Named for the German aerodynamicist W. Kamm, who discovered that drag begins to increase after the rear of a car's cross-sectional area is reduced to 50 percent of the car's maximum cross section.
A downshift in an automatic transmission caused by swiftly depressing the throttle. The Kickdown is designed to provide more power when accelerating under a heavy load through the use of a lower gear, but retain fuel efficiency when accelerating under a lighter load by staying in the higher gear.
Single wing nut for fastening a wheel to the hub. Easily removed and replaced, it is struck (knocked off) with a mallet on the wings.
Sensor mounted on the engine that is designed to detect the high-frequency vibrations caused by detonation. By employing a knock sensor, a computerized engine-control system allows an engine to operate very near its detonation limit: thereby improving power and efficiency.
International agreement among industrialized countries to reduce greenhouse gas emissions negotiated in Kyoto, Japan in December 1997. Canada committed to reduce its greenhouse gas emissions by 6 percent of 1990 levels between 2008 and 2012.
