EPA Evaluation of the VCD Supplemental Gaseous Fuel Delivery System under Section 511 of the Motor Vehicle Information and Cost Savings Act

摘要

This report announces the conclusions of the Environmental Protection Agency (EPA) evaluation of the 'VCD Supplemental Gaseous Fuel Delivery System' under the provisions of Section 511 of the Motor Vehicle Information and Cost Savings Act. The evaluation of the 'VCD Supplemental Gaseous Fuel Delivery System' was conducted on the application of the manufacturer. The device is designed to operate the engine of a vehicle on a mixture of gasoline and propane. The device consists of a gaseous fuel metering and control unit, a modified carburetor and associated electrical and plumbing components. It functions by replacing some of the gasoline with propane under certain operating conditions. The device causes the engine to idle on propane, cruise on gasoline, and accelerate on a mixture of the two fuels. This is claimed to be more fuel efficient. This combination of improvements in fuel efficency and fuel substitution is claimed to save both fuel and money.
