Abstract The engine manufacturer and limits the greenhouse effect and improved thermal efficiency of an engine must go to considerable emissions of carbon dioxide and internal combustion engines will be relevant in the future. Homogeneous charge compression ignition (HCCI) technology to reduce exhaust emissions and fuel consumption of a high-efficiency alternative to combustion engines. However, still the HCCI engine combustion phasing control, easy operation difficult challenges, the operating range and the unburned hydrocarbons and CO emissions extend high. HCCI and alternative fuel ethanol functioning as an internal combustion engine with an eye toward maintaining stability is a way to explore new frontiers. This study was designed to increase knowledge database HCCI ethanol fuel. Introduction Sustainable globalization and increased mobility of supply and consumption, engine fuel engine increases the concentration of toxic components of the exhaust gas is increased demand for emission reductions. For the last concept engine, homogeneous charge compression ignition at reducing consumption and compression ignition best ignition engines that combine the characteristics of a promising idea to provide superior performance, fuel economy and emissions. By compression ignition of fuel due to the increased pressure and temperature history is made. Ignition of the combustion chamber with no external ignition occurs simultaneously in several places. The homogeneous
