What if Forced Induction? | Types of Forced Induction Engine

Our vehicles drive the economy! Vehicles have played a key role in moving people from place A to place B or moving our goods to drive economic and consumption growth around the world! Well, technologies have evolved and so are our vehicles. From getting better engines to reducing carbon emissions from internal combustion engines and implementing small engines to produce more power, automotive engineering has come to the verge of new evolution.

In this blog with Autologygeeks, we are discussing how forced induction engines with turbochargers and superchargers changed the game of horsepower and torque. How diesel and petrol engines started giving more output with higher compression and became everyone’s favorite over naturally aspirated engines.

What is a Forced Induction Engine?

A forced induction engine utilizes a turbo or supercharger to increase its power output beyond what a naturally aspirated engine can achieve. These components achieve this by compressing air and forcing it into the engine’s combustion chamber, allowing more fuel to be burned and, as a result, generating more power. When fuel-injection systems or forced induction were not used, the car’s engine came with a carburetor to drive the air-fuel mixture in the combustion chamber. The difference between a turbocharger and a supercharger is mainly in how they are driven; a turbocharger uses the engine’s exhaust gas to spin a turbine that drives a compressor, while a supercharger is mechanically driven, often connected to the crankshaft via a pulley system. Both systems increase the amount of air in the engine, but they do so in different ways and with different efficiencies.



The turbocharging process can introduce a delay, known as turbo lag, between the moment the accelerator is applied and when the turbo produces the increased power. This happens because the turbo needs to spin up to an efficient speed using the exhaust gas flow, which doesn’t happen instantly. On the other hand, supercharging provides an immediate response to throttle inputs since it is mechanically connected to the engine, thereby eliminating the lag issue. However, superchargers can place a continuous strain on the engine, potentially reducing efficiency.

Regardless of the forced induction type used, turbos and superchargers aim to make more power by increasing the air density in the intake manifold and, consequently, in the combustion chamber. The introduction of a forced induction system may also involve other modifications such as upgrading the intercooler, which cools the compressed air before it enters the engine, and adjusting the compression ratio of the cylinders to handle the increased pressure and temperature of the forced air induction. Whether turbocharged or supercharged, these engines can significantly outperform their naturally aspirated counterparts both in terms of power output and efficiency, making them run at lower engine speeds and produce more power with similar displacement.



Are Turbochargers and Superchargers Different?

A turbocharger and supercharger a different types of forced induction-inducing mechanisms to let engines breathe better with intake air. Both methods help you to gain some increase in engine power and help make them fuel efficient by running them in their volumetric efficiency.

Yes, Turbochargers and Superchargers are indeed different components that serve the same purpose of increasing engine power and performance. The main difference between the two lies in their operation and how they are powered. Exhaust gases power turbochargers, while Superchargers are powered by a belt connected to the engine’s crankshaft. This difference in power source influences factors such as response time and overall efficiency.



Another key difference between the two is their placement in the vehicle. Turbochargers are typically mounted directly onto the exhaust manifold, whereas Superchargers are usually mounted on top of the engine. This distinction can affect the overall weight distribution and handling of the vehicle. Despite these differences, both Turbochargers and Superchargers serve the purpose of increasing engine power through forced induction. Drivers can choose between the two based on their preferences and driving needs.

Turbocharged engines need intercooling to supply cold air to the engines. The majority of the muscle cars use supercharging as they have big engines to spool the superchargers. Smaller engines however work with turbochargers to get air into the engine with force.

Conclusion – Turbocharger and Supercharger in Your Vehicles!

Supercharging and turbocharging an engine would help you gain better performance. If you compare a supercharged engine or a turbocharged engine compared to a similar displacement NA engine, you will see increased performance and the engine will make more torque at a lower rpm.

So, if you want performance and want to force more air into the engine to make engines work better in hilly areas, forced induction is the best way to increase the performance of your car and motorcycle.
