Air/Fuel Mixture
Air/Fuel Mixture Also it is called the air/fuel ratio, the air/fuel mixture is ratio of air to fuel present in an engine during combustion. The correct air/fuel mixture will result in good engine power and efficiency. The wrong mixture will result in suboptimal performance and efficiency. On older engines, this mixture is made in the carburetor. On newer engines, the fuel injection system injects the correct amount of fuel directly into the cylinder for the best combustion .
