How does a turbocharger work? - ANS A turbocharger recovers waste energy from the
engine exhaust stream and uses it to power a turbine which in turn drives a compressor. This
compressor draws in ambient air, compresses it and then feeds it into the engine intake
resulting in a greater mass of air and, proportionally, a greater amount of fuel entering the
cylinders on the intake stroke. This increase in air and fuel results in the turbocharged engine
being more powerful and efficient than its naturally aspirated counterpart.
What does a camshaft do - ANS opens and closes cylinders' intake and exhaust valves. It also
runs the accessory gear drive which is connected at the end of the Cam shaft and runs the
magnetos, the engine driven fuel pumps, and the oil pump for the engine. These are all
connected to the accessory gear drive by small gears)
