36LeefH2 wants to clean up pretty much every diesel engine

Imagine if a little bit of water could make your internal combustion engine run cleaner and more efficiently, and help it produce more oxygen than a tree. That's what the LeefH2 device is designed to help your motor do. HNO Green Fuels, the maker of the LeefH2, wants to turn your engine – and every other combustion engine – into an oxygen farm while reducing particulate matter and getting more power out of your fuel.

13EPA's $9M clean diesel campaign could pay back $117M in health benefits

Diesel fumes are bad for people. But diesel power is good for a lot of heavy-duty work. So, for now, one answer to threading the needle of that little conundrum is to make diesel engines as clean as possible. To that end, the US Environmental Protection Agency (EPA) has announced $9 million worth of grant funds from the DERA National Funding Assistance Program. If the EPA's numbers are correct, that money could be worth something like $117 million in public health benefits.

AddFinnish company Pegasor introduces real-time particulate sensor for diesel engines

Biodiesel is still in limbo here in the U.S., but even if we never return to large scale production, at least diesel vehicles can continue to get cleaner on their own. The latest example of cleaner diesel tech news comes from Finland, where Pegasor Ltd. has introduced a new, compact, continuously operating and real-time particulate matter (PM) sensor, known as PPS-M. Pegasor, which sounds like the name of really bitchin' one-legged T-Rex, says that the sensor can be installed in the engine exhau

AddCalculating the cost of cleaner cars

When discussing the expense of buying an electric or hybrid car, it seems too often the costs taken into consideration are merely short-term monetary ones. However, a new study published in the New England Journal of Medicine last week makes it clear that there are some savings to be realized that go far beyond filthy lucre. Its findings reveal that cleaner air directly correlates to a longer life. For instance, of the three year increase in the average American lifespan between 1978 and 2001, t

AddGeneral Motors Medium Duty Trucks reduce diesel emissions

General Motors has announced its Medium Duty Truck lineup for the 2007i (the i stands for interim) and 2008 model years feature increased performance, increased driver comfort and reduced diesel emissions. Included are an all-new Chevrolet and GMC W-Series, as well as revised diesel engines and exhaust systems to ensure GM medium-duty trucks meet new, more stringent federal and state of California diesel as emissions standards.
