Emission control system
Oxygen sensor
High-pressure common rail
system
The oxygen sensor is used to detect the
concentration of oxygen in the exhuast
gases and feeds it back to ECU in the
engine. The engine will automatically
adjust the air-fuel ratio in the engine to
achieve the best combustion eciency of
the fuel and reduce the content of carbon
monoxide, hydrocarbons, and nitrogen
oxides in the exhaust gases.
The high-pressure common rail system
consists of a high-pressure oil pump, a
fuel rail, fuel injectors and a controller.
Warning
● Do not modify any part of the engine
or emission control system.
● The emission control system may
vary with dierent engine models.
For the particular equipment, please
