Ventilation of Motorcoach and Motor-Truck Bodies 320016

This report of the S.A.E Subcommittee on Motorcoach and Motor-Truck Ventilation states that, to the motor-vehicle operator, ventilation means the elimination of gas odors from the coach body or truck cab; but to the public it means, no doubt, simply proper interior ventilation. Adequate interior ventilation becomes a necessity because of the stigma against buses which has arisen due to their characteristic odor. The investigation of the Subcommittee over millions of miles of operation indicates that there is no one cause of fumes, and certainly no single cure.
In the report, discussion is included relating to the causes of gas fumes, such as fumes due to leaks and to engine condition; exhaust-pipe location; carbureter adjustment; the importance of proper driving; engine maintenance and body ventilation. Ten causes of “gassing” are listed.
