Evaluation of Succinimides by LTD Engine Test

Three succinimides having different amino groups were evaluated by CRC-LTD engine test. The succinimide which has more basic nitrogens shows better test results. Test results were obtained in the following order, with succinimide-A giving the best results;succinimide-A>succinimide-B>succinimide-C.These results are consistent with the mechanism of additive action previously proposed by the author.
