    摘要： A diesel internal combustion engine that is operated advantageously at least predominantly according to the diesel principle, with a multi-fuel adaptation unit that reacts to various fuels of different mixtures and adapts an operating mode of the internal combustion engine to these fuels, wherein the multi-fuel adaptation unit comprises at least the following elements: a fuel characterization, a combustion-chamber filling that can be adapted as a function of a characteristic fuel, external ignition that can be allocated to each cylinder of the internal combustion engine, at least one control device that implements a first control strategy in which, in a lower load range, external ignition is performed, and a second control strategy in which automatic ignition is performed in a load range that is higher relative to the lower load range, a combustion-point control that can be adapted automatically to the characterized fuel, and a conversion-rate control that can be adapted automatically to the characterized fuel.

    摘要： There is provided, in one aspect of the present description, an internal combustion engine system. In one example, the system comprises a controller configured to control an intake valve closing timing varying mechanism to vary a closing timing of the intake valve to regulate air charged in a combustion chamber in accordance with engine operating conditions and, in a first engine operating condition where a least volume of air is required to be charged into the combustion chamber, retard a closing timing of the intake valve to a most retarded crank angle which is after bottom dead center during a cylinder cycle and satisfies the following formulas: α≧−0.2685×ε02+10.723×ε0+15.815 and ε0≧11.0, where α is the most retarded crank angle and ε0 is a geometric compression ratio of the engine.

    摘要： To prevent inflow of condensed water to an exhaust gas recirculation (EGR) valve, an exhaust gas recirculation system includes a first gas passage, an exhaust gas recirculation valve connected to the first gas passage and selectively opening/closing the first gas passage, an exhaust gas passage disposed in the exhaust gas recirculation valve, and a second gas passage connecting the exhaust gas passage to an air-fuel mixture passage. The exhaust gas passage is tilted at an obtuse angle with respect to the second gas passage. The angle may be less than about 170°, and in some embodiments the angle is about 165°.
