Audi Engineers Use Glass Combustion Chamber to Test New Synthetic Fuel

Boldride

Like any other big name automaker, Audi is working on a new synthetic fuel to make driving more economical. But there’s one thing that Audi engineers are using that no one else is – glass. No, not in the fuel, but in the actual testing process.

Usually hidden behind a metal cylinder, the process of combustion is a crucial part in understanding how fuels interact inside the engine. Using quartz glass, Audi engineers have created a way to see this process firsthand and give them a better idea of how their fuels are reacting. We’ll let Audi explain exactly it works:

“During each of up to 3,000 revolutions per minute in the research engine, a minute amount of fuel shoots into the glass cylinder, is compressed and ignited, and the exhaust gas then expelled.”

Sounds simple enough.

But what does this tell Audi engineers? It shows that Audi’s synthetic e-fuels are absolutely pure, more so than the standard fossil fuels. This leads to fewer emissions and longer sustainability.

Plain and simple — glass combustion chambers are giving Audi engineers a whole new perspective on how internal combustion works.
