Abstract: A fuel and gas mixing structure for an engine is provided. This mixing structure includes a body configured to be positioned between a fuel injector and a cylinder of an engine. The body defines an interior volume that is configured to receive gas from outside the body and to receive one or more streams of fuel from the fuel injector in the interior volume. The body also defines one or more mixture conduits configured to conduct plumes of the fuel and gas, while mixing, from the interior volume to one or more exit ports and therethrough to the cylinder.

Abstract: A method for use with an internal combustion engine having both donor and non-donor cylinder groups includes: injecting a fuel in one, or both, of the groups; injecting a second fuel in both groups at a first substitution rate; recirculating an exhaust emission from the donor cylinder group to both groups; combusting a mixture of air, the first fuel, the second fuel and the exhaust emission in both cylinder groups; and lowering the substitution rate of the second fuel in one, or both, of the cylinder groups. Other methods of controlling an engine and a system are also disclosed.

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.

Abstract: A control system for an engine includes one or more processors configured to determine when a change in one or more of oxygen or fuel supplied to an engine. The one or more processors also are configured to, responsive to determining the change in oxygen and/or fuel supplied to an engine, direct one or more fuel injectors of the engine to begin injecting fuel into one or more cylinders of the engine during both a first fuel injection and a second fuel injection during each cycle of a multi-stroke engine cycle of the one or more cylinders.

Abstract: Methods of operating an internal combustion engine that has two exhaust paths, the first path having an aftertreatment system. One method includes: operating the engine at idle; directing the exhaust flow through the first exhaust path; detecting an exhaust temperature below a predetermined temperature and/or operation of the engine at idle; and diverting all, or some, of the exhaust flow through the second exhaust path, based on the detecting. Another method includes detecting an engine condition that is indicative of an oil accumulation above a threshold and diverting the exhaust flow through the second exhaust path, based on detecting this engine condition. An exhaust subsystem that includes a controller that employs these methods is disclosed.
