Among them, improving engine power is one of the most common measures. As the "heart" of the car engine, the improvement of its performance directly affects the acceleration, power and fuel consumption of the whole vehicle. Today, let's discuss how to upgrade the engine so that your vehicle can leapfrog to the peak of the engine. Step 1: Understand the significance and method of engine upgrade. The main significance of engine upgrade is to improve the horsepower, torque and response speed of the car, and enhance the acceleration, uphill and overtaking performance of the vehicle. Generally speaking, the methods of engine upgrade can be divided into the following types: 1.Replacing the high-performance intake system and exhaust system By replacing the high-performance intake system and exhaust system, the engine can get more oxygen and accelerate the combustion process. At the same time, the improvement of the exhaust system can also reduce the exhaust resistance, improve the engine exhaust efficiency, and make the reciprocation movement smoother. Two. Installing a turbocharger or a mechanical supercharger can increase the engine intake and improve the engine performance. Because turbochargers and mechanical superchargers can compress air, so that more air can enter the engine and burn more fully. 3. Replace the high-performance ignition system. The high-performance ignition system usually has greater ignition energy, higher ignition frequency and faster reaction time, so that the fuel burns more completely and releases more energy. Step 2: Choose the appropriateBefore choosing an engine upgrade plan for your own model, you need to first understand your own model, engine type and the maximum power and torque recommended by the manufacturer. Based on this information, combined with your driving needs and budget, you can choose the most suitable upgrade plan for you. For example, models like Volkswagen Golf can generally increase horsepower and torque by more than 20%, while shortening the acceleration time of 0-100km/h. Most Japanese cars, which are common in the second-hand car modification market, choose to modify the turbocharger, because the turbine can make full use of the engine exhaust, improve the air intake, and give full play to the engine performance. In addition, it is also necessary to consider the impact of the upgrade on fuel consumption and vehicle service life. If you pay more attention to speed and acceleration, you can choose a higher-performance upgrade scheme.If you pay more attention to fuel consumption and maintenance costs, you can choose some more moderate upgrade plans. Step 3: Choose a reliable upgrade store. In the process of upgrading, you need to choose a reliable loading store. This requires you to do a good job of full investigation and inquiry, check the qualifications and experience of the store, confirm the quality of the store's finished products, and the after-sales guarantee policy, etc. In addition, it is also necessary to pay attention to the safety issues during the upgrade process. For example, when installing a turbocharger or a mechanical supercharger, it is necessary to consider whether the leakage of the vehicle can really withstand the increased pressure, otherwise it will directly cause a serious car accident due to damage to the pipeline or mechanical parts? In summary, engine upgrade is one of the most direct ways to improve car performance, but it is also necessary to choose a suitable upgrade plan, a reliable loading shop, and pay attention to safety and security issues.Therefore, we need to pay attention to the actual operation to make our car more perfect and jump to the peak of the engine.
