30 MPG 2014 Jeep Grand Cherokee Has Some Calling “Bulls**t”

I’ve been reading up on the news, a little, and it seems odd that while some makers garner rave reviews when they release a 47 mpg hybrid, such as the Ford C-Max, other makers get dumped on when they release a 30 mpg SUV, such as the just-revealed 2014 Jeep Grand Cherokee. 18 days into […]

LiquidPiston’s Prototype Proves ICE Technology Can Save Gas

The typical internal-combustion engine [ICE] is no more than 30% thermodynamically efficient, that is, only about 30% of the energy in the fuel actually does any work propelling the vehicle. The rest is lost to heat and friction, which seems to make ICEs a poor choice when it comes to energy-efficient transportation. Electrified vehicles might […]

Ciatti's Gasoline-Burning Diesel Engine Emits Less Soot and Nitrous Oxides

Diesel and gasoline engines have been the only way to move around since the 19th century (maybe with some small, electric exceptions for a short while). Though having low efficiency numbers (20 percent) when compared to their counterparts, gasoline engines still found their place on the market, mostly because in the first hundred years they had the advantage of being quicker, more responsive and now for not emitting soot and nitrous oxides.

Engineers from the Technische Universitaet Munchen (TUM) have shown an engine prototype whose emissions are very close to the Euro 6 standard, even though the Euro 5 norm has just been put into force three months ago for all new car models.

Cheap New Electrochemical Flue Gas Purificaton for Diesel Engines

Florin — Wed, 04 Feb 2009 05:37:28 +0000

In Europe half of the cars sold are using diesel engines. The pollution from these cars (carbon particles, nitrogen oxides NOX and unburned hydrocarbons) is to be more strictly restricted by the EU regulations.

RisÃƒÆ’¸ Danish Technical University has started a new project to develop an effective method for making diesel engines cleaner.
