The Impact

It is always desirable for a heavy-duty compression-ignition engine, such as a diesel engine, to possess a capability of using alternate liquid fuels without significant hardware modification to the engine baseline. Because fuel properties vary between various types of liquid fuels, it is important to understand the impact and effects of the fuel properties on engine operating and output parameters. This paper intends and attempts to achieve that understanding and to predict the qualitative effects by studying analytically and qualitatively how a heavy-duty compression-ignition engine would respond to the variation of fuel properties. The fuel properties considered in this paper mainly include the fuel density, compressibility, heating value, viscosity, cetane number, and distillation temperature range. The qualitative direct and end effects of the fuel properties on engine bulk fuel injection, in-cylinder combustion, and outputs are analyzed and predicted. Understanding these effects can be useful in analyzing and designing a compression-ignition engine for using alternate liquid fuels.

According to the title, the article compares passenger cars produced in versions with SIE engines (spark ignition engines) and CIE engines (compression ignition engines), taking into account the situation on the Polish automotive market. A group of 25 selected vehicle pairs equipped with the SIE and CIE engine versions has been presented. The measurable comparative criteria have been defined. The results of the comparison were presented in the form of graphs with a commentary. The situation on the Polish automotive market was also assessed in the context of a comparison of both types of vehicles. The final conclusions close the article.
