In an exclusive interview Doug Mihelick (DM), Commercial Manager of off-road vehicle manufacturer Caterpillar's Mossville Engine Center, discusses Tier 4 Final emission regulation discoverDEF.com (DD).
DD: What effect have the new off-road emissions standards had on fuel consumption?
DM: For products utilizing Selective Catalytic Reduction (SCR), we expect the net fluid consumption of our Tier 4 Final products to improve over our Stage IIIB. Diesel fuel consumption will improve and will be partially off-set by DEF consumption, with a net fluid consumption improvement overall.
DD: What is the Diesel Exhaust Fluid (DEF) dosing rate for the new models?
DM: That varies depending on machine and operator efficiency and we are unable to comment on specific dosing rates.
DD: What additional emissions-related technologies will be used to meet the standards?
DM: We will continue the use of four building blocks - air management, fuel management, electronics and aftertreatment.
DD: When did the first Tier 4 compliant models go on sale?
DM: The first Tier 4 Final machine, a 775G was introduced last Spring at Conexpo. There are other greater than 750 hp Tier 4 Final machines available at this time. Less than 750 hp machines will be introduced in line with our Tier 4 Final launch plans.
