What are the properties of diesel fuel?
Diesel Fuel Properties
- Ignition quality: cetane number and cetane index.
- Density (and gravity)
- Heating value.
- Volatility (distillation temperature)
- Viscosity.
- Low temperature operability properties, such as cloud point, pour point, cold filter plugging point (CFPP), and low temperature flow test (LTFT)
- Flash point.
Can you put diesel in a fuel cell?
Within FCGEN (Fuel cell based power generation), researchers successfully developed an on-board diesel fuelled fuel-cell system providing efficient electric power in trucks. On-board fuel reforming eliminates the need for hydrogen infrastructure as the APU uses the same fuel as the main engine.
What are the properties of the fuel?
Density, viscosity, heating value, flash point, acid value, pour point, cetane number, etc. are considered as the most important properties of a fuel for its application in engine. These properties indicate the quality of the fuel.
What type of fluid is diesel?
2.3. Diesel fuel is the liquid fuel used in diesel engines (a compression engine as opposed to the automobile spark ignition engine), and the most common is a specific fraction distilled petroleum, generally boiling (within the boiling range of fuel oil) between 200–350 °C (392–662 °F) at atmospheric pressure.
What are the properties of petrol and diesel?
Comparison chart
| Diesel | Gasoline (Petrol) | |
|---|---|---|
| Torque (for 10L engine) | 1000 Nm @ 2000 rpm | 300Nm @ 4000 rpm |
| Power (for 10L engine) | 490Hp @ 3500 rpm | 600Hp @ 5500 rpm |
| Power = torque*RPM | More torque at low speeds | Runs at higher RPM |
| Auto-ignition temperature | 210°C | 246°C |
What is the pH of diesel fuel?
between 5.5 and 8.0
pH. The normal pH for diesel fuel should be between 5.5 and 8.0. The lower the pH, the higher the potential for corrosive damage to metal components. Overgrowth of microbes is the main contributor to diesel fuel acidity.
Does diesel make electricity?
The diesel generator is the combination of two components, a diesel engine with an electric or electromagnetic generator (often an alternator) working together to generate electrical energy. This high speed motion causes an electric current to be produced.
What is hydrocarbon fuel cell?
Hydrocarbon fuels are used in high temperature operated solid oxide fuel cell (SOFC). In order to exploit the advantages of other fuel cells systems such as PEMFCs, their operating temperature should be increased if hydrocarbons are the fuel.
What is the composition of diesel fuel?
Diesel fuel consists mainly of paraffins, aromatics and naphthenes. The hydrocarbons of gasoline contain typically 4-12 carbon atoms with boiling range between 30 and 210 °C, whereas diesel fuel contains hydrocarbons with approximately 12–20 carbon atoms and the boiling range is between 170 and 360 °C.
How do you identify diesel?
Diesel or petrol car: How can I tell?
- Look for a sticker. Rental companies often put stickers in different places around the car to tell you which fuel to use.
- Check the model name. There might be a clue on the back of the car itself.
- See if the fuel pump will fit.
What is the viscosity of diesel fuel?
2.5–3.2 cSt
2 diesel fuel has a viscosity in the range of 2.5–3.2 cSt at 40°C, and biodiesel consisting of the methyl esters of soybean oil has a viscosity between 4.2 and 4.6 cSt (1,3–6).
What is the difference between diesel and petrol fuel?
Both petrol and diesel engines are internal combustion engines. The difference between petrol and diesel is found in the way that the combustion occurs. Whilst a petrol engine combines fuel with air before being ignited by spark plugs, in a diesel engine the air is compressed beforehand and then the fuel is injected.
What is the chemical composition of diesel fuel?
Diesel fuel no. 1 and no. 2 are similar in chemical composition to fuel oil no. 1 and fuel oil no. 2, respectively, with the . exception of the additives. Diesel fuels predominantly contain a mixture of C. 10. through C. 19 . hydrocarbons, which include approximately 64% aliphatic hydrocarbons, l-2% olefinic hydrocarbons,
Why is biodiesel better than diesel for lubrication?
Biodiesel fuel has chemistry similar to some lubricity additives and when blended with diesel fuel provides significant improvement to the fuel’s lubricating properties, in many cases eliminating the need for additional lubricity additives.
What are the properties of a diesel engine?
Diesel engines were developed to take advantage of the high energy content and generally lower cost of diesel fuels. Diesel fuel has various properties that need to be maintained to operate effectively in today’s modern diesel engines.
What is the specific gravity of diesel fuel?
Physically, diesel fuel appears as a colorless to light brown liquid with a specific gravity of 0.81 to 0.96, making it less dense than water. Diesel fuel freezes at negative 8.1 degrees Celsius, which is 17.5 Fahrenheit, rendering it less suitable for cold weather applications when compared to gasoline.
