Embodiment Construction

[0054] In the drawings listed above, especially Figure 1 to Figure 6 Among them, the device provided by the present invention as a whole is D, comprising one or more sensors 1, also called sensing devices, which are at least partially surrounded by the fluid flowing in the fuel conduit 2 of the internal combustion engine in the operating state.

[0055] Said fuel conduit 2 is of the "fuel rail" type, that is to say it comprises a fuel inlet 3a and several fuel outlets 4; Figure 4 and Figure 5 Among them, the fuel inlet 3a is located at one end 2a of the fuel conduit, and the fuel outlet is in communication with the fuel injector (not shown) of the internal combustion engine. The internal combustion engine is a variety of fuel engines that can work in different fuel environments, such as gasoline and ethanol etc.

[0056] As shown in the figure, the dry part of the sensor 1 includes a housing 5 for circuit components, the housing 5 is closed by a cover 6; through a three-p...

Abstract

The invention provides a device for detecting fuel of an internal combustion engine. In particular, the device is fitted with detachable means for fastening the device to the associated conduit so that it can be installed in a "fuel rail" for high pressure fuel injection engines such as those used in fuel injected engines fuel supply.

Description

technical field [0001] The present invention relates to a device for detecting properties of a liquid, such as detecting the type of at least one liquid, and / or the percentage of different liquids in a mixed liquid, and / or the elemental composition of the liquid, and / or the concentration of an element in the liquid , such as detecting a certain liquid fuel for internal combustion engines, such as gasoline, diesel, ethanol, etc. [0002] Preferably, the present invention relates to a detection device equipped with suitable means, in particular of hydraulic and / or mechanical type, for connecting or fitting the detection device to a fuel conduit of a flammable liquid or fuel, in particular Or fitted to the fuel lines connected to the valves or injectors of the internal combustion engine, for example so-called "fuel rails". [0003] Typically, the connection or assembly means is removable from the device, eg for repair or replacement of the device or associated fuel conduit. Ba...
