A bypass system for a diesel engine having a turbocharger, a bypass conduit, a valve and a controller which cooperate to bypass a portion of the combustion air compressed by the turbocharger bypassed to a turbine portion of the turbocharger or to the atmosphere, a controller containing maps based on empirical fixed point data specific to the engine, turbocharger and bypass system responds to signals indicative of changes in atmospheric pressure, inlet manifold pressure and engine speed to control the valve and prevent the turbocharger from surging.
[ What is claimed is:] [1.] A method of preventing surging in a turbocharger utilized in a diesel engine, the turbocharger having a compressor portion in fluid communication with an inlet manifold for supplying combustion air to the engine, a turbine portion in fluid communication with an exhaust manifold for directing exhaust gases from the engine to the turbine portion of the turbocharger, a bypass valve in fluid communication with the compressor and turbine portions and a controller which operates the bypass valve based on empirical fixed data points ...
