Q

What is brake fade? How does it occur?

A

Loss of braking due to excessive use of brakes. Excessive braking causes them to heat and expand, creating wear.

21
Q

Torque

A

Creates a rotational motion, helps increase speed

22
Q

How long should you let an engine cool before turning it off?

A

3-5 minutes

23
Q

Lugging

A

When throttle is applied when manual transmission is in too high a gear for rpm on engine

24
Q

Overthrottling

A

Injecting Diesel engine with too much fuel- can’t be burnt fast enough.

25
Q

Nfpa 1901

A

Standard for auto fire app

26
Q

Sirens

A

Off on limited access highways

27
Q

At what speed do apps outrun audible device range?

A

50mph

28
Q

Strobe light activated preemption devices

A

Strobe lights on app used to activate sensors in traffic lights

29
Q

Traffic signal preemption devices

A

Traffic control systems activated by siren

30
Q

GPS based traffic signal preemption devices

A

Uses gps to transmit data to a radio receiver on traffic light

31
Q

Nfpa 1500

A

Safety

32
Q

Skidding

A

Excessive or abrupt braking

33
Q

Visual lead time

A

Scan ahead

34
Q

Braking distance

A

Distance travelled from time of pushing brakes to actual stop of vehicle

35
Q

Total stopping distance

A

Combo of drivers reaction distance and vehicle braking distance

36
Q

Reaction distance

A

Distance travelled from when driver moves foot from gas to brake

37
Q

Acceleration skid

A

Gas pedal applied too quickly- lose traction- ease off acc, straighten front wheels

38
Q

Locked wheel skid

A

Braking too hard at a high rate of speed, locking the wheels. Doesn’t matter which way the wheel is turned. Slow and straighten front wheels

39
Q

ABS

A

Minimize skidding. Computer that monitors each wheel and controls pressure to brakes. Sensing device sends speed of tires to computer. When wheel begins to lock- computer compares to other to see if it should be turning. It reduces brake pressure and allows wheel to turn and then brakes again.

40
Q

Aux braking systems

A

Reduces brake fade, and service brake maintenance costs. 4 types- ehxhaist brake, engine compression brake, transmission output retarder, electromagnetic retarder

41
Q

Exhaust brakes

A

Least capable. Uses valve to restrict flow of exhaust, creating back pressure for braking

42
Q

Engine compression brakes

A

Converts mech energy into heat by compressing engine intake and creating exhaust.

43
Q

Electromagnetic retarders

A

On driveline or rear axle.electromagnetic field made by supplying electrical power to coils in retarder. Inhibits rotation of rotor and creates braking torque.

44
Q

Transmission retarders

A

Viscous property of auto transmission fluid to retard driveline. Trans fluid put into retarder and energy is is absorbed into fluid. Affects rear wheels and adds heat to trans fluid.

45
Q

Auto traction control (atc)

A

Reduces engine torque and applies it to wheels that still have traction.

46
Q

Driver controlled differential lock

A

Forces both wheels to turn at same speed resulting in a lock of the differential to maximize traction

47
Q

Inter axle differential lock

A

Allows speed diffs in the rear driving axles. Creates one solid driveline to get full torque from engine.

48
Q

Roll Stability control

A

Reads accelerator and senses rollover. Computer slows app by reducing engine torque. May apply service brakes to wheels

49
Q

Electronic stability control

A

Applies brakes independently to aim app in direction of steering (steering wheel sensor)

50
Q

Stability system safety

A

Helps with stability around corners and changes in direction

51
Q

Tillering

A

Tight turns and maneuvers. Tiller axle- allows tillers of tractor trailer app to maneuver through tight traffic.

52
Q

Intake/discharge caps

A

Never remove a cap for a pressurized pump. Open bleeder or drain valve.
