A dirty diesel engine oil filter element can best be detected by ______.
A.visual inspection of the elements
B.the pressure drop across the filter
C.high lube oil sump temperature
D.decrease in oil viscosity from the filter
第1题:
increasing the quantity of starting air
increasing the lube oil pressure
heating the engine fuel supply
heating the engine jacket water
第2题:
visual inspection of the elements
the pressure drop across the filter
high lube oil sump temperature
decrease in oil viscosity from the filter
第3题:
the engine to run after the fuel has been secured
the engine to over-speed
a fire
all of the above
第4题:
Visual inspection of the element
the pressure drop cross the filter
high fuel oil tank temperature
increase flow rate from the filter
第5题:
clogged lube oil piping
excessive valve-guide clearance
high lube oil viscosity
low lube oil temperature
第6题:
an increased flash point
higher lube oil pressures
an increased viscosity
lower lube oil pressures
第7题:
changing filter elements would not interrupt engine operation
filtering occurs twice in each pass of oil through the system
clogging will not occur
dropping pressure is half of that through a single filter unit
第8题:
clogged filters
poor combustion
overloading of the diesel
shock of fuel lines
第9题:
Reduce engine speed to idle before removing the filter
Soak the dirty filter in kerosene only
Blow out the air inlet with compressed air
Cover the air inlet after removing the filter
第10题:
low oil pressure
high coolant pressure
leaking fuel injector
cracked cylinder head or liner
第11题:
loss of power
misfiring
low fuel oil pressure
All of the above
第12题:
high lube oil temperature
low lube oil temperature
excessive cylinder cooling
high air injection pressure
第13题:
decreased compression pressure
increased lube oil pressure
lower lube oil temperature
excessive leakage past the piston rings
第14题:
pitting
sludge
hard varnish
all of the above
第15题:
a dirty lube oil strainer
internal water leaks
an oil suction line restriction
excessive wears of the cooling water pump
第16题:
Dirty lube oil filter
Too much piston ring wear
High lube oil viscosity
Low lube oil temperature
第17题:
lube oil pump suction line
lube oil pump discharge line
bottom of the lube oil sump
outlet from the lube oil header
第18题:
Low lube oil temperature
Dirty lube oil strainer
Low lube oil pressure
High lube oil temperature

第20题:
Over speed
fire improperly
lose oil pressure
overheatrapidly
第21题:
determine the need for filter cleaning
measure any change in oil viscosity
prevent damage to the filter
determine the need for batch filtration
第22题:
increasing cooling water flow
increasing lube oil flow
dilution by fuel oil
adding SAE 70 oil
第23题:
Lube oil pressure gauge
Jacket water temperature gauge
Tachometer
Exhaust pyrometer
