Technologies in modern engines

BMW engines are using technologies such as:

• Direct injection (called High Precision Injection by BMW). Engines including the N53 (mostly sold in European markets) and the turbocharged N54 and naturally-aspirated N53 (mostly European markets only) used the more costly piezo injectors. However, where "lean burn" cannot be used (such as in North America), less costly solenoid-type injectors are often used- for example in the N54's successor, the N55.^[2][3]
• Turbocharging. BMW uses the name "TwinPower Turbo" to describe both twin-turbo engines and engines using a single twin-scroll turbocharger. The "TwinPower Turbo" moniker initially denoted engines that utilize a twin-scroll turbocharger which was unveiled in 2009^[4] (the calendar year, not the model year) with the N55 and N74 being the first engines to use this technology.^[5] Nonetheless, BMW has started to apply the TwinPower label retroactively to earlier turbocharged engines that are still in production like the N54 and N63 which have twin turbochargers but do not use twin-scroll technology.^[6][7][8] The S63 V8 and N74 V12 engines have two twin-scroll turbochargers.
• Variable valve lift (called Valvetronic by BMW)
• Variable valve timing (called VANOS by BMW)
