Check compression (engine 2.0 l

The minimum engine speed 300 min -1. Compare the testimony of the values of compression. The difference between the values of maximum pressure between the cylinders should not exceed 100 kPa (1 bar).

Installation components

Replace spark plug with a special tool KM-194-E in the cylinder head and tighten the moment 25 Nm Connect the ignition module for spark plugs. Tighten the two screws fastening point 8 Nm Install the ignition module cover on the lid of the cylinder head. Connect the wiring harness ignition module.

NOTE Before the verification procedure warming up the engine to operating temperature (oil temperature - 80 ° C).

Removing the intake manifold

Remove the intake manifold. Loosen the mounting bolt and remove the vent hose from the engine cylinder head cover.

Fig. 2.62. Mounting inlet pipe: 1, 3,

4 - clamps, 2 - screw fixing

Remove the clamps and separate the inlet pipe from the turbo and remove it (Figure 2.62). Remove the air hose pressurization. To do this, remove the two clamps and disconnect the air hose supercharger. Loosen the 4 bolts and separate the vacuum line from the bracket and remove the tube deflection air pressurization.

Removing the ignition module

Disconnect the wiring harness connector from the ignition module. Remove the ignition module in the direction of the arrow shown therein.

Fig. 2.63. Components shooting in

dismantling the ignition module: 1 ignition module cover, 2 - wiring harness connector ignition module, 3 - a special tool, 4 - ignition module

Loosen the mounting bolts and detach the ignition module from the spark plugs, using a special tool KM 6009 (Fig. 2.63). Remove the spark plug using a special tool KM-194-E. Open the throttle, using the device TECH 2. Use verification program compression (TECH 2). Use a compression tester with a rubber cone and a measurement range up to 1750 kPa (17.5 bar).

Verification procedure

Fig. 2.64. Connecting tester

Connect the tester and turn the starter at the 4 s (Fig. 2.64).

NOTE Use a compression tester with a rubber cone and a measurement range up to 1750 kPa (17.5 bar).

Minimum engine speed - 300 min -1. Compare the testimony of the values of compression. 167
