FEV testing finds Transient Plasma ignition system increases fuel efficiency and decreases emissions

Green Car Congress

TPS) nanosecond pulsed power ignition system ( earlier post ) on the current Toyota 2.5-liter, liter, direct and port fueled injection, inline 4-cylinder gasoline engine commonly used in the Camry line of vehicles. The Toyota 2.5L engine was tested at FEV North America and results indicate improvements over the stock ignition system.

JATO: new car CO2 emissions rise for the first time in a decade in Europe; diesel down, gasoline up, SUVs up

Green Car Congress

This rise in average CO 2 emissions correlates with a decrease in demand for diesel cars across Europe—which produce lower CO 2 emissions than gasoline cars—and the rising popularity of SUVs, which emit higher average CO 2 emissions of 133.0 g/km, compared to gasoline cars, which had an average of 123.4 g/km CO 2 emitted.

Are Toyota, Mazda, and Subaru Doing the Right Thing By Snubbing EVs?

The Truth About Cars

The event was hosted by a trio of Japanese CEOs and their top engineers to explain to the world how they planned on tackling emissions regulations without being overwhelmingly reliant on battery electric automobiles. That was its plan for cleaner, downsized 1.4-liter It then griped about the automakers not having provided fresh ideas.

Hybrids vs EVs: where should government put its money

Baua Electric

To accomplish this goal, while other technologies have emerged, EVs (electric vehicles) and hybrids have become the most well-known and broadly accepted, particularly in India. While both EVs and hybrids are doing well in the Indian automobile market, there is a debate among automakers about which technology is cleaner.
