Additives for improving autoignition reactivity of hydrocarbon-based fuels
View Patent ↗According to various aspects, an additive for a hydrocarbon-based fuel has a formula (I), in which R 1 , R 2 , and R 3 are each independently selected from —H, —CH 3 , or —CH 2 CH 3 , and at least one of R 1 , R 2 , or R 3 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.
