Toyota is hot on hydrogen fuel cells for its next-generation cars, but it’s not going cold on internal combustion just yet. The company’s R&D division has developed a Free Piston Engine Linear ...

Free-piston engine generators and linear machines represent an innovative departure from conventional rotary systems, offering high thermal efficiency and operational flexibility by eliminating the ...

There is probably no better chronicler into the full depth of American ingenuity than YouTube. Here one finds not just computer models for all manner of esoteric combustion engine designs, but actual ...

It’s pretty obvious that electricity is the future for our cars. But as any EV owner now can tell you, it has some limitations. Range and charging times are their biggest limitations, but the Toyota ...

Technically, the combustion engine in any hybrid vehicle is a range extender, but the term commonly refers to gasoline-fueled generators that are used to charge an electric vehicle’s battery pack but ...

Mainspring Energy has adapted its linear generators so they can run on hydrogen or ammonia fuel, on top of widely available fuels such as natural gas and biogas. “The generator has passed key tests to ...

A linear generator can switch between a variety of fuel types without losing efficiency. The creation of this generator began in the Stanford Advanced Energy Systems Laboratory. Mainspring Energy ...

Despite the recent advent of usable, talented electric vehicles, combustion engines are likely to persist for quite some time, often as a component in plug-in hybrid and range-extended electric ...

Antony Ingram April 30, 2014 Comment Now! The concept of range-extended vehicles--electric cars with a gasoline generator to extend their range--is an intriguing way of combining the benefits of both ...

Israel's Aquarius Engines this week gave the world a first look at the tiny hydrogen engine it hopes can supplant gas engine-generators and hydrogen fuel cells in future electrified vehicles. Weighing ...

We developed a high-efficiency linear generator powered by hydrogen, which has less friction than rotating engines by turning linear motion directly into electricity. They are applicable as a range ...
