Pic. 1.136. Types of three way catalytic converters
The three-way catalytic converter is an emission control device installed in the exhaust system (pic. 1.136).
Its purpose is to reduce the amount of pollutants in the exhaust gases.
Note. A large amount of unburned gases entering the three-way catalytic converter can cause it to overheat and create a fire hazard. To prevent this and other damage, follow the precautions below.
- - Use only unleaded gasoline.
- - Do not continue driving when the fuel level is extremely low; running out of fuel can lead to misfiring of the engine, placing excessive stress on the three-way catalytic converter.
- - Do not let the engine idle for more than 20 minutes.
- - Avoid giving the engine full throttle.
- - Do not start your vehicle by pushing or towing.
- - Do not turn off the ignition while the vehicle is moving.
- - Keep your engine in good working condition. Malfunctions in the engine's electrical system, electronic ignition/distributor system, or fuel system can result in extremely high three-way catalytic converter temperatures.
- - If the engine becomes difficult to start or stalls frequently, have your vehicle inspected as soon as possible. Remember, your Toyota dealer knows your vehicle and its 3-way catalytic converter system best.
- - To ensure proper operation of the three-way catalytic converter and the entire emission control system, it is necessary to carry out periodic inspections of your vehicle according to the Toyota maintenance plan.
