The C11 engine provides a full-rated gross power (SAE J1995) of 261 kW (350 hp) at 1800 rpm with a torque of 1384 Nm (1024 lb/ft). The combination of large displacement and high torque allow the RM300 to propel through the toughest materials
Mechanically-Actuated Electronically Controlled Unit Injection (MEUI)
The MEUI fuel system is a unique system that combines the technical advancement of an electronic control system with the simplicity of direct mechanically controlled unit fuel injection.
The MEUI system excels in its ability to control injection pressure over the entire engine operating speed range. These features allow the C11 to have complete control over injection timing, duration and pressure.
Multiple Injection Fuel Delivery
Multiple injection fuel delivery involves a high degree of precision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, which generates fewer emissions, optimizes fuel combustion; translating into more work output for your fuel cost.
C11 Cylinder Block
The cylinder block is a one-piece, grey iron block that features generous ribbing for stiffness and heavy bearing bulkheads for rigidity and strength as the crankshaft turns. This new design supports the engine's higher compression ratios and increases its power density. The incorporation of straight-thread, o-ring connection points reduces the loss of engine oil and fluids.
High Cylinder Pressures
High cylinder pressures combined with tightly controlled tolerances promote extremely efficient fuel burn, less blow by and lower emissions.
Single Overhead Cam
One single overhead cam is driven by a gear on the flywheel end of the engine. Placing the cam gear at the flywheel end significantly reduces noise and vibration. To reduce wear, a pendulum absorber is mounted at the front of the camshaft. Together these two features contribute to the long-life and durability of this engine.
Service, Maintenance and Repair
Easier service, maintenance and repair is accomplished by monitoring key functions and logging critical indicators. Advanced electronic diagnostic capabilities are possible using Cat Electronic Technician.
Turbocharged and Air-to-Air Aftercooling (ATAAC)
The turbocharged air-to-air aftercooling system provides high horsepower with increased response time while keeping exhaust temperatures low for long hours of continuous operation.
Air-to-air aftercooling keeps air intake temperatures down and in concert with the tight tolerance combustion chamber components, maximizes fuel efficiency and minimizes emissions. New turbocharger, unique cross-flow head, single, rear driven, overhead cam and a more efficient intake manifold generate significant improvements in air flow. This generates significant improvements in efficiency and reduced emissions.
ADEM™ A4 Electronic Control Module
The ADEM A4 electronic control module manages fuel delivery, valve timing and airflow to get the most performance per gallon (liter) of fuel used.

Additional operator comforts include two cup holders and a 12-volt power receptacle. The cab is also radio-ready and includes a power converter, antenna with cable, two speakers and a headliner location for mounting radio.
Exceptional Viewing Area
The cab offers an exceptional viewing area to the front tire edge, mixing chamber and to the rear wheels.
Hydraulically Engaged Clutch, High Torque Mechanical Transmission and Drive Axle
Hydraulically engaged clutch, high torque mechanical transmission and drive axle allows efficient and reliable transfer of engine power to rotor and is sized to handle tough cutting and deep mixing.
Rugged Drive Chains
Rugged drive chains provide efficient, continuous power to the rotor. Single strand heavy-duty chain resists breakage.
Three Rotor Speeds
Three rotor speeds for maximum performance in a variety of materials and cutting depths. First speed is used primarily for pulverizing the material. Second and third rotor speeds can be used as blending or mixing passes.
High capacity rotor driveshafts and maintenance-free universal joints.
Heavy-Duty Shear Disc Or Optional Torque Limiter
Heavy-duty shear disc or optional torque limiter protects rotor drive components from torsional stress and shock loads.
Designed to produce maximum breakout force, the Universal Rotor 41 cm (16") performs well in severe asphalt cuts. It also cuts existing soil cement.
Universal Rotor 46 cm (18") for Soil
The Universal Rotor 46 cm (18") is designed to provide maximum mixing depth and has lower breakout force compared to the Universal Rotor 41 cm (16"). This rotor meets European 45 cm mixing depth requirements while providing the highest level of material pulverization and gradation.
Maximum cutting depths: 41 cm (16") or 46 cm (18")
Chevron-pattern bit arrangement
Bolt-on Breakaway bit holders
200 carbide-tipped bits
Abrasion-resistant steel kicker paddles on every stand-off
Designed for deep-cut soil mixing where pulverization and gradation is of lesser importance than higher working speeds. Performs well in cohesive soils and has a secondary application of surface mining for non-engineered substances such as coal, shale, or limestone.
The Spade Rotor blends additives with cohesive, semi-cohesive or granular materials. 58 carbide-faced quick change spade tools provide long service life and are easily replaced due to a single nut and bolt connection. This design allows the tool to break away if it strikes a solid object, preventing damage to the rotor and the rotor drive train.
Cooling package is a multi-row modular design, stacked in series for easy access for cleaning and service. A modular stacked cooling system provides more efficient cooling of individual systems and makes replacement and routine cleaning easier. Electronically controlled on-demand variable speed cooling fan provides the lowest overall noise levels and high ambient operation capability.
