Methanol fuel is an alternative biofuel for internal combustion and other engines, either in combination with gasoline or independently. Methanol (CH 3 OH) is less expensive to sustainably produce than ethanol fuel, although it is more toxic than ethanol and has a lower energy density than gasoline.
Vapor lock is a problem caused by liquid fuel changing state to vapor while still in the fuel delivery system of gasoline-fueled internal combustion engines.This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling.
The aluminum alkoxide does not make a tight oxide layer; water is essential to repair the holes in the oxide layer. Methanol and ethanol are incompatible with some polymers. The alcohol reacts with the polymers causing swelling, and over time oxygen breaks down the carbon-carbon bonds in the polymer causing a reduction in tensile strength.
A self-sealing fuel tank (SSFT) is a type of fuel tank, typically used in aircraft fuel tanks or fuel bladders, that prevents them from leaking fuel and igniting after being damaged. Typical self-sealing tanks have layers of rubber and reinforcing fabric, one of vulcanized rubber and one of untreated natural rubber, which can absorb fuel when ...
Efforts are being made to convert "waste" natural gas into methanol, providing an efficient means of utilizing excess resources. While some methanol is produced by fermenting biomass, it is not yet economically competitive. Notably, M85 has the potential to be a preferred means of storing hydrogen for fuel-cell electric vehicles in the future.
If a cylinder fills with liquid while the engine is turned off, the engine will refuse to turn when a starting cycle is attempted. Since the starter mechanism's torque is normally much lower than the engine's operating torque, this will usually not damage the engine but may burn out the starter. The engine can be drained as above and restarted.
Combustion gases (unburned air/fuel mixture and exhaust gases) in each cylinder; Water-based coolant in the coolant passages; Lubricating oil in the oil galleries; Correct operation of the engine requires that each of these circuits do not leak or lose pressure at the junction of the engine block and the cylinder head. The head gasket is the ...
The use of methanol as a motor fuel received attention during the oil crises of the 1970s. By the mid-1990s, over 20,000 methanol flexible fuel vehicles (FFVs) capable of operating on methanol or gasoline were introduced in the US. In addition, low levels of methanol were blended in gasoline fuels sold in Europe during much of the 1980s and ...
