"It creates a kind of void that disrupts the fuel-air mixture."

They also plan to make engines that run on a leaner fuel-air mixture.

First the volume increases, which allows the fuel-air mixture to expand.

Valves open and close to allow the fuel-air mixture to enter the combustion chamber.

When the engine is running fast, the fuel-air mixture flowing into the cylinders has a lot of momentum.

This system uses less energy to form fuel-air mixtures, and releases more energy.

The ignition system is used to ignite the fuel-air mixture in the engine.

The fuel-air mixture must be brought almost to a stop so that a stable flame can be maintained.

However, the fuel-air mixture travels through a tube within the combustion zone.

Each section is filled with a different fuel-air mixture chosen so that later sections have higher speeds of sound.
