33. 33 EPA Regulations – Tier 3 Tier 1through Tier 4 regulations are a part of the EPA’s Clean Air Act, enacted to reduce emissions of specific pollutants produced by diesel engines. Starting in 1996 the EPA introduced a progression of 4 Tiers of emissions regulations, each Tier further reducing emissions of specific pollutants. Diesel engine emission regulations are also specific to the engines in particular power categories. Husqvarna large flat saws are in one of each of the three power categories and are shown on the chart below. EPA Tier 3/Interim Tier 4 reduces Nitrogen Oxide and Hydrocarbon (NOx+HC) emissions by 40%. Final Tier 4 regulations take effect in 2012 and 2013, depending on power category, and will reduce Particulate Matter (PM) emissions by over 90%.

35. 35 John Deere Tier 3 Engine Changes The most notable changes to the engines from the previous Tier 2 Engines are the Charge Air Cooling (CAC) which cools the charge air after it leaves the turbo charger but before it enters the engine intake manifold. The CAC is essentially another section on the radiator. Operation of the Flat Saw is not affected by the CAC but it dramatically reduces the Nitrous Oxide Emissions from the diesel exhaust.

36. 36 The other major design change is the Full Authority Electronic Engine Control. Engine performance is governed and monitored by an Electronic Control Unit (ECU). The diesel injector timing and duration is directly controlled electronically. The engine has no throttle cable or linkage. No mechanical governor. Electronic Engine data is collected and processed in the ECU and broadcast onto the Control Area Network Bus. (aka CANBus). John Deere Tier 3 Engine Changes
