摘要： A first energy control unit has a pilot controller with an applied setpoint energy and outputs a pilot control signal, and a regulator outputting a regulator signal as a function of the setpoint energy and an actual energy of the piezo actuator. The energy control unit creates a control signal representative for a current threshold of a charge current, depending on the pilot control and regulator signals. Furthermore, there is a second energy control unit for another setpoint energy and another control signal. A power output stage sets a charge current for the piezo actuator as a function of the predetermined control signal and performs this for the predetermined time. A scheduling unit predetermines, for setting the setpoint energy, the control signal and the time to the power output stage, and for setting the another setpoint energy, the another control signal and the time to the another power output stage.

摘要： The invention relates to a system and method for use in a homogeneous charge compression ignition (HCCI) combustion engine that is preferably equipped with an exhaust gas recirculation device. This system and method enable an improved adjustment of the temperature level inside the combustion chamber. In addition to adjusting the temperature by using the exhaust gas recirculation device, an influencing of the temperature, which is independent thereof, ensues based on the compression of the induced fresh air by the exhaust gas turbocharger. An increase in temperature is maintained even after the compressed air is expanded on a throttle valve, and this increase in temperature can, in the end, be used for influencing the energy content inside the combustion chamber.

摘要： The isentropic exponent (χ) and the constant (k) in the equation p·Vχ=k for processes before and after fuel combustion in the cylinder are determined on the basis of the signals from a cylinder pressure sensor and from a crankshaft sensor. Cylinder pressures (p) before and after fuel combustion can be determined through the equation with the corresponding isentropic exponents (χ) and corresponding constants. During fuel combustion, cylinder pressure (p) is sensed by the cylinder pressure sensor. The ratio between the fuel mass burned in the cylinder of the internal combustion engine and the fuel mass (MBR) supplied to the cylinder is determined on the basis of the above-mentioned variables. The process has the advantage of reducing the computation outlay necessary to determine the ratio between the fuel mass burned in the cylinder of the internal combustion engine and the fuel mass (MBR) supplied to the cylinder.
摘要翻译：基于来自气缸压力传感器和来自气缸压力传感器的信号来确定在气缸内燃料燃烧之前和之后的过程的等式pV 中的等熵指数（chi）和常数（k）从曲轴传感器。燃料燃烧前后的气缸压力（p）可以通过具有相应等熵指数（chi）和相应常数的方程来确定。在燃料燃烧期间，气缸压力（p）由气缸压力传感器感测。基于上述变量来确定在内燃机的气缸中燃烧的燃料质量与供给到气缸的燃料质量（MBR）之间的比率。该方法的优点是减少了确定内燃机的气缸燃烧的燃料量与提供给气缸的燃料质量（MBR）之间的比例所需的计算量。
