There was an era when different automobile companies were in a race to increase their engine output by increasing the cubic capacity. Soon the market was flooded with cars that boasted 4, 5 or even six litre naturally aspirated engines. This trend became immensely popular and it gave birth to the muscle cars. Although these engines produced astonishing performance figures, but they were highly inefficient when it came to fuel economy.
Turbochargers are often associated with high performance cars, race cars and big diesel engines. More often called a turbo, this is a type of forced induction which uses the exhaust gases to add more air back into the combustion chamber. This leads to a significant increase in power output that does not add too much weight to the engine. Compared to a naturally aspirated engine of the same displacement, a turbocharged engine produces more horsepower. Continue reading
