The temperature of the fuel system and the vapor over liquid volume ratio (V/L) that can be tolerated without vapor lock or hot fuel handling problems may vary from vehicle to vehicle.
Vapor lock happens in internal combustion engines as the methanol-gasoline vaporizes easier than that of gasoline under the same conditions.
Avgas has a lower and more uniform vapor pressure than automotive gasoline, so it remains in the liquid state despite the reduced atmospheric pressure at high altitude, thus preventing vapor lock. One of the noteworthy differences between avgas and mogas is the aviation fuel simply smells better.
Not only are rich people being affected by this economic vapor lock, we are, too.
Features include quick disassembly design for easy cleaning, no valves to clog or vapor lock, the ability to efficiently move viscous slurries and handle fluid temperatures to 400 [degrees] and solids up to one inch in diameter.
Additional features include: quick disassembly design for easy cleaning; no valves to clog or vapor lock; ability to handle thin liquids like soups and juices; efficiently moves viscous slurries like peanut putter, candies and jam; and ability to handle fuild temperatures to 400[degrees]F and solids up to one inch in diameter,
This internal fuel loop eliminates vapor lock and the need for an additional return fuel line.
Fuel vents: Blocked fuel vents can form a vapor lock that prevents gas from flowing out of that tank.
Pumps feature quick disassembly design for easy cleaning, no valves to clog or vapor lock and the ability to handle thin liquids, like soups and juices.
Other features include regenerative service braking for energy recovery and reduced friction brake maintenance, a variable retarding mode to sustain long downhill grades to keep friction brakes at a reasonable temperature, a hill-holding mode following the release of the friction brake and braking modes for long downhill grades to prevent traditional brake fade and vapor lock. Tunable torque ramp-up eliminates acceleration or braking jerks for greater passenger comfort and instantaneous torque distribution to each wheel across the "zero to max torque range.
The pulse-bypass system can operate accurately down to zero flow and will never vapor lock, making them ideal for stations that may periodically cease operation or go to extremely low flow.
