R 1200 CL

R 1200 CL
Engine
The engine is designed to run on premium
grade fuel (95 RON/92 AKI).The air fuel mixture
is ignited by a centrally placed spark
plug.
Directly connected to each spark plug are
the new direct connection ignition coils (ie:
F 650 CS). These coils eliminate the secondary
spark plug wire ensuring consistent
spark voltage over the lifetime of the motorcycle.
Due to the ignition coils, the cylinder
head covers are new.The ignition coils each
have a separate ground wire that connects
to the engine cylinder head.
The exhaust system with a hard chrome
plated surface is produced in three sections:
two exhaust manifolds consisting of a
55 mm double walled tube and a flangemounted,
1-section exhaust silencer with
short tail pipes.This has 4 chambers and is
based on the reflection and absorption principle.
In the exhaust silencer of the R 1200 CL, two
catalytic converters are used. The small
diameter and a flat design, offers a higher
sectional flow. The cylindrical catalytic converter
carriers have a diameter of 60 mm
and a length of 74 mm.
The heated O2 sensor is located in the
exhaust gas stream of the two exhaust manifolds
beyond the catalytic converters.
During the warm-up period from 60° C
motor oil temperature (just a few minutes
after starting), it already ensures that the
engine runs in accordance with the stoichiometric
mixture (lambda=1).
The catalytic converters are made of palladium
and rhodium. Palladium accelerates
the oxidation of hydrocarbons and carbon
monoxide. Rhodium reduces nitric oxide.
