The Cat C4.2 engine with ACERT Technology optimizes performance and meets EU Stage IIIA emissions regulations. Together 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 delivers exceptional power, allowing more hydraulic pressure to drive productivity and reduce your cost per ton of material moved.

Fuel Economy

• Automatic Engine Control, Fuel Delivery and Manual Low Idle Function. A two level control with one touch command maximizes fuel efficiency and reduces sound levels during no-load or lighter-load conditions. 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 consequently, the carefully shaped combustion cycle lowers the combustion chamber temperatures, generates fewer emissions and thus optimizes fuel consumption. For you, this means more work output for the same amount of fuel consumed.
• Economy mode.. A new Economy Mode function, which is standard, enables you to adapt the performance of the machine to the work that needs to be done. By using a menu on the monitor, you can decide to switch the Economy Mode ON or OFF, and thus whether you want to operate fuel efficiently or whether you want to use the full power of the machine, in order to achieve maximum productivity.
• ODPS. On Demand Power Supply is a new feature, constantly regulating engine power supply, based on the power demanded by the hydraulic system. The machine reduces fuel consumption and machine noise in light duty applications.

Crankshaft and Pistons

A forged one piece, induction hardened crankshaft enhances balance, decreases vibration and improves abrasion resistance. Heat resistant aluminium alloy pistons have a short compression height for greater efficiency and longer life.

Electronic Control Module

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 data on conditions such as rpms, fuel consumption and diagnoses.

Outstanding performance

With a two percent increase in hydraulic pressure, which provides increased lift and breakout forces, the 314 D LCR's hydraulic system is designed for high efficiency and performance.

• Hydraulic snubbers at the rod end of the boom cylinders and at both ends of the stick cylinder cushion shock, reduce sound and increase cylinder life.
• Flow is reduced to a minimum when controls are in neutral in order to reduce fuel consumption and extend component life. Electronic underspeed control electronically adjusts pump output so that it doesn't exceed engine power, eliminating the need to reserve engine power to avoid engine stalls.
• The hydraulic cross sensing system contributes to improving productivity with faster implement speeds and quicker, stronger pivot turns.
• The two-pump combined function, now incorporated into the main control valve enables you to reduce your costs and machine downtime while modifying in the field.

ODPS (On Demand Power Supply)

During lighter load conditions that last for more than 5 seconds in the hydraulic circuit, ODPS automatically reduces engine speed to an RPM level equivalent to dial 9 in order to adjust the power to the load. Thanks to ODPS, your customers can save fuel by reducing consumption when the machine does not require high power. ODPS increases engine RPMs almost immediately when a heavier load (increased hydraulic pressure) is detected. In lighter load conditions, although the operator may notice a decrease in engine RPMs, note that the overall speed of the hydraulics cycle remains unchanged. Conversely, when ODPS delivers high power, the operator may notice an increase in engine speed. ODPS also participates to the overall machine sound level reduction.

Boom and stick regeneration circuits

The 314D LCR uses boom and stick regeneration circuits in order to save energy (fuel) during boom-down and stick-in operations. This function is electronically assisted for boom-down operations on the 314D LCR. How does it work? A combined system reduces engine speed and enables flow regeneration in the boom circuit during boom-down operations. The weight of the front parts is used to force the boom down, so that less flow is needed from the pump for boom-down operations. Therefore, more flow is available for other functions. Electronic regeneration is controlled by the machine and automatically becomes inactive when a tool is selected, in order to maintain the performance of the auxiliary hydraulic circuit. Thanks to this new design, hydraulic flow regeneration is increased, leading to faster operations and reduced pressure loss, and hence improved fuel efficiency.

Easy Operation

The 314 D LCR uses a boom priority circuit and a swing priority circuit. It has an automatic boom and swing priority function which selects the best mode, based on the amount of lever movement. This system eliminates the need for mode selection (Work mode and Power mode switches have been eliminated) and operators do not need to learn different modes, which simplifies operations and optimizes performance in different applications. As a result, smooth operations are ensured, and the machine is simpler and more agreeable to operate.

Medium Pressure Circuit

The Medium Pressure Circuit is available as an attachment for work tools requiring moderate hydraulic flow, such as rotating buckets or shears

High Pressure Circuits

The High Pressure Circuit is available as an attachment for work tools requiring high hydraulic flow or pressure, such as hammers, processors and shears.

Caterpillar uses advanced engineering and software to analyze all structures, creating a durable, reliable machine for the toughest applications. More than 70% 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.

Grease Lubricated Tracks

Grease lubricated track seals protect the track link and track pin and bushing inner wear and increase life by as much as 25 percent, when compared to dry seal undercarriages.

Compact Radius Design

The Compact Radius design of the 314 D LCR enable you to work in all sorts of jobsites, even very confined ones. Indeed, thanks to a shorter tail swing and tighter front swing radius, focus can be shifted on the work to do. The new 314D LCR is ideal for working lose to buildings, against walls, fences or embankments, wooded residential lots, road construction, and on generally crowded job sites. The tail swing radius is 1.48m, and, to further minimize the working envelope, the boom has been repositioned more towards the centre of the machine compared to a standard excavator. This reduces the front swing radius when the boom is pulled all the way up and the stick brought in completely. Thanks to this design, the risk of damage to the machine and any job site obstacles is significantly lower, which for you means lower operating costs, better resale value, increased safety and better operator comfort. Operators can work more confidently, therefore more efficiently, be assured that the counterweight will not swing into objects behind them.
