We offer petroleum oil. petroleum diesel, also called petrodiesel, or fossil diesel is produced from the fractional distillation of crude oil between 200 oc (392 of) and 350 oc (662 of) at atmospheric pressure, resulting in a mixture of carbon chains that typically contain between 8 and 21 carbon atoms per molecule. use as vehicle fuel :unlike petroleum ether and liquefied petroleum gas engines, diesel engines do not use high-voltage spark ignition (spark plugs). An engine running on diesel compresses the air inside the cylinder to high pressures and temperatures; the engine generally injects the diesel fuel directly into the cylinder, starting a few degrees before top dead center (tdc) and continuing during the combustion event. The high temperatures inside the cylinder cause the diesel fuel to react with the oxygen in the mix (burn oroxidize), heating and expanding the burning mixture to convert the thermal/pressure difference into mechanical work, i.e., to move the piston. a disadvantage of petroleum diesel as a vehicle fuel in cold climates, compared to gasoline or other petroleum-derived fuels, is that its viscosity increases quickly as the fuel's temperature decreases, turning into a non-flowing gel at temperatures as high as -19 oc (-2.2 of) or -15 oc (5 of), which cannot be pumped by regular fuel pumps. another disadvantage of diesel engines compared to petrol/gasoline engines is the possibility of runaway failure. Since diesel engines do not require spark ignition, they can sustain operation as long as diesel fuel is supplied. use as car fuel :diesel-powered cars generally have a better fuel economy than equivalent gasoline engines and produce less greenhouse gas emission. Their greater economy is due to the higher energy per-litre content of diesel fuel and the intrinsic efficiency of the diesel engine. Biodiesel-powered diesel engines offer substantially improved emission reductions compared to petroleum diesel or gasoline-powered engines, while retaining most of the fuel economy advantages over conventional gasoline-powered automobiles. However, the increased compression ratios mean there are increased emissions of oxides of nitrogen (nox) from diesel engines. This is compounded by biological nitrogen in biodiesel to make nox emissions the main drawback of diesel versus gasoline engines.
