Engine brake safety and operational considerations

The author was commissioned by the National Transport Commission to investigate the safety and operational considerations pertinent to engine brake use on heavy (motor) vehicles. These vehicles have a Gross Vehicle Mass greater than 4.5t. This assignment is one aspect of the Commission's consideration of engine brake on-road noise performance. This report assesses the safety implications of restricting engine brake in locations where there is a community sensitivity to transport noise. Additionally, information is provided about the operating principles of engine compression brakes and exhaust brakes. This has been done to allow these two common types of engine retardation systems to be differentiated. Both these auxiliary brake systems use the diesel engine to generate retardation and both have an effect on the vehicle's exhaust system. However, the noise performance of engine compression and exhaust brakes is very different.
