Abstract
This article presents a detailed analysis of the potential of dimethyl ether (DME) fuel applications in SI engines. This paper presents the tests results completed on an 1.6-dm3 Opel Astra engine fueled by gaseous fuel as a mixture of LPG and DME. Dimethyl ether is a fuel with properties similar to liquid LPG fuel. In addition, DME is very well miscible with LPG, hence the possibility of creating a mixture with any DME divisions. The assessment of the possibility of using DME as a component of the mixture was carried out with the use of a chassis dynamometer and equipment, enabling an analysis of the changes taking place inside the cylinder. The results of the analyses are the parameters of the thermodynamic processes describing changes in the engine cylinder.

One of the ways to reduce environmental pollution is to use alternative fuels to drive internal combustion engines
The research carried out so far has allowed assessing the possibility of using gaseous fuels to power internal combustion engines
The most common gaseous fuels (LPG and CNG) have a standardized composition, and their use in modern combustion engines with digital control systems for their operation allows for their effective use [1,2,3,4]
Summary
One of the ways to reduce environmental pollution is to use alternative fuels to drive internal combustion engines. DME as a fuel is most often used in Asia (Japan and China and, to a lesser extent, India); the United States of America and the Middle East (Iran) [14,15,16]. India); the United States of America and the Middle East (Iran) [14,15,16] In these parts of the the world, DME is used as a pure energy carrier or as an additive to LPG. The presented two-stage process of obtaining syngas has a significant advantage in the form of the possibility of processing unsorted plastic waste. Metal elements such as aluminum, copper and iron are recovered during the gasification process
