Tips For Improvement

IT ALL STARTS WITH YOU 1 Turn it off at lunch and breaks 2 Avoid idling more than 5 minutes 3 Limit cool down periods to 3 minutes 3 Steps to Limiting IDLE TIME

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 *Indiana Department of Environmental Management Idling Shortens Engine Life According to the IDEM*, “Running an engine at low speed (idling) causes twice the wear on internal parts compared to normal use”

How Much Does 1 Hour of IDLE TIME Cost*? For a 20 T Excavator: *Indiana Department of Environmental Management IDLING IS COSTLY

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 IT’S A NEW DAY Idling Born of Necessity … But No Longer NECESSARY

1 Work the machines, they’re built to work 2 Use economy “E” mode, whenever possible 3 Reduce high speed travel (track machines) 4 Avoid operating at hydraulic relief 5 Eliminate wheel spin 6 Minimize non-productive movement NEXT STEPS IN OPERATING EFFICIENCY
