The use permits substantial-output engines to generate much more energy with the compressed air-fuel combination. Large-compression engines can have to have superior-octane fuel to make sure the combination doesn’t ignite early. This is usually often called engine knocking or finish-gasoline knock. Knocking is often minimized by expanding the gasoline's resistance https://damienukleq.wikipresses.com/4194344/an_unbiased_view_of_gasoline_chemical_formula
