Abstract: A system according to the principles of the present disclosure includes a fuel injector cleaning module and a fuel control module. The fuel injector cleaning module generates an instruction to clean a fuel injector of an engine based on engine operating conditions. The fuel control module, in response to the injector clean instruction, controls the fuel injector to perform N fuel injections for each combustion event in a cylinder of the engine and, during each of the N fuel injections, deactivates the fuel injector before the fuel injector fully opens. N is an integer greater than one.

Abstract: A system according to the present disclosure includes a fuel control module and at least one of a desired air per cylinder (APC) module and a predicted manifold absolute pressure (MAP) module. The desired APC module determines a desired amount of airflow to each cylinder of an engine. The predicted MAP module predicts a pressure within an intake manifold of the engine at a future time. The fuel control module selectively adjusts a fuel injection parameter of the engine based on at least one of: a change in the desired air per cylinder from a first time to a second time; and a change in the predicted manifold pressure from the first time to the second time.

Abstract: A system according to the principles of the present disclosure includes a communication module and a control module. The communication module transmits a first wireless signal indicating a request from a user of a vehicle to adjust operation of a powertrain in the vehicle, a display in the vehicle, and/or a noise actuator in the vehicle. The communication module receives a second wireless signal enabling operation of the powertrain, the display, and/or the noise actuator to be adjusted according to the request. The control module controls the powertrain, the display, and/or the noise actuator based on a first set of values for a control parameter before the second wireless signal is received. The control module controls the powertrain, the display, and/or the noise actuator based on a second set of values for the control parameter after the second wireless signal is received.

Abstract: A light-weight, gas chargeable, self-contained, shock absorber piston assembly which can be retrofitted to various landing gear. The invention permits taxi and take off in either a "normal" or "rough" runway configuration, followed by subsequent landing, taxi and take off again in either mode. The reconfiguration of the gear for these modes is at the option of the aircrew. There is no need to resupply the landing gear with gas from an external source until completion of a number of system actuations.
