Gasoline–water mixed injections are of great interest because their advantages for reduced manufacturing costs and improved atomization, with the potential to alleviate engine detonation reduce emissions. In this work, based on principle impinging flow, a real-time gasoline–water mixture preparation system internal combustion engines was designed performance compared standard swirl mixing techn...

Experiments to identify the knock trends of lean gasoline-air mixtures, and such mixtures enhanced with hydrogen (H2) and carbon monoxide (CO), were performed on a single-cylinder research engine with boosting capability. The experimental method used to investigate knock trends consisted of determining the octane number (ON) of the primary reference fuel (mixture of isooctane and n-heptane) sup...

This study investigates the effects of ethanol-blended gasoline with oxygenated additives on a multi – cylinder Spark Ignition (SI) Engine. The experiments were conducted in two stages. In stage I, the test fuels were prepared using 99.9% pure ethanol and gasoline with a cycloheptanol blend, in the ratio of E69.5 + 0.5 cycloheptanol, E64.6 + 0.4 cycloheptanol, E59.7 + 0.3 cycloheptanol, E49.8 +...

Homogenous charge compression ignition (HCCI) combustion is spontaneous multi-site combustion of a nominally premixed air/fuel mixture that exhibits high rate of pressure rise and short combustion duration. To avoid excessive pressure rise rate and knocking, HCCI engines are fueled with highly diluted mixture using a combination of excess air and/or EGR. HCCI combustion is attractive due to ...

One of the problems that occur in our earth is air pollution and depletion fossil fuel stocks. Researchers want to make research on how burns completely, so resulting exhaust gas environmentally friendly. In addition, this expected as an education comparison before after turbofan given. This study will control AFR (Air Fuel Ratio) intake get right ratio stoichiometry. By controlling into engine...

Work undertaken by Lotus Engineering and partners has shown that the miscibility of the low-carbon-number alcohols with gasoline provides a powerful tool to enable the introduction of methanol as a transport fuel in a wholly evolutionary manner. This is primarily facilitated by the fact that the CAFÉ regulations in the US (together with other incentives in other countries, such as Sweden) have ...
