Pulse Converters and Summary of Turbocharging Systems

  • N. Watson
  • M. S. Janota


The pulse turbocharging system has been found to be superior to the constant pressure system on the majority of today’s diesel engines. Generally, it is used on all but highly rated engines designed for constant speed and load or marine applications. In chapter 7 it was made clear that the pulse turbocharging system is usually most effective when groups of three cylinders are connected to a turbine or turbine entry. When one or two cylinders are connected to a turbine entry, the average turbine efficiency and expansion ratio tend to fall due to the wide spacing of exhaust pulses. The ‘pulse converter’ has been developed to overcome some of these disadvantages on certain engines (although some versions are suitable for use on any engine) as a compromise between the pulse and constant pressure turbocharging system.
