1. Tips For Improvement

2. IT ALL STARTSWITHYOU 3Steps to Limiting IDLE TIME Turn it off at lunch and breaks Avoid idling more than 5 minutes Limit cool down periods to 3 minutes

3. IdlingShortens EngineLife • Diesel engines are designed to operate best at operating temperatures • At Idle • Cylinder temperature drops leading to incomplete combustion • Carbon builds on valves, head, rings, and pistons • Lower combustion pressures allow blow by and contribute to oil degradation According to the IDEM*,“Running an engine at low speed (idling) causes twice the wear on internal parts compared to normal use” *Indiana Department of Environmental Management

5. IT’S A NEW DAY Idling Born of Necessity … But No Longer NECESSARY Origins of the “let it idle” practice The early diesel environment Heavy rotating masses Mechanically controlled injection Pre-combustion chambers Thicker oils Cheap fuel Unreliable starters and batteries Fuel gelling in cold weather Inefficient cab heating / cooling systems = Need to let it run, little trust in restarting Reasons to change behavior The modern diesel environment Lighter / stronger rotating masses State-of-the-art electronic fuel systems More robust batteries Premium multi-viscosity oils Expensive fuel Advanced / reliable starters Summer and winter blend fuels Vastly improved heating and cooling systems = No need for “convenience” idling

6. NEXT STEPSIN OPERATING EFFICIENCY Work the machines, they’re built to work Use economy “E” mode, whenever possible Reduce high speed travel (track machines) Avoid operating at hydraulic relief Eliminate wheel spin Minimize non-productive movement
