INTRODUCTION
The N62TU is an advanced development of the N62.
> N62TU
The 8-cylinder spark-ignition engine N62TU has been modified. Compared to
the N62, the engine
develops more output and torque.
The N54 and N52KP meet ULEV II requirements for 2007. There are not many
changes to the emission
systems on these engines. The N54 engine has 2 underbody catalysts in addition
to the "near engine" catalysts
already in use from the N52.
The N51 engine, however, is a SULEV II compliant engine which
