Abstract
A method of controlling an engine includes injecting a first fuel and a second fuel to each of a donor cylinder group and a non-donor cylinder group of the engine. The method also includes injecting a higher fraction of the first fuel into the donor cylinder group in comparison to the first fuel being injected into the non-donor cylinder group. Further, the method includes injecting a lower fraction of the second fuel into the donor cylinder group in comparison to the second fuel being injected into the non-donor cylinder group. Furthermore, the method includes recirculating an exhaust emission from the donor cylinder group to the non-donor cylinder group and the donor cylinder group and combusting a mixture of air, the first fuel, the second fuel and the exhaust emission from the donor cylinder group in both the donor cylinder group and the non-donor cylinder group.
