NOTE:
When checking the combustion chamber
volume, engine must be cold, piston must be free
of carbon deposit and cylinder head must be lev-
eled.
1. Remove both spark plugs and bring one piston
to Top Dead Center a using a TDC gauge.
1. Bring piston to TDC
2. Obtain a graduated burette (capacity 0-50 cc)
and fill with an equal part (50/50) of gasoline
and injection oil.
1. Graduated burette (0-50 cc)
3. Open burette valve to fill its tip. Add liquid in
burette until level reaches 0 cc.
4. Inject the burette content through the spark
plug hole until liquid touches the top spark plug
hole.
1. Top of spark plug hole
NOTE:
The liquid level in cylinder must not drop
for a few seconds after filling. If so, there is a leak
between piston and cylinder. The recorded vol-
ume would be false.
5. Let burette stand upward for about 10 minutes,
until liquid level is stabilized.
6. Read the burette scale to obtain the quantity of
liquid injected in the combustion chamber.
Compare the obtained value with the table be-
low. The volume should be in the allowable
range.
NOTE:
When the combustion chamber is filled to
top of spark plug hole, it includes an amount of
2.39 cc corresponding to the spark plug tip. The
following table of combustion chamber volume in-
cludes this value.
7. Repeat the procedure for the other cylinder.
