Described current pulse width modulation tolerance control and safety protective circuit; because the conduction of oxy-hydrogen electrolytic cell is non-linear; the narrow range of its operating voltage is difficult to obtain level and smooth and meticulous power adjustments with the method for controlling VDC usually in very narrow voltage range.Adopted the pulse direct current power supply, regulated the dutycycle of current pulse, realized that gas production controls needed meticulous power adjustments, stored, produce promptly promptly by demand that the safe operation of usefulness provides assurance for realizing no oxyhydrogen gas.Control of this current pulse width modulation tolerance and safety protective circuit are that the ready-made machine governor of purchase installs pressure switch more thereon additional and is connected lead with thermal switch and forms.
Described gas scrubbing jar fills Yi Shui, and gas is through out-of-date washing, the pure safety that can not influence combustion chambers of internal combustion engines of oxyhydrogen gas that makes output of obtaining.The lid of gas scrubbing jar is made by flexible material and with wiper seal.When pressure increased suddenly, loam cake is quick-fried voluntarily to be taken off, and has guaranteed the safety of gas scrubbing jar.The suction tude of gas scrubbing jar is equipped with the anti-backflow one-way valve.
The oxyhydrogen gas of described water seal backfireproof jar through washing outputs to combustion chambers of internal combustion engines again through the water seal backfireproof pot bottom process liquid level that is raised to waterborne of water-filling.Any tempering takes place and will effectively have been guaranteed the safe operation of entire internal combustion engine micro-hydrogen injection energy-saving exhaust-reduction device by water seal.Water seal backfireproof jar is the same with the gas washing tank, and the lid of water seal backfireproof jar is made by flexible material and with wiper seal.When pressure increased suddenly, loam cake is quick-fried voluntarily to be taken off, and had guaranteed the safety of liquid backfireproof jar.
It is indoor that the hydrogen and oxygen gas mixture of trace is ejected into combustion in IC engine, because that the flame velocity of hydrogen is broadcast speed is fast, petrol engine burning time lag of inflammation shortened greatly, and velocity of propagation of flame is accelerated, and combustion duration shortens.Hydrogen discharges OH, H, O isoreactivity center when burning, can promote velocity of combustion widely.Owing to the catalysis of hydrogen, the long carbochain of nytron fuel molecule is broken to form littler molecule again, makes that burning is more complete.Greenhouse gases and other emission of harmful substances have consequently been reduced; Saved fuel consume; The horsepower and the torque of motor have been increased; Reduce carbon distribution, prolonged oil exchange cycle and engine maintenance expense.This device can be applied in the motors such as diesel oil, rock gas and propane equally.
The present invention utilizes the burning of the combustion characteristic of hydrogen acceleration fuel and utilizes the catalysis of hydrogen to make that the long carbochain of nytron fuel molecule is ruptured, and makes its burning more complete, reaches the effect of energy-saving and emission-reduction with this; This device construction is very simple, and correspondingly reliability is high, is well suited for vast driver operation and maintenance; This device does not need extra oxyhydrogen gas holding vessel, to improve Security; The water electrolytic cell casing of this device is made with engineering plastics and accurate recess-mounted is used at the edge of electrode plate fully, except adjacent electrode plate has electric current by splitting water into the oxyhydrogen gas, no current path between any electrode plate and the non-conterminous electrode plate, prevented the generation of leakage current, reduced the temperature of electrolytic cell, so do not need as application number 200480040719.2, need on metal shell, settle sink.
