Now HPI features new injection nozzles precisely dosing the supply of fuel and operating at a pressure of up to 200 bar in the combustion chambers. (ausmotive.com)
They changed the fuel injection nozzles and fitted the crossover with a low - inertia variable geometry turbocharger. (automotorblog.com)
Regardless of fuel system design, a mechanical diesel fuel injection system and rapid rise of fuel pressure and flow will result in injection nozzle opening pressure being reached more rapidly and also earlier in the 4 - stroke cycle with more precise fuel delivery, more precise injection timing and built - in timing advance.
