    Abstract: The invention relates to a method for operating an internal combustion engine. According to the method, an exhaust gas produced by the internal combustion engine is conducted across a 3-way catalytic converter arranged in the exhaust duct. A lambda probe detects a value characteristic of an exhaust-gas lambda number upstream of the 3-way catalytic converter, and transmits said value to an engine control unit with an integrated PI or PID regulator. By means of the PI or PID regulator of the engine control unit, through the specification of a setpoint value, a substantially stoichiometric exhaust-gas lambda number is set, and the exhaust-gas lambda number is, with predefined periodic setpoint value variation, deflected alternately in the direction of a lean lambda number and a rich lambda number (lambda modulation). At the start of each setpoint value variation, a pilot-controlled P component with subsequent I component is predefined up to a time t2, wherein the time t2 is defined by means of stored parameters, which characterize a section time behavior, such that the probe signal or a value derived therefrom would have had to have reached the setpoint value specification at said time t2. From the time t2onwards, for a predefinable time period until the end of the respective setpoint value variation, a switch is made to a regulating algorithm which is based on a difference between an actual value and the setpoint value of the lambda probe or a value derived therefrom.

    Abstract: Provided is a control apparatus for an internal combustion engine which is capable of estimating a single composition concentration based on an air-fuel ratio correction amount obtained by using an output of an air-fuel ratio sensor in exhaust gas and optimizing a fuel injection amount by using a concentration estimation value. When fueling is performed again during alcohol concentration change after the fueling, an alcohol concentration estimation period or a start determination period for the alcohol concentration change is extended by an integrated fuel injection amount from initial fueling until refueling, whereby alcohol concentration estimation accuracy is improved with respect to the alcohol concentration change due to the initial fueling and the refueling.

    Abstract: An air-fuel ratio control apparatus is basically provided with an exhaust system, a pair of sensors and a controller. The exhaust system includes an exhaust channel having a main catalytic converter, a bypass channel having a bypass catalytic converter, and a valve mechanism disposed in the exhaust channel to switch a pathway for exhaust gas from the exhaust channel to the bypass channel. The sensors output signals indicative of air-fuel ratios of exhaust flowing in their respective channels. The controller has first and second air-fuel ratio control sections that control an engine air-fuel ratio based on outputs of the sensors, respectively. The controller has a control mode switching section that switches control from the first air-fuel ratio control section to the second air-fuel ratio control section after a prescribed interval of time has elapsed from when the valve mechanism is switched from a closed state to an open state.

    Abstract: An open or closed loop EFI system, integrated on a genset engine or any internal combustion engine, with an electrical sensor and crank position sensor is described. Since a genset engine's exhaust emissions and general performance are a function of spark timing, integration of electrical and crank position sensors on a genset engine provides optimal engine performance and efficiency when the electrical draws fluctuate. The electrical sensor and crank position sensor send data to the electronic control unit (ECU), and this data is used to determine the optimal air-to-fuel ratio (AFR) and optimal spark timing. The ECU varies the spark timing in accordance with the speed and load of the engine and actuates the fuel injector to send the correct amount of atomized fuel to mix with the air flow to be combusted allowing the engine to meet performance.
