The surface cooler assembly also includes at least one support bracket comprising bracket hook rails extending circumferentially the length of the support bracket and including axially extending and radially extending portions. The support bracket and surface cooler are contoured in a circumferential direction. Each of the surface cooler hook rails contacts a bracket hook rail. |

Waste heat recovery system with low temperature heat exchanger
Systems and methods are disclosed to recover waste heat from an engine fluid with a heat exchanger subsystem that includes a heat exchanger. The heat exchanger subsystem is thermally coupled to a working fluid and the engine fluid, so the waste heat from the engine fluid is transferred to the working fluid. The engine fluid is bypassed from the heat exchanger in response to a heat exchanger bypass condition. |

Preventing overstroke of free-piston stirling engine from loss of load
A method for limiting the amplitude of reciprocation of a piston reciprocating in a cylinder of a free-piston Stirling engine. The method is the combination of both at least partially covering the heat rejecter cylinder port by the piston sidewall during a peak part of the inward reciprocation of the piston and at least partially covering the heat rejecter cylinder port by the displacer sidewall during a peak part of the outward reciprocation of the displacer. The piston and the displacer, at times during their reciprocation, fully cover the effective heat rejecter cylinder port when the piston amplitude of reciprocation is large and approaches the physical limit of the amplitude of reciprocation in order to avoid internal collisions by a reciprocating component. |

Work vehicle
There are provided an intake pressure detecting means for detecting an intake pressure on more downstream side than a throttle valve in an intake passage to an engine, a rotational speed detecting means for detecting a rotational speed of an engine, an engine controlling means for controlling the engine to arrive at a target air-fuel ratio corresponding to the detected intake pressure and the detected engine rotational speed and an abnormality treating means for executing an engine stopping treatment to stop the engine if an intake pressure higher than a set pressure has been detected and an engine rotational speed higher than a set rotational speed has been detected, when an opening degree state detecting means detects that the throttle valve is under a fully closed or substantially fully closed state. |

Natural gas fuel reformer control for lean burn gas engines
A reformer system may include a reformer device having a fuel inlet, an air inlet and a gas outlet, a first valve set coupled to the fuel inlet and configured to selectively supply a reformer fuel flow from an engine fuel flow to the fuel inlet, a second valve set coupled to the air inlet and configured to selectively supply a reformer air flow from a compressor outlet air flow to the air inlet, and a controller in electrical communication with the first valve set and the second valve set. The controller may determine a target reformer fuel flow based on a target gas flow, determine a target reformer air flow based on the reformer fuel flow and a target air-to-fuel ratio, adjust the reformer fuel flow according to the target reformer fuel flow, and adjust the reformer air flow according to the target reformer air flow. |

Systems and methods for fuel-based thermal management
A fuel-based thermal management system may comprise a heat exchanger configured to thermally couple a fluid and a fuel. A controller may be configured to modulate a flow of the fluid to the heat exchanger. A tangible, non-transitory memory may be configured to communicate with the controller. The controller may determine a temperature of the fluid, estimate a dissolved oxygen concentration in the fuel using a first fuel temperature, a flight cycle time, and at least one of an altitude measurement or a ambient pressure measurement, and modulate the flow of the fluid to the heat exchanger based on the dissolved oxygen concentration. |

Prognostic health management control for adaptive operability recovery for turbine engines
The subject matter of the present disclosure is directed to a turbine engine having an adaptive prognostic health management control system that passively monitors stall margin reductions and applies corrective trims to a power management schedule of the engine to recover operability over time whilst maintaining a sufficient level of stall margin over the life cycle of the engine. The control system can adjust the power management schedule as needed to sustain a target stall margin, which allows for a more optimized and gradual performance to operability trade-off. |
