Engine strengthening of modified cars, what are the modifications of automobile engines

Increasing horsepower is not necessarily related to increasing rpm. However, increasing the rotational speed is also a way to realize the potential.

Again. Horsepower is not necessarily related to the speed, for example, an engine can idle up to 8000 rpm, but with the load, it may be difficult to reach even 6000, why? Because the power is not big enough.

The original engine is limited to the lubrication conditions, the cooling conditions and the strength of each component, and the speed is naturally not too high. However, by strengthening the internal parts, such as the forged piston connecting rod crankshaft, the strength problem was solved. It's also easy to enhance heat dissipation, not to mention.

The lubrication system is upgraded at the same time, and the big problems are basically solved. It's a bit of an exaggeration to increase it a few times, but it's not impossible. The reason why I can withstand it is nothing more than the strengthening I mentioned above.

In addition, the body of some engines itself has great potential, and there is no problem to improve some performance even if it does not make any upgrades, such as WRX or the domestic Volkswagen 1 8T engine, which has relatively large potential.

The 2 5-liter engine of the domestic ninth-generation WRX also belongs to the American version and is different from the Japanese version, but this engine is not old It is based on the naturally aspirated 2 5-liter engine upgrade and improvement Whether it is the strength of the engine body and the potential for modification, it is not optimistic, but there is no problem with normal use and minor changes Moreover, this 2 5-liter engine pays more attention to the torque at low speed and the requirements of emissions.

The engine can be replaced, the frame can also be changed, and the body color can also be changed, provided that you must apply to the DMV for a change, and you can only agree to it, for example, it is very common for an accident car to change the shell, and as for changing to other types of engines, there should be no problem, at least I know that the DMV, these idiots, have not yet been able to figure out the difference between these engines.

Then replace them with reinforced parts, middle cylinders and crankshafts, pistons, etc., etc., all of them are replaced with reinforced forged parts specially produced by advanced tuning factories and the body is also strengthened

The best way to transform the engine to improve the power: 1. Circuit: By increasing the ignition wire, spark plug, and current balance device of the automobile power protector, we can reduce the power load, increase the ignition energy, improve the flame propagation speed, and shorten the flame propagation distance.

2. Oil circuit: Gasoline enters the engine cylinder after atomization through the fuel injector, but the degree of gasoline atomization determines the mixing effect with air. Therefore, the better the gasoline atomization, the more conducive it is to mix with air and fully combustion.

3. Air passage: Increasing the amount of air entering the engine cylinder per unit time and reducing the engine intake resistance is the goal of the engine intake part. The usual practice is to replace the original high-flow type, and then install an explosion-proof seal, place it in the air intake box, and decompose the incoming air clusters to produce a large amount of negative ion air through its own energy release, which is arranged into a chaotic and disordered linear motion of the original air molecules.

1.Modification methods for vehicle power enhancement include installing a high-flow air filter instead of a filter screen to increase air intake.

2.Replace the cylinder gasket or modify the cylinder.

3.The MAX Ignition Booster is installed to change the air composition and help the ingredients burn.

4.Because the engine will produce resistance during operation, the amount of air inhaled into the combustion chamber of the engine cannot reach the standard value, so the ordinary air filter element is modified into a large flow air filter element to reduce the intake resistance and improve the power.

5.If you want the engine to produce more power in combustion, you can increase the compression ratio.

6.The most common way to increase the compression ratio is to replace the thinner cylinder head gasket to reduce the volume of the combustion chamber and increase the compression ratio.

7.The ignition coil is equipped with a maximum ignition boost voltage, and the fire finger rock plug is excited by the current to make it fully combust with gasoline, thereby reducing the formation of carbon deposits and greatly reducing fuel consumption.

8.Because the throttle is sensitive, the speed is fast, and the power will be increased by 15%-20%.

Automobile engine modification has the following: 1. Power: Generally, the upgrade power starts from the exhaust pipe, and the order is the tail section, the middle tail section, and the whole section.

Generally, if the whole section is changed, it will be upgraded together with the computer program. And, of course, there's the upgrade of the three-way catalysis of the movement. Then there is the air intake system, which can be replaced with a "mushroom head" with a larger air intake.

If there are higher requirements, the turbine can be replaced, the cylinder expanding, etc.;

2. Control: from the simplest installation of reinforcements, to upgrading stabilizer bars, wheels, tires, to replacing shock absorbers, brakes, etc.;

3. Appearance: Of course, all kinds of latte art are the most common, as well as the color change of the whole car, the addition of the tail wing (strictly speaking, the tail wing should be counted in the control, but the current domestic market plus the tail wing is basically for good looks), front and rear surround (the same as the tail wing);

4. Audio-visual: The easiest thing is to upgrade the navigation, and then upgrade the audio, add power amplifier, add subwoofer, do modeling, lighting, etc. You can even add batteries and upgrade the generator system;

5. Comfort: Upgrading the suspension can also be counted into this category, but at present, the purpose of upgrading the suspension is to obtain better cornering performance, that is, to adjust the suspension to be relatively hard, and the cornering performance will be very good, but the comfort will be reduced;

Millions of subsidies for car escorts.

Intake and exhaust.

Forgings. Broken turn. The crankshaft is balanced at 10,000 revolutions. Reduction of compression ratio plus turbo to play high supercharging. Change the camshaft.

That's basically it. What a spark plug. Cylinder line these. It's all a lie. What an electronic throttle accelerator. These are all crooked. Ignition computer. Ignition Booster these. It's all a lie.

At present, most of the domestic modification methods are modified turbocharging.

Due to the fact that there are strict regulations on modified cars in the country. So many of the ways to increase the horsepower of the engine are unrealistic. Then there is the enlargement of the cylinder bore. Increase the area of the main power drive gear De ··· Flywheels, lightweighting, and so on.

Hello, normal modification is nothing more than to increase the power of the engine Unfortunately, the overall design of the engine has been fixed to the data of the valve mechanism and fuel supply system design at the initial design It is nothing more than a floating value of up and down percentages This floating value is generally about ten percent For example, with a motorcycle with a displacement of 125, it can be extended to the limit of 250 Unfortunately, such an expansion Although it can make the output of the engine reach the maximum value, it will also shorten the service life of the engine to one-sixth of the original life So Excessive modification must be considered clearly Generally in foreign modifications are more because the cost of foreign cars is low, there is no difference between mandatory scrapping, so many foreign modification families add what strong oxygen modification system to the car, so that the vehicle can only be scrapped after participating in a few more competitions, and China's current modification can not flourish Some small modification shops are nothing more than to replace some external components of the engine, such as high-voltage lines or spark plugs, and replace them with pressure-resistant and high-temperature resistant ones, such as adding a ringing throat, adding a turbo strong pressure intake or increasing the exhaust branch pipe These small modifications It doesn't make any sense at all, if it is a major modification, it needs to be moved, steel drums, pistons, piston rings, crankshafts, crankshaft connecting rods, crankshaft pads, water tanks, upper and lower water pipes, fan belts, etc. According to the survey of our group, it is recommended that you do not easily change the original car design, because the original car design values and service life and kilometers are matched, once changed, it is easy to cause unnecessary mechanical failures, and even spontaneous combustion, etc., I hope our answers can help you!

If your engine torque is not very high, it can be modified.

What I'm talking about is not very large, it should be below 300nm.

However, this modification should be illegal. Moreover, when modifying, be sure to find a qualified modification factory and one or more qualified professional engineers.
