Engine effective power, also known as net power, is the amount of power that is actually available at the output of the engine after accounting for various power losses due to friction and other factors. It's a measure of the usable power that's available to move the car forward.

As an automotive engineer, there are several ways you can increase your car's engine effective power. Here are some common methods:

  1. Improve air intake and exhaust flow: One of the easiest ways to increase engine power is to improve the air intake and exhaust flow. This can be done by installing a high-flow air filter and a performance exhaust system. This will allow the engine to breathe more easily, resulting in better power output.

  2. Increase engine compression: Increasing the engine's compression ratio can also increase its effective power. This can be done by using high-compression pistons or milling the cylinder head to increase the compression ratio. However, this method should be approached with caution as it can lead to engine damage if not done correctly.

  3. Install forced induction: Forced induction, such as turbocharging or supercharging, can significantly increase engine power by forcing more air into the engine. This method is often used in high-performance engines and can provide a significant increase in power output.


  1. Optimize fuel delivery: Optimizing the fuel delivery system can also improve engine power output. This can be done by upgrading the fuel injectors, fuel pump, and fuel pressure regulator to provide more fuel to the engine.

  2. Upgrade engine components: Upgrading components such as the camshaft, valves, and valve springs can also increase engine power. These components can improve the engine's ability to breathe and rev higher, resulting in better power output

It's important to note that these methods should be carefully considered and implemented by a qualified automotive engineer. Any modifications made to the engine should be done with caution, as they can affect the engine's reliability and lifespan. Additionally, it's important to ensure that any modifications made comply with local regulations and emissions standards.
