Description

Kevin Owen Bonser Douglas Robert Bonser Riley Road, Mt Helena, Western Australia / Australia water vapor injection device for machines with internal Incineration Priority: June 22, 1971, Australia, No. PA 5272/71 The invention relates a water vapor injection device for machines with internal combustion.

It is known that the connection of water vapor in the fuel / air Mixture of a machine with internal combustion the work performance of the machine vastly improved.

The many facilities that have been proposed for this purpose all have had certain drawbacks which prevent extensive use to have. The object of the invention is to provide a device which are relatively simple and economical in terms of construction and Operation is and an appropriate amount of steam during normal work area the machine delivers.

In one embodiment, the invention resides in a steam injection device for machines with internal combustion, which includes a steam generating chamber, which is provided with means to maintain a predetermined level of water in it with the outlet of the chamber connected to the suction line of the machine is and the chamber is heated by exhaust gases, which by a power, the is connected between the exhaust pipe and the chamber and by a power, which is connected between the Kemmer and the suction line.

The invention will be further developed with reference to the drawings explained which represent: Figo 1 an elevation in section of the steam pferzeu-gungskanmer, 2 shows a diagram to explain the position of the device according to the invention in relation to an internal combustion engine0 According to the drawings a substantially rectangular box 11 has an inner partition 12 which encloses the box divides into an upper and a lower compartment 13 and 14 respectively.

The partition wall 12 is made of a corrosion-resistant material with good heat transfer properties, like zOBo copper Each compartment 13, 14 is provided with an inlet and outlet.

The inlet 15 of the lower compartment 14 is through to the exhaust pipe 16 a copper pipe section 17 is connected, while the outlet 18 is connected to the suction line 19 is connected via a second piece of plucking pipe 200 The inlet 21 of the upper Compartment 13, which forms the steam generating chamber, is connected to a water storage tank 22 connected. The chamber inlet 21 is provided with a float valve 23, in order to maintain a predetermined water level in the chamber, the outlet 24 of this chamber is connected to the inlet line 19 via a piece of copper pipe 25. The outlet from the chamber can be closed with a fine wire mesh (not shown) be provided to prevent large water droplets from entering the outlet pipe 25 enter.

Preferably the steam and exhaust lines are connected to the inlet line connected via a spacer block located between the carburetor and the inlet line and if required, the steam and exhaust pipes are equipped with suitable nozzles, to regulate the flow of steam and gas therethrough. Also karm if desired a filter in the gas line between the box and the inlet line built-in to prevent solid particles from entering the inlet pipe 0 -When operating, the reduced pressure in the inlet line will cause Pass hot exhaust gases through the branches to heat the water in the chamber. Because it is subjected to a reduced pressure, the water will be at a lower one Boiling temperature than the normal and the generated water vapor is in the inlet pipe injected0 -The injection of water vapor into a machine with internal combustion in the inventive device will ensure that the machine with works with greater effectiveness and that the gases emerging from the outlet unite Have substantially lower carbon monoxide content, If an inventive The device was used in a 1969 Palcon 500 3.6 liter trolley performance (miles / gallon of fuel) by more than 10%. In addition, the carbon monoxide content increased in the exhaust gas from 5 1/2% to 2% abO The hydrocarbon emission was also from 550 ppm reduced to 200 ppm0 drive the invention with reference to a specific one Embodiment has been explained, it is not limited to this. The water vapor generating device can be of any suitable shape other than rectangular and divided into two compartments be shared by other suitable means which transfer heat from a compartment guarantee in the other.
