Fuel Efficient Exhaust Systems 810858

A potential for saving fuel by reducing the exhaust system backpressure of diesel engines has been shown. This paper will quantify the relationship between backpressure and fuel consumption over a range of backpressures, horsepowers and rpm's. The cost benefit of low backpressure exhaust systems for medium-and heavy-duty trucks will be discussed and guidelines for designing these systems will be presented.
