Which of the following statements about v-type cyllinder arrangement is false?
common in motorcycles, cars, and trucks |
|
has an odd number of cylinders |
|
engine is shorter than an inline engine |
|
has two rows of cylinders |
A v-arrangement has two rows of cylinders in a V-shaped block with a crankshaft at the bottom of the V. Any even number of cylinders is possible in this configuration from the V-2 that's commonly used in motorcycles up to V-12 or bigger for large trucks. The V design produces a shorter engine than an in-line cylinder configuration and allows for better air-fuel distribution.
Which of the following is not a component in the engine lubrication system?
pickup tube |
|
oil filter |
|
pressure relief valve |
|
differential |
In engine lubrication, oil remains in the oil pan until the engine is turned on. It then gets sucked up the pickup tube by the oil pump and pressurized. This pressure is moderated by the pressure relief valve and the oil is fed through the oil filter into the engine to lubricate it.
The primary purpose of the muffler is to:
quiet exhaust |
|
remove harmful gases from the exhaust |
|
cool the exhaust |
|
reclaim unburned fuel |
The muffler follows the catalytic converter and absorbs sound to help quiet load exhaust. It is followed by the exhaust pipe which is the final exit point for exhaust gas from the vehicle.
__________ are made with wide gap coils of rigid steel cable and both hold the vehicle chassis up off the ground and absorb energy from wheel movement making for a smoother ride.
suspension springs |
|
shock absorbers |
|
ignition coils |
|
control arms |
Suspension springs are made with wide gap coils of rigid steel cable and both hold the vehicle chassis up off the ground and absorb energy from wheel movement making for a smoother ride.
__________ results from oil buildup in the combustion chamber.
engine knock |
|
combustion |
|
detonation |
|
preignition |
Preignition results from the buildup of fuel deposits and/or oil in the combustion chamber. These deposits increase chamber pressure and reduce heat tranfer to the coolant. The trapped heat then raises the temperature of the air-fuel mix to the point that it combusts before ignition.
