摘要： This fuel property estimation device is used in an internal combustion engine that uses a mixed fuel of three kinds of fuel and includes a first sensor that outputs a signal responsive to a physical property of the fuel in a fuel route and a second sensor outputs a signal responsive to an oxygen concentration of exhaust gas. This device measures a physical property value of the mixed fuel based on a first sensor signal, and calculates an air-fuel ratio value at stoichiometric combustion state using feedback of a second sensor signal. This device estimates a composition ratio of the mixed fuel based on the measured physical property value and the calculated air-fuel ratio value by referring to a relationship between the composition ratio of the mixed fuel and the physical property value and a relationship between the composition ratio of the mixed fuel and a theoretical air-fuel ratio value.

摘要： In order to estimate the cetane number of a fuel, fuel injection is executed by controlling the driving of a fuel injection valve by a prescribed amount. The amount of change in the rotation of a diesel engine generated in response to the fuel injection is detected, and the cetane number of the fuel is estimated on the basis of this amount of change in the rotation. The actual amount of fuel injected from the fuel injection valve is detected, and when the difference between the amount actually detected and the prescribed amount is equal to or greater than a threshold value, the execution of the fuel cetane number estimation process is restricted.

摘要： A method to control a gas engine system is disclosed, whereby the engine can be operated with an air-fuel-ratio controlled with high precision, even in using a low calorific fuel-gas that is prone to vary in calorific value; the engine system includes: a first gas line toward each cylinder via a first gas valve from a gas supply source line, the first gas valve regulating flow rates of the fuel-gas through a gas compressor on the line; a second gas line toward suction air, the line being branched from the gas supply source line and the line being provided with a gas air mixer and a second gas valve on the line. In the case when the fuel-gas is of a low calorific value or where the output of the engine is high, a part of the fuel-gas is supplied to the engine through the first and second lines. The mixer forms a mixture of a prescribed mixing ratio that is leaner than a lower limit of flammability of the fuel-gas, while the remaining fuel-gas through the first line is supplied to the mixture just before each cylinder so that a final prescribed air fuel ratio is formed. In the case when the calorific value of the fuel-gas is high, or of high engine output, the whole fuel-gas can be supplied only through the first gas line.

摘要： A method and a system for detection of torque deviations of an engine (101) in a vehicle (100). A measurement (201) is made of actual measured values Dact related to a behavior of at least one parameter which is related to an actual torque Meng_act delivered by the engine (101). This actual torque Meng_act is delivered here by the engine (101) in consequence of a torque Meng_req demanded from the engine (101). A comparison (202) is then made of the actual measured values Dact which are related to the behavior of the at least one parameter with previously determined measured values Dref of correspondingly at least one respective parameter related to the actual torque Meng_act. The previously determined measured values Dref will here have been determined during normal operation of the vehicle (100). Detection is then made of whether the actual measured actual torque Meng_act deviates from the demanded torque Mengj-eq. The detection is based here on the comparison of the actual measured values Dact with the previously determined measured values Dref.

摘要： An object is to provide a method and an apparatus which can be implemented with a simplified and inexpensive configuration without causing a misfire in a combustion state. In a fuel-Cetane-number estimation method of the present invention, a map which specifies a relationship between the Cetane number and a control parameter at which NOx concentration of exhaust gas reaches a predetermined value is prepared in advance. Then, the control parameter is controlled variably to detect transition of the NOx concentration of the exhaust gas of the internal combustion engine, and thereby the control parameter of the internal combustion engine at which the NOx concentration has reached the predetermined value is obtained, and the Cetane number which corresponds to the obtained control parameter is estimated on the basis of the map.
