Abstract (en)
[origin: WO2021156434A1] Injection device (2) for a heat engine (6), comprising: - a flowmeter or a pressure or speed sensor (3) designed to be positioned in or in communication with an intake manifold (4) and designed and/or programmed to provide a measurement (16) which depends on an air flow circulating in the intake manifold, - a control unit (5) designed and/or programmed to control a fuel injection, characterised in that the control unit is designed and/or programmed to receive and analyse the measurement from the flowmeter, or from the pressure sensor or from the speed sensor, and, depending on the measurement, compute a command (17) designed to control a fuel injector (7) so as to control the injection of an amount of fuel which depends on the measurement.
