Linear hydrogen engine as a range extender for e-cars

A linear motor powered by hydrogen comes from Aquarius Engines in Israel. As a generator drive, it can increase the range of electric cars.

Aquarius Engines deals with the production of clean energy and relies on hydrogen as an energy source. The Israelis have developed a linear motor that uses hydrogen as fuel. The linear motor is primarily intended for use in stationary energy generators. However, since it is very compact with a length of just under one meter and weighs very little at 10.5 kilograms, it can also be integrated directly into electric cars as a generator drive.

Extremely simple construction

There, the linear motor could drive a generator and thus supply electricity for an electric motor or to recharge a battery. To put it simply, the Aquarius linear motor, like any other linear motor, relies on a type of piston that is firmly mounted on an axis. It moves linearly back and forth through the engine, alternating between two combustion chambers in a two-stroke cycle. The mixture is supplied with overflow channels. Overall, the complete engine consists of only 20 components, of which only one moves.

The air-cooled linear motor, which by design does not require an additional lubrication circuit, should be extremely low-maintenance, have little internal friction and be able to run at very low "speeds" (nothing turns here, of course). The engine can also be easily adapted to a wide variety of fuels. In addition to hydrogen, LPG or CNG and, of course, conventional petrol can also be burned.,

Aquarius Engines specifies an output of 16 kW for the stationary engine. Maintenance is only planned every 1,000 operating hours. Converted to a car use, that would be around 80,000 kilometers. No other dates have been mentioned so far.,

Conclusion

The Aquarius Engines linear motor sounds like a good approach for a range extender for electric drives. But here, too, the fundamental problem remains a lack of hydrogen infrastructure.
