摘要

Engine protection and fuel efficiency are not just about using the right lubricants. Fuels, which in Europi conform to EN590, have a part to play too, according to fuel firms. And, giving the example of FuelSave diesel - claimed to deliver 3% fuel economy improvement over baseline alternatives - Shell fuel scientist Emma Wyatt explains that the issues are much the same. "For example, Shell FuelSave diesel is formulated with special detergent chemistry to maintain the performance of the injectors by preventing deposits inside and around the injector tips," she says.And she points to the importance of ensuring spray symmetry for combustion efficiency, particularly as pressures and temperatures increase. Then there's corrosion prevention. "We formulate the additives to deliver a protective surface that shields it from water droplets. It's only a few molecules thick and it needs replenishment, but if it's in every fuel injection, it offers that protection." And it's a similar story with anti-foaming to speed up fill rates, and de-hazing, for operators that bunker bulk fuel and need to keep it fresh.
