Agenda

CAT Industrial Engines

Fuel quality concerns

Benefits of electronic injection

What the C4.4, C4.4 ACERT / C7.1, C7.1 ACERT replaces

3




Emissions Legislation is changing, but Tier 3/Stage IIIA

Equivalent and Below Represents a Large Global Opportunity

5




Cat® Industrial Engines Provide an Opportunity for using

many different Applications

Crane

Combine harvester

Agriculture Construction Industrial

What applications are you aware of?

Crop sprayers

Crop harvesters

Sewage pumps

Storm pumps

Drain pumps

Ski lifts

Lift shafts

Well head machines

6




What is an Opportunity? Reasons for the Customer to Change Engine

Recent focus Emissions standards force change

What else … Technology change required

Next generation machine design or derivative of generation design

End user customer requirements change; power, performance, fuel consumption

Cost reduction challenge at OEM (lifetime engine value focus)

OEM finds new markets, exporting to new markets

Create a machine for an emissions territory rather than one for all

How can we support you better?

Agenda





15




Variation in Diesel Fuel Quality - Example

Fuel surveys taken from Filling Stations

Multiple stages of filtration are required

Internal EGR is more suitable for the

market.

Common Rail fuel system are effected more

than Mechanical fuel systems

16




Fuel Quality at End User Site is Variable High Efficiency Filtration is required to Maximise performance

Fuel Storage is inconsistent!

Filtration is key to protection of engine

China Wuxi area: filter duration circa 340 hours

17

Mechanical

Mechanical fly-weight governors

Mechanical or electronic speed governing

Rotary fuel pump

Traditional mechanical way to control fuel injection

Rotary pump , more accurate fuel injection than in-line

pump and improves engine performance

Set in position for optimum performance

ECU (Electronic Control Unit) with electronic sensors and actuators or solenoids

High pressure common rail

Common rail fuel pump

Via accurate fuel injection to optimise combustion in order to improve engine performance and fuel consumption

Interface with vehicle systems and carries out self monitoring and diagnostics

Additional functions

Cold start and overheat engine protection

Remote engine shutdown e.g. crane rollover

Constant engine speed irrespective of load e.g. PTO

Electronic

Electronic Control – the Difference

21




Benefits of Electronically Controlled Engines

Meet emission standards

Provides ability to meet NOx and Particulate emissions standards at power levels when a mechanical

product would not be compliant

Matching engine to application

Enhanced performance through electronic control, load acceptance, SFC mapping, transient response

Engine for premium OEM products where engine to machine integration can provide value in terms of

response, speed control, transmission control, etc

Speed/governing control can align to application; excavator, genset, compressor, tractor, loading

Machine improvements

CAN network for control system and instrument cluster providing feedback to operator

De-rate strategy provides engine protection for oil and water temperature with operator feedback

through warning interface.

Demand fans matched to machine operation saving on noise and fuel consumption

Improved altitude and cold start capability
