Diesel Engine Pulse Turbocharging

By 28 March 2016

High available energy at turbine
Good performance at low speed and load
Good turbocharger acceleration

Poor turbine efficiency with one or two cylinders per turbine entry
Poor turbine efficiency at very high ratings
Complex exhaust manifold with large numbers of cylinders
Possible pressure wave reflection problems (on some engines)

Automotive, truck, marine and industrial engines; two-and fourstroke; low and medium rating (e.g. up to 17-18 bar b.m.e.p. on four-stroke engines)
