摘要： A process and a system for preventing pre-ignition in an internal combustion engine (ICE). The process includes providing an ICE that has a combustion chamber and an exhaust. Also provided is a total hydro-carbon (THC) sensor in communication with the combustion chamber. The THC sensor senses a THC level of the combusted gas for a given combustion cycle i (THCi) of the ICE. In the event that THCi is greater than a reference THC level (THCref), a pre-ignition countermeasure prior to an immediate subsequent combustion cycle i+1 is executed. Furthermore, the executed pre-ignition countermeasure prevents pre-ignition from occurring in the immediate subsequent combustion cycle i+1 of the ICE.

摘要： A method of controlling a concentration of hydrocarbons in exhaust gas from an internal combustion engine includes sensing an oxygen percentage of the flow of exhaust gas from the internal combustion engine and determining a concentration of hydrocarbons in the flow of exhaust gas. An engine control module may then adjust the sensed oxygen percentage of the exhaust gas based on the determined concentration of hydrocarbons in the flow of exhaust gas to define a corrected oxygen percentage. The control module may then control at least one of a hydrocarbon injection rate for in-cylinder combustion of the internal combustion engine, and a hydrocarbon injection rate for a post combustion exhaust gas treatment process, based on the corrected oxygen percentage, to control the concentration of hydrocarbons in the exhaust gas.

摘要： A method for diagnosing the degree of deterioration of a catalyst disposed in an exhaust path of an internal combustion engine and oxidizes or adsorbs a target gas, including at least one of a hydrocarbon gas and a carbon monoxide gas in an exhaust gas from the internal combustion engine, is adapted to determine whether deterioration exceeding an acceptable level of a catalyst occurs or not by comparing the concentration of a target gas detected downstream from the catalyst in the exhaust path when a diagnosis-gas atmosphere containing a target gas higher in concentration than a target gas during a steady-operation state of the internal combustion engine is intentionally produced and introduced into the catalyst with a threshold value corresponding to the temperature of a catalyst at the timing which the diagnosis-gas atmosphere is introduced.

摘要： Methods and systems are provided for estimating a fuel concentration in engine oil in an engine crankcase. In one example, an engine controller may adjust engine operation such as EGR flow and engine fueling based on the estimated fuel concentration in engine oil. The fuel concentration may be based on an output of an intake oxygen sensor when purge and EGR flow are disabled, engine oil temperature, and fuel composition.

摘要： A method for reducing the pollutant emissions in the exhaust gas in a start/catalytic converter heating phase of an internal combustion engine featuring externally supplied ignition and having at least one catalytic converter in an exhaust gas tract of the internal combustion engine, and for adapting a catalytic converter heating strategy to suitable state variables of the internal combustion engine and the catalytic converter as well as to the fuel quantity, the aging state and ambient conditions. The internal combustion engine is operated in a first phase of the start/catalytic converter heating phase using a lean air-fuel mixture in a range between a lambda value of 1.05 and at a lean misfire limit of the internal combustion engine that lies at a higher lambda value, and/or in a second phase of the start/catalytic converter heating phase, initially using a rich air-fuel mixture.

摘要： An exhaust-gas sensor signal (vls_down) of an exhaust-gas sensor that is disposed in an exhaust gas train downstream of at least one first catalytic converter volume (V1) and upstream of at least one second catalytic converter volume (V2) is acquired. An estimated value of an intermediate emission for a position of the exhaust-gas sensor is determined in dependence upon the exhaust-gas sensor signal (vls_down). An estimated value of an emission downstream of the at least one second catalytic converter volume (V2) is determined in dependence upon the estimated value of the intermediate emission and in dependence upon at least one predefined correction characteristic (fac_cor_ufc) or at least one predefined correction characteristics map for correcting the estimated value of the intermediate emission with regard to an influence of the at least one second catalytic converter volume (V2) upon the emission of the at least one exhaust gas component.
