Prof. Rolf Reitz (center) and members of his student team with the RCCI-powered Saturn

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

The Hazumi concept points towards the new Mazda 2, which will be the first car to feature ...

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.

The all-new T4 is ready for rough rides

In 2012, Brazilian 4x4 manufacturer Troller, which was purchased by Ford Brazil in 2007, provided a sneak preview of what its next T4 utility vehicle would look like with its TR-X concept. It has now folded the look and feel of that concept into the new production T4, a 4x4 that is making other parts of the world beg Ford for a rebadged export.  Read More

CAMI's new US$60,000 Hydra Gator is a diesel-electric hybrid amphibious vehicle

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

The team observed reductions in emissions of NOx, particulate matter and greenhouse gases ...

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.  Read More
