TLDR
The Wiebe function as discussed by the authors is used to predict the burn fraction and burn rate in internal combustion engines operating with different combustion systems and fuels, including direct injection (DI) and indirect injection (IDI) diesel engines, classical spark ignition (SI) engines, engines with homogeneous charge compression ignition (HCCI) and premixed charge compression ignited (PCCI).Abstract:
Analytical functions approximating the burn rate in internal combustion engines are useful and cost-effective tools for engine cycle simulations. Most functions proposed to date are based on the law of normal distribution of a continuous random variable. The best known of these is the Wiebe function, which is used to predict the burn fraction and burn rate in internal combustion engines operating with different combustion systems and fuels. These include direct injection (DI) and indirect injection (IDI) diesel engines, classical spark ignition (SI) engines and gasoline direct injection (GDI) engines, engines with homogeneous charge compression ignition (HCCI) and premixed charge compression ignition (PCCI). This paper is a tribute to the lasting legacy of the Wiebe function and to the man behind it, Ivan Ivanovitch Wiebe. It includes a historical background to the development of the function in the mid 1950s in the Soviet Union, the controversy that surrounded its introduction, a description of t...read more

Thermodynamic modelling of diesel engine processes for predicting engine performance
TL;DR: In this article, the authors deal with the modelling of diesel engine processes considering heat losses, and variable specific heats using double-Wiebe function for the heat release, and find that early injection timing leads to higher levels of pressure and temperature in the cylinder.
