Testing the cold start capability of an engine after three days in a cold chamber. (car maker facilities in the UK, 1945) Winter diesel fuel (also known as winter diesel, alpine diesel, or winterised diesel) refers to diesel fuel enhanced to prevent it from gelling in cold weather conditions. In general it is achieved by treatment with ...
The gel points of some common petroleum products are as follows: #1 diesel fuel: 15.5 °F (−9.2 °C). #2 diesel fuel: 17.5 °F (−8.1 °C). Heating oil: 16.0 °F (−8.9 °C). Kerosene: −40.0 °F (−40.0 °C). For the petroleum product to flow again, it needs to be brought above the gel point temperature to the ungel point, which is ...
Hydrocarbons in gasoline generally exhibit low acute toxicities, with LD50 of 700–2700 mg/kg for simple aromatic compounds. [117] Benzene and many antiknocking additives are carcinogenic. People can be exposed to gasoline in the workplace by swallowing it, breathing in vapors, skin contact, and eye contact. Gasoline is toxic.
Liquid nitrogen (LN2) is nitrogen in a liquid state at low temperature. Liquid nitrogen has a boiling point of about −196 °C (−321 °F; 77 K). It is produced industrially by fractional distillation of liquid air. It is a colorless, mobile liquid whose viscosity is about one-tenth that of acetone (i.e. roughly one-thirtieth that of water at ...
A diesel-fueled engine has no ignition source (such as the spark plugs in a gasoline engine), so diesel fuel can have a high flash point, but must have a low autoignition temperature. Jet fuel flash points also vary with the composition of the fuel. Both Jet A and Jet A-1 have flash points between 38 and 66 °C (100 and 151 °F), close to that ...
An antifreeze is an additive which lowers the freezing point of a water-based liquid. An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. [1] However, all common antifreeze additives also have lower heat ...
A blend of approximately 30% kerosene and 70% gasoline, it is known as wide-cut fuel. It has a very low freezing point of −60 °C (−76 °F), and a low flash point as well. It is primarily used in northern Canada and Alaska, where the extreme cold makes its low freezing point necessary, and which helps mitigate the danger of its lower flash ...
The venturi effect can reduce the air temperature by 39 K; 39 °C (70 °F). In other words, air at an outside temperature of 38 °C (100 °F), can drop to −1 °C (30 °F) in the carburetor. Carburetor icing most often occurs when the outside air temperature is below 21 °C (70 °F) and the relative humidity is above 80 percent. [ 1 ]
