Common-rail Cayenne Diesel

Porsche Cayenne Diesel - Common-rail

Common-rail

On the Cayenne Diesel, direct fuel injection comes courtesy of a common-rail injection system. The injection pressure is now up to 29007 psi ensuring optimum distribution of the air/fuel mixture – for greater performance. The piezoelectric injectors provide flexible injection rate adjustment, using exactly metered quantities of fuel, with multiple injections for each power stroke to deliver smooth combustion.
