    摘要： A four-cycle internal combustion engine has a permanent curtailed intake process, which allows the temperature and pressure of intake air to the combustion cylinders to be tightly controlled, and enables a very small combustion chamber so that a much higher compression ratio and pre-ignition compression pressure can be achieved without approaching the air/fuel mixture auto-ignition threshold. The maximum threshold of curtailed intake volume is determined to be 68% of engine cylinder volume to achieve a compression ratio CR of 22.1 or higher. Because this design can effectively regulate and set the maximum pre-ignition temperature of the fuel-air mixture, it can combust virtually any type of liquid hydrocarbon fuel without knocking. This four-cycle engine, due to its higher compression ratio, generates power equivalent to or greater than a standard four-cycle engine in a smaller and lighter engine and at a much higher efficiency.

    摘要： In a method for actuating an actuating member for adjusting a turbine flow cross section of a turbocharger of an internal combustion engine in a motor vehicle in the event of a change of the load of the internal combustion engine from a relatively low load value to a relatively high load value, the adjustment takes place at least at times by use of the closed-loop control of a scavenging gradient of the internal combustion engine. The method is characterized in that the turbine flow cross section, in the case of a spark-ignition engine as the internal combustion engine, is not fixedly held at a minimum turbine flow cross section between the change of the load and a beginning of an adjustment which is dependent on the scavenging gradient. A control unit is set up and controls the process of such a method.

    摘要： In a device for detecting faulty firing in an internal-combustion engine, a combustion-chamber pressure is measured at two crankshaft positions before and after each top dead center for each cylinder. At an ignition top dead center, a pressure differential must be greater than a first limiting value for there to be proper firing. At a charge-change top dead center, the pressure differential must be less than a second limiting value for the pressure measurement to be operating properly.

    摘要： An intake air quantity correcting device calculates an intake air quantity as a sensing target of an airflow meter (an intake air quantity sensor) based on an injection quantity sensing value sensed with a fuel pressure sensor (an injection quantity sensor) and an oxygen concentration sensing value sensed with an A/F sensor (an oxygen concentration sensor). The intake air quantity correcting device regards a difference between the intake air quantity calculation value calculated in this way and an intake air quantity sensing value sensed with the airflow meter as a sensing error of the airflow meter and corrects the intake air quantity sensing value of the airflow meter based on the sensing error.
