What is a hot vapor engine?
Hot-vapor technology attempts to recapture this heat energy, using it to superheat the incoming air/fuel mixture to more than 450 degrees F going into the cylinder, thereby achieving a homogeneous, perfectly vaporized condition that’s said to prevent detonation while ensuring complete combustion.
What are the signs of vapor lock?
Symptoms of vapor lock in cars include engine stalling and difficulty starting, engine running rough, potential misfiring, and engine acceleration and hesitation. Your vehicle’s fuel system needs to operate under a certain pressure.
