Before entering the suction chamber of the injection pump, the fuel is cleaned in a two-
stage, parallel or changeover filter.
Turbocharger (D 2866 TE, LE, LXE)
The exhaust gases of the engine are passed through the turbine rotor of the turbochar-
ger. Air impeller mounted on the same shaft draws in fresh air and delivers it at a higher
pressure to the cylinders.
The turbocharger is air-cooled or liquid-cooled. Lubrication of the main bearing is by oil
under pressure from the engine lubricating system.
