They argued back and forth for a while, but this was the only piece of the conversation i heard. Vapour lock is niets meer of minder dan de gasbel die ontstaat bij het overgaan van de vloeibare naar een gasvorm van de benzine. He said that bringing fuel temperature down will help engine performance but that the colder and less gaseous fuel will wash lubricating oil off the cylinder walls and destroy the engine fairly quickly on a daily driver. The other coworker was laughing at him and told him that if he insulates his fuel rail and brings the fuel temperature down he will effectively destroy his engine. vapour lock, partial or complete interruption of the fuel flow in an internal-combustion engine, caused by the formation of vapour or bubbles of gas in the fuel-feeding system. It commonly occurs when a car has been idling or has been turned off and then back on. The use of motor vehicle gas (MOGAS) or aviation gas (AVGAS) in the operation of aviation piston engine increases the risk of vapour locking. Vapor lock is more common in older car models however, it became more predominant in carbureted. When it happens, it disrupts the correct air to fuel ratio and prevents fuel from reaching the specific fuel lines, resulting in engine stops. Vapor locks can occur in fuel-injected cars. Vaporized fuel creates back pressure in your fuel system and prevents gas from getting to your engine. Vapor lock happens when fuel overheats and turns to vapor in a fuel injector, fuel line, or carburetor. Carbureted gasoline cars with an engine-driven mechanical fuel pump are most susceptible to vapor lock. They said adding insulation to the fuel rail would keep the fuel temperatures lower which would keep octane levels up and intake temperatures down a little. Vapor lock happens when your fuel boils in your carburetor or your fuel line. One of them was arguing that their car needed it, that they had measured the heat of their fuel rail and that it was much too hot. What Is Vapor Lock Vapor lock occurs when fuel overheats and vaporizes in a fuel line, carburetor, or fuel injector, disrupting the correct air-fuel ratio. The other day I overheard my coworkers arguing about insulating a fuel rail. That being said I am an extremely curious person. ![]() Though admittedly I do not know all the ins and outs of lubrication and engine mechanics.
