How Do You Explain A Turbo Engine?
Turbos are used on many late-model vehicles to enhance the performance of small displacement engines—usually four-cylinder engines. The small displacement engines have advantages in low fuel consumption, although they fall deficient, in most cases, in the power department. A turbo engine has higher horsepower, but does not sacrifice fuel economy, especially if the vehicle is driven normally (without putting your foot in it everywhere you go). Explain how a normally aspirated engine operates where the intake of fuel is concerned. A normally aspirated engine relies on engine-produced vacuum for the induction of air, which is always subject to atmospheric pressure. As atmospheric pressure continuously changes, the air induction in terms of cubic feet per minute (CFM) changes as does the horsepower for a given pressure. Hot, moist air is thin with a resulting reduction in horsepower; whereas a cold, dry air has a corresponding increase in horsepower. The cubic-inch displacement of an eng
