Design, development and variant notes
The M44 enlarged the M42's displacement to 1.9 litres and introduced roller valve actuation, a hot-wire air-flow meter and a cast crankshaft. It retained an iron block, aluminium head and DISA variable-length intake.
Wikipedia lists Bosch Motronic 5.2 and a 10.0:1 compression ratio for M44B19, and notes that the plastic cooling outlet can leak as it ages.
Variant dimensions and compression
These values are associated with the named variant and source qualifier; equipment and market specifications can differ. A dash means the value is not listed here.
| Variant | Bore (mm) | Stroke (mm) | Compression ratio | Source qualifier |
