Hydrogen engine control system

This suppresses both the occurrence of torque shock and the increase in NOx emissions when switching between stoichiometric and lean combustion. [Solution] The processing circuit 22 of the electronic control unit 21 that controls the hydrogen engine 10 is configured to inject the amount of fuel necessary to generate engine torque according to the required torque as the main injection during the air amount adjustment period for switching between stoichiometric combustion and lean combustion, and to inject the amount of fuel as the post injection such that the total injection amount of the main injection and the post injection is the amount obtained by dividing the actual air amount by the stoichiometric air-fuel ratio.

Injection pen

The utility model relates to an injection pen. The injection pen comprises a shell, a knob, a connecting pipe sleeve, a first elastic piece, a push rod, a retaining assembly and a medicine bin, the knob is rotatably connected to the shell; the connecting pipe sleeve is positioned between the shell and the push rod; the push rod is connected with the retaining assembly; the first elastic piece is connected to the connecting pipe sleeve; a tooth structure is arranged on the inner wall of the shell; a connecting part and a side arm are respectively arranged at two opposite ends of the connecting pipe sleeve; in a dose setting stage, the knob is connected with the connecting part to drive the connecting pipe sleeve to rotate synchronously, so that the first elastic piece rotates to store energy; the side arm is kept in contact with the tooth structure so as to prevent the first elastic piece from releasing energy; after injection is triggered, the connecting part is separated from the rotary knob, the side arm is separated from the tooth structure, and the connecting pipe sleeve moves to the position connected with the maintaining assembly, so that energy of the first elastic piece is released, and medicine in the medicine bin is pushed. The injection pen is compact in overall structure, and the reliability of the injection pen can be improved.

Transient response strategy for hydrogen fueled internal combustion engines

Systems, methods, and apparatuses are disclosed that determine a post injection fueling condition in response to one or more engine operating parameters. In response to the post injection fueling condition being present, one of a transient response mode or a thermal management mode is selected in order to determine a post injection fueling amount from a transient response fueling table or a thermal management fueling table. The transient response mode is selected in response to the lambda amount being less than a lambda threshold, and the thermal management mode is selected in response to the lambda amount being less than the lambda threshold and an aftertreatment temperature being less than a temperature threshold.

An automated injection device suitable for pre-filled syringes

This invention discloses an automatic injection device suitable for pre-filled syringes, comprising a cap, outer shell, inner shell, inner tube, rotating support, nozzle, needle buckle, piston rod, syringe, first spring, and second spring. The medication is pre-installed in the automatic injection device according to the type and volume of the drug to be injected. In emergencies and harsh environments, it enables self-rescue and mutual rescue for individuals without medical expertise. Larger doses of medication can be administered intramuscularly with a single-person, one-button operation. This invention is not only highly adaptable to various environments (resistant to bumps and contamination), but also has a self-locking function to prevent leakage of the syringe due to improper operation. Furthermore, the automatic injection device is truly unusable after a single injection, avoiding secondary contamination and accidental injury.

Dual chamber post injection air guided self-locking control and water-air mixing post injection device

The present application relates to the technical field of micro-recoil launching, and particularly relates to a double-chamber rear ejection passage air guide self-locking control and water-gas mixed rear ejection device. The device comprises a launching cylinder, a control body, a piston, a return spring, a lock pin, a control spring, a rear ejection pipeline, a nozzle clamp, an air guide pipe, a valve, a valve spring and a double-chamber structure. The present application adopts the method of air guide control lock pin self-locking, and the lock pin is moved by high-pressure gas to serve as a piston starting switch, and the lock pin is locked by the piston after being moved to the position, so that the piston cannot be returned during the continuous rear ejection process of the gas. At the same time, a water tank is arranged outside the rear ejection passage, and the water tank is in full contact with the contraction section of the rear ejection passage through a water guide hole to generate a water-gas mixture with high density for rear ejection, so that the rear ejection impulse of the launcher is greatly improved, and the purpose of greatly reducing the recoil force to realize micro-recoil launching is achieved. The present application can solve the problems that the rear ejection passage is difficult to be continuously conducted and the rear ejection impulse of the gas is small in the current double-chamber launching method.
