How does it feel when you have a car with turbocharged engine, which gives you more power than the a naturally aspirated engine. Today, turbocharging of engines are preferred due to the better performance figures as well as fuel efficiency. There are various turbocharged cars available in India and here is an explanation of how a turbocharger works and the different types of turbochargers.
How it works?
Turbocharged engines deliver more power when compared to the same engine without one. The exhaust gases of the engine are redirected to a turbine. This forces more air into the engine for added combustion which results in more power due to the added impact of explosion in the Internal Combustion Engine. This boosts the overall power and torque of an engine after a certain rpm. A mild throttle input while driving also aids in better fuel efficiency over the same engine’s mileage figure without a turbocharger. In addition, a turbocharger also reduces the engine noise as it wraps the sound of the intake.
Different types of turbocharged engines available are variable geometry turbochargers in which the angle of the fins in the turbocharger change as per the driver’s throttle input. Parallel twin turbochargers have two turbochargers that work in tandem with each other. Each turbocharger is driven by half of the engine’s exhaust and the intake from both turbos is forced into a common intake later on sending it to the engine after passing through the manifold. A parallel twin turbo has less ‘turbo lag’ than the single turbocharger set up. Sequential turbochargers refer to the turbochargers in which the motor uses one turbo at a lower engine speed and the other at a higher engine speed. This system helps in decreasing the turbo lag without compromising with the power and boost output.
The affordable turbocharged petrol engine cars in India are the Fiat Linea T-jet 1.4 litre, Ford EcoBoost 1.0 litre, VW Polo GT TSI, VW Vento TSI 1.2 Litre, Skoda Octavia 1.8 TSI, the upcoming Maruti Suzuki Baleno RS and some more
