EFI system
• Air-to-fuel ratio control system
This controls the air-to-fuel ratio of the
mixture in such a way that the three-way
catalyst may perform the purification of
emissions with the best possible effi­
ciency.
• Control system for deceleration period
This reduces CO and HC emissions by
cutting the fuel supply during decelera­
tion period. Also, this prevents overheat­
ing of the three-way catalyst.
Three way catalyst
The three-way catalyst functions for con­
verting CO, HC and NOx into harmless
carbon dioxide (CO ), water (H,0) and ni­
