Benelli TNT125 Service Manual

Introduction to EFI
This motorcycle adopts the
small engine EFI
(electronic fuel injection) system of Delphi
Corporation. This system achieves closed-loop control,
ECU fuel injection and ignition control through oxygen
sensor. Three-way catalytic converter is used to handle
the gas after the combustion of engine, to convert it into
harmless gas and discharge it to the atmosphere. This
system uses closed-loop control self-learning system,
which can effectively eliminate the manufacturing
differences of system and related mechanical parts,
improve the overall consistency of the motorcycle, and
eliminate the error of motorcycle caused due to wear
and other causes after actual use.
