Measuring fuel consumption of combustion engines on chassis, engine or powertrain test stands

Measuring fuel consumption

Measuring fuel consumption

The measurement of fuel consumption is necessary for testing and validation of combustion engines during research and development. Using a fuel flow measurement system allows developers to optimize the engine’s fuel consumption in dynamic as well as stationary load points, which is necessary for best fuel consumption results in test cycles, such as NEDC (New European Driving Cycle) and WLTP (Worldwide Harmonized Light vehicles Test Procedure). The majority of fuel consumption tests is carried out on engine test stands but the measurement results can also be validated with another testing cycle on a powertrain test stand or chassis dynamometer.

RDE Testing for Non-Road Mobile Machinery
RDE Testing for NRMM
After the introduction of Real Driving Emission (RDE) tests for light- and heavy-duty vehicles, focus is now also shifting to the area of non-road mobile machinery (NRMM).
Brake Dust Measurement
Brake Dust Measurement
A series of legislative measures has significantly reduced the amount of emissions that is being emitted by internal combustion engines of light and medium-duty vehicles.
Real driving emissions with RDE CoDriver

Real Driving Emission (RDE) tests confirm the results produced during an emissions test on a chassis dynamometer to ensure that vehicles meet the set limits in the real world.
Microscopic Measurement of Diffusion
Spectra taken at different depths within the polymer layer with normalized spectra.
In order to engineer materials with controlled diffusive properties, we need to be able to measure the diffusive process in situ. Ideally, we would like a technique that provides molecular information with resolution on a microscopic scale, that is non destructive of the samples, and can be set up and used on a laboratory bench top with a minimum of time and effort involved in sample preparation. Raman microprobe spectroscopy is an ideal candidate for this type of studies. Use of visible light combined with a confocal microscope provides a probe with spatial resolution of a micron or better, and coupling of such a microscope to a modern Raman spectrometer equipped with holographic notch filters and CCD multi channel detectors allows rapid acquisition of Raman spectra which can be correlated with the chemical state of the species and its physical environment.
Features and Benefits of Pulsed RF GD OES for the Characterisation of Electrodes of Li-ion Batteries.
A Li-ion battery.
A Li-ion battery is a rechargeable battery in which lithium ions move between the anode and the cathode creating an electricity flow. Whether you study new electrodes or coatings behaviors, charge and discharge processes, process controls, or perform comparative studies for Li-ion batteries, Pulsed RF Glow Discharge Optical Emission Spectrometry is a valuable companion tool.
Raman Spectroscopy Applied to the Lithium-ion Battery Analysis

The application note explains how the Raman Spectroscopy can be helpful in the analysis of cathodes and anodes in Li-ion batteries. Today’s state of art of technology requires more reliable, more efficient and powerful energy sources. Lithium-ion batteries are thus of high interest. Raman spectroscopy adapts to the different stages of life of these batteries, such as the characterization of new materials for more flexible systems, failure analysis; but also more standard analysis of used material during charge/discharge process, including structural and electronic properties, and even robust, automated QC tests.
