摘要： During a shut-down period of an engine based on an idle stop control, a computer estimates a power stroke cylinder and a compression stroke cylinder when the engine is stopped. A fuel is injected into the power stroke cylinder and the compression stroke cylinder in an intake stroke just before the engine is stopped. An air-fuel mixture is hold in each cylinder with the engine stopped. When an auto start is required while the engine is stopped, a spark ignition is performed in the power stroke cylinder to start cranking of the engine by combustion energy. At nest ignition timing, a spark ignition is performed in the compression stroke cylinder to start the engine without an aid of a starter.

摘要： An engine stopping and starting control device includes a prediction means, a control means, and a start control means. The prediction means predicts a cylinder on a compression stroke upon a stop during a process for stopping an engine. The control means controls a fuel injection upon a stop that injects fuel into the cylinder during the process for stopping the engine to seal an air-fuel mixture therein. The start control means fires the cylinder to generate a first explosion to start the engine.

摘要： A control apparatus for an engine increases an intake air quantity just before engine stop to increase a compression pressure in a compression stroke. As the compression pressure is increased, a negative torque in the compression stroke increases and obstructs engine rotation, and brakes the engine rotation. Thus, a range of crank angle, in which torque is below engine friction, that is, in which engine rotation can be stopped, is reduced. As a result, variation in engine rotation stop position is reduced to be within a small range of crank angle. Information of engine rotation stop position is stored, and the stored information of engine rotation stop position is used at the start of an engine to accurately determine an initial injection cylinder and an initial ignition cylinder to start the engine.

摘要： An engine stopping and starting control device predicts which cylinder will be on a compression stroke upon being stopped during a process for stopping the engine. Fuel is injected into the predicted cylinder during the process for stopping the engine to seal an air-fuel mixture therein. The same cylinder is then fired upon the next start cycle to generate a first explosion to start the engine.
