PAGE EIGHT MechEitg Prof Causes of Air By KAY MILLS While black diesel engine smoke and Us powerful fumes may be a nuisance, they may contribute less to air pollu tion than the exhaust from vehicles using gasoline engines, Wolfgang E. Meyer, professor of mechanical engineering, said re cently. ‘‘The diesel engine is not a big offender because? it does not seem to gave off as many elements which cause air pollution as does the gasoline engine,” Meyer said. The escape of diesel engine gases into the atmosphere, known as "blowby," is being studied here as one aspect of the complex and serious prob lem of air pollution, he said. Meyer added that exhaust and fumes of the gasoline engine have already been studied and that he lias been given a 315.439 grant by Die U S. Public Health Service to analyze diesel blowby. “Even though diesels are noisier and heavier than gasoline engines. Iliey are used in trucks, buses and now some taxis and small deliv ery (rucks because they consume less fuel,” Meyer said. Three components of exhaust and fumes contribute to air pol lution, Meyer said. One com ponent, ruch as carbon mon oxide and oxides of nitrogen is dangerous in itself, he said. An other, unburned particles in ex haust, reacts with elements of the environment and then be comes harmful, he added. “Jn California.” Meyer said, “un humed hydro-carbons from ex haust react under the warm sun vilh elements in the atmosphere lo form smog. This smog can irri tate Die eyas and is dangerous to plants. Its effects on respiratory systems are not yet fully under stood.” Los Angles suffers more from smog th;in other areas because of its climate and location in a ‘‘bowl.” Meyer said. The area’s bich temperature speeds reactions between Iho undesirable parts ef exhaust and elements in the at mosphere. he said, adding that little wind circulates in the bowl 1o clear the smog. “Effects of air pollution in the East come more directly from the exhaust components than their re action with the atmosphere,” Mey er said. Discussing the third element in air pollution, Meyer said, “Some partially burned hydro-carbons may also be harmful to the eyes. Others have caused cancer in rats Hat Society Program Scrolls, senior women’s hat so ciety, will sponsor a program to introduce students, especially sen ior women, to the University Placement Service at 8 tonight in 111 Boueke. Discusses Pollution in laboratory experiments. Yet how long can these particles be dangerous in the open atmos phere? The amount of harmful fumes coming directly from an exhaust pipe naturally contrasts greatly with those in open air.” Attempts io eliminate these unburned or partially burned ! particles from exhaust have led to development of an after burner to complete their re action, Meyer said. “A recirculation device in gaso line engines can also cut down the escape of some harmful fumes. The gases are not allowed to es cape from the engine but are piped back through the system un til they ate completely burned.” Use of afterburners is a costly process, Meyer said; Iheir initial cost is front $l5O to $2OO. "If required by law in order i lo cut down pollution, after burners might raise the cost of automobiles so much that use of diesel engines might spread. Before this happens, we must know how much diesels con tribute lo air pollution." In studying the components of diesel blowby and how they may contribute to air pollution, Meyer will measure the amounts of var ious gases from a representative truck diesel engine and will de termine their noxiousness. The investigations v.ill not only! concern engines in optimum con ditions, he said, but they will also: deal with the effects of wear, poor; maintenance and improper adjust-! ment on blowby. 1 _ /• j \ / I'S *Toreyton's Dual Filter in duas partes divisa est!" says Lucius (Dead-eye) Claudius, crack marksman of the XVI Cohort catapult team. “People come from Nero and far for Tareyton,” says Dead-eye. “Vero, Tareyton’s one filter cigarette that really delivers de gustibus.
