What is Valve Meltdown, exactly?

What is valve melting? Why do engine valves melt? What can you do to avoid valve meltdown Do valve lubrication systems work? We need answers to ……. questions.

Valve meltdown in LPG can be a problem in Euro5 new-generation vehicles. So why do valves melt in LPG, then?

Now, steel alloy valves can be replaced with more eco-friendly and cleaner-operating magnesium valves. All Euro5 engines use magnesium alloy engines. The engine produces more power with less energy if it has lighter moving parts. Magnesium lightens engine components and reduces fuel consumption. LPG vehicles have magnesium alloy valves that can travel 20 000 km. It begins to melt when it is used. For some cars, this is 50 000 km. You can get up to Valve ratios that vary depending on the vehicle’s brand.

What happens to Magnesium when LPG is melted in Valves?

Automobile manufacturers create vehicles for gasoline. Magnesium valves are not affected by the heat produced in an engine that uses gasoline. LPG is more flammable that gasoline so the engine is subject to higher temperatures. Old-generation steel alloy valves can withstand the heat better than modern ones, but magnesium valves tend to be more damaged.

Steel begins to melt at 1500 °C. The melting point of magnesium is 650 °C. The melting point of magnesium is 650 degrees Celsius. LPG can increase the vehicle’s engine temperature. Because you increase your vehicle’s speed, the temperature will rise, and melting will take place in less time.

What are Alternative Solutions?

Technically and theoretically, a valve meltdown in LPG is now accepted in Euro5 vehicles. The solution has been found in the form of valve lubrication systems. While it doesn’t resolve the problem immediately, it can slow down the melting process.

These systems can be produced electronically or manually. They cool the system by sending oil to specific valves at set intervals.

It can be considered an alternative to using ga at high speed to delay the melting.
