Although the N20 is a four-cylinder engine, it is considered a replacement for the naturally aspirated ...
Compared with its N20 predecessor, the B48 uses a more undersquare design, and engine block in "closed-deck construction". [2] As with the N20, the block and head are made from aluminium. [3] Other features shared with the N20 include a twin-scroll turbocharger, direct injection, variable valve lift (Valvetronic) and variable valve timing ...

Engineering design was directed by BMW using their Valvetronic variable valve lift system on the intake side, flow-controlled oil pump, timing chain, single belt drive of all ancillary units, composite camshafts and cylinder head produced by lost-foam casting.
Chip tuning is changing or modifying an erasable programmable read only memory chip in an automobile's or other vehicles electronic control unit to achieve superior performance, whether it be more power, cleaner emissions, or better fuel efficiency. Engine manufacturers generally use a conservative electronic control unit map to allow for ...
