There is no such thing as a perfect invention, we can always make something better, cheaper, more efficient or environmentally friendly. It is possible to build an engine that will go faster, further or use less fuel. One way to improve an engine is to use a turbocharger, a pair of fans that harness waste exhaust power from the back of an engine to cram more air into the front, delivering more oomph than you would normally get.
Have you ever watched cars buzzing past you with sooty fumes streaming from their tailpipe? It is obvious exhaust fumes cause air pollution, but it’s much less apparent that they’re wasting energy at the same time. The exhaust is a mixture of hot gases pumping out at speed and all the energy it contains—the heat and the motion (kinetic energy)—is disappearing uselessly into the atmosphere. Wouldn’t it be neat if the engine could harness that waste power somehow to make the car go faster? That’s exactly what a turbocharger does. Car engines make power by burning fuel in sturdy metal cans called cylinders. Air enters each cylinder, mixes with fuel, and burns to make a small explosion that drives a piston out, turning the shafts and gears that spin the car’s wheels. When the piston pushes back in, it pumps the waste air and fuel mixture out of the cylinder as exhaust. The amount of power a car can produce is directly related to how fast it burns fuel.
The more cylinders you have and the bigger they are, the more fuel the car can burn each second and (theoretically at least) the faster it can go. If you know how a jet engine works, you’re halfway to understanding a car’s turbocharger. A jet engine sucks in cold air at the front, squeezes it into a chamber where it burns with fuel, and then blasts hot air out of the back. As the hot air leaves, it roars past a turbine (a bit like a very compact metal windmill) that drives the compressor (air pump) at the front of the engine. This is the bit that pushes the air into the engine to make the fuel burn properly.
