BMW M44 Straight-4 Engine
From 1996 to 2001
The BMW M44 is a straight-4 DOHC 1.9 piston engine which replaced the M42 and was produced from 1996-2001. It was produced alongside the M43 straight-4 engine, with the M44 being the higher performance engine. The M44 was replaced by the N42 engine.
Compared with the M42, the M44 has an extra 6% displacement, hydraulic lifters, hot-wire MAFand other detail changes. As per the final versions of the M42, the M44 has a dual length intake manifold (called "DISA" by BMW). Peak power is the same as the M42, however torque is increased by 5 N·m (4 lb·ft).

The M44B19 has a displacement of 1895 cc, which is achieved through a bore of 85 mm (3.3 in) and stroke of 83.5 mm (3.3 in). A compression ratio of 10:1 is used, along with Bosch Motronic 5.2 fuel injection.
The crankshaft has an increased stroke from the M42's 81mm and is cast instead of forged. Also revised were the valve actuators which are of a roller pivoting arm type. This design replaces the M42's cam on spring cup design and results in a 30% decrease in rotational resistance from the cams.
