Cat® C11 Engine with ACERT® Technology -
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 -
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. The control module provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. It keeps track of engine and machine conditions while keeping the engine operating at peak efficiency.
