As tightening emission rules force the car industry to embrace battery power, a German startup says it has the technology to give the combustion engine a reprieve.

Using pulsed microwaves to ignite fuel rather than spark plugs or glow plugs, the engineers behind MWI Micro Wave Ignition AG say they can cut consumption of gasoline and diesel by as much as 30 percent, and emissions by as much as 80 percent, because the fuel burns at a lower temperature.
