Arrangement of elements of the emission control
To prevent contamination of not completely burned and vaporized gas, save the dynamic characteristics of the car at high fuel efficiency using multiple systems reduce emissions. They include the following: - On-board diagnostics system; - A fuel injection system; - A system of post-combustion exhaust gas (EGR); - The fuel vapor recovery system (EVAP); - A system of positive crankcase ventilation (PCV); - The catalytic converter. If there is a suspicion that the system of emission control malfunctions, pre-check system of fuel supply and the ignition system. Diagnosis of some systems of emission control requires special tools and equipment.

Arrangement of elements of the emission control on models with engines DOHC: 1 - the electromagnetic valve of clearing of the canister with the activated carbon; 2 - PCV valve; 3 - way catalytic converter (UCC); 4 - the canister with the activated coal; 5 - two-way valve; 6 - the catalytic converter (MCC)

It must be remembered that the most common cause of failure of the systems of emission control is a break or disconnecting the hose or vacuum, so first check the integrity and reliability of their connection. Arrangement of elements of the emission control on the car shown in
