Unit 5 - Cambridge English for Engineering
throttle
accelerator control on an engine
fly-be-wire
aircraft controls which operate moveable devices electronically, rather than mechanically
tighten
apply the correct torque
service
carry out planned maintenance
gearbox
case containing shafts with gears, usually with a gearshift mechanism, allowing gears to be moved to change between different gear ratios
replace
change an old or damaged part
examine
check carefully
tank
container for storing liquid
vibration
continuous high-frequency movement or shaking
properly
correctly
abrasion
damage to surfaces caused by friction
temperature gauge
device which shows a temperature reading
clearance
distance between components designed to fit together closely
starter motor
electric motor in an engine used to turn the engine in order to start it running
loose connection
electrical connection that is not fully tight, often causing the circuit to be broken, preventing current from flowing
drain
empty a liquid
reconnect
establish a connection again
systematically
every time
clutch
friction mechanism allowing engine motion to be transferred to wheels progressively
intermittenly
from time to time
radiator
heat-exchange device that dissipates heat into the air, usually from a hot liquid that is pumped through it
heat
high temperatures
hydraulics
high-pressure oil circuits used to push pistons called hydraulic rams
coolant
liquid in a cooling system
pressure
loads from expanding gases or liquids
filter
material with small holes located in a flow of gas or liquid; used to block solid particles
valve
mechanism for opening/closing/restricting the flow of gas or liquid along a pipe
piston
mechanism which transfers linear motion to rotary motion, usually pushed by expanding gas
suspension
moveable connection between a vehicle's chassis and its wheels, consisting of springs and dampers
spoilers
moveable panels on aircraft wings which increase drag and reduce lift; used to slow aircraft when descending and on landing
flaps
moveable panels on aircraft wings which increase lift to assist low-speed flight
engine
often refers to an internal combustion engine, which burns petrol or diesel
non-serviceable
part that cannot be repaired by maintenance technicians, only by the manufacturer
electrical contact
point where two electrical conductors are connected
fault/defect
problem
disconnect
remove or isolate from a circuit or network
top up
remove or isolate from a circuit or network
drag
resistance to movement through a gas or liquid
isolate
separate an electrical component or part of a circuit from the rest of the circuit to prevent electricity from flowing through it
major
serious
adjust
set up carefully by making small changes
minor
slight
fan
spinning device with blades used to generate a flow of air
shocks
sudden impacts
fuel injection
system for injecting fuel vapour into the piston cylinder of an engine
dismantle
take apart assembled components
turbine
transforms a flow of fluid into rotary movement
landing gear
wheels of an aircraft
misfire
when an engine is not running smoothly due to a fuel or ignition problem
faulty/defective
wrong
