Engine Operating Conditions and Fuel Properties on Pre-Spark Heat Release and SPI Promotion in SI Engines

Performance Characteristics of Spark Ignition Engine Using Ethanol as Fuel at Different Operating Conditions

The present study converses the usability of ethanol as a clean and green renewable alternative fuel for spark ignition engine. The study emphasizes not only on the inherent properties of ethanol as a fuel but also elaborately reviews about the performance characteristics of the engine considering the effects of different important parameters like cyclic variability, ignition timing, internal c...

An Experimental Investigation of Spark Ignition Engine Fueled with Ethanol/Iso-octane and Methanol/Iso-octane Fuel Blends

Alcohols have been used as a fuel for engines since 19th century. Among the various alcohols, ethanol and methanol are known as the most suited renewable, bio-based and ecofriendly fuel for spark-ignition (SI) engines. The most attractive properties of ethanol and methanol as an SI engine fuel are that it can be produced from renewable energy sources such as sugar, cane, cassava, many types ...

Impact of Methanol–Gasoline Fuel Blends on the Performance and Exhaust Emissions of a SI Engine

An Experimental Investigation of Spark Plug Temperature in Bi-fuel Engine and Its Effect on Electrode Erosion

Temperature is one of the effective parameters in erosion of spark plug electrodes. In this research, temperature of spark plug was measured in engine's different operation conditions with two types of fuels: compressed natural gas and gasoline. Test results showed that, temperature of center electrode is lower than ground electrode and maximum difference between them is 110ºC that occurs at...

Combined effect of ignition and injection timing along with hydrogen enrichment to natural gas in a direct injection engine on performance and exhaust emission

To improve the engine performance and reduce emissions, factors such as changing ignition and injection timing along with converting of port injection system to direct injection in SI(spark-ignited) engines and hydrogen enrichment to CNG fuel at WOT conditions have a great importance. In this work, which was investigated experimentally (for CNG engine) and theoretically (for combustion Eddy Bre...
