Frequently Asked Questions

What does "digital" mean?

Digital is the way computers process information, using combinations of binary digits, either zero or one. Digital coding can represent any given value as a coded number (for example, the ideal amount of air in relationship to the amount of fuel at a certain throttle setting). And, because the range of values that can be represented is infinite, digital codes allow exceptionally high precision. By using a small computer to "manage" an engine with digital codes for all of the various aspects of engine operation, such as fuel-to-air ratio, load and air temperature, engineers are able to design engines that run better, deliver better fuel economy and reduce emissions.

The opposite of digital is analog. Carburetors are analog instruments. Their actuation is mechanical and must be preset to adjust for specific operating conditions. Electronic fuel injection, used on Suzuki outboards, is digital and provides virtually infinite settings to ensure ideal combustion in any conditions.

A personal computer is digital. An abacus is analog.
