Generations of Experience



Emissions Challenge

Develop the bestcustomer solution

that meets theTier 3/ Stage IIIa

Option #1: Cooled EGR

Exhaust Gases are Re-introduced

Depleting the Oxygen DensityRecycled exhaust gas is externally

cooled



Cooled-EGR Experience

Cat Testing with Cooled EGR

Originally our path for truck

Never considered for non road

Selected one path - ACERT

Option #2: Internal EGR

Exhaust Gases are Re-introducedDepleting the Oxygen Density

By early opening of intake valvecapturing exhaust gas in manifold

before intake stroke

Cat Testing with Internal EGR

Effectively reduces engine

displacement

Significant impact on performance Very significant response impact

Concerns on engine wear

How will they get to Tier 3?

No after-treatment

Electronic controls

Common Rail or MEUI Multiple inj. & rate shaping

Combustion solutions Cooled EGR or Internal EGR

Valve overlapping using cam shape or VVA?

Internal Combustion Optimization

Intake Valve Actuation

Holds inlet valve open 3 mm (0.118) Controls intake valve timing BTDC

Not operational when engine oil temperature is below20 degrees C (68 degrees F)

Operational from 1100 - 2100 rpm @ 20 - 100% torque Hydraulic/electric device that holds the intake valves open

during the compression stroke until the ECM determines whento close the intake valves (between 120 and 53 degrees BTDC).

This reduces cylinder pressure during the compression stroke.

Coolant Flow Schematic Coolant FlowSchematic

JWPCJacket Water Pre-cooler used to cool the air before it enters the ATAAC.

Used to reduce the air temperature from the HP stage turbo. The JWAC is not used at low idle or under

low loads, the cooling system temperature would drop causing engine overcooling. The engine coolant

diverter valve is normally open.
