IPC: F02D41/34
Filed: 1994-12-14
Abstract: PURPOSE: To cope with the rapid change in an engine operation state and prevent the occurrence of an engine stall by a method wherein an engine rotation speed is detected in such a state to be displaced to that in a past in answer to the delay in detection of an intake pipe pressure, a fuel injection time suitable to an actual engine state at a present point of time is determined and fuel is injected for the time. CONSTITUTION: An ECU 10 incorporating a control map to specify an injection time at an intake pipe pressure and an engine rotation speed, a fuel injection time is determined from a control map based on detecting signals from a pressure sensor 11 and a number of revolutions sensor 12 to control opening and closing of an injector 8. In this case, when a throttle opening is below a given amount, and an engine rotation speed at a point of time displaced to a past from a current point of time by an adequate time set in answer to a delay in detection of an intake pipe pressure is determined. Based on an intake pipe pressure at a current point of time and a past engine rotation speed, a fuel injection time is determined from a control map and fuel is injected through an injector 8 according to the obtained fuel injection time.

IPC: G01M13/02
Filed: 1989-11-30
Abstract: PURPOSE:To enable operation regardless of parameters of a sample by storing characteristic data prescribing relationships between engine revolutions and torques corresponding to parameters from one to others. CONSTITUTION:A data storing section 11 (12) stores characteristic data prescribing relationships between engine revolutions N and torques T in terms of throttle openings (intake pressures) with a throttle opening theta (intake pressure P) as parameter. When a revolutions detection value N and an opening signal thetaare inputted into a computing section 2, it 2 determines a torque specified value T corresponding thereto based on values N and theta and a characteristic data in the storing section 11 and then, an intake pressure signal P based on the values T and N and a characteristic data in the storing section 12 is determined. As a result, a driver 3 is driven based on the value T to operate an automatic transmission gear 4 while the signal P is applied to an actuator 6, where it is converted to a pressing force corresponding to the intake pressure to be applied to the transmission gear 4. This permits a test with the intake pressure as transmission parameter using a generator having the signal theta as input.
