Komatsu and Cummins Engine Models

EPA Tier 3 Requirements• Background of development• Reduction of NOx is the main target for EPA Tier 3

Combustion temperatures UP

It tends to generate NOx

Combustion temperatures DOWN Many PM by

imperfect combustion

Trade-off between NOx and PM

(Less NOx = More PM, Less PM = More NOx)

Needs some key technologies to find a way out of the deadlock…

The Komatsu SAA4D95LE doesn’t just contradict conventional thinking about compact power- it re-writes the rules.

This new engine moves beyond the capability of other 3.3 liter engines to offer the same 92.5 hp associated with the 4.0 to 4.5 liter engine class, but now with an engine package more than 30% smaller and lighter.

The SAA4D95LE achieves this by combining our compact 3.3 liter platform with the performance enhancing technology of advanced electronics and HPCR similar to that found in the larger 6-cylinder Komatsu SAA107E-1. (EX50 Model Family)

As a result, power is increased by around 30% and peak torque by 40% without impacting fuel consumption.

Komatsu SAA4D95LE

Komatsu -Cummins Off-Highway TechnologyCommitted to Customer NeedsWhile we have taken the necessary measures to meet EPA emission requirements, our first commitment is to deliver great reliability, durability and cost-effectiveness on all diesel engine products.

Evolution of Off-Highway StandardIn 1996, the first emission regulations went effect in the US, and were mirrored three years later in Europe. Several countries regulate emissions of PM and NOX. PM and NOX, are the primary pollutants in diesel exhaust, as CO and HC are low in diesel.

Future regulations call for NOX and PM levels 98% below previous unregulated levels beginning in 2011. Advanced after treatment devices, such as Selective Catalytic Reduction (SCR) and Active Diesel Particulate Filter (DPF) may be needed to achieve these extremely low emission levels.

Advanced R & D allows transfer of technology to design the right emissions solution, bringing optimum value for the customer.

Fuel Standards – Tier 3In meeting the new emission requirements, diesel fuel is a critical part of the solution. First, sulfur level of 500-ppm maximum began 2007. In 2010 the sulfur in non-road diesel fuel will be further reduced to a maximum of 15-ppm.

Because ultra-low sulfur fuel is necessary for most after treatment technology, use of higher sulfur will be prohibited in 2011 and later model years.

Lubricating OilThe engine lubricating oil is another important factor in meeting future emission regulation. New specifications are being developed to be compatible with low emissions solution for Tier 4.

Tier 3 NOX Emission Reduction• Looked at all feasible options and decided to

concentrate on advanced combustion technology

• Key areas of design to maximize combustion:– Power cylinder / Air-Handling / Fuel and Control

System• Design process that uses advanced computer

simulation of the combustion event in order to maximize combustion and reduce NOX and PM

Advanced Combustion Solution

• By modeling combustion reactions anywhere in the cylinder critical design parameters were controlled and modified

• Optimization of the combustion system met Tier 3 requirements without the need for oxidation catalysts

• Komatsu –Cummins Tier 3 advanced combustion solution provides stable equipment architecture through 2015!!

Heavy Duty HPCR (High Pressure Common Rail) System

Advanced Heavy duty HPCR system is used for optimum, emission solutions and performance.

Full electronic control over the fuel injection event in relation to timing, quantity, pressure and number of injection events is a must for optimum solutions and performance.

Electronics Control System

The electronic control of the engine system is a critical element in meeting emissions standards.

More stringent regulations require very precise control of engine, fuel, air-handling and after treatment systems.

Komatsu construction applications have proven reliability with a very robust electronic system for very dependable operation.

Komatsu -Cummins Off-Highway TechnologyTier 3 StandardsTier 3 emission standards have been phased in beginning as early as 2008 in the US.

Tier 3 standards focus on the reduction of NOX、roughly 40% reduction is required from Tier 2 level. PM level was not changed from Tier 2 levels.

Tier 4 and the FutureThe phase-in of after treatment-forcing standards will begin in 2011 in Europe and the US. PM filter will be required for several power categories to meet 0.02 –g/kW-hr standard.

High efficiency NOX after treatment will be required beginning in 2014.

“Low Total Operating Cost”

• Reduced fuel consumption• CLSS (Closed-center Load Sensing system)• Lower Total Operating Cost• New Komatsu diesel engine• New Nissan gasoline engine

• 3.3-litre SAA4D95LE-5-A engine in order to save fuel• CX50 accomplish super low fuel consumption while

keeping truck performance high• How does CX50 keep fast cycle times while

achieving excellent fuel consumption?

The answer is CLSS!

Lower Fuel Consumption20%

Fuel savings!6.5 ton/year

CO2 saving!

Komatsu tested data. FD50AT-10 compared to FD50AT-8. The results may vary depending on conditions

CO2 emission is calculated by Japanese figure.

CLSS (Closed center Load Sensing System)

*: “Necessary” means

1)No hyd/ steering operation

2)At lifting/ tilting stroke end

• Variable displacement pump incorporates a Load Sensing (LS) Valve• LS valve detects the load and determines proper oil flow. Variable

displacement pump discharges just enough oil to meet the need.• Unless necessary*, hyd. oil circuit is “Closed”. No oil flow. Engine-load is

much smaller than with a conventional hydraulic system.• CLSS minimizes engine load and oil pressure losses within the system

Easy Maintenance Design

Hydraulic Fuel

• Sensor-equipped reserve tank• Provided with a level sensor, the reserve tank

allows the operator to check the coolant level through the control panel

• One-piece, thick plate welded chassis

• Reinforcement of stress points against stationary steering, turning, and unevenness of the yard

• 10 to 16-ton common outer rails and with one-piece molded rail structure improve its rigidityRail & roller

Highly Rigid Mast Construction

• Gasket sealed rear-axle king pin• The king pin fulcrum is bolted to provide

a gasket sealed structure, which ensures superior durability of rear axle

Proven front/rear axlesFront axle● Interposed pinion shaft bearing was employed.● Highly durable differential bushings and spiders● A thick differential casing● Proven hub/carrier/cover securing method● A snap ring added to the hub seal assembly to

prevent the seal from coming undone

Rear axle● One PS cylinder secured inside the rear axle● Decrease of steering angle differences　 reduced slippage during turning, which

improves the life of the tires.● Highly durable bearings
