An elongated pipe connecting the apparatus to the fuel metering device may have internal ribs which promote greater vaporisation of the fuel and separation of unvapourised fuel and impurities.
The fuel metering and the suction air metering are independent from one another.
The invention relates to a method and a device for controlling fuel metering in an internal combustion engine.
Such control may also be used in fuel metering.
An electronic fuel management control module (EFM) provides an output signal to the fuel metering device to control the flow of the fuel in the convertor (10).
To apportion the amount of fuel pre-injected, a pre-injection unit (27) is provided, and to apportion the amount of fuel injected during the main injection, a fuel injection pump of conventional design is provided.
The injection event involves delivering the liquid fuel and the gaseous fuel, with the metering of the gaseous fuel delivered being adjusted to allow for the quantity of liquid fuel delivered with the gaseous fuel.
The quantity of gaseous fuel also comprises a metered quantity, with the metering of the gaseous fuel being regulated by prediction.
This method is characterised in that, during a first step when the load increases, the control organ for dosing the fuel is rotated together with an actuation lever which is connected to a fuel dosing device.
A flow sensing dual pump switching system and method are provided that control the supply of fuel from a dual pump fuel system to a fuel metering unit.
The proposal is for a control system for metering the fuel supply to an internal combustion engine.
An apparatus and a method are described for controlling a fuel metering system, in which the fuel pressure is controlled as a function of the operating state of the internal combustion engine.
The command value integrated by a common integrator to provide and integrated command value which is the fuel flow command that is presented to a fuel metering unit at the engine.
When the load on the engine decreases, the action onto the control organ for dosing the fuel is applied in the opposite direction.
Furthermore, a fuel metering into the at least one cylinder (119) is controlled dependent on the ascertained hydrocarbon content.
The fuel metering device has a control valve (12) actuated by an electromagnet (10) and having a valve member (34).
Fuel-metering is by means of an electromagnetic valve which is directly mounted inside the injection device without requiring a valve housing.
A system is disclosed for controlling fuel metering in an internal combustion engine, in particular an auto-ignition engine.
By taking into account the linear relation between the reciprocal of the air coefficent μ and the quantity of fuel (fuel dosing time), rapid and precise regulation is achieved by means of a simple linear regulating device.
This has the effect of optimising both the metering of the fuel and the engine’s emissions performance.
