Rover M-Series engine
From Wikipedia, the free encyclopedia
The Rover M-Series (or M16) is a 4-cylinder, DOHC internal combustion engine introduced by the Austin Rover Group in 1986 for the then-new Rover 800-series.
The M-Series was produced only in one cubic capacity - 1994 cc (2.0 L), and was a 16 valve development of the older British Leyland O-Series unit first seen in 1978. For the Rover 800, there were two different versions, with single point fuel injection (for the Rover 820e) or multi-point injection (for the 820i). The M-Series uses the same cylinder block as the O-Series unit as found in the Maestro and Montego, which mates with the Honda PG-1 manual gearbox.
In 1990, the M-series was also installed in the Rover 200-series, before being superseded in 1992 by the similar T-Series which was a development of the same design.
