A coating material to be bonded directly to the external surfaces of the engine is described. The basis of the palliative pad is a highly damping material made up of a laminate of heavyweight materials and varied glue lines. The glue lines, of course, must also be impervious to automobile fluids and the temperature cycles which are met on the diesel engine. The procedure involves considerable testing to ascertain the best performance for the least material used, bearing in mind that the maximum thickness allowed is normally only 6mm. When painted, the treatment becomes unobstrusive. The technique of approaching the required reduction in noise level from a diesel engine is one of progressive testing. Ideally, the initial equipment should be bonded to all known suitable parts of the engine and then removed progressively to achieve the shape, form and performance which is required. The parts of the diesel which respond would be the Front Engine Plate, Side Engine Plate, Rocker Box, Block and Sump. Typical treatment is shown.
