Diesel fuel en590 50ppm

Diesel fuel is often used in diesel engines. Diesel engines or compression ignition engines, rely on the temperature increase of compression, rather than on spark plugs, to achieve reliable ignition timing and combustion efficiency.

As a result of their inherently higher compression ratio for a given power output, diesel engines are more fuel efficient than spark ignition engines. Compared with spark ignition automotive engines, diesel engines weigh more, generate more vibration and produce greater particulate or soot emissions. Diesel engines can also produce a particularly carcinogenic type of hydrocarbon pollutant known as polycyclic aromatic hydrocarbons (PAHs), which are generated during the diesel combustion process.
