This breakthrough technologyreduces emissions during the combustionprocess by using advanced technologyin the air and fuel systems, in conjunctionwith integrated electronics. ACERTTechnology enhances overall engineperformance while dramaticallyreducing exhaust emissions.

Fuel Delivery. The C9 engine withACERT Technology uses multipleinjection fuel delivery to precisely shapethe combustion cycle. Several smallignitions lower combustion chambertemperatures, generates fewer emissionsand optimizes fuel combustion. Bottomline: more work output for your fuel cost.

Power Management. The 160M PowerManagement System automaticallydelivers an additional five horsepowerin each forward gear 1st through 4th,and each reverse gear 1st through 3rd.This standard feature optimizes rimpullfor all gears by balancing traction, speedand horsepower while conserving fuel.The system limits horsepower in lowergears, which helps reduce wheel slipwhere traction is limited. With theVariable Horsepower Plus (VHP Plus)option, an additional five-horsepoweris delivered in each forward gear 5ththrough 8th for more power athigher speeds.

Performance. The Cat C9 engine meetsspecific performance requirements for160M applications. Its superior torqueand lugging capability can pull throughsudden, short-term increases in loads,maintaining consistent, desirable gradingspeeds to get the work done faster withoutdownshifting.

Predictable movements

Consistent and Predictable Movement.PPPC valves have different flow ratesfor the head (red) and rod ends (blue)of the cylinder. This ensures consistentextension and retraction speeds foreach cylinder, and gives the operatora consistent and predictable responseevery time an implement control is moved.

Balanced Flow. Hydraulic flow isproportioned to ensure all implementsoperate simultaneously with little effecton the engine or implement speeds.If demand exceeds pump capacity, allcylinder velocities are reduced by thesame ratio. The result is improvedproductivity in all applications.
