Abstract: A method of delivering fuel to an engine during operation of the engine, that includes, sensing the speed of sound in the fuel, determining a density or property of the fuel, and based on that density or fuel property adjusting the flow rate of the fuel. Further, an established fuel profile or determined energy density value can also be used to adjust the flow rate of the fuel.

Abstract: Fuel injector wear compensation methodologies for use with internal combustion engines that alter the injection schedule over the life of the fuel injector(s) by using methods that conduct a primary injection of fuel in the engine (primary fuel event), per an injection schedule within an engine cycle; compare a measured engine parameter(s) to a reference value(s); and then alter the injection schedule applied to the engine, based on the comparing. Another method comprises: during injection events, inject a first fuel in a combustion chamber of the engine; measure an engine parameter(s) of the engine during operation; compare the engine parameter(s) to a reference value(s); add a post injection event of a second fuel during the injection events, based on the comparison. The methods can be applied with single or dual fuels.

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.
