MISTRAL's dual electric fuel pumps

Multi-fuel

Replacing Avgas 100 LL: The future has started

MISTRAL engines are multi-fuel. They work on most grades of gasoline, leaded or unleaded, avgas or mogas, mixtures thereof, and can readily accept ethanol-blended fuels. You can switch between 100LL, unleaded 87 octane or higher, with no change to your engine or settings.

• unprecedented flexibility in fuelling options
• reduced average fuel bill

MISTRAL Engines is working hand in hand with partners to certify its engines with second generation biofuels capable of replacing avgas. Watch this website for news on progresses.

MISTRAL engines use multiple electronic fuel injectors and dual electric fuel pumps to ensure complete redundancy throughout the fuel injection system.

MISTRAL engines are relatively insensitive to knocking and have no critical points such as valve stems which require highly leaded fuel. Hence the engines can use a variety of fuels, such as 100LL Avgas, as well as unleaded mogas with an octane rating of 87 (US norm)/90 (European norm) or higher. You can actually switch between fuels, or mix them in any proportion, with no change to your engine or settings. The Digital Engine Management system automatically adjusts for you injection and ignition timing to compensate for differences in fuel quality.

While MISTRAL engines are operating perfectly on mogas, it must be noted that mogas is more prone than avgas to generate vapour locks in an aircraft fuel system at altitude. The propensity to develop vapour locks has nothing to do with the nature and model of the powerplant but everything to do with the design of the fuel system itself.

MISTRAL’s ultimate goal is to offer a kerosene line of engines, for experimental and certified markets. Developments are on their way in our lab. Check our News section for progress reports.
