SAFETY ENVIRONMENTAL vice life of the catalyst requiring it to be replaced a costly repair to the exhaust system All machines using the CEGR DOC DPF technologies will require the use of American Petroleum Institute API rated CJ 4 sometimes referred to as low ash oil to help reduce the amount of particulate matter in the DPF While not specific to Tier 4i compliant diesel engines this high performance engine oil has superior soot viscosity control reduced low temperature sludge buildup and reduced high temperature deposits and helps maintain viscosity in severe temperature service Mechanic training Reducing emissions down to near zero levels introduces a number of changes in engine and equipment design and each manufacturer has determined its own product compliance strategy These changes could include devices such as particulate filters oxidation catalysts lean NOx traps or SCR that are integrated into the existing exhaust and muffler systems Technicians need to have a general familiarity with electronically controlled engines exhaust aftertreatment control devices the concept and practice of measuring backpressure along with general exhaust equipment maintenance There is no federal requirement to upgrade any existing engine to the new Tier 4 standards and operation New operator warning lights and dashboard indicators have been introduced by some manufacturers to denote levels conditions of new diesel exhaust fluid or the indication of an active particulate filter regeneration event that might require special attention Some Tier 4 engines may use particulate filter technology that could require periodic maintenance and cleaning and or removal This may also involve some new equipment in a service facility such as an oven or cleaning cabinet to fully service the filters Some of these functions can be performed by vendors off site For manufacturers that use SCR technology service employees will need to be trained in the general aspects of SCR technology including the basic SCR components on the machine SCR catalyst storage tank spray nozzle and plumbing systems fluid flows and pressures and troubleshooting Training on the safe handling storage disposal and dispensing of diesel exhaust fluid including its material safety data sheet MSDS is also strongly suggested P Q Information for this article courtesy of Case Caterpillar Cummins Doosan and the Diesel Technology Forum ƉĞĐŝĂůŝnjĞĚ ƚĞĞů ŽůƵƟŽŶƐ For nearly 50 years Astralloy Steel Products has been ƉƌŽǀŝĚŝŶŐ ŝŶŶŽǀĂƟǀĞ ĂŶĚ ĐŽƐƚ ĞīĞĐƟǀĞ ƐŽůƵƟŽŶƐ tĞ have an extensive product line of abrasion resistant and specialty steel plate and bar Q Astralloy V Plate Bar Q Astralloy 8000 Q EB 450 Q Astralloy 4800 Q ƐƚƌĂtĞĂƌ ϱϱϬ Q ƐƚƌĂtĞĂƌ ϱϬϬ Q ƐƚƌĂtĞĂƌ ϰϱϬ Q ƐƚƌĂtĞĂƌ ϰϬϬ Q A 514 Q ƐƚƌĂůůŽLJ dƌŝƉ dƵī Q Rol Man Q 4330 V Mod Bar Q 4145 H Mod Bar Q Armor V2 Q BP6 33 ƚ ƐƚƌĂůůŽLJ ǁĞ ŽīĞƌ ƌĞĂĚŝůLJ ĂǀĂŝůĂďůĞ ŝŶǀĞŶƚŽƌLJ ĂŶĚ ĨĂďƌŝĐĂƟŽŶ Θ ŵĂĐŚŝŶŝŶŐ ƐĞƌǀŝĐĞƐ KƵƌ ĐůŝĞŶƚƐ ĂůƐŽ ďĞŶĞĮƚ ĨƌŽŵ our unparalleled experience with ƚŚŽƵƐĂŶĚƐ ŽĨ ĂƉƉůŝĐĂƟŽŶƐ ĂĐƌŽƐƐ ǀĂƌŝŽƵƐ ŵĂƌŬĞƚƐ ĂŶĚ ŝŶĚƵƐƚƌŝĞƐ www astralloy com h dŽůů ĨƌĞĞ ϭ ဒϬϬ ϲϯϯ ϲϲϯϱ ĂŶĂĚĂ ϳဒϬ ϰϰϬ ဓϯϭϭ ƐƚƌĂůůŽLJ ƚĞĞů WƌŽĚƵĐƚƐ ŝƐ Ă ǁŚŽůůLJ ŽǁŶĞĚ ƐƵďƐŝĚŝĂƌLJ ŽĨ EƵĐŽƌ ŽƌƉŽƌĂƟŽŶ ƚŚĞ ůĂƌŐĞƐƚ ƉƌŽĚƵĐĞƌ ŽĨ ƐƚĞĞů ŝŶ ƚŚĞ hŶŝƚĞĚ ƚĂƚĞƐ 16 PIT QUARRY May 2013 www pitandquarry com
