Pic. 2.21. Camry intake and exhaust system: 1 - three-component catalytic converter; 2 - exhaust manifold; 3 - intake manifold; 4 - main muffler; 5 - three-way catalytic converter; 6 - air filter
Two resonators, side compartment and PET material* (polyethylene terephthalate) used in the development of the inlet pipe and air filter hose. Application of ETCS-i (intelligent electric throttle control system) provided improved accelerator control. Intake manifold (see fig. 2.21) made of plastic for weight reduction and heat transfer from the cylinder head. A two-stage exhaust control system reduces noise and vibrations in the main muffler.
* The use of a porous material made it possible to divert the air pulsation at the inlet to the outside, relative to the inlet pipe.
