Why the days of the internal combustion engine are NOT over

July 5, 2011, GigaOM Cleantech

Here's some sobering news out of the raucous fourth of July weekend: considering battery prices and $4.50 per gallon gasoline, it'll take a little under 6 years for a hybrid car to pay off in fuel savings, and 8 years for an electric car, according to this report in the Wall Street Journal. At that rate of battery innovation, and if gas prices don't climb, then plug-in cars will remain largely financially not viable for most buyers in the U.S. for years to come. That's not good news for electric car makers, but could actually be a driver for companies building new, more efficient, internal combustion engine technology...Other companies that I've covered that are developing more efficient engines include Pinnacle Engines, which makes a four-stroke engine that it says can deliver 30 to 50 percent better fuel economy, and could be commercialized by 2013. Another is Achates Power, which is building a closed piston, 2-stroke engine that gets 10 to 15 percent better fuel economy than state of the art diesel engines that exist today.

Pinnacle Engines Aims to Slash Fuel Consumption by 25 to 50 Percent

June 29, 2011, Greentech Media

Although electric cars tend to grab most of the headlines, established companies and a select group of startups like Achates Power and EcoMotors are tinkering with ways to improve the efficiency of internal combustion engines.

"Pistons stay cooler and less heat is rejected than in current four-stroke diesels, which allows use of a smaller cooling system. Lab testing shows the Achates has 12 to 16 percent better brake-specific fuel efficiency. And if a modern four-stroke diesel's thermodynamic efficiency is 45 to 46 percent, then the Achates engine's "is on the order of 50 percent, and we have a road map to go to 55 percent," says Achates' president, David Johnson."
