C11 Engine with ACERT® TechnologyA combination of innovations working at the point of combustion, ACERT® Technologyoptimizes engine performance while meeting U.S. EPA Tier 3 and European EU Stage IIIaemission regulations for off-road applications.

Cat® C11 Engine with ACERT® Technology The C11 engine provides a full-ratedgross power (SAE J1995) of 261 kW(350 hp) at 1800 rpm with a torque of1384 Nm (1024 lb/ft). The combinationof large displacement and high torqueallow the RM-300 to propel through thetoughest materials.

Mechanically-Actuated ElectronicallyControlled Unit Injection (MEUI)The MEUI fuel system is a uniquesystem that combines the technicaladvancement of an electronic controlsystem with the simplicity of directmechanically controlled unit fuelinjection. The MEUI system excels inits ability to control injection pressureover the entire engine operating speedrange. These features allow the C11 tohave complete control over injectiontiming, duration and pressure.

Multiple Injection Fuel DeliveryMultiple injection fuel delivery involvesa high degree of precision. Preciselyshaping the combustion cycle lowerscombustion chamber temperatures,which generates fewer emissions,optimizes fuel combustion; translatinginto more work output for your fuelcost.

C11 Cylinder BlockThe cylinder block is a one-piece, greyiron block that features generous ribbingfor stiffness and heavy bearingbulkheads for rigidity and strength asthe crankshaft turns. This new designsupports the engine’s highercompression ratios and increases itspower density. The incorporation ofstraight-thread, o-ring connection pointsreduces the loss of engine oil and fluids.

High Cylinder PressuresHigh cylinder pressures combined withtightly controlled tolerances promoteextremely efficient fuel burn, less blowby and lower emissions.

Single Overhead CamOne single overhead cam is driven by agear on the flywheel end of the engine.Placing the cam gear at the flywheel endsignificantly reduces noise andvibration. To reduce wear, a pendulumabsorber is mounted at the front of thecamshaft. Together these two featurescontribute to the long-life and durabilityof this engine.

Service, Maintenance and RepairEasier service, maintenance and repair isaccomplished by monitoring keyfunctions and logging critical indicators.Advanced electronic diagnosticcapabilities are possible using CatElectronic Technician.

Turbocharged and Air-to-AirAftercooling (ATAAC)The turbocharged air-to-air aftercoolingsystem provides high horsepower withincreased response time while keepingexhaust temperatures low for longhours of continuous operation.

Air-to-Air AftercoolingAir-to-air aftercooling keeps air intaketemperatures down and in concert withthe tight tolerance combustion chambercomponents, maximizes fuel efficiencyand minimizes emissions. Newturbocharger, unique cross-flow head,single, rear driven, overhead cam and amore efficient intake manifold generatesignificant improvements in air flow.This generates significantimprovements in efficiency and reducedemissions.

ADEM™ A4 Electronic Control ModuleThe ADEM A4 electronic controlmodule manages fuel delivery, valvetiming and airflow to get the mostperformance per gallon (liter) of fuelused. The control module providesflexible fuel mapping, allowing theengine to respond quickly to varyingapplication needs. It keeps track ofengine and machine conditions whilekeeping the engine operating at peakefficiency.
