Influence of the Use of EtG Synthetic Fuel in Spark-Ignition Engines on Vehicle Fuel Consumption and Pollutant Emissions

Abstract

This article presents the properties of EtG synthetic fuel (Ethanol to Gasoline) as a substitute for fuels in an installation using ethanol from food waste as a raw material. The results of this research on the process of supplying the engine with EtG fuel are presented, in which the operational suitability of this fuel was verified, including environmental requirements. The results of pollutant emission tests from vehicles with spark-ignition engines in dynamic driving conditions in the New European Driving Cycle (NEDC) type approval tests and the World Harmonized Test Cycle (WLTC) test, both on a “cold” and “hot engine”, are presented. It was found that EtG fuel is characterized by lower emissions of carbon monoxide, nitrogen oxides, and methane, and higher emissions of non-methane hydrocarbons compared to E10 commercial gasoline, while the specific distance emission of carbon dioxide for both fuels was very similar.
