The first nozzle includes an ablative shell, a syntactic foam support disposed between the ablative shell and the second nozzle, and an ignition system disposed at least partially within the syntactic foam support. For example, the ignition system is operable to generate a controlled-energy deflagration pressure wave that fragments the first nozzle but not the second nozzle. |

Attitude control system
An attitude control system for a guided missile includes a gas generator, an accumulator coupled to the gas generator, and a valve positioned between the gas generator and the accumulator. The gas generator contains propellant that burns to provide hot gas to pressurize the accumulator. The valve is opened to recharge the accumulator with hot gas and closed when it is full. A vent valve can be included to extinguish the propellant in the gas generator. The accumulator can be coupled to thrusters that use the stored hot gas to adjust the attitude of the guided missile. |

Control system for engine
A control system for an engine is provided, which includes an engine body formed with a cylinder, a NOx catalyst, an oxidation catalyst, a PM filter, a fuel injector configured to perform a main injection and a post injection, and a controller configured to execute a DeNOx control in which the fuel injector is controlled to perform the main and post injections so that an air-fuel ratio of exhaust gas is brought close to the stoichiometric air-fuel ratio or becomes rich and fuel supplied into the cylinder by the post injection combusts therein, and a filter regenerating control in which the fuel injector is controlled to perform the main and post injections so that the air-fuel ratio becomes lean and the fuel supplied into the cylinder by the post injection causes no combustion therein, the controller executing the DeNOx control and the filter regenerating control consecutively in this order. |

High-pressure pump and fuel-supply system using same
A high-pressure pump includes: a low-pressure chamber, into which low-pressure fuel discharged from a low-pressure pump flows; a pressurizing chamber, which pressurizes the low-low-pressure fuel; and a leak chamber, into which leaked fuel from the pressurizing chamber flows. The leaked fuel of the leak chamber is suctioned into and is pressurized in the pressurizing chamber together with the low-pressure fuel of the low-pressure chamber, so that the leaked fuel is discharged to an outside of the high-pressure pump as high-pressure fuel. Furthermore, a suction check valve, which is placed between the low-pressure chamber and the leak chamber, limits backflow of the leaked fuel of the leak chamber to the low-pressure chamber when the high-pressure pump does not supply the high-pressure fuel. |

Injector driving device
An injector driving device includes a control circuit of a booster circuit that charges a capacitor by repeatedly switching a booster switch ON/OFF during a voltage boost control to cause a reverse voltage in a coil, and stops the voltage boost control upon determining that a capacitor voltage has reached a corrected target value. The control circuit detects a peak value of the capacitor voltage during an OFF period of the boost switch. The control circuit also detects a capacitor voltage as an ON value during the subsequent ON period of the booster switch. A difference between the peak voltage and the ON value of the capacitor is calculated, and a post-correction target value is set by adding the difference to a reference value of a target value. |

Fuel injection controller and fuel injection system
A fuel injection controller includes an increase control portion applying the boost voltage to the coil to increase a coil current to a first target value, and a constant current control portion applying a voltage to the coil to hold the coil current to a second target value. A threshold is an energization time period that is necessary to reach a boundary point between a seat throttle area of a property line and an injection-port throttle area of the property line from an energization start time point. An initial-current applied time period is from the energization start time point that the boost voltage starts to be applied to the coil to a time point that the coil current is decreased to the second target value. The increase control portion controls the coil current such that the initial-current applied time period is less than the threshold. |

Method for determining and applying an engine misfire threshold
Systems and methods for operating an engine operated by a controller that has a capacity to determine whether or not misfire occurs in the engine are presented. In one example, an operating region of the engine is broken into a plurality of zones and a misfire threshold level is dynamically provided for each of the plurality of zones based on slowly updated zone-level statistical parameters and quickly updated buffer-level parameters. The real-time dynamic misfire thresholds provide a basis for determining misfire within the engine. |

Control device for engine
A control device for controlling an engine based on an operating state of a vehicle is provided. The control device includes a processor configured to execute a basic target torque determining module for determining a basic target torque based on an operating state of the vehicle, a torque reduction amount determining module for determining a torque reduction amount based on a part of the operating state of the vehicle, a final target torque determining module for determining a final target torque based on the basic target torque and the torque reduction amount, an engine controlling module for controlling the engine to output the final target torque, and a torque change smoothing module for smoothing a chronological change of the final target torque corresponding to the torque reduction amount at a smaller smoothing degree than that of the chronological change of the final target torque corresponding to the basic target torque. |

Methods and systems for aftertreatment preheating
Systems and methods are provided for preheating emissions control devices prior to engine startup using a heating element and a flow control device operable to provide a fluid flow, such as a compressor or a turbine. One exemplary method of heating an emissions control component prior to engine startup involves opening or otherwise operating a valve to provide a path for fluid flow to the emissions control component, operating a flow control device to provide the fluid flow through the path, and activating a heating element upstream of the emissions control component to heat the fluid flow to the emissions control component. |
