Clean, quiet operation and superior power with ACERT Technology.
The Cat C4.2 engine with ACERT Technology
The Cat C4.2 engine with ACERT Technology optimizes performance and meets EU Stage IIIA regulations. In conjunction with integrated electronics, ACERT Technology reduces emissions during the combustion process by using advanced technology in the air and fuel systems. The Cat C4.2 engine has five percent more power than the former engine, allowing for more hydraulic pressure and increased productivity.Automatic Engine Control and Fuel Delivery
A three-stage control with one-touch command maximizes fuel efficiency and reduces sound levels. Fuel delivery is managed by the ADEM™ A4 Engine Controller for the best performance per liter of fuel used. Flexible fuel mapping allows the engine to respond quickly to varying application needs. Electronic controls govern the fuel injection system. Multiple injection fuel delivery involves a high level of precision and by precisely shaping the combustion cycle lowers combustion chamber temperatures, generates fewer emissions and optimizes fuel combustion. This means more work output for your fuel cost.Prior to starting the machine, the system checks for low engine oil, hydraulic oil and engine coolant fluid levels and warns the operator through a color Liquid Crystal Display (LCD) monitor.

Available as a standard feature, economy mode allows you to balance the demands of performance and fuel economy while maintaining the breakout forces and lift capacity enjoyed at standard power.Electronic Module Control (ECM)
The ECM works as the "brain" of the engine's control system, responding quickly to the operating variables to maximize engine efficiency. Fully integrated with sensors in the engine's fuel, air, coolant and exhaust systems, the ECM stores and relays information on conditions such as rpm, fuel consumption and diagnostics.Air Cleaner
The radial seal air filter features a double layered filter core for more efficient filtration. A warning is displaced on the monitor when dust accumulates above a preset level.
High efficiency and performance with low effort and precise control.
Outstanding Performance Boom and Stick Regeneration Circuit
With two percent more hydraulic pressure for additional lift, swing torque and breakout forces, the 315D L hydraulic system is designed for high efficiency and performance. Auxiliary hydraulic and electrical lines are routed to the boom foot making installation of hydraulic circuits much easier. The new compact design utilizes shorter tubes and lines, reducing friction and pressure drops, resulting in a more efficient use of power.
- Hydraulic snubbers at the rod end of the boom cylinders and both ends of the stick cylinders cushion shock, reduce sound and increase cylinder life.
- Flow is reduced to a minimum when controls are in neutral to reduce fuel consumption and extend component life.
- Electronic Under Speed Control electronically adjusts pump output to not exceed engine power preventing the need to reserve engine power to avoid engine stalls.
- Hydraulic Cross-Sensing System uses two hydraulic pumps to 100 percent of engine power under all operating conditions, improving productivity with faster implement speeds and quicker, stronger pivot turns.
The boom and stick regeneration circuit saves energy during boom-down and stick-in operation, increasing efficiency and lowering operating cost.Easy Operation
Work mode and power mode switches have been eliminated making full power available at all times. Operators do not need to learn different modes, an automatic boom and swing priority function automatically selects the best mode based on joystick movement.
Undercarriage and Structures
Excellent stability and maneuverability.
Advanced Engineering and Software
Caterpillar uses advanced engineering and software to analyze all structures, creating a durable, reliable machine for the toughest applications. More than 70 percent of the structural welds are robotic and achieve over three times the penetration of manual welds. These structural components and undercarriage are the backbone of the machine’s durability.aCarbody Design
X-shaped, box section carbody provides excellent resistance to torsional bending. Track roller frames are press-formed, pentagonal units that deliver exceptional strength and service life. Integral to the track roller frame are the standard idler and center guards, which help maintain track alignment when traveling or working on slopes.Cross Roller Bearing
A cross roller bearing design in the swing bearing gives more surface contact to absorb stresses from high swing torque offered by Caterpillar. This design provides exceptional machine stability and reduces machine pitching during boom down operation.Travel Motors
Travel motors with automatic speed selection let the 315D L automatically change up and down from high and low speeds in a smooth, controlled manner.
Performance, reliability and durability.
Built for performance and long service life, Cat booms and sticks are welded, box-section structures with thick multi-plate high strength steel fabrications. The 315D L offers one boom with four different stick options.Intermediate Stick
A new 2.9 m stick is available to provide long reach and increased digging and lifting capability. When equipped with a coupler or large bucket the new stick will increase overall performance and productivity.Boom
