The current political vision to drastically reduce carbon emissions pushes the electrified powertrain into an increasingly important role in transport sector. However, concerns related battery's effectiveness as energy source need be overcome make this technology widespread. One such concern is safety, catching attention development races towards greater battery density. In way, cathodic chemistry since exothermic reactions are unleashed from components that originally formed active...
An experimental research study was carried out to analyze the influence of different orifice geometries (conical and cylindrical) on injection rate behavior a Common-Rail fuel system. For that purpose, tests in two test rigs were conducted. This nozzles characterized by using non-dimensional parameters cavitation number (K), discharge coefficient (Cd) Reynolds (Re). First, some relevant physical properties injected accurately (density, kinematic viscosity sound speed fluid) specific rig as...
To characterize the macroscopic behavior of Diesel sprays and to validate extend for current high-pressure injection systems correlations existent in literature, it is necessary determine spray geometry accurately, at least terms tip penetration cone angle. These parameters are measured by analyzing images highly sensitive correct edge determination. An algorithm segmentation color based on a likelihood ratio test presented. This compared with others available literature has been validated,...
The two-colour method (2C) is a well-known methodology for the estimation of flame temperature and soot-related KL factor. A 2C imaging system has been built with single charge-coupled device (CCD) camera visualization diesel in single-cylinder 2-stroke engine optical accesses. work presented here focuses on methodological aspects. In that sense, influence calibration uncertainties measured factor analysed. Besides, theoretical study tries to link true soot distributions those derived from...
The objectives of this paper are as follows: (1) To study parametrically OH* and CH* chemiluminescence trace evolution a function the initial pressure, temperature, equivalence ratio premixed flames n-heptane, under autoignition conditions, in constant volume combustion bomb. signals electronically excited states (306 nm) (430 have been detected through band-pass filters with two photomultiplier tubes placed an optical access (2) determine feasibility using active-control parameters for...
The stringent emission regulations have motivated the development of cleaner fuels as diesel surrogates. However, their different physical-chemical properties make study behavior in compression ignition engines essential. In this sense, optical techniques are a very effective tool for determining spray evolution and combustion characteristics occurring chamber. work, quantitative parameters describing diesel-like sprays such liquid length, penetration, delay, lift-off length flame...
E-fuels are a very attractive way for improving the well-to-wheel emissions of CO2 in internal combustion engines. In particular case compression ignition engines, Oxymethylene dimethyl ether (OMEX), an e-fuel with nearly soot-free under mixing-controlled conditions, is good candidate replacement fossil fuels. However, Lower Heating Value OMEX half diesel fuel, which means that much longer injection durations required real engine. addition, low viscosity and lubricity can damage system if...
