Investigation of some of the properties of fossil fuels and biofuels blends to use in SI engines
Journal Title: International Journal of Automotive Engineering and Technologies - Year 2013, Vol 2, Issue 4
Abstract
In this research work, gasoline fuel was considered as the base fuel. Bioethanol, biodiesel and diesel fuel were added to gasoline as additives. The fuel blends were first prepared on different volume basis and then, some important properties of the blends including density, dynamic viscosity, kinematic viscosity and water and sediment were evaluated by following ASTM test methods. The obtained data were analyzed and the results showed that increasing the volume percentage of bioethanol, biodiesel and diesel in fuel blends affect the fuel blends properties, these properties helped to identify the effected blended fuels to utilize at SI engine. At second step, 3 optimized blended fuels were selected based on the fuels properties (E20= 20% ethanol and 80% gasoline- GS1=10% ethanol, 2.5% biodiesel, 2.5% diesel and 85% gasoline- GS2= 18.1% ethanol, 4.31% biodiesel, 4.31% diesel and 73.28% gasoline). These optimized blended fuels were utilized in SI engine and the performance and emission parameters were analyzed.

Structural and contact analysis of disc brake assembly during single stop braking event
An automobile disc brake system is used to perform three basic functions, i.e. to reduce speed of a vehicle, to maintain its speed when travelling downhill and to completely stop the vehicle. During these braking events,...
The electromechanical control of valve timing at different supply voltages
Electromechanical valve systems (EMS) add advantages to engines in terms of performance and emission by eliminating the limitations of conventional variable valve systems that operate mechanically. Electromechanical valv...
