Capstone Turbine C30 CNG microturbine certified to 2010 emissions requirements for on-road heavy duty diesel engines for urban buses
Capstone Turbine Corporation has released configurations of the C30 compressed natural gas (CNG) microturbine that meet or exceed emissions standards, including the US Environmental Protection Agency and California Air Resources Board (CARB) 2010 requirements for On-Road Heavy Duty Diesel Engines (HDDE) for Urban Bus.
The C30 CNG microturbine is Capstone’s second engine CARB-certified for automotive applications; the C30 liquid fuel microturbine range extender was certified in June 2010. (Earlier post.) Capstone also has versions of its C30, C65 and C200 products certified to CARB stationary emission standards.
Test emissions from the C30 CNG microturbine measure significantly less than the emissions levels required by CARB and the EPA for 2010 and Subsequent Model Heavy Duty Urban Bus Engines.

The C30 CNG microturbine doesn’t require fuel pretreatment or exhaust aftertreatment to meet these standards, thereby avoiding additional costs, decreased product efficiency and increased vehicle weight.
The C30 CNG microturbine is used in Hybrid Electric Vehicles (HEV) as a range extender for truck and fleet applications such as urban buses, passenger vehicles, trolleys, class 8 heavy-duty tractors and heavy duty trucks. It delivers benefits unattainable with conventional engines for cleaner, more reliable and quieter mass transportation.
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 and controls methods that resulted in significantly lower emissions.
