Engine is the heart of any automotive. Whether it is a passenger car, a two-wheeler, or a commercial vehicle, all automotives need engines to run. It’s the engine that generates power and transforms the fuel energy to kinetic energy of the wheels. Therefore, it is very important to monitor and maintain the performance levels of the engine.

Here are best ways to improve engine performance:

Engine Displacement

Engine displacement is defined as the total volume of air and fuel mixture that the car engine draws during one complete cycle moved by the piston from the top dead center to the bottom dead center. Dead center is the position of the piston when it is farthest or nearest to the crankshaft.

To improve engine performance, it is very important to increase engine displacement. This is because if the engine draws higher volume of air and fuel mixture, it will definitely generate more power. This can simply be done by increasing the size of the cylinder or by adding more number of cylinders to the engine. These cylinders play a significant role in the car engine as both compression and combustion takes place in these cylinders. Therefore, if the size is more, more mixture can be fused it, which in turn will generate higher power output. This improves engine efficiency.

Engine Compression Ratio

Compression ratio is the degree to which air and fuel mixture in the internal combustion engine is compressed before ignition. Increasing this ratio is one of the best ways to increase power and torque, thereby improving engine performance.

Higher compression ratio enables the car engine to extract more energy from the given volume of air and fuel mixture. It also causes better mixing of the power. This in turn, produces enhanced power during ignition and extracts more useful energy from the withdrawn power.


An intercooler is a device used in car engine to cool the air between successive heating stages. Air outside is comparatively hot and therefore it is very important to cool the air before fueling it into the engine. Later compressed air raises the temperature due to high pressure generated by the movement of the piston in the engine.

Hot air expands less during combustion and reduces the amount of energy generated. The air should always be cool before it enters the engine cylinder and that’s why intercoolers are usually placed in the most of the turbocharged and supercharged cars.
