12. Check the compressing pressure (see Figure 1-4).
(1) Warm up and switch off the engine.
(2) Remove the secondary wire.
(3) Remove the spark plug.
(4) Check the compressing pressure in the cylinder.
a.Insert the pressure gauge into the spark plug bore.
b. Throttle widely opens.
c. Rotate the engine crankshaft and measure the compressing
pressure (see Table 2).Figure 1-4Table 2Cylinder compressing pressure (KPa)Pressure difference range of cylinders of this model (KPa)Minimum compressing pressure (KPa)MR479Q MR479QA MR481QA

980
Attention:
The electric quantity in the battery should be always enough, and the engine speed should be not less than
250r/min.

Check the compressing pressure in other cylinders in the same way.
Measure as soon as possible.
(5) If the compressing pressure in more than one cylinder is relatively low, fill a bit engine oil to the cylinder
through the spark plug bore, and repeat step a to c to check.
Tip:

If the compressing pressure is increased after the oil is filled, the piston ring or the cylinder may be worn or
damaged.
If the pressure is still low, the valve may be jammed or badly sealed, or the washer may be leaked.
13. Check CO/HC.
(1) Start the engine.
(2) Keep the engine running at a speed of 2500 r/min for about 180s.
(3) During idling, insert the test bar of CO/HC instrument into the exhaust pipe about 40cm depth at least.
(4) Check the concentration of emission of CO/HC at idle speed and at a speed of 2500 r/min respectively.
Tip:

Measure within 3 minutes.
Test the concentration of emission and lambda value of CO/HC at idle speed and at a speed of 2500 r/min
respectively according to GB18352.3-2005 standard.
(5) If the concentration of CO/HC is not up to standard, carry out fault diagnosis by following the steps below.
(1) Check oxygen sensor.
(2) Refer to Table 3 to find possible causes, check and repair.Engine AssemblyEngine Inspection3-4 -
