DIESEL (E 23/E 23B)
The E 23 has met the challenges of increasingly stringent global
emissions standards through continuous optimization of its
proven design. With only minor engine changes, and avoiding
high cost technologies such as common rail fuel injection,
the E 23B uses proven SCR technology to meet US EPA Tier 4F
and IMO III, enabling maximum confidence and minimum risk inyour daily operations.
Progress Rail leads the industry in alternative fuels, supporting
global customers who run the highest fleet-wide blends ofbiodiesel in revenue service.
Biodiesel
The approved use of up to 20% biodiesel blend for EMD® 645
and 710 series engines helps customers achieve their aggressive
decarbonization goals.
Renewable Diesel
Hydrotreated Vegetable Oil - HVO, or Renewable Diesel isconsidered a dropin replacement for diesel fuel. HVO/RD fuels
are renewable, which can reduce the carbon footprint orGreenhouse Gas (GHG) impact of the engine.

PERFORMANCEADVANTAGE
SUPERIOR
TRANSIENT RESPONSE.

Cool, high density charge air delivered to the E 23cylinders across the entire operating range enables
rapid power response regardless of the operating point.
This allows the E 23 to accelerate from idle(200 RPM) to 100% continuous load and speed(900 RPM) in approximately 13 seconds.

4BEST IN-CLASS TRANSIENT RESPONSE•

E 23 offers the performance of a high speedengine with the durability advantage of amedium speed engine.

•Ample power margin throughout the entireoperating speed range allows for optimized
engine sizing and a single speed reduction gear.

•Avoids engine lugging under demandingvessel maneuvers.

•Accepts 100% block load in constant
speed applications.

TOTAL COSTOF OWNERSHIPADVANTAGE
MAXIMUM UPTIME.

PARTS • LABOR • FLUIDS
Downtime is expensive. EMD® engines are designed tominimize the amount of time needed for maintenance andrepairs in order to maximize your productivity, keeping
operational costs to a minimum.

• Reduced fuel consumption over previous models due toEPA T4F / IMO III technologies and low idle speed.
• Easy non-invasive inspection of cylinder components for
simple condition-based maintenance.
• Simple overhauls to minimize downtime — Power Assembly(head, liner, piston, rod) can be removed and replaced as one
unit in under 4 hours.
• Closed loop dosing control system optimizes Diesel Exhaust
Fluid (DEF) usage.

8• No oil change required between overhauls unless indicatedby oil sample analysis.

Quantifying ownership costs for the purposes ofengine selection and budgeting is a challenging
task. In order to simplify this process, a Total Cost ofOwnership (TCO) report is available for your planningand comparison needs. The analysis considers manyfactors including:• Duty-cycle impacts.
• Preventative maintenance parts and labor.
• Economic factors such as commodity priceand inflation.
• Labor estimates for all activities.

CATERPILLARSOLUTIONS/EMD ENGINESCOMPREHENSIVE SOLUTIONS

As a product in the expansive Caterpillar® Marine
portfolio, the EMD engine is also available andcompatible with many CAT® Marine vessel solutions,
including:• CAT Connect technologies such as Marine AssetIntelligence.
• SOS oil sampling and analysis services.
• Local engine alarm/control panels and remote
displays.
