A constant velocity (CV) joint is closely related to which of the following?
master cylinder |
|
universal joint |
|
sprint joint |
|
ball joint |
Like CV joints, universal joints (U-joints) are located at each end of a drive shaft and allow the shaft to operate at a variable angle with the item it is driving. Universal joints perform the same basic function as CV joints but CV joints have a wider range of operation.
What function does a two-stroke cycle engine perform on the second stroke?
combustion and exhaust |
|
compression and combustion |
|
fuel intake and exhaust |
|
fuel intake and compression |
The two strokes of a two-stroke cycle engine are fuel intake and compression then combustion and exhaust.
Which of the following is not a part of the oil pump?
oil filter |
|
oil galleries |
|
all of these are part of the oil pump |
|
pressure relief valve |
The oil pump is driven by the camshaft and is responsible for pumping oil through the oil galleries (passages) that run throughout the engine. It also contains the oil filter and a pressure relief valve which prevents excessive pressure from building up in the lubrication system.
Which of the following is a relay that connects the battery to the starter motor when the ignition key is turned?
solenoid |
|
actuator |
|
ignition coil |
|
alternator |
The cylindrical solenoid is a relay that safely connects the high amperage battery to the starter motor when the ignition key is turned. This current then allows the engine to turn at a high enough speed to start.
Which engine stroke starts with the piston at top dead center?
compression stroke |
|
exhaust stroke |
|
intake stroke |
|
power stroke |
The four-stroke piston cycle of internal combustion engines starts with the piston at top of the cylinder head (top dead center or TDC) during the intake stroke. The piston moves downward in the cylinder creating a vacuum that pulls an air-fuel mix into the combustion chamber through the now open intake valve.
