TheEarthbecame covered in a thin layer of lead, andlead is toxicto many living things (including humans). When lead was banned,gasoline got more expensivebecause refineries could not boost the octane ratings of cheaper grades any more.Airplanesare still allowed to use leaded gasoline, ...
Theoctane ratingof gasoline tells you how much the fuel can be compressed before it spontaneously ignites. When gas ignites by compression rather than because of the spark from the spark plug, it causesknockingin the engine. Knocking can damage an engine, so it is not something you want to ...
When lead was banned, gasoline got more expensive because refineries could not boost the octane ratings of cheaper grades any more. Airplanes are still allowed to use leaded gasoline (known as AvGas), and octane ratings of 100 or more are commonly used in super-high-performance piston airplane...
By shifting the ratchet back and forth, the blend valve can produce any octane of gas, ranging from the highest to the lowest grades stored in the tanks -- and all octanes in between. Keep reading to find out how the dispenser makes sure that you don't overflow the gasoline capacity ...
Do you buy the cheapest gas? No-name gasoline can be sub-standard, stick with a name brand gasoline and be consistent when possible. Higher octane is not always better, follow your owners manual and go with the recommended octane rating.More...
Gasoline:Just below the section headings are column headers containing specific grades or types of gasoline available, they generally reflect prices for regular, mid-grade and premium octanes. RVP: Just below your report’s date stamp, gasoline reports may indicate the Reid Vapor Pressure of the ...
How Long Does It Take for Gas to Go Bad? The length of time fuel will remain useable in your gas tank is dependent on the fuel type. Regular gasoline has a shelf life of three to six months, premium or high-octane fuel should last close to nine months, while diesel can last up to...
Reforming is a common refining technology used primarily to upgrade low-value naphtha into higher-value gasoline by raising its octane. Reforming can also be used to produce aromatics instead of gasoline. Refiners can maximize value from aromatics by increasing reformer severity, ...
In case, the car battery is disconnected and the light comes right back on, this may show an active problem and should be addressed and fixed. Turn The Ignition On And Off It’s a repeat of the previous technique without disconnecting the battery. You just have toput the key into the ...
Then the piston moves back up to compress this fuel/air mixture. Compression makes the explosion more powerful. (Part 2 of the animation) When the piston reaches the top of its stroke, the spark plug emits a spark to ignite the gasoline. The gasoline charge in the cylinder explodes, drivin...
