The diesel engine also known as a compression-ignition or CI engine , named after Rudolf Diesel , is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to the mechanical compression adiabatic compression. This contrasts with spark-ignition engines such as a petrol engine gasoline engine or gas engine using a gaseous fuel as opposed to petrol , which use a spark plug to ignite an air-fuel mixture. Diesel engines work by compressing only the air. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites spontaneously. With the fuel being injected into the air just before combustion, the dispersion of the fuel is uneven; this is called a heterogeneous air-fuel mixture.

And the more we delay it, the higher will be the demand for carbon removal technologies in the future, he warns. Now, based on new scientific findings published by the Intergovernmental Panel on Climate Change, the Federal Council at its meeting on 28 August has decided to set an even more ambitious target: Switzerland […]. In an effort to avoid emissions from air travel, teenage climate activist Greta Thunberg recently chose to sail across the Atlantic to attend a climate summit in New York in September. One option, if […].
