EPA updates rules to ease commercialization of alternative fuel conversion systems

Green Car Congress

While properly engineered conversion systems can reduce or at least not increase emissions, poorly designed systems can lead to much more pollution. The revised procedures will vary based on the age of the vehicle or engine being converted. Exhaust, Evap, and OBD testing. MY >= current calendar year - 1. Intermediate age.

EPA Proposes to Streamline Approval Process for Fuel Conversion Systems

Green Car Congress

The new options would reduce some economic and procedural impediments to clean alternative fuel conversions while maintaining environmental safeguards to ensure that acceptable emission levels from converted vehicles are sustained. EPA expects the streamlined approach to result in a cost savings for many converters. Intermediate age.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

Jacobson used a computer model of global climate, air pollution and weather that he developed over the last 20 years and updated to include additional atmospheric processes to analyze how soot can heat clouds, snow and ice. Particle traps filter out soot particles from exhaust fumes. Mark Jacobson. Dessler et al., Guenther et al.,

GM Developing New Concept for Emission Control for Lean-burn SIDI Engines: Passive Ammonia SCR

Green Car Congress

However, SIDI engines also have the potential for increased pollutant formation, and require either careful control of combustion for reduced engine-out emissions, or an exhaust after-treatment systems similar to those under development for diesel vehicles. Lean-burn (i.e., a high air-to-fuel ratio) SIDI (e.g.,

California Legislature Considering Bill Requiring Smog Testing for Motorcycles

Green Car Congress

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. Tampering, according to ARB, would include removal of the catalytic converter or carbon canister, changing adjustable parameters or adding devices to boost horsepower.
