Abstract

The conversion of the diesel engine to exclusive use of vaporized alcohol is proposed. Two stages in the testing of the engine are envisaged aiming for a conclusive economic-operational comparison, within two geometries: in the first, with the engine in its original configuration; in the second with the engine adapted for the use of alcohol adiabatically in the air of the turbo-compressor output. In each set of tests the output power as a function of the fuel-air and of the rotation are measured. The emission of pollutants, handling and other necessary properties will be monitored. The power is controlled by the fuel discharge with the admission of air from the turbocompressor, preferably, open. The Diesel engine used is model MWM4. 1 OTCA with air intake cooler, as used in trucks, harvesters and buses. Some electronic controls are designed locally. It is proposed to develop the engine to a level for swift application in the market, providing conditions for the drastic reduction in the emission of pollutants into the urban atmosphere. (AU)
