Experimental diesel/gas engine could give 2009 Saturn a big boost in fuel efficiency

Five years ago we first heard about a Caterpillar diesel engine located at the University of Wisconsin-Madison, that had been modified to run on an unlikely-sounding mixture of diesel and gasoline. Not only did the one-cylinder engine work, but it was more efficient than pure-diesel or pure-gas engines at converting the chemical energy of fuel into motion. Sitting in a basement lab, however, isn't the same as experiencing use in the real world. That's why students at UW-Madison, led by Prof. Rolf Reitz, have now put another diesel/gas engine into a 2009 Saturn. Read More

Mazda joins the downsizing party with 1.5-liter SKYACTIV diesel

In spite of the saying "ain't no replacement for displacement," manufacturers are making their engines smaller by the day. Ford has its 1.0-liter EcoBoost, and Mini a 1.5-liter three cylinder motor. Renault's next Twingo will feature not only a 1.0-liter engine, but a 900cc motor making 90hp. Now, Mazda has joined the global trend for downsizing engines with its new turbocharged 1.5-liter SKYACTIV diesel. After teasing us at the Geneva Motor Show, the Japanese car company has finally released details of its new motor. Read More

Hydra Gator: US$60,000 diesel-electric hybrid amphibious vehicle surfaces

Amphibious Vehicle manufacturer CAMI has added yet another amphibious vehicle to its range: the hybrid-diesel-electric Hydra Gator. Unlike the existing amphibians already established in the range, the cheapest of which starts at US$275,000, the Gator will sell for just US$60,000 and though it cannot be used on-road, the tiny 4X4 can take four people just about anywhere else you wish – silently in electric mode, or for long distances using the diesel engine as a generator for the electric drives.Read More

New eco-hybrid fuel could help to reduce shipping pollution

The EPA has identified pollution from ships as a contributing factor to respiratory problems and premature deaths suffered by residents of the US and Canada. As such, it is in the process of implementing stricter emissions standards for ships operating within 200 miles (321.9 km) of shore with the aim of significantly reducing emissions by the year 2020. In a development that could play into these environmental initiatives, the SeaChange Group, a US-based start-up that converts agricultural by-products into clean-burning fuel, has been awarded a patent for an eco-hybrid fuel technology shown to reduce NOx, particulate matter and greenhouse gas emissions.
