摘要： A method for operating an internal combustion engine that is supplied with lubricating oil via an oil circuit. A measurement value of the total base number and/or a measurement value of the oxidation of lubricating oil currently used in the oil circuit for the lubrication is detected. Dependent on the established measurement value of the total base number and/or dependent on the established measurement value of the oxidation an exchange oil quantity for the oil circuit is determined. Currently used lubricating oil to an extent corresponding to the exchange oil quantity is removed from the oil circuit and new lubricating oil to an extent corresponding to the exchange oil quantity is supplied to the oil circuit.

摘要： An intake adaption system for internal combustion engines of vehicles employing an aftermarket intake air assembly including high capacity intake ducting and a low resistance air filter. Intake air sensors provide intake air condition signals of filtered intake air to the engine. A CPU includes a routine for modifying the intake air condition signals of the filtered intake air to the ECM. Tables alter the appropriate sensor signal or signals to correct for the calibration and predictions made by the ECM based on the original equipment. A first table translates the intake air condition signals from the intake air sensors indicative of MAF into the engine to provide actual MAF into the engine. A second table generates a pressure offset responsive to MAF into the engine to provide the ECM with a lower pressure value than actual, avoiding a diagnostic trouble code.

摘要： The present invention is a system and method for adapting and modifying an existing mono-fuel delivery system for an internal combustion engine to run as a bi-fuel system by reusing and repurposing OEM components of the mono-fuel system. The bi-fuel system makes use of an integration plate that may be mounted to the system fuel filter in substantially the same location as the fuel filter is mounted in the mono-fuel configuration. The integration plate also may deliver either fuel types into the existing engine fuel intake port thus the system does not require the creation of a secondary fuel intake port for the secondary fuel. The integration plate may also be situated such that it minimizes the space it must use within the engine compat anent and it may use the preexisting engine mounting points designed for the fuel filter in the mono-fuel system.

摘要： The air-fuel ratio feedback control is performed by using a first correction value which is determined depending on a difference between a detected air-fuel ratio (A/F) of an air-fuel mixture and a target A/F and a second correction value which is determined depending on the property of the fuel. Further, fuel property learning control is carried out to correct the first correction value and the second correction value so that an absolute value of the first correction value is not more than a threshold value, when the absolute value of the first correction value is larger than the threshold value after performing the charging with fuel. A combustion continuing correction value range, which is a range of the second correction value to allow the A/F of the mixture to be included in an A/F range in which combustion can be continued, is stored, and the second correction value is set to a value within the combustion continuing correction value range if the A/F feedback control and the fuel property learning control are interrupted.

摘要： A method for estimating a specific gravity of a gaseous fuel is described. The gaseous fuel may power an engine and the engine may include a cylinder, a gas valve configured to supply an intake port of the cylinder with the gaseous fuel, a gas rail configured to deliver the gaseous fuel to the gas valve, and a microprocessor adapted to perform the method. The method may comprise establishing a pressure wave in the gas rail by opening and closing the gas valve, wherein the pressure wave travels at the speed of sound in the gaseous fuel. The method may further comprise determining a frequency of the pressure wave in the gas rail, and estimating the specific gravity of the gaseous fuel based on the frequency of the pressure wave.

摘要： In a method and a device for identifying the fuel quality in a fuel tank of an internal combustion engine, a reference volume with fuel is provided, which does not intermix with the fuel in the fuel tank when the fuel tank is refilled. After startup of the internal combustion engine, fuel from the fuel tank and from the reference volume is sequentially sucked into the internal combustion engine and parameters which depend from the fuel quality of the sucked-in fuel are measured and evaluated for both the fuel tank and the reference volume. If the parameter differ from one another, it can be concluded that the fuel quality of the fuel in the fuel tank before startup of the internal combustion engine has changed. A quantity (fuel factor) can then be taken into consideration in the mixture pre-control.

摘要： The invention provides a method for controlling a compression ignition internal combustion engine, which can easily deal with a wide range of demand loads with a single fuel. The compression ignition internal combustion engine includes a fuel containing an ignition improver, and as the demand load increases, part of the ignition improver contained in the fuel is changed into a material having a reduced ignitability improvement capability, and the fuel having reduced ignitability is supplied to the compression ignition internal combustion engine. A fuel having part of the ignition improver changed into a material having a reduced ignitability improvement capability, and thus having reduced ignitability, and a fuel with the ignitability improvement capability of the ignition improver maintained are mixed together in any ratio, and supplied to the compression ignition internal combustion engine.

摘要： A manifold valve controller (30, 32) designed to be embedded within the casing (24) of a throttle actuator in a manifold valve assembly for a gas fueled internal combustion engine. The controller (30, 32) senses the current position and current velocity of the valve (14) and calculates a rest position of the valve (14) if the valve commenced deceleration from its current position and velocity. The controller (30, 32) then compares the calculated rest position with a demanded position for the manifold valve (14) in order to determine whether the current position or the rest position exceeds the demanded position The controller (30, 32) then accelerates or decelerates the valve (14) to the demanded position as required, based on the comparison A feedback position sensor such as a potentiometer (22) provides the means for sensing the current position and velocity of the valve (14). By locating the controller (30) as close as possible to feedback potentiometer (22) problems caused by background electrical noise are minimized.
