N62 engine
Introduction
- General information
The N62 engine is a completely new development from the
NG (New Generation) series, and is available in two engine-
capacity versions, B36=3.6 l and B44=4.4 l.
The development objectives were:
- A significant reduction in fuel consumption
- A reduction in the emission of pollutants
- Increased power
- Improved torque and torque curve
- Improved engine acoustics
In order to achieve these objectives, a complete package of
measures was introduced in the following areas:
- Engine mechanics
- Valve timing
- Intake air guidance
- Subsequent treatment of exhaust emissions
- Engine management control
The most important features of the new N62 engine are:
- 8 cylinders in 90º configuration
- 2 four-valve cylinder heads
- Light-alloy design
- Newly-developed variable intake manifold
- Valvetronic system
In conjunction with the newly-developed intake manifold, the
Valvetronic system, to which the intake valve lift can be adapted,
ensures optimum engine capacity.
Throttle valve use is conditional for engine load control.
The N62 is the best engine in its class. At this time there is no
other engine on the market which uses comparable technology.
