Aluminum coated fiber optic sensor for enhancing flow rate measurement
A water flow and velocity aluminum-coated Fiber Bragg Grating sensor system for open channels was designed, simulated and tested. The sensing head was designed, ruggedized and customized to measure velocities at ... -
Aumento de potencia en un motor comercial de encendido provocado alimentado con hidrógeno: mezclas hidrógeno-metano y combustiones anómalas
Este trabajo se ha centrado en el aumento de potencia de un motor comercial de encendido provocado alimentado con hidrógeno. La extremadamente baja densidad del hidrógeno conlleva una menor potencia, frente a otros ... -
Comparative performance of coke oven gas, hydrogen and methane in a spark ignition engine
In this study, coke oven gas (COG), a by-product of coke manufacture with a high volumetric percentage of H2 and CH4, has been identified as auxiliary support and promising energy source in stationary internal combustion ... -
Conversion of a commercial gasoline vehicle to run bi-fuel (hydrogen-gasoline)
Bi-fuel internal combustion engine vehicles allowing the operation with gasoline or diesel and hydrogen have great potential for speeding up the introduction of hydrogen in the transport sector. This would also contribute ... -
Conversion of a commercial spark ignition engine to run on hydrogen: performance comparison using hydrogen and gasoline
The modifications performed to convert the spark ignition gasoline-fueled internal combustion engine of a Volkswagen Polo 1.4 to run with hydrogen are described. The car is representative of small vehicles widely used for ... -
Conversion of a gasoline engine-generator set to a bi-fuel (hydrogen/gasoline) electronic fuel-injected power unit
The modifications performed to convert a gasoline carbureted engine-generator set to a bi-fuel (hydrogen/gasoline) electronic fuel-injected power unit are described. Main changes affected the gasoline and gas injectors, ... -
Design of optical fiber Bragg grating-based sensors for flow measurement in pipes
In this work, optical Fiber Bragg grating (FBG) sensors were used to measure water flow in pipes. Several types of coatings were incorporated into the design of the sensors to examine their effects on the elastic strain ... -
Development of a water flow and velocity optical fiber sensor for field testing
A water flow and velocity fiber optic sensor system was developed and tested. The sensing head was especially developed and ruggedized to measure velocities at different depths, in order to calculate the discharge in channels. -
Experimental study of the performance and emission characteristics of an adapted commercial four-cylinder spark ignition engine running on hydrogen-methane mixtures
The use of hydrogen/methane mixtures with low methane contents as fuels for internal combustion engines (ICEs) may help to speed up the development of the hydrogen energy market and contribute to the decarbonization of the ... -
Gaseous fueling of an adapted commercial automotive spark-ignition engine: simplified thermodynamic modeling and experimental study running on hydrogen, methane, carbon monoxide and their mixtures
In the present work, methane, carbon monoxide, hydrogen and the binary mixtures 20 % CH4–80 % H2, 80 % CH4–20 % H2, 25 % CO–75 % H2 (by volume) were considered as fuels of a naturally aspirated port-fuel injection four-cylinder ...
