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.
