What is the fuel value of methanol?
22.7 MJ/kg
Heat Values of Various Fuels
| Heat value | |
|---|---|
| Methane (CH4) | 50-55 MJ/kg |
| Methanol (CH3OH) | 22.7 MJ/kg |
| Dimethyl ether – DME (CH3OCH3) | 29 MJ/kg |
| Petrol/gasoline | 44-46 MJ/kg |
What is the best air fuel ratio for methanol?
Typically, a rich methanol AFR is around 5 to 1 for a high-compression naturally aspirated racing engine with mechanical fuel injection (MFI)….By The Numbers: Tuning Fuel Injection with Air/Fuel Ratio and Lambda.
| Fuel | Stoichiometric AFR | Stoichiometric Lambda |
|---|---|---|
| Ethanol | 9 to 1* | 1.0 |
| Methanol | 6.5 to 1* | 1.0 |
Is methanol cheaper than petrol?
Methanol is the cheapest alternative fuel, compared to ethanol and petrol (gasoline), the findings from a NITI Aayog working paper released in September 2021, reveal.
What is the shelf life of methanol fuel?
Store methanol vials in a cool, dry environment, away from VOC sources. Methanol vials should not be stored for longer than 3 months. If the storage environment is potentially compromised, storage time should be less than 3 months.
How long does a tank of methanol last?
A larger tank should be considered if boost pressures of over nine psi are utilized in road racing, where a two-quart tank will run dry in as few as five to six two-mile laps. Under normal street use in a 400hp car, a two-quart tank will usually last about 450 miles.
Does methanol burn faster than gasoline?
Methanol Burns Cool Gasoline, when it undergoes a phase change can suck out about 150 BTUs of heat energy per pound of fuel, which results in a temperature drop. Methanol, on the other hand, takes 506 BTUs per pound of fuel of heat energy to make the phase change.
Does methanol make more power than gasoline?
Methanol versus gasoline is around 20% more powerful, and creates an alternative to gasoline. Methanol is hard to get, and can easily become contaminated simply from the moisture in the air. Gasoline engines produce 53,176 BTU’s of energy at 6500 rpm, whereas methanol engines produce 67,545 BTU’s of energy at 6500 rpm.
Which is a better fuel methanol or ethanol?
The comparison between the decrease in HC emissions and the blended fuels indicates that methanol is more effective than ethanol. The lowest HC emissions are obtained with methanol-blended fuel (M50). When more combustion is complete, it will result in lower HC emissions.
Does methanol lose potency?
as long as its not exposed to the elements and its stored in an air tight container that is compatable with methanol, the shelf life is indefinite.
Does methanol degrade over time?
Can you blend methanol with diesel?
Pure methanol cannot be used directly in unmodified diesel engines because it will require spark or ignition assistance or a fuel additive. However, use of diesel blended with up to 20% of methanol by volume requires only minor engine modifications (Lin & Chao, 2002).
Which alcohol is the most efficient fuel?
Ethanol also called as grain alcohol or ethyl alcohol. The purest form of ethanol is colorless liquid, flammable and boiling point 78.5°C. Compared to many other fuels, ethanol burns more cleanly and produces carbon dioxide and water. Hence, ethanol was considered as eco-friendly fuel for transportation process.
How much more power does methanol make?
What is brake-specific fuel consumption?
Brake-specific fuel consumption. Brake-specific fuel consumption (BSFC) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft power. It is typically used for comparing the efficiency of internal combustion engines with a shaft output.
What is the BSFC for brake specific fuel consumption?
The lower the brake specific fuel consumption, the more efficient the engine is. For spark ignition (gasoline engine) the BSFC is around 250 g/kWh and for compression ignition (diesel) around 200 g/kWh.
What units are used to measure fuel consumption?
In traditional units, it measures fuel consumption in pounds per hour divided by the brake horsepower, lb/ (hp⋅h); in SI units, this corresponds to the inverse of the units of specific energy, kg/J = s 2 /m 2 . It may also be thought of as power- specific fuel consumption, for this reason.
What is the fuel mass flow rate of the engine?
Usually, the fuel mass flow rate is measured in [g/s], the engine power in [kW], which gives the brake specific fuel consumption in [g/kW·h]: Engine power is the product between engine speed and torque. Therefore, we can express the BSFC function of engine speed and torque.
