Control arms connect a vehicle's suspension to the frame. The connection to the wheels is through:
pins |
|
ball joints |
|
knuckles |
|
bushings |
Control arms (upper and lower) connect a vehicle's suspension to the frame. The connection to the wheels is through ball joints which allow the control arms to turn and move up and down simultaneously. The frame connection uses bushings.
Cylinder air and fuel intake valves, exhaust valves, and mounts for spark plugs and fuel injectors are contained in the:
head gasket |
|
cylinder head |
|
manifold |
|
piston ring |
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 firing order of the cylinders in an engine can be found by:
observing the direction in which the intake valves open |
|
observing the order in which the intake valves open |
|
identifying the cylinder number |
|
reversing the cylinder number |
The firing order of the cylinders in an engine is different than the cynlinder numbers and can be found by observing the order in which the intake valves open.
Which of the following is not a function of the oil pan?
acts as the engine oil reservoir |
|
cools engine oil |
|
feeds the oil pump |
|
screens debris from oil |
The oil pan contains the engine oil reservoir of from four to six quarts of oil and feeds the oil pump through the oil pickup tube. An oil strainer floats at the top of the oil in the oil pan and screens debris from the oil before feeding it to the oil pump.
What is the function of the head gasket?
to seal the engine block from the cylinders |
|
to seal the brake assembly from external contaminants |
|
to connect the transmission to the drive train |
|
to seal the exhaust system from the drive train |
A head gasket is a gasket that sits between the engine block and cylinder heads to seal the cylinders to ensure maximum compression and avoid leakage of coolant or engine oil into the cylinders.
