BMW N46

Automotive Engines

The BMW N46 was a naturally aspirated inline-four petrol piston engine produced from 2004 to 2015, replacing the N42. It served as the basis for the smaller N45, which lacked Valvetronic. Compared with the N42 it has a revised crankshaft, intake manifold and valvetrain, and a 2007 update called the N46N changed the intake manifold, the exhaust camshaft and the engine control unit from Bosch Motronic ME9.2 to MV17.4.6, with a redline of 6,500 rpm. The direct-injected N43 was introduced in 2007 as its successor but was not sold where fuel is high in sulfur, so the N46 stayed in production beside it until the turbocharged N13 replaced the last N46 models in 2015. Versions of 1.8 and 2.0 litres powered the E46 and E90 3 Series, the E87 1 Series and the E83 X3.
