The automotive sector is currently undergoing drastic changes, driven by the need to simultaneously meet increasingly stringent environmental regulations and achieve more efficient operation over a wide range of engine speeds and loads, while satisfying customer demands in terms of performance, safety, and reliability. In this study an HCCI engine is evaluated for performance and regulated and non-regulated emissions with anhydrous and hydrous ethanol. The Standard EPA Method 8315A was used to determine free carbonyl compounds by derivatization with 2,4-dinitrophenyhydrazine (DNPH). Carbonyls have been measured in emissions using DNPH impregnated cartridges and chemical analyses used high performance liquid chromatography (HPLC). Through the load range achievable, naturally aspirated lean anhydrous ethanol requires high intake temperatures. Although NOx emissions are lower with the use of hydrous ethanol, these emissions are much lower with the use of dry ethanol. The penalty of the use hydrous ethanol is an increase of unburned hydrocarbons and carbon monoxide. Total aldehyde emissions are seen to diminish when an HCCI combustion is carried out with hydrous ethanol. Our analysis gives evidence that HCCI engines can run efficiently on hydrous ethanol fuel and that utilizing hydrous ethanol fuel in HCCI engines improves the energy balance of ethanol production.

Hydrous Ethanol

The growing global demand of energy, the decrease of petroleum reserves and the current of environmental contamination problems, make it imperative to study renewable energy sources for use in internal combustion engines, in order to decrease the dependence on fossil fuels and reduce emissions of pollutant gases. This study aimed to evaluate the emissions of a diesel-cycle engine of an agricultural tractor that uses diesel S500 (B5) mixed with 3, 6, 9, 12 and 15% of hydrous ethanol. It determined emissions of CO2 (ppm), NOx (ppm), and opacity (k value) of gases. A standard procedure was applied considering eight operating modes (M1, M2, M3, M4, M5, M6, M7, and M8) by breaking with an electric dynamometer in a laboratory. The experimental design was completely randomized, with 60 replicates and a 6 x 8 factorial design. Greater opacity and gas emissions were observed when the engine operated with 3% ethanol, while lower emissions occurred with 12 and 15%. With these fuels, the reduction of opacity, CO2, and NOx, in relation to diesel oil, was 24.49 and 26.53%, 4.96 and 5.15%, and 6.59 and 9.70%, respectively. In conclusion, the addition of 12 and 15% ethanol in diesel oil significantly reduces engine emissions.
