摘要： A system for precisely controlling gas under high pressure produces an initial gas pressure in a pressure chamber while applying a predetermined amount of power to a heating element located in the pressure chamber and then applies a computed change of power to produce an average gas temperature increase or decrease in the pressure chamber and thereby rapidly produce an increase or decrease in gas pressure with resolution limited by the resolution of measurement of gas pressure in the pressure chamber and the application of the computed change of power. The described invention is particularly advantageous at gas pressure above roughly 1000 pounds per square inch.

摘要： The invention relates to a pressure regulation method for an internal combustion engine (1) having an accumulator injection system. According to said method, a first actual rail pressure is determined via a first filter from the measured rail pressure (pCR), a first deviation is calculated by comparing the desired/actual rail pressure, and a volume flow is determined as the regulating variable via a high-pressure regulator from the first deviation. According to the invention, a second actual rail pressure is determined from the measured rail pressure (pCR) via a second filter and said second actual pressure is made the reference value for calculating the regulator portions of the high-pressure regulator.

摘要： A pressure for a chamber is regulated by controlling either the exhaust pressure at the exhaust side of a first vacuum pump or the internal pressure at a compression stage of the first vacuum pump, where the first vacuum pump is directly communicating with the chamber. The pressure of the chamber can be regulated by combinations of the following: controlling the variable rotational frequency of a roots vacuum pump, a pre-vacuum pump, or a high compression pump; controlling a control valve between a pre-vacuum pump and the first vacuum pump; controlling a control valve for injecting gas into the exhaust side of the first vacuum pump or into the compression stage of the first vacuum pump; and controlling a control valve or control valves for bypassing the first vacuum pump or a compression stage or compression stages of the first vacuum pump. To regulate the pressure in the chamber, several types of control rules can be used, including: a PID control rule, a gain scheduler, and a threshold comparison control rude.
