BMW N42
Reciprocating internal combustion engine
- 1,796 cc (1.8 L)
- 1,995 cc (2.0 L)
The BMW N42 is a DOHC four-cylinder petrol engine which replaced the BMW M43 and was produced from 2001-2004.[1][2]
The N42 serves as the basis for the smaller N40 engine (which does not have Valvetronic).
The N42B18 won the 1.4-1.8 L category of the International Engine of the Year awards for 2001.[3]
In 2004, the N42 was replaced by the BMW N46 four-cylinder engine.
Design
Compared with its M43 predecessor, the N42 features a DOHC valvetrain, VANOS (variable valve timing) and an aluminium engine block.[4] It was the first BMW engine to have Valvetronic (variable valve lift).[5][6]
