초록 ▼

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.

What is claimed is: 1. An engine controller controlling start and stop of an engine that has an intake port to which a fuel is injected, the engine controller comprising: a stroke estimating means for estimating, during a shut-down period of the engine, a stroke of each cylinder when the engine is stopped, the stroke estimating means storing an estimated result; a fuel injection control means for injecting a fuel, which is required to start the engine in a next starting time, into the cylinder which is estimated to be stopped in a power stroke or in a compression stroke based on the estimated result; and a starter-motorless-start control means for igniting and combusting an air-fuel mixture in the cylinder that is estimated to be stopped in the power stroke so as to begin a cranking by a combusting energy of the air-fuel mixture, the starter-motorless-start control means igniting, at a next ignition timing, an air-fuel mixture in the cylinder that is estimated to be stopped in compression stroke in order to start the engine without an aid of a starter. 2. The engine controller according to claim 1, wherein the stroke estimating means calculates a first parameter representing a movement of the engine and a second parameter representing an energy restricting the movement of the engine, estimates a third parameter representing a future movement of the engine based on the first and the second parameters, and estimates strokes of each cylinder when the engine is stopped based on the third parameter. 3. The engine controller according to claim 2, wherein the stroke estimating means estimates a future instantaneous engine speed as the third parameter, and estimates that the engine will stop in a cylinder condition at a time when the future instantaneous engine speed drops below a predetermined speed. 4. The engine controller according to claim 1, further comprising: a stop position control means for stopping the engine by means of increasing an intake air amount in a compression stroke cylinder, which is estimated to be stopped in the compression stroke, during an intake stroke period just before the engine is stopped, in order to increase a compression pressure in the compression stroke cylinder. 5. The engine controller according to claim 1, further comprising: an auto stop means for stopping the engine by terminating a fuel injection and a spark ignition when a predetermined auto stop condition is established with the engine at idle, wherein the stroke estimating means performs a stroke estimation of each cylinder, and the fuel injection control means performs a fuel injection control, during a shut-down period of the engine based on an operation of he auto stop means, and the starter-motorless-start control means ignites an air-fuel mixture in the cylinder which is estimated to be stopped in the power stroke to start a cranking by a combustion pressure thereof based on the stored estimated result when a predetermined auto start condition is established, and ignites an air-fuel mixture in the cylinder which is estimate to be stopped in the compression stroke to start the engine without an aid of a starter. 6. The engine controller according to claim 1, wherein the starter-motorless-start control means determines whether a starter-motorless-starting, which represents a starting of the engine without the aid of the starter, can be conducted based on an engine stop position, an engine stop period and an engine temperature, and when the starter-motorless-start control means determines that the starter-motorless-start cannot be conducted, a cranking of the engine is performed by the starter.
