Converting to Biodiesel

Compared with the mental and mechanical gymnastics involved in converting your car or truck to propane or Flex Fuel, converting your diesel-powered car or truck to biodiesel is a breeze just fill the tank with a biodiesel fuel. According to the DOE, the various biodiesel blends available can be used in any light- or heavy-duty diesel engine. That being said, some auto manufacturers are a little antsy about biodiesel fuel being used in their engines, so check with your owner's manual so you...

Guide to Current Hybrid and Alternative Fuel Models

The automotive world is ever-changing. Models go into production and out of production on a frequent basis, but the accompanying chart is a comprehensive look at the hybrid and alternative fuel vehicles available on the market today. More, of course, are coming as auto manufacturers from around the world try to tap into consumers' desires for better fuel economy, lower emissions, and less consumption of precious fossil fuels. Because of this, it is expected that in the coming months you will...

Electric Cars Round

Anderson built what is generally regarded to be the first electric vehicle. Unfortunately for Anderson (and our air quality), battery technology at the time had not advanced to the point of creating a rechargeable battery. The batteries in Anderson's car had to be replaced when they materials into a solution that conducts electricity. Because of a phenomenon known as electrolysis, electrons flow materials into a solution that conducts electricity. Because of a phenomenon known as electrolysis,...

The Pluses and Minuses of Hybrid Vehicles

The media has been very vocal about the pluses of hybrid electric vehicles. The fuel economy they deliver is amazing versus that of a conventional car, and because of this, they can help us limit our use of increasingly scarce and expensive petroleum. Fuel economy is often at least 25 percent better than for similar gasoline-powered vehicles. HEVs also pollute much less than conventional vehicles. Estimates indicate that hybrids can deliver emission reductions of as much as 50 percent for...

How Much Oil Is There

Okay, the oil supply is finite and we're using a whole lot of it. Finally, let's examine the third postulate because that's the really frightening one Pretty soon we're going to run out. That seems to be a commonly held belief. For instance, a Wikipedia.com author says flatly in his or her discussion of petroleum and petroleum-related issues, At current consumption levels, world oil supply will be gone in about 33 years. Now that's the kind of information that will get you up off your couch...

The Pluses and Minuses of New Diesel Vehicles

The key advantages new diesels offer are improved greenhouse gas emissions and potentially lower overall fuel costs based on the fact that diesel engines are inherently more efficient than gasoline engines. It should be noted that in terms of what are best termed more traditional pollution-causing emissions, including carbon monoxide, nitrous oxides, and particulates, clean diesel technology combined with the use of conventional diesel fuel simply equals the best conventional gasoline engine...

The Pluses and Minuses of Battery Powered Electric Vehicles

Electric vehicles, especially pure electric BEVs, are the darlings of hardcore environmentalists because they don't pollute. Period. There are no tailpipe emissions at all. How could there be There are no tailpipes. And the evaporative emissions are so small, they're not even worth noting. Greenhouse gas emissions Forget it. BEVs are clean, clean, clean. That being said, the electricity that goes through the grid and into the storage batteries of each electric car has to come from somewhere....

Multi Displacement Active Fuel Technology

In addition to PZEVs, another gasoline engine technology has recently gone into production that is designed to reduce fuel consumption, and it is being used on some of the largest, most fuel-thirsty vehicles on sale in the United States. Called variously Multi-Displacement System system allows engines to operate in two separate modes one with full cylinder operation and the other with partial cylinder operation. The industry catch-all term for the technology is displacement-on-demand DoD . An...
