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 -

Chapter 3 Fuel SystemSection 1 Check Fuel System PressureOn-board inspection
1. Check the operation of the fuel pump.
(1) Connect the positive and the negative of the battery to
appropriate connector sockets of the fuel pump (see Figure 3-1).
Attention: Do not start the engine.
If there is pressure present, you will hear that the fuel is flowing.
If there is no pressure present, check the fusible cutout, fuse, EFI
open-circuit relay, fuel pump, ECM (Electronic Control Module) and
circuit joint.
(2) Turn the ignition switch to "OFF".
2. Check the pressure of the fuel.
(1) Check whether the battery voltage is more than 12V.
(2) Disconnect the negative wiring cable from the battery.
(3) Mount a pressure gauge on the fuel input pipe
(see Figure 3-2).
(4) Connect the negative terminal of the battery.
(5) Measure the fuel pressure.
Fuel oil pressure: 265-304kPa
If the pressure is low, check the fuel pipe and connection,
fuel pump, and fuel filter. If the pressure is too high,
replace the regulator.
(6) Start the engine. Measure the fuel pressure at idle speed. The
fuel pressure is 265-304KPa. If the pressure is unsatisfactory, checkFigure 3-1
Figure 3-3 Figure 3-2Fuel SystemCheck Fuel System Pressure3-15the fuel pump, pressure regulator, and injector, and replace if necessary.
(7) After shutting down the engine, check the fuel pressure and
keep the specified pressure for about 5 minutes. The fuel pressure is:
147KPa.
3. The fuel oil pressure regulator (DR) (see Figure 3-3).
Mounting position: On the distributing pipe for fuel.
Faults: Too low or too high fuel pressure, or hard to start.
General causes: Using poor fuel for a long time results in: 1.
strainer blocked; 2. serious leakage caused by particles and impurities.
Other reasons: Man-made mechanical damage, etc.
Maintenance precautions: During maintenance: 1. Never impact the diaphragm element with high pressure
gas; 2. Never clean it with aggressively corrosive liquid; 3. No distortion caused by external force.
Easy measuring method: For the system with oil return, connect a pressure gauge for the fuel on the suction
pipe, start the engine, and run at idle speed. Now, the fuel pressure in the engine should be about 260KPa; pull out
the vacuum pipe of the fuel pressure regulator, and the pressure should be 300KPa approximately.Battery

Section 2 Fuel Pump Inspection1. Fuel pump (1) Check whether the resistance of the fuel pump is 0.2~3.0 ohm¸ at 20°C. If not, replace the fuel pump (see Figure3-4).
(2) Fuel oil pump running:
Switch on the fuel pump with a battery and check. If the operation is unsatisfactory, replace the fuel pump or
wires (see Figure 3-5).
The test should be done within 10s to protect the coil from burning out.
2. Fuel injector assembly
Oil injecting quantity: 40~50cm3/s.
Tolerance of each injector: not more than 10 cm3.
If the fuel injecting quantity is not up to the specification, replace the injector.
Check leakage: Under above conditions, disconnect the wire from the battery, the fuel should not drip one per
minute.Figure 3-4 Figure 3-5BatteryOhm
