Long Beach Transit (LBT), a Californian transportation agency focused on the use of clean air technology, has been granted $600,000 grant from the Mobile Source Air Pollution Reduction Review Committee (MSRC) of the South Coast Air Quality Management District Near Zero Incentive Program for the purchase of 40 “near zero” compressed natural gas (CNG) engines.
The engines are upgrades to a recent bus procurement as the “near zero” engines were not available when the purchase was authorized in 2016. The buses will be equipped with the Cummins Westport 8.9 liter engine that is certified by the California Air Resources Board and the U.S. Environmental Protection Agency to meet or exceed optional and more stringent near zero standards.
LBT purchased its first CNG buses in 2012. It serves 26 million annual boarding customers in Long Beach, Lakewood, Signal Hill and portions of adjoining areas.
Cummins Westport 8.9 liter engine
The Cummins-Westport 8.9 liter ISL G Near Zero NOx engine offers quieter and cleaner performance with power that’s comparable to a conventional diesel. Rated at 320 horsepower and 1,000 lb.-ft. of torque, the engine delivers emissions that are 90 percent lower than the current EPA and California Air Resources Board (CARB) NOx limit of 0.2 g/bhp-hr, and also meet the 2017 EPA greenhouse gas (GHG) emissions requirements.
Like the industry leading ISL G engine, the ISL G Near Zero operates on 100% natural gas which can be carried on the vehicle in either compressed (CNG) or liquefied (LNG) form. The ISL G Near Zero can also run on renewable natural gas (RNG).
