New Leiderman–Khlystov Coefcients for Estimating Engine Full Load Characteristics and Performance

Dariusz Szpica

Abstract

The paper presents a method of calculating the full load engine characteristics based on the Leiderman–Khlystov relation. Because the values of the coefcients of the discussed function available in literature were determined for obsolete engine designs, an attempt was made to update them. To this end, a chassis dynamometer was used where a database of results had been built for a variety of vehicles. Following the data collection, the coefcients for variety of fueling system (six groups: fuel injected gasoline and turbocharged gasoline, spark ignition LPG I–II and IV generation, naturally aspirated diesel and turbocharged diesel) were determined. The identifcation of the coefcients was carried out in Matlab-Simulink indicating the applicability of the said function for most of the engines, yet the recent popularity of turbocharged gasoline engines requires an additional analysis of the possibility of use of a diferent functional description. The full load engine characteristics is a basis for the vehicle performance characteristics and, further, for modeling of trafc in a variety of aspects of the vehicle operation.
