Impact of engine pressure-temperature trajectory on autoignition for varying fuel properties

Experimental Study of Autoignition and Combustion Gas-air Mixtures in Dual Fuel Engine

The paper shows a test results of single cylinder, direct injected, self ignited dual fuel engine. One has analysed a combustion parameters calculated on base of recorded indicator diagrams. The comparison included: the ignition delay period, the cylinder pressure, the rate of pressure rise, the average medium temperature, the heat release rate, the total combustion time and the indicated effic...

Characteristics of fish oil biodiesel with the impact of diesel fuel addition on a CI engine

The present study focuses on the optimization in the use of non-petroleum fuel derived from waste fish oil fuels, as a replacement for petroleum diesel fuel for compression ignition engine. The study comprises of comparison between results of fish oil biodiesel-diesel blends on a compression ignition engine. Fuel properties such as viscosity, density, heat value of fuel, cetane number and a fla...

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

Effect of Material Gradient on Stresses of Thick FGM Spherical Pressure Vessels with Exponentially-Varying Properties

Using the Frobenius series method (FSM), an analytical solution is developed to obtain mechanical stresses of thick spherical pressure vessels made of functionally graded materials (FGMs). The cylinder pressure vessel is subjected to uniform internal pressure. The modulus of elasticity is graded along the radial direction according to power functions of the radial direction. It is assumed that ...

Trajectory engine: a backend for trajectory sampling

The management of communication networks increasingly requires detailed knowledge of network usage, acquired by direct measurement. We report on the design and implementation of a backend system for Trajectory Sampling, a method for consistent sampling of packets across a network domain. This Trajectory Engine collects trajectory samples and stores them after appropriate preprocessing. It provi...
