摘要:
An improved spark ignition system for an internal combustion engine that includes a pair of electrodes disposed to extend from opposite sides and into a combustion chamber to form a spark gap between them that is central to the combustion chamber. Each electrode is integral with a conductive fuel delivery tube that contains a capillary passage and fuel outlet ports adjacent the electrode. The heat from combustion conducted into the electrodes and fuel delivery tubes is used to vaporize the fuel within the capillary passages before it exits the outlet ports as an atomized fog into the combustion chamber adjacent the spark gap. The vaporization of the fuel flowing in the capillary passages absorbs energy from the electrodes and thus performs a cooling effect on the electrodes. The spacing of the electrodes from opposite sides of the cylinder also allows a design that can utilize and increased spark gap to produce a larger spark across the gap.

Embodiments in accordance with the present invention provide an opposed piston, opposed cylinder (OPOC) internal combustion engine. The OPOC engine comprises two cylinders opposed at 180 degrees. A linking element connects two outer pistons so that they move in tandem. A central piston is disposed between and moves in opposition to the outer pistons. The linking element is adapted to drive secondary mechanisms in accordance with embodiments of a drive shaft, electric generator, hydraulic pump, pneumatic pump, and gear-driven mechanisms, among others.

An improved lubrication system and method for the normally contacting and abutting piston pin and connecting rod journal bearing surfaces of an internal combustion engine that includes an inertia pump in a connecting rod. The inertia pump reacts to the movement of the connecting rod and conveys a predetermined measure of lubricating oil at a high enough pressure to overcome the forces which cause the surfaces to normally maintain contact. By separating the normally contacting surfaces of the pin and the connecting rod journal, the surfaces become lubricated. Several embodiments of inertia pumps provide variations in implementing the invention.

A highly efficient radiant burner assembly (100) for use in a patio heater or the like in areas where people prefer or require low NOX emissions. The efficiencies are created through the use of a spherical burner element (116) that is either formed of a high temperature steel wire mesh or stamping containing apertures of a predetermined size to allow combustion to remain within the burner element and to not cause the temperature of the burner element to exceed the temperature at which NOX are developed. Coating the burner with a catalyst also aids the low emission combustion process. Additional efficiencies are provided by atomizing the fuel before it is mixed with air and by the use of a laminar flow heat exchanger (940) that utilizes a fluid media flowing in a helical coil condenser unit.

An electrically controlled turbocharger having a substantially vertically oriented shaft interconnecting a turbine and a compressor. The vertical orientation serves to eliminate the effects of gravity on the rotating components. Placing the turbine vertically above the motor and compressor and provides additional cooling through convection of heat produced by hot exhaust gas flowing through the turbine. A lubricating system utilizes scavenged air from the compressor to draw lubricating oil through internal passages of the motor housing to maintain a desirable oil sump level, ventilate the auxiliary induction motor, and provide pressure to the oil seals of the motor cavity.

An inlet air compressor for an internal combustion engine is provided which has one inlet and a plurality of outlets. Within the compressor are disposed a plurality of diffusers coupled to the plurality of outlets. The flow is divided among the plurality of outlets so that at conditions of low overall flow rate through the engine, which would, in a compressor according to the prior art, ordinarily surge, allow the flow to be substantially discontinued through one or more diffusers and continue at through the remaining diffusers. In this way, the diffusers with flow operate within an acceptable operating range and avoid a surging condition. The present invention is directed to engines having a wide range of flow rates. A couple of examples are gasoline engines and variable displacement engines.

A heat exchanger wherein the media that take part in the heat transfer are separated from one another. To provide a compact heat exchanger that has a high efficiency, the heat exchanger is formed by a base body, one surface of which is provided with at least one groove that extends from the inlet to the outlet and that is sealed by a cover, in the form of a flow channel, for the heat-absorbing heat transfer medium. The other surface of the base body has a plurality of channels and/or pores for the heat-emitting medium.

The invention relates to a radiant burner for boilers, consisting of a sheet metal support (1), with a gas feed line (3) leading to a gas inlet port (2) in the sheet metal support (1) and a curved burner surface (4) of wire cloth arranged at an opposite side of the sheet metal support. According to the invention, the burner surface (4) is of hemispherical shape and at least one similarly hemispherical gas distributor (5) of perforated sheet metal is arranged concentrically under the burner surface and is spaced therefrom at a distance (A) which is considerably smaller than the diameter (D) of the hemisphere of the burner surface (4) and is also affixed to the sheet metal support (1). The diameter (D.sub.1) of the gas inlet port (6) corresponds substantially to the diameter (D.sub.2) of the hemispherical gas distributor (5). Such a construction fulfills the requirements of a large gas inlet port, stability of the burner surface and good gas distribution over the burner surface.
