The Method for Development of a Diesel Engine Universal Performance Map

Multi-parameter characteristics (performance maps) of the diesel engines of large, medium, and small power have been investigated. The operation regimes with nominal (rated) brake specific fuel consumption (BSFC) and estimated characteristics of the engines' fuel economy have been determined.

The method for plotting normalized multi-parameter engine characteristics within dimensionless coordinates has been developed along with the the method for generalization of normalized multi-parameter characteristics of the engines with different rated power.

Also, the universal performance map suitable for a diesel engine of arbitrary power has been obtained.
