The options for the regeneration of a Diesel Particulate Filter (DPF) using hydrogen rich gas are investigated. The advantages of using hydrogen rich gas for this purpose are described. The system requirements for such a system are also evaluated. The use of a plasmatron fuel converter for the onboard generation of hydrogen rich gas from diesel fuel is discussed. The advantages of homogeneous, ...

Biodiesel is one of the promising renewable, alternative and environmentally friendly biofuels that can be used in diesel engine with little or no modification in the engine. In the present study an experimental investigation has been carried out on the combustion and performance characteristics of a CI engine running with biodiesel under steady state operating conditions. The experimental work...

Abstract The present research activity's major objective is to improve the performance and emission characteristics of diesel engines that burn pyro oil cashew nut shell nanoparticles. This work identifies nanoparticles should be added allow it utilized efficiently in compression ignition engines. In this experiment, two nanoparticles, Al 2 O 3 TiO , were mixed with oil. For testing purposes, c...

at the present work, the effect of cold exhaust gas recirculation (egr) on combustion and pollution of a dual fuel engine has been investigated by cfd code fire. the turbulent flow within the combustion chamber is simulated using the k-ε turbulence model, which is modified for engine flows. “wave” and “eddy break up” models are employed to predict combustion and spray process. the calculations ...

Fire experiments were conducted in the Safety Research Coal Mine (SRCM) at the National Institute for Occupational Safety and Health, Pittsburgh Research Laboratory, with coal, diesel-fuel, electricalcable, conveyor-belt, and metal-cutting fire sources to determine the response of fire sensors to productsof-combustion (POC). Metal oxide semiconductor (MOS) and smoke fire sensors demonstrated an...

In the last 30 years, diesel engines have made rapid progress to increased efficiency, environmental protection and comfort for both light- and heavy-duty applications. The technical developments include all issues from fuel to combustion process to exhaust gas aftertreatment. This paper provides a comprehensive summary of the available literature regarding technical developments and their impa...

We report for the first time on the use of water-continuous emulsions stabilized by a bio-based macromolecule in a compression-ignition diesel engine and compare their performance, combustion and emissions against the base fuels (diesel, biodiesel, and jet fuel). For this purpose, high internal phase ratio emulsions (70:30 fuel-to-water) were produced by mechanical emulsification using carboxym...

Vegetable oils and their derivatives (especially methyl esters), commonly referred to as “biodiesel,” are prominent candidates as alternative diesel fuels. They have advanced from being purely experimental fuels to initial stages of commercialization. They are technically competitive with or offer technical advantages compared to conventional diesel fuel. Besides being a renewable and domestic ...
