1.2L REVOTRON ENGINE 104 MAINTENANCE OF CLOSED COUPLED CATALYTIC CONVERTER Closed Coupled Catalytic Converter should be flushed by giving full throttle (4 to 5 times) in standing condition of vehicle on daily basis. In addition to this it is recommended to run the vehicle at high speeds (80 to 100 kmph) for few km as this will help to flush the carbon soot deposits from exhaust system and closed coupled catalytic converter. High speed running of the vehicle may be done periodically to avoid chocking of Closed Coupled Catalytic Converter. Alternative method for flushing operation for cleaning the catalytic converter is by directing dry compressed air draft (3 to 4 bar) in the direction of catalytic converter inlet, after removing it from the vehicle. AVOID  Push start or tow-starting the vehicle. (Use jump leads).  Long (not more than 10 seconds) repeat (not more than 3 times) starting of the vehicle. Investigate the cause for difficulty in starting and rectify the same.  Long idling (to warm-up) if the engine is running rough, after a cold start.  Switching “OFF” the ignition when driving down the hill.  Fuel almost empty.  Pre- Coating/Painting of Catalytic Converter. WARNING  Avoid parking of vehicle over inflammable materials, such as dry leaves; grass etc. as exhaust system is hot enough to initiate fire. CAUTION  Ensure exhaust system and catalytic converter is not blocked and is free from obstruction.  Blockages in the exhaust can create back pressure, low top speed, poor pick up, black smoke, carbon build up and low mileage.  Excessive carbon build-up / sticky valve.  Damaged vacuum lines.  The Catalytic converter should not be dropped from a height. If dropped, it should not be used. CAUTION  The Catalytic converter should not be dropped from a height. If dropped, it should not be used. EXHAUST ASSY. REAR (MAIN SILENCER) REMOVAL 1.
