This study investigated the influence on the combustion characteristics and particulate emissions of a diesel engine fueled with DBE (diesel-biodiesel-ethanol) blended fuels. The effects on in-cylinder pressure, heat release rate, combustion duration, diffusion fuel mass, BSPM (brake specific...

An experimental investigation is conducted to evaluate the effects of using diethyl ether and ethanol as additives to biodiesel/diesel blends on the performance, emissions and combustion characteristics of a direct injection diesel engine. The test fuels are denoted as B30 (30% biodiesel and 70%...

This study applies the L9 orthogonal array of the Taguchi method to find out the best hydrogen injection timing, hydrogen-energy-share ratio, and the percentage of exhaust gas circulation (EGR) in a single DI diesel engine. The injection timing is controlled by an electronic control unit (ECU)...

The present work reports studies on the mixing and combustion characteristics of cotton stalk (CS) with 10–100mm in length in a fluidized bed. Effects of length and initial weight percentage of CS, diameter of alumina bed material as well as gas velocity on the mixing characteristics of CS...

In this study, effects of DME (dimethyl ether) pre-mixing ratio and cooled external EGR (exhaust gas recirculation) rate on combustion, performance and emission characteristics of a DME-diesel dual fuel PCCI (premixed charge compression ignition) engine were investigated in a 2105 engine. PCCI...

The present work explores the possibility of simultaneous reduction of NOx and smoke of a stationary CI (compression ignition) engine fuelled with biodiesel blend. Fuel injection timing is retarded which resulted in lower NOx emission with an increased smoke intensity. NOx emission of the...

The world is presently confronted with the twin crisis of fossil fuel depletion and environmental degradation. Indiscriminate extraction and lavish consumption of fossil fuels have led to reduction in underground based carbon resources. The search for an alternative fuel, which promises a...

The rapid depletion of fossil fuels and environmental concerns make alternative fuels such as biodiesel more attractive. Biodiesel has properties comparable to ultra low sulfur diesel (ULSD), however certain properties of biodiesel such as viscosity, calorific value, density and volatility...

Biodiesel has been a lucrative commodity in the current global economic trade as there is mounting concern for issues relating to the environment and oil depletion. Biodiesel has been proven to be the next alternative renewable fuel as it is environmentally friendly, sustainable and possesses...

The performance of two synthetic aviation fuels was evaluated in a meso-scale heat recirculating combustor and the respective results compared with the combustion characteristics of a conventional petroleum-based jet fuel. One of the alternative jet fuels was synthesized via a Fischer–Tropsch...
