FRANK MARCUS – 5/19/2020 Cutting-edge tech aims to increase efficiency and reduce emissions. When you boil it down, improving average fuel economy is super simple: Burn less fuel in the cylinder when cruising. Toward that end, engine developers have toiled to make lean mixtures work since way before Chrysler’s Electronic Lean-Burn System of the mid-’70s. But getting such mixtures to …

We’ve been using spark plugs to ignite fuel inside of engines for over 100 years. Maybe it’s time to change that. Transient Plasma Systems (TPS) developed a system that uses fast pulses of plasma, an electrically charged gas, at a low temperature to ignite all sorts of fuels. The low temperature improves thermal efficiency and the whole process requires less …
