A study analyzing real-world diesel vehicle emissions finds that NOx levels from modern engines far exceed the mandated limits. However, the carbon monoxide and total carbon hydrogen numbers are where they should be.
Critical Look At Diesel Engines Could Benefit Hybrids
Ford doesn't expect the Mondeo Hybrid to be a huge sales success in Europe. However, with governments there backing away from supporting diesel fuel, the sedan offers a hedge against future changes in the market.
The European Union is working on legislation to scrap the 25-year-old laboratory tests in the New European Driving Cycle that measure vehicle emissions, replacing NEDC with Real Emissions Driving tests.
A newly released study finds that the emissions from post-2007, EPA-compliant diesel engines do not show risks of causing lung cancer in lab rats. The animals were exposed to the exhaust for 80 hours a week for up to 30 months. Previous studies have shown much more adverse effects from older diesels.
Anyone even vaguely familiar with the European auto market knows that diesel-fueled vehicles take up a huge portion of the roads there. A combination of high fuel efficiency, useful torque in tightly packed cities, low CO2 emissions and tax incentives all contribute to the popularity. However, ever the iconoclasts, the French government wants the oil burners off its roads in the coming years.
In UK, Exhaust Emissions Kill More Than Crashes Do
That dirty look parents (OK, some parents) give a cigarette smoker blowing smoke towards their kids? Maybe those should extend to drivers of cars using conventional internal-combustion engines. Which would make for a whole lot of stink-eye.
European automakers are apparently a little off in their collective emissions ratings for their vehicles. Way off, actually. To the tune of $580 in refueling costs per driver. The vehicles likely emitted 38 percent more CO2 than what they were rated at, according to Bloomberg News, which cites a report by the International Council on Clean Transportation (ICCT), and that leads to the extra refueling costs.
Testing vehicle emissions in the laboratory is a way to guarantee identical procedures, but it doesn't exactly mimic the results from an on-the-road drive. Ford, for example, famously had a problem with dynamometer testing in the Total Road Load Horsepower (TRLHP) calculations for the C-Max Hybrid. Over in Europe, the authorities are considering new rules that will not affect the emissions levels that need to be reached (those are already in process) but how the vehicles will be tested. Reuters
In 2007, the European Union mandated fleet average CO2 emissions of 158.7 g/km. For 2015, that figure will drop to 130 g/km, and the target for 2020 is an ambitions 95 g/km. Thanks to some German politicking, that target will be phased in from 2020 to 2024, but it will still apply to 80 percent of passenger cars in that first year. In US miles per gallon, that's the equivalent of going from about 35 mpg to 42 mpg to 57 mpg. The current Volkswagen Golf is rated from 85 g/km of CO2 to 190 g/km dep
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.
When it comes to diesel trucks, the good old days weren't so good. Go back a quarter-century, for instance. Back then, a single diesel-powered truck was throwing off about 60 times the emissions a typical "clean diesel" truck does today. Cough.
Stands For World Light Vehicle Test Procedure, FYI
A hard job may be getting a little harder for European automakers looking to meet stricter emissions mandates. Automakers charged with cutting fleetwide emissions by about 27 percent by 2021 may have to shave off even more emissions by then if the European Union has its way. That's because the EU is looking at instituting a new testing program to measure emissions in a way that some analysts say is more accurate than the long-held New European Drive Cycle (NEDC) testing system, Automotive News E
In the late 1970s, performance cars suffered a huge blow when the necessity for better economy and lower emissions crippled their power. It took nearly a decade for the horsepower to return. Today, we're in the middle of another push for greater vehicle efficiency, but don't expect another era of malaise this time. Instead, lightweight materials, turbos and hybrids mean that everyone can be happy. However, the pressure to clean up isn't just for the mass market, supercars must improve too, but F
Electric Vehicle's ‘Global Warming Potential’ 40 Percent Lower
The heart of the matter is that the battery-electric Kia Soul is better for the environment. And not just because it doesn't create any emissions while on the road. From beginning to end, the Soul EV has a far lower environmental impact than its more conventional counterparts.
