Turbocharged engines use a turbocharger to force extra air into the combustion chamber, providing more power and torque, especially at lower RPMs.
How Turbocharged engine works?
- In the Exhaust stroke, exhaust gases from the engine are directed into a turbocharger unit.
- These gases spin a turbine wheel, which is connected to a shaft.
- The shaft also spins a compressor wheel on the other side.
- The spinning compressor wheel draws in a large volume of ambient air, which is dense and hot.
- This compressed air is passed through an intercooler, which cools the air before it enters the intake manifold.
- Cooler, denser air allows more fuel to burn efficiently, generating more power output without increasing engine size.
Advantages of the Turbocharged Engine:
- Suitable for both petrol and diesel engines.
- Helps small engines produce power comparable to larger naturally aspirated engines.
- Delivers instant torque at low RPM, improving initial acceleration.
- Offers better fuel efficiency due to reduced engine size with similar output.
Disadvantages of the Turbocharged Engine:
- Higher Initial Cost – Turbocharged engines are more expensive to manufacture and purchase compared to naturally aspirated engines.
- Increased Maintenance Costs – More complex components like the turbocharger unit, intercooler, and related systems require regular maintenance.
- Turbo Lag – There can be a slight delay (known as turbo lag) between pressing the accelerator and the turbo providing boost, especially at lower engine
