Common-rail SyStem

Kohler has selected the most advanced common-rail system available on the market and specifcally

engineered or extreme durability and longevity within arduous industrial and construction equipment

applications. The 2000 bar high pressure pump, together with the advanced multiple-injection control

o the solenoidinjectors, allows an excellent uel rate control during the injection process.

turboCharger and Charge-air Cooler

The wastegated turbocharger has been specifcally tuned to minimize the turbolag response andprovide the precise volume o air or an excellent low end torque capability. The special design othe lubrication system guarantees extended durability o the turbocharger. The use o a charge aircooler is required to ensure the correct air inlet temperature or the optimal engine perormancewhilst achieving emissions compliance.

4 valveS

The 4 valves per cylinder design has been selected to enable the installation o the injectors precisely

on the cylinder axis and centred with the combustion bowl. This solution allows or a symmetricaluel atomisation and distribution within the combustion bowl ensuring optimal mixing o uel and air.The design o the combustion bowl itsel together with the inlet ports shaping, have been studied and

developed with CFD analysis to complete the absolute optimization o the combustion process.
