Ricardo, a U.K. company known for various vehicle drivetrain technologies,
yesterday it was working on advanced research into
technology capable of achieving U.S. Super Ultra-Low Emission (SULEV) and Tier II Bin
requirements. The global manufacturer that Ricardo is working with went unnamed. Ricardo says it wants to "remove the diesel combustion engine from the environmental debate on regulated emissions -- allowing advanced diesel engines to take their place alongside gasoline
powered vehicles in the future of environmentally friendly automotive products". Since Tier II Bin 2 requires emissions roughly a sixth those of the already stringent Euro 5, getting these diesel engines on the road will make quite a difference to the environment. Ricardo says it is using "advanced air handling systems, two-stage boosting, advanced exhaust gas recirculation and application of closed-loop cylinder pressure-based engine controls" to reduce emissions.
