to know this knowledge. Hehe, I hope that I was not fluent in writing when I didn't read the book well.
