Environment Canada study finds vehicle exhaust a significant source of isocyanic acid; suggests consideration of new emission standard

Green Car Congress

Researchers at Environment Canada have found that vehicle exhaust is a significant source of isocyanic acid (HNCO), a toxic gaseous acid that is a product of various forms of combustion and a potential health concern. Automobile exhaust is also a known source of inorganic acids such as nitric (HNO 3 ) and nitrous (HONO) acids.

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. EPA evaluated the requirement and determined that it is appropriate to introduce new flexibilities for all clean alternative fuel converters and to expand the compliance options for certain categories of conversions.

2015 VW Jetta TDI: a more refined, powerful and efficient diesel within a nicely redesigned model line

Green Car Congress

The aluminum-alloy cross-flow cylinder head has a novel placement of intake and exhaust valves; the intake and exhaust ports for each cylinder are positioned one behind the other in the direction of flow. In other words, there is not a separate intake or exhaust camshaft. Top: Valve layout. We can now adjust about 50 ?

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.
