Abstract: The present invention provides a system and method of adaptively setting the idle speed of an internal combustion engine based on instantaneous power requirements of the engine. By adaptively setting engine idle speed based on instantaneous power requirements of the engine as well as the power requirements of any auxiliary devices, the noise and exhaust emissions of the engine may be reduced as well as improving fuel consumption efficiency. The engine's electronic control unit (ECU) is designed to regulate an idle speed controller based on current feedback received from sensors operationally connected to the engine as well as the various auxiliary devices. The ECU regulates the idle speed control such that the engine electronics are sufficiently energized to run the engine, but the engine idle speed is also set to a level that takes into account the instantaneous power requirements of the various system components and/or devices.

Abstract: In a motor grader, controls for running the vehicle at a constant speed are provided when a work for improving a land surface with a blade is started by running a working vehicle at a low speed from the low idling start. With this operation, it is possible to perform the work for improving a land surface by maintaining an actual revolution speed of the engine 5 at a value obtained by subtracting a prespecified revolution speed from the revolution speed for low idling to run the working vehicle at a low speed. With this feature, it is possible to continue the work at a constant speed and also to prevent occurrence of engine stop during the work at a low speed, when a higher duty of the engine is required and the actual revolution speed drops like in the case where an ascending slope of the land to be improved becomes large or where the cutting rate temporally increases due to local irregularities of the land surface during the land surface improvement work.

Abstract: The present invention is an ignition control system controlling ignition firing timing of an ignition element associated with an engine. The engine includes an output shaft powering a water propulsion device, an intake system including a throttle valve, and a sensor providing an output signal corresponding to each revolution of the output shaft. The ignition control system calculates a base ignition firing timing from a time between successive previous output signals, and determines if a low-temperature idle condition of engine exists from the sensed throttle angle and coolant temperature. If such condition exists, the ignition control system also determines a compensation value to compensate ignition timing to either the advance or delay side to generally match a target engine speed for a given coolant temperature, and modifies the basic ignition firing timing by the compensation value.

Abstract: A number of embodiments of engine control for marine application wherein the engine is called upon to operate for long periods at speeds substantially below normal idling speed. This is encountered when trolling. The arrangement includes a system for substantially retarding the spark to assist in shifting and also to maintain stability when running at these low speeds. Adjustments may be made in air flow and fuel supply amounts so as to further augment the smooth running and avoid stalling under these trolling conditions. Various control routines for achieving appropriate ignition timing under the widely varying instantaneous speeds during trolling are also disclosed.

Abstract: A basic fuel injection amount is calculated based on the intake air amount detected by an air flow meter, and the basic fuel injection amount is corrected based on a phase delay of an intake air amount variation between the engine and air flow meter so as to calculate a first correction injection amount. The first correction injection amount is corrected to a second correction injection amount based on an increase amount which is different according to whether or not the engine is in the idle running state. A fuel injector performs fuel injection based on this second correction injection amount. The increase amount is determined by multiplying a difference between the first correction injection amount and basic fuel injection amount, by a predetermined gain. Due to this, a shift of the air-fuel ratio to the lean side when a new load such as an air conditioner is exerted on the engine in the idle running state, is suppressed.

Abstract: An engine control system digitally stores corresponding values of timing angles and engine speeds and selects the timing angles based on the operating speed of the engine. In the engine speed range near idle speed, the timing angle is set to a pre-selected angle after top dead center (ATDC) and the relationship between engine speed and timing angle calls for the timing angle to be advanced from the pre-selected angle after top dead center (ATDC) to successively advancing angles which subsequently increase angles before top dead center (BTDC) as the engine increases in speed. In one application, a timing angle of 10 degrees after top dead center (ATDC) is selected for a engine idle speed of approximately 800 RPM. This relationship, which is controlled by the engine control unit, avoids stalling the engine when an operator suddenly decreases the engine speed.

Abstract: An idle speed control system for a direct injection spark ignition engine controlled to operate in either homogeneous air/fuel modes or stratified air/fuel modes. A desired idle speed is set to optimize fuel economy and avoid rough engine operation during various air/fuel operating modes. During rough idle conditions and non stoichiometric air/fuel operation engine air/fuel is enriched until either rough idle ceases or a rich air/fuel limit is reached. During smooth idle operation, and non stoichiometric air/fuel operation, engine air/fuel is enleaned until either rough idle occurs, a lean air/fuel limit reached, or desired fuel economy attained. After the lean limit is reached, and when operating in a non-stoichiometric non-stratified air/fuel mode, and when not operating at desired fuel economy, ignition timing is advanced until an advance limit is reached and desired idle speed is thereafter decreased.

Abstract: A flow controller in a flow control valve for an internal combustion engine. When the flow control valve is operated in a closing direction upon the occurrence of an abnormal state in the flow control valve such as sticking, resonance frequency vibration is applied to the valve so that a sliding resistance force of a screw mechanism can be lowered and the valve can be closed. To prevent problems with the flow control valve such as being out-of-control, a setting time is added to a drive period according to the variation in the motor torque. Because the flow control valve can be reliably closed, and an out-of-control condition of the flow control valve can be prevented, an incorrect operation of the engine can be avoided.
