TL;DR: In this paper, the effect of the start of fuel injection timing (SOI) on the combustion characteristics, performance and emissions of a direct-injection spark-ignition engine fueled with a 20% methane augmented hydrogen rich syngas of molar ratio of 50% H2 and 50% CO composition was investigated.

TL;DR: In this paper, a single-cylinder Direct-Injection Stratified-charge (DISC) engine incorporating a combustion process similar to the Texaco Controlled Combustion System (TCCS) was tested with a spark-ignited direct-injection engine burning gasoline where the piston temperature was varied by controlling cooling water and oil temperature.
Abstract: Light-load unburned hydrocarbon emissions were studied experimentally in a spark-ignited direct-injection engine burning gasoline where the piston temperature was varied The test engine was a single-cylinder Direct-Injection Stratified-Charge (DISC) engine incorporating a combustion process similar to the Texaco Controlled Combustion System At a single low load operating condition, the piston temperature was varied by 50 K by controlling the cooling water and oil temperature The effect of this change on unburned hydrocarbon emissions and heat release profiles was studied It was found that by carefully controlling the intake air temperature and pressure to maintain constant in- cylinder conditions at the time of injection, the change in piston temperature did not have a significant effect on the unburned hydrocarbon emissions from the engine It was concluded that fuel wetting of the piston surface is not a significant source of hydrocarbon emissions from engines of this type when burning gasoline (A) For the covering abstract of the conference see IRRD 852385

TL;DR: In this article, the effect of ethanol-gasoline blends on fuel properties characteristics of variable speed spark ignition (SI) engines using standard laboratory methods was investigated for density, API gravity, kinematic viscosity, cloud point, flash and fire point, heat value, distillation and octane number.
Abstract: This paper investigates the effect of ethanol-gasoline blends on fuel properties characteristics of variable speed spark ignition (SI) engines using standard laboratory methods. Fuel properties tests were conducted for density, API gravity, kinematic viscosity, cloud point, flash and fire point, heat value, distillation and Octane number using ethanol-gasoline blends with different percentages of ethanol. The blends selection was based on successful completion of engine standard short test carried out on a computerized four cylinders, four stroke, and variable speed SI engine with eddy current dynamometer and data logging facilities. Fuel properties test results showed that blends densities and kinematics viscosity increased continuously and linearly with increasing percentage of ethanol, while API gravity and heat value decreased with decreasing percentage of ethanol. Furthermore, cloud point, flash and fire points for blends were found to be higher than pure gasoline fuel, while distillation curves were lower. The tested blends Octane rating based on Research Octane Number (RON) increased continuously and linearly with increasing percentage of ethanol. Results from this study will be valuable on the assessment of the suitability of ethanol-gasoline blends as bio-fuel for automotive industry to cater for the country needs.

TL;DR: In this article, a reformer is delivered by a fuel pump to a reformers at relatively high pressure, where it is heated by exhaust gases from a spark ignition engine and decomposed over a catalyst bed to form carbon dioxide and hydrogen, this being a constant pressure process.
Abstract: Methanol is delivered by a fuel pump to a reformer at a relatively high pressure, where it is heated by exhaust gases from a spark ignition engine and decomposed over a catalyst bed to form carbon dioxide and hydrogen, this being a constant pressure process. The mixture is fed to an auxiliary turbine which helps drive the output shaft of the spark ignition engine. The low pressure exhaust gases from the auxiliary turbine are mixed with air and fed to a spark ignition engine where they are combusted.
