    Abstract: Embodiments for a cooling arrangement are provided. In one example, a cooling arrangement comprises a low-temperature circuit for charge-air cooling of a turbocharger of an internal combustion engine, an engine cooling circuit for cooling the internal combustion engine, and a charge-air cooler arranged in the low-temperature circuit and connected in a fluid-conducting manner on a coolant inlet side, via a first valve device, to the low-temperature circuit and to the engine cooling circuit, and on a coolant outlet side, via a second valve device, to the low-temperature circuit and to the engine cooling circuit. In this way, coolant from the engine may heat the charge-air cooler under certain conditions.

  • Patent number: 8245499
    Abstract: The invention relates to a control method for increasing the exhaust gas temperature of an internal combustion engine by increasing the exhaust back-pressure, yet maintaining an exhaust gas recirculation rate. Further, the fuel injection quantity of a main injection into the engine is increased. In this way, it is possible to increase the temperature of the exhaust gas and avoid engine oil dilution due to retarded post-injections.

  • Publication number: 20120186564
    Abstract: Embodiments for determining oxygen concentration using an oxygen sensor are provided. In one example, a method for determining oxygen concentration O2 in a gas flow of an internal combustion engine which is equipped with an engine controller and an oxygen sensor comprises determining the oxygen concentration O2,sens of the gas flow in a ceramic measurement cell of the sensor by current ISens which is detected by measurement and which flows when a constant voltage USens is applied and maintained, and correcting the oxygen concentration based on a pressure pSens at the measurement cell. In this way, the measured oxygen concentration may be corrected based on the pressure of the air at the sensor.

  • Patent number: 8046153
    Abstract: A fuel compensation factor (FCF) is determined to account for the amount of oxygenated fuel blended in diesel fuel. In one embodiment, the FCF is based on an expected exhaust gas oxygen concentration compared to an actual exhaust gas oxygen concentration. The FCF is used to estimate an amount of oxygenated fuel in the blend. Such estimate can be used to adjust the exhaust temperature model, which is used at least in determining the temperature in aftertreatment devices, the fuel dilution model which affects oil change recommendations, and the diesel particulate filter loading model which affects regenerations. Biodiesels are more prone to waxing at lower temperatures. The estimated amount of biodiesel and the temperature in the injection system are used to prevent and/or delay starting when it is predicted that too much wax exists in the fuel system.

  • Patent number: 8036812
    Abstract: A system and method are disclosed for controlling an internal combustion engine in which actual concentration of combusted gas in the intake is compared with desired concentration of combusted gas in the intake. When a difference is detected, at least one of start of injection timing and quantity of fuel injected is adjusted in accordance with the difference. The actual concentration of combusted gas in the intake is estimated based on engine sensors such as an oxygen sensor coupled to an engine intake. The adjustment of injection timing and/or quantity of fuel is performed, according to some embodiments, during a transition between a low temperature combustion mode and a standard diesel combustion mode.

  • Publication number: 20110162628
    Abstract: To partially supplant the use of fossil fuels in diesel engines, oxygen-containing fuels, such as biodiesels, are proposed as blending agents in diesel fuel. Engine calibration coefficients to control EGR rate, timings and quantities of fuel injection pulses, turbocharger boost, etc, can be determined to compensate for the lower energy content of such oxygenate blends compared to diesel fuels. According to an embodiment of the disclosure, the fuel quantity of each of multiple injection pulses is increased proportionally to compensate for the impact of oxygenates. An adjustment in the fuel injection quantity is performed in response to a new tank of fuel and the adjustment is applied for that tank of fuel. A fuel compensation factor (FCF) can be determined based on the actual amount of fuel injected compared to the expected amount of diesel fuel at the present operating condition.

  • Publication number: 20090151333
    Abstract: The invention relates to a control method for increasing the exhaust gas temperature of an internal combustion engine, which has at least one exhaust gas aftertreatment device in its exhaust tract, and which has an exhaust gas recirculation system, to which a regulating system is assigned. In order to increase the temperature of the exhaust gas and avoid engine oil dilution due to retarded post-injections, the regulating system increases the exhaust gas back-pressure while maintaining an exhaust gas recirculation rate, and increases a fuel injection quantity into the combustion chamber during the main injection.
