The Cyclone Engine was deemed the Invention of the Year for 2008 by Popular Science magazine. It also won awards from the Society of Automotive Engineers in 2006 and 2008.

The Cyclone
Cost to Develop: $2 million
Time: 8 years
As long as the internal combustion engine has been around, garage tinkerers have been trying—in vain—to best it. But Florida boat engineer Harry Schoell, a lifelong inventor with a portfolio of patents, thinks he’s got the answer, in the form of a reinvented steam engine.
...
But steam engines small enough to fit in a car don’t typically produce enough energy to drive it. Schoell’s design, called the Cyclone Green Revolution Engine, gets more power from the steam by making it so hot that it turns “supercritical,” a stage at which it behaves more like a liquid and expands far more than gaseous steam.
Although it can scale up or down, Schoell’s prototype is roughly the shape and size of a backyard grill’s propane canister. Inside a doughnut-shaped combustion chamber at the top, fuel—be it biodiesel, ethanol or gasoline—combusts with air continuously to create a 2,000°F tornado (hence “Cyclone”). Steam circulates around a heat exchanger until it reaches 1,200°F and then pipes into the engine’s cylinders to drive the pistons. As the steam cools, it’s recycled back into the system and reheated.

Maybe it could be used with the plastic-into-oil gizmo :
