EPA updates rules to ease commercialization of alternative fuel conversion systems

Green Car Congress

The updated final rule covers alternative fuel conversion of light-duty vehicles and heavy-duty highway vehicles and engines. While properly engineered conversion systems can reduce or at least not increase emissions, poorly designed systems can lead to much more pollution. Exhaust, Evap, and OBD testing. Intermediate age.

California Legislature Considering Bill Requiring Smog Testing for Motorcycles

Green Car Congress

ARB estimates that motorcycles produce up to 15 times the emissions per mile as the average new car or light-duty truck. The original 1975 standards applied to hydrocarbons (HC), one of the two most important contributors to smog, and carbon monoxide (CO), a toxic air pollutant. Background. The original HC standards ranged from 5.0

Achates OPGCI project targeting 50% fuel efficiency gains over downsized GDI engine at reduced cost

Green Car Congress

At idle and low loads, rebreathing of hot exhaust gases provided stable compression ignition with very low engine-out NO x and PM emissions. Rebreathing enabled reduced boost pressure, while greatly increasing exhaust temperature. Hydrocarbon and carbon monoxide emissions after the oxidation catalyst were very low. Earlier post.).
