ABSTRACT:
In an unthrottled fuel injection type internal combustion engine, a controlled injection logic to generate a first pulse train whose frequency varies with the accelerator position, N cylinder chambers (CCH's) 11, FIG. 1 ), each with a piston, and a distributor (111, FIG. 4) comprising N first devices and a rotor 109 for generating a second pulse each rotation past a first device, N fuel injection/ignition devices (FIGS. 1-2) each having a fuel ignition element (FIE) extending into a CCH to ignite the injected fuel and a fuel injector for injecting fuel towards each FIE at certain time intervals after the rotor passes the associated first device, a first counter for measuring, in time/degree of engine crankshaft rotation (ECR), the time required for M.degree. of ECR, and for determining the rotor angular velocity. Second logic compares the rotor and accelerator pulses counted during a current time interval with the rotor and accelerator pulses counted in the prior time interval to determine if an advance T or a retardation of fuel injection is required and to calculate T in terms of the number of pulses of a given pulse train occurring after a calculated time interval Y after the second pulse caused by the rotor passing the associated first device, and third logic to compute fuel injection time T.sub.x in response to the throttle position, and fourth logic responsive to the end of each time period for implementing the newly computed fuel injection parameters.
