2. Turbo-diesel - Wikipedia

   en.wikipedia.org/wiki/Turbo-diesel

   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.

3. Turbocharger - Wikipedia

   en.wikipedia.org/wiki/Turbocharger

   In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement .

4. Variable-geometry turbocharger - Wikipedia

   en.wikipedia.org/wiki/Variable-geometry_turbocharger

   Volvo FM VGT diesel engine with EGR emissions technology. Variable-geometry turbochargers (VGTs), occasionally known as variable-nozzle turbochargers (VNTs), are a type of turbochargers, usually designed to allow the effective aspect ratio (A/R ratio) of the turbocharger to be altered as conditions change. This is done with the use of ...

5. Ford Power Stroke engine - Wikipedia

   en.wikipedia.org/wiki/Ford_Power_Stroke_engine

   The first engine to bear the Power Stroke name, the 7.3 L Power Stroke V8 is the Ford version of the Navistar T444E turbo-diesel V8. Introduced in 1994 as the replacement for the 7.3 L IDI V8, the Power Stroke/T444E is a completely new design, with only its bore and stroke dimensions common with its predecessor (resulting in its identical 444 ...

6. TDI (engine) - Wikipedia

   en.wikipedia.org/wiki/TDI_(engine)

   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 ...

7. BMW N57 - Wikipedia

   en.wikipedia.org/wiki/BMW_N57

   The BMW N57 is a family of aluminium, turbocharged straight-6 common rail diesel engines. The engines utilize variable geometry turbochargers and Bosch piezo-electric injectors. [ 1 ] The engine jointly replaced the M57 straight-6 and M67 V8 engines.
