| Abstract: | According to various aspects, an additive for a hydrocarbon-based fuel has a formula (I), in which R1, R2, and R3 are each independently selected from —H, —CH3, or —CH2CH3, and at least one of R1, R2, or R3 is not —H. The additive improves an autoignition reactivity of the hydrocarbon-based fuel. The additive can be present in the fuel composition including the additive and the hydrocarbon-based fuel in an amount of 0.1% by volume to 5% by volume. The hydrocarbon-based fuel can comprise gasoline or diesel. |
