Emissions and Fuel Economy of Turbo-Carb, a Retrofit Device

摘要

This report describes EPA's testing of the 'Turbo-Carb' device as part of an evaluation under Section 511 of the Motor Vehicle Information and Cost Savings Act. The evaluation of 'Turbo-Carb' device was conducted at the request of the U.S. Postal Service. The 'Turbo-Carb' device is a one-inch thick carburetor adapter plate which inserts a mesh screen and swirl devices between the carburetor and intake manifold. The device is claimed to improve the preparation of the fuel/air mixture and thereby improve fuel economy and performance. Testing of three typical 1979 model year passenger cars was conducted at EPA's Motor Vehicle Emission Laboratory from March through May 1982. The basic test sequence included the Federal Test Procedure (FTP) and the Highway Fuel Economy Test (HFT). These tests were performed both without and with the Turbo-Carb Device installed. The overall conclusion is that there is no reason to expect that the Turbo-Carbo device will significantly improve fuel economy or performance of a vehicle.
