November 26, 2016: Construction vehicles may soon become more efficient as well as environmentally-friendly in the future, as the scientists are developing some intelligent power systems for improved engine operation.

According to PTI, “Researchers at the University of Warwick in the UK are working to optimise the fuel economy of the next generation of off-highway vehicles.”
This could help in significant fuel savings and fewer carbon emissions for the industry.

Researchers are analysing the fleet of a company that manufactures equipment for agriculture, construction, demolition and waste handling to better understand the opportunities for the emissions reduction and intelligent control.

Researchers said, “Construction industry is more environmentally-conscious than ever and the amount of CO2 emissions released by vehicles is a significant factor in deciding which ones to use during an assignment.”

As a result, it is now important that all construction fleets reduce their emissions – so in an increasingly competitive market greener, and efficient vehicles will be more in demand.

According to PTI, “Researchers are analysing the suitability for micro/mild hybridisation (MMH) – a feasible solution that represents a simple, low-cost implementation to create high fuel efficiency with less energy use and fewer emissions.”

“Many off-highway vehicles are left running at full power whilst idle for much of their life – such as telescopic handlers, heavy excavators and wheeled loaders – potentially wasting fuel with a direct impact on local air quality.”

“The intelligent use of MMH could provide the opportunity to shut down the engine, or shift it to lower power, during these idle periods.”

Scientists are also researching on a pioneering technology which predicts when the machinery requires the shift between high power and low power, thus allowing the users to run the machine with lowest fuel consumption and without sacrificing their performance.

Based on the big data mining and knowledge from experts, an intelligence-based decision tool has been constructed, in order to enable companies to target specific machines among their fleets for hybridisation.

Emission of CO2 Levels Higher In Antarctica Than Believed

The team used the pH measurements to calculate the amount of dissolved carbon dioxide, and then uses that to figure out how strongly the water is absorbing or emitting carbon dioxide to the atmosphere.

The open water nearest to the sea ice surrounding Antarctica releases significantly more carbon dioxide in winter than previously believed, showed a study conducted using an array of robotic floats.

The robotic floats diving and drifting in the Southern Ocean around the southernmost continent made it possible to gather data during the peak of the Southern Hemisphere’s winter from a place that remains poorly studied, despite its role in regulating the global climate.

“These results came as a really big surprise, because previous studies found that the Southern Ocean was absorbing a lot of carbon dioxide,” said lead author Alison Gray, Assistant Professor at the University of Washington.

In the Southern Ocean region, carbon atoms move between rocks, rivers, plants, oceans and other sources in a planet-scale life cycle.

It is also among the world’s most turbulent bodies of water, which makes obtaining data extremely difficult.

According to the study published in the journal Geophysical Research Letters, the floating instruments collected the new observations. The instruments dive down to 1 km and float with the currents for nine days.

Next, they drop even farther, to 2 km, and then rise back to the surface while measuring water properties.

After surfacing they beam their observations back to shore via satellite.

Unlike more common Argo floats, which only measure ocean temperature and salinity, the robotic floats also monitor dissolved oxygen, nitrogen and pH — the relative acidity of water.

The study analysed data collected by 35 floats between 2014 and 2017.
