摘要:
An apparatus for the injection of fuel into combustion chambers, in particular of self-igniting internal combustion engines, having an injection nozzle (10) and a subsequent glow body (20), which has a conduit (30) surrounded by heatable walls (26) and serving for the passage therethrough of the injected streams. At least one lateral opening (32) discharges into this conduit (30), the opening preferably communicating with a region (46) of the combustion chamber (36) remote from the core region of the ignition. The air aspirated through the lateral opening (32) warms up and enters into the peripheral zone of the injected streams, where the result is an air-fuel ratio and temperature conditions which are very favorable for ignition. Less heat energy is required to initiate the ignition than in the known apparatus of this general type. By eliminating the conventional glow plugs, which interrupt the movement of air in the combustion chambers, increased power is attained and the emission of soot is reduced sharply.
摘要:
An apparatus for injecting fuel into the combustion chamber of an internal combustion engine, having an injection nozzle and following the injection nozzle a partition (12, 23, 29) which is provided with through openings (13) for the injection streams and is embodied as a guide device for a partial flow of combustion air, which flow is accelerated by the injector action of the fuel streams in the through openings (13). A device (26, 24, 32) for preheating the partial flow of combustion air is also secured to the partition (12, 23, 29). In this apparatus, the partial flow of combustion air circulates virtually continuously through the partition (12, 23, 29) embodied as a guide device, and the acceleration caused by the injector action of the fuel streams increases with increasing engine rpm. This has the advantage that over the entire power and rpm range of the engine, a uniform course of combustion and a reduction of toxic emissions is attainable.

An apparatus for injecting fuel into combustion chambers, in particular of self-igniting internal combustion engines, is proposed, in which a fuel injection nozzle generates an aimed fuel spray and in which an air guide device and a heating device are provided. The fuel being injected is accompanied by an air flow which passes the heating device. The heating device has at least two heating elements of different effectiveness, of which at least one element serves for rapid heating and the other element is provided for continuous use.
摘要:
Device for fuel injection in combustion chambers of, in particular, selfigniting combustion engines with an injection nozzle (10) and a subsequently switched incandescent wire (20) which has a conduit (30) surrounded by a double heating layer (33) on the inside for passing through of the injection streams. The double heating layer (33) consists of an inner heating layer (35) which is separated from a second heating layer (37) by an electrical insulator. In the parallel as well as the series switching of the two heating layers (35,37), a two stage heating of the double heating layer (33) is possible. The inner heating layer (35) reaches the required end temperature required for ignition in a relative short time, while the second heating layer (37) assures a high energy density of the ceramic support mass (38).
摘要:
A system for injecting fuel into the combustion chambers of an internal combustion engine, comprising an injection nozzle and a glow coil which is connected downstream and is enclosed by a sleeve. The sleeve contacts one end of the glow coil on the combustion chamber side and is connected with a current lead. The other end of the glow coil is grounded via a contact ring body, a heat protecting ring and the nozzle body of the injection mozzle. This arrangement has the advantage that an insulation of the contact ring body relative to the heat protection ring is dispensed with and the latter can be supported immediately at the contact ring body.
摘要:
A device for injecting fuel in combustion chambers, especially for self-igniting internal combustion engines, is proposed, in which a fuel injection nozzle, by aspirating air through an air guide device in the manner of a jet pump, generates a fuel spray that is surrounded by an air envelope. This air-enveloped fuel spray is directed through a heating element, the heat generation of which is distributed in such a manner over its length that a desired heating profile along the heating element is produced. The type of heating profile depends not only on the properties of the material making up the heating resistor but also on its structural makeup and its electrical bonding. A highly suitable material for the heating resistor is molybdenum silicide (MoSi.sub.2).
摘要:
A cooling system and a method of operation of a cooling system for an internal combustion engine in which the coolant is a heat-retaining storage medium capable of being super-cooled. A suitable medium is found to be, especially, sodium acetate trihydrate mixed with water. The coolant according to the invention may be caused to solidify and crystallize just prior to an intended engine starting, thereby releasing the latent heat of fusion and preheating the engine. The preheating of the engine results in reduced run-up times, a reduced degree of fuel enrichment during cold starting, a decrease in toxic exhaust components during cold starting and decreased water and tear. The invention provides for valves in the cooling system which isolate the engine from the remainder of the cooling system until the coolant has been reliquified completely.

A micro electronic component, preferably in the form of an electronic memory, includes the use of clusters as an electronic memory. Also disclosed as part of the present invention is a method for fabricating a micro electronic component. The present invention contemplates fabrication of an especially compact electronic memory that works especially with single-electron transistors or single-electronic transfers. According to the present invention, clusters with a metallic cluster nucleus are arranged in parallel grooves essentially in lines or rows and are connected individually to first and second connecting electrodes, such that individually the clusters can be electrically modified or polled independently of each other.
