ASE CERTIFICATION PRACTICE PAPER 2026
COMPLETE SOLUTIONS
◉ abrasive cleaning. Answer: cleaning that relies on physical
abrasion, such as wire brushing and glass bead blasting
◉ ABS. Answer: abbreviation for anti-lock brake system. ABS
electronically monitors wheel speed and prevents wheel lock-up by
rapidly cycling the brakes during panic stops and when stopping on
low-friction surfaces
◉ ABS control valves. Answer: control valves that are actuated by
the ABS electronic control unit (ECU) to ensure wheels are optimally
braked.
◉ acidity. Answer: in lubrication, the presence of acid type
chemicals, which are identified by the acid number. Acidity within oil
causes corrosion, sludges and varnish to increase
◉ actuator. Answer: A control device that delivers mechanical action
in response to a vacuum or electrical signal.
◉ additive. Answer: a material added to the engine oil to give it
certain properties
, ◉ aeration. Answer: the process of mixing air with liquid
◉ air bag (SRS). Answer: actuated component of the supplemental
restraint system developed for safety.
◉ air duct. Answer: a tube, channel or other tubular structure used
to carry air to a specific location
◉ air gap. Answer: space or gap between spark plug electrodes,
motor and generator armatures and field shoes
◉ air-fuel ratio. Answer: the proportion of air to fuel by weight in
the fuel mixture drawn into the engine.
◉ air lock. Answer: a bubble of air trapped in a fluid circuit that
interferes with the normal circulation of the fluid.
◉ alignment. Answer: an adjustment to bring into a line
◉ alloy. Answer: a mixture of different metals (e.g., solder, and alloy
consisting of lead and tin
