Not exact matches

The spent exhaust gasses provide a means by which to control the burn process thus reducing the heat in during the combustion process.

During the 24 hours of the Le Mans race, each car will be given a «fuel energy allocation» per lap, differing slightly depending on whether the internal combustion element is fuelled by petrol or diesel.

While the batteries of the S 400 HYBRID and S 300 BlueTEC HYBRID as autonomous hybrids are charged during braking or coasting or by the combustion engine, the new high - voltage lithium - ion battery of the S 500 PLUG - IN HYBRID has ten times the energy content and offers the option of being recharged from an external source with a charging socket located on the right side of the rear bumper.

The comment, made during a Jan. 17 interview with the editorial board of The San Francisco Chronicle, essentially explains how the kind of cap and trade mechanism sought by both Mr. Obama and Senator John McCain (the latter at least in his platform, if not on the stump) would make coal combustion ever more costly (unless the world finally gets serious about investing in large - scale testing and deployment of systems for capturing and burying carbon dioxide).

Natural gas is widely considered to be an environmentally cleaner fuel than coal because it does not produce detrimental by - products such as sulfur, mercury, ash and particulates and because it provides twice the energy per unit of weight with half the carbon footprint during combustion.

And for those of you who want to insist that aerosols produced by the uncontrolled burning of coal neutralized the effects of AGW from 1940 to 1979, please explain how the same argument could not be made for the effects of coal - induced aerosols during this earlier period, when no constraints on the polluting effects of coal combustion were present at all.

During that same period, 282 PgC were released by combustion of fossil fuels, and 5.5 additional PgC were released to the atmosphere from cement manufacture.

By process of elimination, there is net flow of CO2 into vegetation / land (with emissions from them being overall negative aside from fuel combustion), which is unsurprising in contexts ranging from a multitude of studies on co2science.org to how satellite - measured global net terrestrial primary production increased by several percent per decade during the period of global warming (Nemani et al. 2003, for instanceBy process of elimination, there is net flow of CO2 into vegetation / land (with emissions from them being overall negative aside from fuel combustion), which is unsurprising in contexts ranging from a multitude of studies on co2science.org to how satellite - measured global net terrestrial primary production increased by several percent per decade during the period of global warming (Nemani et al. 2003, for instanceby several percent per decade during the period of global warming (Nemani et al. 2003, for instance).

«THE stable carbon isotopic (13C / 12C) record of twentieth - century tree rings has been examined1 - 3 for evidence of the effects of the input of isotopically lighter fossil fuel CO2 (δ 13C ~ -25 ‰ relative to the primary PDB standard4), since the onset of major fossil fuel combustion during the mid-nineteenth century, on the 13C / 12C ratio of atmospheric CO2 (δ 13C ~ -7 ‰), which is assimilated by trees by photosynthesis.

Based on projected world energy requirements, the United Nations Department of Economic and Social Affairs (1956) has estimated an amount of fossil fuel combustion by the year 2000 that with our assumed partitions would give about a 25 percent increase in atmospheric CO2, compared to the amount present during the 19th Century.

Fires end up contributing to warming by releasing carbon dioxide during combustion.

The report, The Human Cost of Weather - Related Disasters 1995 - 2015, is intended to focus attention during the UN climate change conference — which opens in Paris on Monday − on the damage already inflicted by global warming as a consequence of rising levels of greenhouse gases in the atmosphere, in turn as a consequence of the human combustion of fossil fuels and the destruction of the planet's forests.

Hence not surprising German engineers during the Nazi era explored technological innovations in hydro electricity, wind power, and combustion of hydrogen gas, to supplement coal, still beloved by Merkel's Germany to this day!

The ratio of carbon to heat content was computed for each of the 5,426 selected coal samples by coal rank and State of origin under the assumption that all of the carbon in the coal is converted to carbon dioxide during combustion.

Old stoves and fireplaces are inefficient; if you're going to be burning wood to keep warm during the winter, the green thing to do is to make sure that as much of the heat that is produced by combustion is released into your home and isn't going out the chimney.

The automobile had been invented and entered mass production in the early 1900s, but just as the internal combustion engine started to prevail over electric cars at that time and mass production took hold with Ford's Model T bringing some cars and trucks into upper middle class households and into use by businesses and farms, the Great Depression and World War II dramatically reduced private personal consumption, so for the two decades from about 1929 until the several years after World War II that it took to convert factories from war production to civilian peacetime production, the automobile industry's private sector sales were greatly suppressed, domestic civilian road and bridge construction came to a near halt during World War II as government funds were diverted to the war effort, and domestic oil consumption was likewise suppressed.
