摘要： A misfire detecting apparatus for an internal combustion engine has a start determinator, a rotation counter, a misfire detector, a misfire calculator, a setting means, an abnormality determinator, and a warning means. The start determinator determines a starting condition of the internal combustion engine. The rotation counter counts a total number of rotations of the internal combustion engine. The misfire detector detects a misfire of the internal combustion engine. The misfire calculator calculates a rate of misfire using data from the misfire detector, and the rate of misfire is the number of misfires per a predetermined total number of rotations. The setting means sets a basic rate of misfire in response to the start condition of the internal combustion engine. The abnormality determinator determines an abnormal condition of the internal combustion engine when the rate of misfire calculated by the misfire calculator is greater than the basic rate of misfire set by the setting means. The warning means warns of an abnormality of the internal combustion engine when the abnormality determinator determines an abnormal condition of the internal combustion engine. The detection whether the internal combustion engine is abnormal or not can be accurate by this misfire detecting apparatus.

摘要： The method for determining segment times (Tk) required for controlling an internal combustion engine includes providing a transducer disk (17) connected to a camshaft of the engine with a plurality of markings equally spaced from each other on the transducer disk; measuring respective segment times (Tk) between detection of corresponding pairs of markings on the transducer disk (17) by means of a camshaft sensor (21); triggering fuel injection events and combustion events in order to trip acceleration events at a substantially constant camshaft rotation speed; determining a resulting acceleration quotient (Qk) for a current segment time as a quotient of the current segment time divided by a preceding segment time and correcting a following segment time by means of the acceleration quotient (Qk) for the current segment time. The method is not performed when the internal combustion engine has a crankshaft with a properly working crankshaft sensor for measuring crankshaft rotation speed.

摘要： A failure determination system and method for an internal combustion engine and an engine control unit are provided which are capable of properly determining a failure of a variable valve mechanism for inactivating a valve system associated with at least one of cylinders during a predetermined operation of the engine, by discriminating a misfire caused by the failure of the mechanism from a normal misfire. Fuel injection valves inject fuel for each cylinder and oxygen concentration of exhaust gases is detected. A misfire condition is detected on a cylinder-by-cylinder basis. Fuel injection to a misfiring cylinder is stopped. A failure of the mechanism is determined, when a parameter based on the oxygen concentration detection indicates a richer value of an actual air-fuel ratio of the exhaust gases than a predetermined reference value does, under a condition of the fuel injection being stopped.

摘要： There is provided a failure diagnostic system of an evaporated fuel processing system, which comprises a first failure diagnostic device that shuts off an evaporated fuel purge passage connecting a fuel tank and an engine intake passage from the air and determines whether there is any leakage from a large hole by monitoring the degree of increase in pressure in the fuel tank in which engine intake negative pressure is introduced; and a second failure diagnostic device that reduces a pressure the fuel tank to a predetermined negative pressure and seals off the fuel tank from the air to carry out failure diagnosis as to whether there is any leakage from a small hole by monitoring the degree of increase in pressure in the fuel tank. An operating range of the second failure diagnostic device is set to substantially include an operating range of the first failure diagnostic device and to be extended from the operating range of the first failure diagnostic device to include a lower intake negative pressure range.

摘要： An ignition apparatus including a primary and a secondary winding for producing a spark voltage, an ion current detection circuit for producing an ion current signal, a slope detector and a knock detector. The slope detector determines when the ion current signal exhibits a slope indicative of a time period when knock is likely to occur, and de-asserts a knock reset signal. The knock reset signal holds the knock detector in reset, thus disallowing or masking the processing of signals by the knock detector that may be mistaken for knock.

摘要： A system for monitoring fuel consumption and optimizing refueling of a vehicle. The system includes a fuel level sensor designed to be mounted on a fuel tank. The fuel sensor has a transducer, such as an ultrasonic transducer, for generating a distance signal that represents the distance between the sensor and the surface of the fuel in the fuel tank. A processor coupled to the transducer is programmed to convert the distance signal to a percentage of capacity signal, calculate the volume of fuel within the fuel tank, and create a message that includes information regarding the volume of fuel in the fuel tank. The processor of the fuel level sensor is coupled to a network that may include a dispatch terminal, a fuel optimization server, and a fuel-price-by-location service. The network calculates an optimal location for refilling the fuel tank and a route to travel to the location. It broadcasts a message containing the refueling and route information to the vehicle information system, and devices coupled to the vehicle information system then display the message to inform the driver of the vehicle when and where to refuel.
