Capstone Successfully Demonstrates CARB 2010 Diesel Engine Emissions
Capstone Turbine Corporation announced that it has demonstrated with its 30kW microturbine emission levels compliant with the Environmental Protection Agency (EPA) and California Air Resources Board (CARB) 2010 requirements for Heavy Duty Diesel Engine (HDDE). Tests were conducted at Capstone’s development test facilities in Van Nuys, California.
Internal combustion diesel engine manufacturers have been challenged for the last several years to develop technology improvements that reduce emissions to levels specified by the EPA and CARB 2010 standards. Many manufacturers are incorporating exhaust aftertreatment which increases both upfront equipment costs, life cycle costs and may reduce overall engine efficiency.
Capstone microturbines incorporate lean premix combustion technology which offers clean burning exhaust emissions operating on gaseous and liquid fuels. To achieve the emissions improvements, Capstone’s team of engineers developed new fuel injection methods that resulted in significantly lower emissions. Testing demonstrated compliant nitrogen-oxide (NOx) and carbon-monoxide (CO) emissions from part load to full load operation. The proposed EPA and CARB 2010 standards reduce nitrogen-oxide (NOx) emissions over 80% from the current EPA and CARB 2007 standards. The resulting system requires no fuel pretreatment or exhaust aftertreatment to meet these stringent standards.
The new 2010 compliant turbine is the next step in the long-standing Capstone/DesignLine partnership. DesignLine currently employs the CARB 2007 Capstone turbine to produce a hybrid vehicle that lowers emissions, improves fuel economy and reduces noise pollution.
