But also when it comes to combustion, the use of E10 in carburetor engines creates an additional problem. The fuel properties are in fact considerably affected by 10% admixture of ethanol, because ethanol has a lower combustion value than gasoline. This means that more ethanol is needed to achieve maximum combustion with a certain amount of intake air. So you actually need larger nozzles for carb engines.
Was this problem with 5% ethanol blending still to be solved chemically by adding slightly heavier hydrocarbons, when 10% is mixed in, that trick is no longer possible. Oh yeah; it may be that the inflammation also needs to be adjusted a few teeth.
E10 therefore actually needs a different fuel-air mixing ratio than the old 'real' gasoline. Which also smelled much better.
Few problems for new stuff. Cars with U9 on the license plate.
Most motorcycle manufacturers release the use of E10 for motorcycles that are equipped with a programmed electronic fuel injection system with a lambda control. The following happens here. The lambda signals in the exhaust gases that not enough gas has been burned, so there is still oxygen left. The engine management compensates for that.
And there are even more 'nice' side effects of the stuff. Ethanol also slowly eats up metal: oxidation of aluminum, copper, etc. And rust of harder metals, including an accelerated effect on stainless steel. In addition, it cleans (it's basically rubbing alcohol) which can cause bits of dirt (think sand, rust, metal, dust, mud, etc) to enter the carburetor, clogging it up. Spark plugs come to a standstill from rusting and poor or no more sparks due to the rust insulation. Incidentally, cars that you adjust to it do run faster, editor Kevin Houtzager added.
This winter we can still refuel our classics with ethanol-free gasoline such as Shell V-power, Q8 Super Plus 98 and Texaco Super Plus 98 or BP Ultimate t
