Problems solved by technology

[0004] This makes the known vaporizer and thus the associated majority of process operating devices increasingly complex, reduces its interchangeability, increases reliance on necessary maintenance of a large number of parts, causes price increases, and also reduces overall reliability

Embodiment Construction

[0020] figure 1 , 2 , 3 and 4 disclose valve block 1, air inlet 2, air valve 3 is placed in air inlet 2, and air valve 3 can rotate around multi-part mandrel 4, which is part of mechanical metering device , and also discloses a fuel valve 5 placed on a segmented face acting as a metering device on a multi-parted mandrel 4, a lever 6 is attached on top of the mandrel 4, and a groove 7 may be engraved on the air valve 3 on the surface. Parts 1-7 are the main parts of the carburetor 8 schematically presented, the carburetor 8 presented so far in the practice / design of the invention is entirely mechanical. By way of mechanical fixation "to be explained" or "to be defined", said metering device 4, in all pressure situations and applications (in each pressure situation and application the lever 6 sets the position of the fuel valve 5), maintains The stoichiometric ratio between the quantities of air and fuel. Said evaporator 8 ensures a nearly unimpeded flow of air through the a...

Abstract

The present invention describes a carburetor (8) which comprises an air inlet (2) including a mechanically adjustable air valve (3), a mechanically adjustable sprayer that connects the air inlets, and a mechanically measuring device that is connected to the air valve and the sprayer and sustains the stoichiometric ratio between the amount of the air and the fuel. Besides, the vaporizer comprises a fuel pressure adjusting device (13) which affects the fuel pressure according to one or more than one power engine load parameter, and under the fuel pressure the vacuum suction feeding pipe (12) communicating the air inlets (2) obtains the vacuum signal in the air inlet. The fuel pressure is adjusted according to the measured vacuum signal and the discharging of unburnt fuel is reduced under certain dynamic conditions of the internal combustion engine.

Description

technical field [0001] The present invention relates to a carburetor comprising an air inlet with a mechanically adjustable air valve, a nebuliser communicating in the air inlet, a generally partly electronically manufactured metering device connected to the air valve and the nebulizer. [0002] The invention also relates to a fuel engine equipped with such a carburetor on a vehicle equipped with an internal combustion engine, and to a method of injecting fuel into the air intake. Background technique [0003] Carburetor and fuel engines are generally known. Carburetors for internal combustion engines with a very wide variety of possible applications and mostly based on the two- or four-stroke principle are also known. As far as applications are concerned traction or industrial applications ranging from small to large capacities can be roughly considered. Thus, the application-specific design of a carburetor is always a compromise between price and performance, eg, ease of...
