Engine management
system Bosch Motronic MED 9.5.10
Fuel Super unleaded with RON 95
(super plus RON 98 leads to an
increase in torque in the medium
engine speed range)
Exhaust gas aftertreatment Primary catalytic converter,
main catalytic converter, lambda
control
Exhaust emission standard EU4
The 1.6l 85 kW FSI engine
This engine originates from the Golf 2004.
It differs from this only due to its switch to lambda 1
operation and super unleaded RON 95.
Special characteristics
Stratified charge and homogeneous lean operation
have been omitted due to the switch to lambda 1
(homogeneous operation). This leads to the
occurrence of less nitrogen oxide, and the omission of
complex trapping and regeneration of this.
This leads to the following changes:
- The exhaust gas temperature sender has been
omitted,
- instead of the NO
x
storage reduction catalytic
converter, a
three-way catalytic converter has been installed,
and
- instead of the NO
x
sender, a transient
lambda probe has been installed.
The switch from super plus RON 98 to super unleaded
RON 95 is achieved via ignition angle adjustment.
Operation with RON 91 is not permitted,
as ignition is retarded to the control limits in this case.
Information on the fuel system can be found in self-
study programme No. 334
"The FSI engine fuel system".
