coli), there have been a few research results on the production of long-chain alkanes, which consist of 13-17 carbon atoms, suitable for replacing diesel. There have been a few reports on the bio-based production of C 13 –C 17 long-chain hydrocarbons for substituting for diesel. Here we report the development of engineered E.
The drawback, as noted in a 2013 study by Ford researchers on GDI particulates, is that direct injection of fuel into the combustion cylinder risks liquid fuel impingement onto the piston and cylinder surfaces and inhomogeneous air fuel mixing; consequentially PM formation is higher than in conventional PFI gasoline engines.
BMW noted that in two studies carried out by the ICCT, results confirmed that the BMW X5 and 13 other BMW vehicles tested comply with the legal requirements concerning NO x emissions. BMW also took the opportunity to speak strongly in support of diesel in the context of the coming 2020 emission targets in Europe.
A new study carried out by University College Dublin (UCD) academics has found that under typical Irish commuting conditions, the Toyota Prius IV (fourth-generation) hybrid ( earlier post ) drives in zero emissions mode (ZEV) for significantly more than half (62%) of the time and more than 40% (40.4%) of the distance covered.
The trial sought to test whether businesses could carry out the typical daily duties of their diesel-powered vehicles, while maximizing the use of zero-emissions electric-only mode. liter EcoBoost petrol engine as a range extender for total range exceeding 500 kilometers (310 miles). l/100km (71.2
We are convinced that we will get a fantastic reaction from the people who use such vehicles on a daily basis: Electric mobility will allow them to travel in city areas which are now off-limits to petrol and diesel-powered vehicles and the range-extender technology makes it possible to use an electric van for normal routine business.
It is far too early to dismiss the conventional diesel and petrol power trains. In the last two years Volvo has brought CO 2 emissions from our diesel and petrol model ranges down by 13 percent. We continuously improve their efficiency. —Stefan Jacoby.
EV car searches up to THIRTY times more likely to result in a sale compared with petrol/diesel cars, says BuyaCar SEARCHES for electric vehicles (EVs) are up to 30 times more likely to result in a purchase than searches for conventional petrol and diesel-engined cars, according to a new study.
