How to measure gas, electricity and water using a gas-testing instrument

The CO2 emissions from the combustion of diesel and petrol engines can be measured using a measurement instrument that emits a gas of CO2, according to new research.

The Australian National University’s gas-sensing instrument, called the Gauge Measurement Instrument (GMI), can be attached to the front end of a diesel or petrol engine and measure the gas emitted by it, in addition to measuring the temperature of the fuel.

The research by the University of New South Wales (UNSW) team at the University Centre for Gas Technology (UCGTT) at the Australian National Engineering University (ANETU) found that the GMI can be used to measure CO2 levels in a range of fuel types, and it is now being used to analyse gas emissions from various vehicle types.

“We wanted to understand how emissions from diesel and motor vehicles were calculated, and how this was measured,” Associate Professor Andrew Williams, a postdoctoral researcher in the UNSW School of Chemistry, said.

“In a range that ranges from diesel to petrol, the GSU can also be used in conjunction with other emission measurement tools, such as those used in diesel-powered vehicles.”

The research involved analysing the gas that is emitted when a diesel engine is ignited, using a method known as a “gas flow graph”.

“The GSU is the only method that allows us to directly measure gas emissions at the combustion point, which is the point where the gas is being emitted,” Associate Dean of the UCGTT, Dr Chris Pryce, said.

“Our findings show that our new gas-flow graph measurement instrument can be applied to both diesel and other fuel types to calculate emissions.”

The results show that, by applying the Gsupt measurement instrument to a range range of fuels, we can derive a value for the CO2 level in the fuel.”‘

Very exciting’ The team found that by using their new technique, the value of CO3 in a fuel can be calculated from the value that is calculated for CO2 from the gas flow graph.”

By analysing a range which ranges from 0.05 to 0.3 micrograms per litre, the team found they could obtain values for CO3 at the CO 2 emission level in a large range of diesel-fueled vehicles,” Associate Associate Professor Williams said.

The gas that the researchers measured is a mixture of nitrogen oxides and hydrogen sulfide.

It has been known for some time that the gas released by combustion of fossil fuels is a significant contributor to global emissions, particularly CO2.”

It’s not only the CO and methane emissions from these fuels, but also the hydrogen sulfides and nitrogen oxide, which are a major contributor to climate change,” Associate Research Professor Williams explained.”

What we were interested in was how to relate this to how CO2 and methane are emitted in these fuels.””

The hydrogen sulfates are very interesting because they are relatively stable, but are very stable in the atmosphere, so we wanted to find out what happens when they are released into the atmosphere.

“In the future, the researchers plan to develop a new gas flow chart measurement instrument.

The work is published in the journal Science Advances.
