engine Flashcards
what checks would you have to carry out after fitting a camshaft ?
timing
what checks would you be doing if you were using a DTI on a crankshaft ?
end flow
state a typical good reading for a dry compression test ?
120-150 PSI
what does DTI stand for ?
dial test indicator
what would be the correct tightening sequence for a cylinder head ?
middle outwards
what would be the effect of valve timing if the valve clearance was excessive ?
the valves would open later and close sooner
on a 4 stroke engine how many revolutions would the camshaft do to 1 full revolution of the crank shaft ?
0.5
where in the engine would shell bearings be used ?
big end bearing on the connecting rod
if number 1 cylinder is on the power stroke , what would number 3 be on
compression because 1 and 4 are the same just like how 2 and 3
what would be the effect of valve timing if the valve clearance was less than usual ?
valves would open sooner and close later
what test would be carried out if the inlet valve was leaking air and hissing ?
cylinder leakage test
what defines how much of the air fuel ratio goes into the cylinder ?
compression ratio
what does TDC stand for ?
top dead centre
what does BDC stand for ?
bottom dead centre
what would happen if the wet cylinder liner does not seal properly on the bottom gasket ?
the coolant will leak into the sump
