Cooling & Lubrication systems, Ignition Circuits Flashcards
Viscosity is?
The tendency of a liquid or gas to resist flow
An impulse coupling is inhibited at higher than normal rotational starting speeds by?
Centrifugal force
If the ground wire between the magnetos and the ignition switch of a piston engine becomes disconnected the most noticeable result will be that?
The engine cannot be shut down by turning the ignition switch to the “OFF” position.
The drum sump oil system for a piston engine incorportates an oil tank with normally two stack pipes installed. Stack pipes can be found where?
Both in the bottom of the tank
The purpose of a distributor in an ignition system of a piston engine is to distribute?
Secondary current to the sparking plugs.
the rapid magnetic field changes in the primary coil of the magneto of a piston engine are produced when the?
Contact breaker points open
Cooling air for a reciprocating engine is obtained by means of?
Ram air.
An impulse coupling is installed on a magneto of a piston engine to?
Provide a stronger spark on top dead centre for engine starting
The ignition system of a running piston engine receives electrical energy from?
Rotating permanent magnets.
The main reason for opening the cowl flaps is to control the?
