The engine gained new 29,000 PSI piezo injectors as well as a completely reworked fuel system which was now powered by the Bosch CP4 pump, that also now supports up to 20% biodiesel mixtures and a urea injection (to reduce nitrogen oxides) with a 5.3 gallon DEF tank. This engine has a fuel injector in the exhaust tract, to allow raw fuel ...
High-pressure common-rail, Bosch CP4.2 injection pump, piezoelectric injectors Engine: Power Stroke 90° V8 Displacement: 6.7 L (406 cu in) Bore and stroke: 3.9 in × 4 + 1 ⁄ 4 in (99.1 mm × 108.0 mm) Block: Compacted graphite iron Heads: Aluminum (reverse flow) Pistons: Hypereutectic piston: Valvetrain:
The direct injection pump is a Bosch CP4 with two heads, helping to produce torque of around 400 N⋅m (300 lb⋅ft) even at low engine speeds. The D3/D4 bore remains the same as in the D5, but with a 77 mm (3.0 in) stroke the displacement is brought down to 1,984 cc (121.1 cu in), keeping it below the vital two-litre threshold in many countries.
Bosch 2,000 bar (29,010 psi) common rail (CR) (one rail per cylinder bank) direct injection: with two chain-driven high-pressure fuel pumps, fuel cooler for return line, twelve combustion chamber-sited eight-hole (0.12 mm (0.0047 in)) piezo injectors with multi-pulse injection (up to five injection operations per piston cycle, including pre ...
Injection pump for a 12-cylinder diesel engine. An injection pump is the device that pumps fuel into the cylinders of a diesel engine.Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt) that also drives the camshaft.
Common rail fuel system on a Volvo truck engine. In 1916 Vickers pioneered the use of mechanical common rail systems in G-class submarine engines. For every 90° of rotation, four plunger pumps allowed a constant injection pressure of 3,000 pounds per square inch (210 bar; 21 MPa), with fuel delivery to individual cylinders being shut off by valves in the injector lines.

A Fuel pump is a component used in many liquid-fuelled engines (such as petrol/gasoline or diesel engines) to transfer the fuel from the fuel tank to the device where it is mixed with the intake air (such as the carburetor or fuel injector).
The Volkswagen-Audi V8 engine family is a series of mechanically similar, gasoline-powered and diesel-powered, V-8, internal combustion piston engines, developed and produced by the Volkswagen Group, in partnership with Audi, since 1988.
