8 CWI Combustion Technology Spark Ignited Stoichiometric with Cooled EGR Spark Plug Stoichiometric EGR (SEGR) Three Way Catalyst Architecture Three Way Catalyst Spark Ignited Fuel, EGR and air are premixed outside the cylinder Spark plug ignites the mixture Charge Air Cooler EGR Cooler Fuel Air flow controls fuel flow Throttle Air/Fuel ratio controls emissions 8

9 What is Stoichiometric Combustion? Ideal combustion process where fuel is burned completely Ideal air/fuel ratio - chemically correct mixing of fuel and air Consumes all fuel & air without excess of either in exhaust No Oxygen in exhaust stream allows Three Way Catalyst to handle NOx control Benefits: Increased power density Increased thermal efficiency Decreased emissions 9

10 Three Way Catalyst TWC reduces three harmful emissions: NO X, CO, HC End products are: N 2, CO 2, H 2 O Packaged as part of muffler Simple, passive device O 2 Sensor connects to ECM Consistent performance across all duty cycles Catalyst Inlet NO X CO HC Catalyst Outlet N 2 CO 2 H 2 O ISL G / ISX12 G TWC

The default interval is the hours shown. Perform maintenance at hours, distance, or months indicated, whichever comes first Refer to the Owners Manual for complete details on Maintenance Intervals ¹ If the engine is equipped with an optional coolant filter, the coolant filter will need to be replaced at the same intervals as the oil filter. Regardless of whether the engine is or is not equipped with a coolant filter, SCA/DCA additive levels must be checked according to the interval listed in the Owners Manual. * Assuming normal duty cycle/based on 12 mph average speed. ** Do not change if SCA above 3 *** Initial Overhead Adjustment at 1,000 hours.

23 Keys to Success Follow Cummins maintenance intervals and procedures outlined on QuickServe On Line or in Operation and Maintenance manuals Use Cummins Authorized parts Set oil drain / service intervals based on average fleet speed Default interval is the hours stated. Interval is Defined by application and average speed hours, miles or time, which ever comes first Example: Oil Drain/Service Intervals Average Vehicle Speed Kilometers Miles Hours Months Truck 30 mph 24,000 15, Transit Bus mph 9,650 6, Refuse Truck mph 9,650 6, Use only natural gas engine oil per Cummins Specification (CES ) Check air intake every 250 hours, and use only OEM approved air filters Check/drain fuel filter daily Visually check coolant recovery tank level daily. Perform Initial Overhead Valve adjustment at 1,000 hours

31 Refuse Trucks Customers

32 Waste Management Refuse Trucks WM has 18,000 Class 8 collection trucks 2,000 natural gas trucks on the road today - the largest fleet of heavy duty natural gas trucks in N. America

33 WM s CNG Fleet Goals WM will continue replacing diesel powered refuse collection trucks with natural gas ones Plans to purchase more trucks in 2013 Convert almost 100% of refuse collection trucks by 2020 WM will build 25 natural gas fueling stations each year WM investing in public fueling stations at most sites

34 Republic: CNG Conversion Appoximately 9% of current fleet uses natural gas. CNG is preferred technology Lower fuel costs support conversion Competitive advantage Capital required for extra cost and infrastructure Gradual conversion as older trucks are replaced Approximately 50% of the 2013 truck purchases are CNG

35 New Website launched May 1, 2012 Great source of information about natural gas engines and vehicles. Features the Natural Gas Academy, a series of instructional videos Designed to provide a general overview of natural gas as a fuel whether it is compressed (CNG) or liquefied (LNG), and how it is used with vehicles.
