A constant velocity (CV) joint is closely related to which of the following?
ball joint |
|
universal joint |
|
sprint joint |
|
master cylinder |
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.
The combustion chamber is enclosed by the:
piston ring |
|
piston |
|
cylinder head |
|
head gasket |
Cylinders act as a guide for the pistons that translate the heat energy of combustion into the mechanical energy necessary to move a vehicle. Piston rings seal the piston to the cylinder to contain combustion gases and also regulate the oil distribution between the piston and cylinder wall. A cylinder head closes in the top of the cylinder forming the combustion chamber which is sealed by a head gasket (head). The head provides space for air and fuel intake valves, exhaust valves, and mounts for spark plugs and fuel injectors.
The fluid reservoir stores the __________ that the master cylinder uses to maintain hydraulic pressure.
air |
|
brake fluid |
|
ethylene glycol |
|
brake oil |
The fluid reservoir stores the brake fluid that the master cylinder uses to maintain hydraulic pressure.
__________ results from oil buildup in the combustion chamber.
preignition |
|
engine knock |
|
detonation |
|
combustion |
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.
Which of the following maintains pressure in the cooling system?
water jacket |
|
water pump |
|
radiator cap |
|
thermostat |
The radiator is responsible for tranferring heat from the coolant to the outside air. Radiator hoses transfer coolant to and from the engine to the radiator and a radiator cap maintains pressure in the cooling system to increase the boiling point of the coolant mixture and thus allow it to absorb more heat.
