Capstone Turbine Corporation, a leading manufacturer of microturbine energy systems, has released configurations of the C30 (30 kW) liquid fuel microturbine that meet extremely low global emission standards including California Air Resources Board (CARB) requirements for New On-Road Heavy-Duty Engines for Urban Bus - Hybrid service with no aftertreatment.
Test emissions from the C30 Liquid Fuel microturbine measured significantly less than the emissions levels set forth by the CARB standard including NOx at 80% and CO at 99% less than the required levels, Capstone said.
The Capstone C30 Liquid Fuel microturbine is the only engine certified to the CARB emissions levels that went into effect for Model Year 2010 On-Road Heavy-Duty Diesel Engines to operate on diesel fuel with no exhaust aftertreatment, including urea injection or exhaust catalyst.
Emissions were achieved using the next generation of Capstone’s lean premix combustion technology. The result of no after treatment equipment allows Capstone to achieve these emission levels without impact to product efficiency, additional cost or increased vehicle weight.
The Capstone C30 Liquid Fuel microturbine is the only diesel-fueled range extender that has been certified to the CARB Urban Bus and Urban Bus Hybrid standard for operation on diesel fuel, according to the company. Capstone recently completed third party testing and validation of its compressed natural gas (CNG) product and anticipates filing for CARB certification in the coming weeks.
Having the only 2010 CARB-certified range extender for heavy duty transit that does not require exhaust after treatment allows DesignLine to offer a product that meets market requirements and assists transit properties in lowering fleet emissions without incurring the additional cost of changing their existing fueling infrastructure or maintaining costly exhaust after treatment systems.
