rpm range
1critical RPM range — A range of engine RPM that must be avoided, or the engine operation within this RPM range restricted, because the engine is likely to be damaged by continued operation. This is because the natural vibrational frequency of the engine propeller… …
2Dynamic range — For other uses, see Dynamic range (disambiguation). Dynamic range, abbreviated DR or DNR,[1] is the ratio between the largest and smallest possible values of a changeable quantity, such as in sound and light. It is measured as a ratio, or as a… …

5Turbocharger — A turbocharger, or turbo, is an air compressor used for forced induction of an internal combustion engine. Like a supercharger, the purpose of a turbocharger is to increase the mass of air entering the engine to create more power. However, a… …
6Expansion chamber — An Expansion chamber is an exhaust system used on a two stroke cycle engine to enhance its power output by improving its volumetric efficiency. It makes use of the energy left in the burnt exhaust exiting the cylinder to aid the filling of the… …
7Close-ratio transmission — A close ratio transmission is a transmission in which there is little difference between the gear ratios of the gears. Consequently, note that the word close implies near , not shut. The gear ratio numbers are in a smaller numeric range, hence… …
