Diesel engines are typically well suited to turbocharging due to two factors: A "lean" air–fuel ratio, caused when the turbocharger supplies excess air into the engine, is not a problem for diesel engines, because the torque control is dependent on the mass of fuel that is injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture.

The Swiss industry played a pioneering role with turbocharging engines as witnessed by Sulzer, Saurer and Brown, Boveri & Cie. [21] [22] Automobile manufacturers began research into turbocharged engines during the 1950s, however the problems of "turbo lag" and the bulky size of the turbocharger were not able to be solved at the time.
TDI is the combination of two existing diesel engine technologies: Direct injection — where a fuel injector sprays the diesel fuel directly into the main combustion chambers . This causes a more complete combustion process than using a pre-combustion chamber (known as indirect injection ), which therefore increases the torque output and ...
The Toyota WW engine family is a series of 16 valve DOHC inline-4 Common rail direct injection turbo diesel diesel engines with common rail injection. These engines are based on the BMW N47, [1] modified for use in Toyota vehicles, starting with the Verso in 2014.
