Also known as multiviscosity oils. |
MultimeterAn electrical measuring tool with functions for volts, amps and ohms. |
MultiplateA clutch mechanism having a series of friction and steel plates in a clutch drum assembly. One set of plates is splined to the drum and the other to a centre shaft so that drive through the clutch is via the drum, friction faces and the centre shaft. |
MultiplexedIn signal transmission where each set of signal pulses is given a certain time or frequency slot. This allows a great number of individual signals to be carried by a common conductor. |
MultiplexerA unit used for signal transmission where each set of signal pulses is given a certain time or frequency slot. This allows a great number of individual signals to be carried by a common conductor. |
MultiplexingA common conductor system for digital signal transmission where each set of signal pulses carries its own unique identity. This allows a great number of individual signals to be carried by the common conductor. |
MultiplugA connector with more than one electrical terminal inside. |
Multipoint Fuel InjectionGasoline electronic fuel injection system with injectors in each inlet manifold spraying fuel in towards the inlet valves in the ports of each cylinder. Also known as port injection. |
