Hyundai Ioniq (AE): Engine Electrical System / Exhaust Emission Control System

DescriptionA ratchet tightening device on the threaded fuel filler cap reduces the chances of incorrect installation, which seals the fuel filler. After the gasket on the fuel filler cap and the filler neck flange contact each other, the ratchet produces a loud clicking noise indicating the seal has been set.

DescriptionExhaust emissions (CO, HC, NOx) are controlled by a combination of engine modifications and the addition of special control components.Modifications to the combustion chamber, intake manifold, camshaft and ignition system form the basic control system.
