摘要： The invention precisely achieves an air fuel ratio control precision in each of operating regions of an engine (10), particularly a demand air fuel ratio at a time of an engine transition. In a fuel control system correcting a basic fuel amount in such a manner as to estimate a fuel adhered to an air intake pipe (13) of an engine (10) and an evaporated fuel from the adhered fuel so as to achieve a demanded air fuel ratio, a temperature of a fuel adhered portion is estimated on the basis of an amount relation between the fuel to be adhered (Fijw) and the already adhered fuel (Ffw), or a heat quantity balance. A fuel adhesion amount and a fuel evaporation amount (Ffwv) are determined on the basis of the estimated temperature.

摘要： A system and method for load sharing processing operations between a vehicle mounted station (105) and a stationary base station (25) having a large capacity host computer (18) is described. The vehicle mounted station (105) has detectors for determining operating conditions of a vehicle and controllers (3,4,501) for varying the operating conditions. The controllers (3,4,501) are connected to a transmitter-receiver (5) which is arranged to communicate over a path (10) with a transmitter-receiver (11) of the base station (25). The base station (25) has a host computer (18) having a large memory capacity. At predetermined intervals, for example, distance of travel or at engine stop, the vehicle transmitter (5) transmits operating conditions to the base receiver (11) for data processing and the base transmitter (11) then transmits processed data back to the receiver vehicle (5), whereupon the controllers (3, 4, 501) modify the vehicle operating conditons. The vehicle operating conditions may be an indication of life expectancy of fuel injectors or sensors, updating data processing maps. The presence of abnormal operating conditions may be detected by the vehicle mounted station (105), evaluated by the base station (25) and an emergency warning indication provided back to the vehicle mounted station (105), or if the abnormal condition is not of an emergency nature then counter measures are transmitted from the base station (25) to the vehicle mounted station (105).

摘要： A method and an apparatus for control of engine fuel injection are characterized by detecting the state of the acceleration of the engine and also judging whether or not the engine is in a specific acceleration state, by, when the engine is judged to be in a specific state of acceleration, using such a value as a crank angle obtained in advance in order to predict the air mass flow rate of the air flowing into a specific cylinder having undergone a fuel injection, by using the predicted air mass flow rate or the crank angle to determine a proper asynchronous fuel injection quantity for the above-mentioned acceleration state for the specific cylinder, and then by performing an asynchronous injection. Thus, they make it possible to calculate the shortage of fuel occurring with the synchronous injection even at the early stage of acceleration by using various variables so as to determine a proper supplemental fuel supply quantity (asynchronous injection quantity) for achieving a desired air fuel ratio in various drive modes.
