| 20110093181 | METHOD FOR BIODIESEL BLENDING DETECTION BASED ON INTERNAL MEAN EFFECTIVE PRESSURE EVALUATION - A method for biodiesel blending detection in a internal combustion engine includes, but is not limited to a first evaluation of the internal mean effective pressure (IMEP) by means of measurements provided by a first sensor whose output is representative of the actual IMEP value, a second evaluation of the internal mean effective pressure (IMEP) performed measuring fuel conversion efficiency (FCE), injected fuel quantity (Q | 04-21-2011 |
| 20110093185 | METHOD FOR OPERATING AN INTERNAL COMBUSTION ENGINE SYSTEM - A method for operating an internal combustion engine system includes, but is not limited to a combustion engine having intake manifold and exhaust manifold, a first EGR route for conveying exhaust gas from exhaust manifold to intake manifold, a second EGR route configured for conveying to the intake manifold exhaust gas having lower temperature than that conveyed through the first EGR route, and regulator for regulating the flow rate of exhaust gas through the first and the second EGR route. The method includes, but is not limited to determining a first setpoint value for the total amount of exhaust gas requested into the intake manifold, determining a second setpoint value for a parameter representative of the relationship between the total amount of exhaust gas requested into the intake manifold, the amount of exhaust gas from the first EGR route and from the second EGR route, applying said first and second set-point values to a control routine for adjusting the regulating means accordingly, determining a third setpoint value for the temperature in the intake manifold, determining the actual temperature in the intake manifold, calculating the error between said actual temperature and the third setpoint value, and using said error for generating a correction index to be applied to the second setpoint value, in order to minimize said error. | 04-21-2011 |
| 20110114066 | DEVICE AND METHOD FOR COMPRESSOR AND CHARGE AIR COOLER PROTECTION IN AN INTERNAL COMBUSTION ENGINE - A device is provided for compressor and charge air cooler protection in an internal combustion engine, such as a Diesel engine. The engine having an intake manifold and an exhaust manifold, first and second EGR routes, a charge air cooler, a turbocharger having a compressor and a turbine. A regulator is also provided for regulating the flow rate of exhaust gas and the splitting of exhaust gas between the first and second EGR route. A temperature sensor is also provided for sensing output temperature of gas at the outlet of said compressor. A method and computer readable medium embodying a computer program product are also provided that have a first phase of monitoring a parameter representative of the gas temperature at the output of the compressor and a second phase in which an activity involving engine components operation is performed. The activity is performed using temperature information determined in the monitoring phase. | 05-19-2011 |
| 20110125383 | METHOD FOR BIODIESEL BLENDING DETECTION BASED ON RELATIVE AIR-TO-FUEL RATIO ESTIMATION - A method is provided for biodiesel blending detection in an internal combustion engine that includes, but is not limited to a first evaluation of the relative air-to-fuel ratio (RAFR) by means of a first sensor whose output whose output is representative of the actual RAFR value, in order to use such first evaluation as a reference value, a second evaluation of the relative air-to-fuel ratio (RAFR) performed measuring mass air flow (MAF), injected fuel quantity (Q | 05-26-2011 |
| 20110146272 | DIESEL ENGINE FOR A MOTOR VEHICLE - A diesel engine is provided for a motor vehicle. The engine includes, but is not limited to a long route exhaust gas recirculating (LR-EGR) system, in which a Lean NO | 06-23-2011 |
| 20110153179 | METHOD FOR OPERATING A DIESEL ENGINE SYSTEM - A method is provided for operating a Diesel engine system. The diesel engine system includes, but is not limited to a Diesel engine, an intake line for feeding fresh induction air into the Diesel engine, an exhaust line for discharging exhaust gas from the Diesel engine, a Diesel Particulate Filter DPF located in the exhaust line, and an Exhaust Gas Recirculation EGR system for routing back exhaust gas into the Diesel engine. The EGR system includes, but is not limited to a long EGR route LRE that gets exhaust gas from the exhaust line downstream the DPF. The method includes, but is not limited to setting a soot threshold (Sth) for the amount of soot flowing into the LRE, determining the actual amount of soot (Saa) flowing into the LRE, and activating a LRE protection routine, if the actual amount of soot (Saa) exceeds the soot threshold (Sth). | 06-23-2011 |
