2.3.3.2 air intake manifold lower body
2.4 fuel vapor control system In order that air could be exchanged for fuel tank, and to prevent fuel vapor from exhausting to atmosphere, fuel vapor is absorbed by active carbon and stored in it. Upon engine operating condition, stored fuel vapor will be timely and adequately sent to air intake hose and burned with mixture in combustion chamber. SQR480EC multi-port fuel injection system using and servicing 3.1 fuel and purge system using and servicing 3.1.1 Fuel grade used in Chery engine must be higher than 93#RON, and leaded gasoline or fuel grade lower than 93#RON CAN NOT be used. Leaded oil could do harm to the 3-way catalyst, resulting in the loss of oxidization and reduction function to harmful materials in exhaust. Lower grade gas will cause fuel injector being blocked, pin valve and regulator etc. being damaged, shortening components lifetime. Using leaded gasoline will cause a damaged 3-way catalyst converter, after which 3-way catalyst converter function will not recover even the right gas is used. If leaded fuel is added, the vehicle should be driven to specified repairing workshop and repaired as soon as possible. avoided. Burned under high temperature. The ideal temperature for a high purge ratio and long life time is s 400-800℃. A higher temperature will cause overheat catalyst, fast ageing, losing catalyst function; Catalyst hole blocked; (3) Under an over 800℃ temperature and last for 30 seconds, remaining gas in catalyst will cause 3-way catalyst converter being damaged. Therefore when engine operating, removing ignition coil wire for an operational engine is absolutely forbidden. 3.1.3 Poor engine operation may cause 3 way catalyst converter being damaged. Therefore, scheduled technique service must be done as per Servicing Manual. 3.1.4 Before engine stalls, let engine idle for some time and cool down gradually, lower heat impact strength which will do good to a prolonged engine components and 3 way catalyst converter life time. 3.1.5 After a long-time driving, the vehicle CAN NOT be immediately parked in a place where the 3-way catalyst may reaches flammable materials to avoid accidents caused by high temperature 3 way catalyst converter. 3.1.6 DO NOT depress throttle pedal when starting. ECU determines engine operating conditions upon throttle position. Once throttle pedal is depressed, throttle is opened and ECU cannot determine if engine is under operating condition and can not supply fuel correctoly.
