3The Min. compression pressure: 980 kPa
The tolerance range of the cylinders pressure: 100 kPa
Notice:
zEnsure sufficient battery power and the engine speed is no less than 250 RPM (revolutions per minute).zCheck the compression pressure of other cylinders in the same way.
zComplete the measure as quick as possible.
(4) If the compression pressure in several cylinder is too low, fill some engine oil to the cylinder via the
hole of the spark plug. Check by repeating step 1-3.
Hint:
zIf the compression pressure is improved after filling oil, the piston ring or the cylinder may be abrased
or damaged.
zIf the pressure is still too low, the valve is stagnation or poor seal, or there is a leakage in gasket.
10. Check CO/HC
(a) Start engine.
(b) Running engine at 2500rpm for approximately 3 minutes.
(c) Insert CO/HC meter testing probe into tailpipe at least 40cm during idling.
(d) Check CO/HC concentration at idle and 2500rpm.
Hint:
zComplete measurement within 3 minutes.
zTest the CO/HC emission concentration at idle and 2500 rpm on QC/T630-1999 standard.
(e) Take the following steps to diagnose the fault if the CO/HC concentration does not comply with standard .
(1) Check the oxygen sensor operation.
(2) See (Table 3) for the possible cause and check and repair.
