초록 ▼

A method for controlling fuel supplied to an engine includes steps of conducting tests on a representative model of a family of engines to obtain constants and coefficients of operating characteristics of the representative engine under ambient and induced temperatures and pressures, and creating look-up maps from which such coefficients may be obtained to compute actual operating conditions. When an engine is used in performance of normal operations, sensors are provided to determine actual operating temperatures and pressures which are used to select appropriate constants and coefficients for calculating engine fuel requirements in accordance with an algorithm, and using the calculated result to control flow to fuel to the engine under normal operating conditions.

A method for controlling fuel supplied to an internal combustion engine based upon determination of induced air mass per cylinder per cycle therethrough (IACC) without need for an air flow sensor, comprising the steps of: determining engine operating characteristics from tests conducted on a representative sample of a family of engines at ambient conditions and at selective elevated charge air temperatures (TCH) while keeping all other conditions equal, repeating these tests at a series of engine speed and load combinations, taking measurements of charge temperature (TCH), and developing therefrom look-up maps so that TCH and a selected load demand coefficient KLD can be looked up for any combination of engine speed and load; conducting further tests on said representative sample engine and taking measurements of at both wide open throttle (WOT) and over a range of engine speeds at ambient conditions and at induced exhaust back pressures respectively and, using these measurements and the previously developed look-up maps of TCM and KLD, developing look-up maps of cylinder displacement constant (K1) and exhaust pressure coefficient (K2) over said speed range; inputting signals to a memory of ECU lookup maps of respective coefficients relating to PAT, PEX and TCH for selected engine speeds within said range of engine speeds corresponding to an operating speed range of an operational engine; inputting signals to memory of the ECU look up maps of coefficients relating IACCWOT to IACC at selected load demands below WOT at each said selected speed; providing input signals to the ECU of TCH, PAT and PEX from said sensors while operating engines of said family: calculating IACCWOT from said input signals and said look up maps provided said ECU; calculating based upon IACCWOT, a value for fuel per cylinder per cycle to be delivered to the engine (FPCDELV); providing a signal from said ECU to the engine of FPCDELV to control the delivery of the fuel; subsequent to said tests, operating engines of said family with sensors provided to obtain signals indicating respectively engine load, engine speed, charge air temperature (TCH), ambient pressure (PAT), and exhaust pressure (PEX); calculating from sensor signals TCH, PAT, PEX, and using values from look-up maps of K1, K2, and TCM based on engine load and engine speed, a value for IACCWOT in accordance with the algorithm [Figure] wherein IACCWOT is induced air mass per cylinder per cycle at wide open throttle and DCM is a calibration coefficient previously determined experimentally; looking up a value of KLD based upon load and speed, and calculating a value of IACCLD for existing engine operating conditions according to IACCL-D=IACCWOT X KLD; and controlling fuel supply to the engine based upon said calculated IACCLD.
