摘要:
Fuel properties estimating apparatus for an internal combustion engine includes a controller to determine an estimated component concentration of a component in a fuel. The controller calculates an air-fuel correction quantity in accordance with an actual air fuel ratio of the engine; and calculates an air-fuel ratio sensitivity correction quantity from the air-fuel ratio correction quantity and a fuel properties correction quantity calculated from a most recent value of the component concentration. The controller then determines a new value of the estimated component concentration in accordance with the air-fuel ratio sensitivity correction quantity.

摘要:
In an internal combustion engine (1), air is taken into a cylinder (5) from an intake passage (30) through an intake valve (15). The amount of air taken into the cylinder (5) is controlled to a target intake air amount by having an engine controller (31) operate an intake throttle (23) in accordance with an accelerator opening (APO), taking into account a predetermined response delay (T2). The engine controller (31) calculates a predicted value (Qc1) of the intake air amount on the basis of the accelerator opening (APO), and controls a fuel injector (21) to inject fuel in a target fuel injection amount (Ti) which corresponds to this predicted value (Qc1) at a predetermined timing. In so doing, an improvement is achieved in the degree of precision with which air-fuel ratio control is performed when the internal combustion engine (1) accelerates or decelerates.

Fuel properties estimating apparatus for an internal combustion engine includes a controller to determine an estimated component concentration of a component such as alcohol in a fuel. The controller calculates a new value of the estimated component concentration in accordance with a component concentration variation and a stored previous value of the estimated component concentration. From an air-fuel ratio correction quantity calculated from an actual air fuel ratio, for correcting a fuel injection quantity, the controller calculates the component concentration variation by using a conversion function determined by the previous value of the component concentration.

摘要:
A variable valve controller for internal combustion engines and methods for operating the same. In the variable valve controller, and engine control unit (ECM) calculates a target value of a valve lift (VEL) for an intake valve and transmits it to a controller with a second control unit (VEL-C/U). The VEL-C/U controls the VEL on the basis of the VEL target value, detects a VEL actual value, and transmits it to the ECM. The ECM calculates a target value of a valve timing (VTC), and controls the VTC. Also, the ECM controls a limit value for the VTC target value in accordance with the VEL actual value. Fail-safe control is performed when an error occurs in a communication unit or a sensor. To reliably perform the control in a period from occurrence of an error to detection of the error, the limit value is set with calculation by offsetting a limit basic value set in accordance with the VEL actual value, by a displacement of the VEL within a time necessary for detecting the error.
