Embodiment 1

[0055] Design a set of vehicle-mounted hydrogen and oxygen generator, operating voltage 12-13.5V, current 20A, tank voltage 2V, electrolyzer gas production 80-150 liters / H, matching with 2.0 engine, the generator is installed in the interior space of the engine compartment of the car , use the electric energy of the car generator, use the cooling fan at the front of the engine to dissipate heat, and use the hydrogen and oxygen gas generated by the electrolysis of pure water for the engine to perform mixed catalytic combustion. Take a Honda car with a displacement of 2.0 in 2003 as an example. The ratio of the amount of oxygen mixture added to the displacement is about 1 / 1000, and the ratio of the amount of hydrogen-oxygen mixture added to the displacement is about 0.5 / 1000 during normal operation (engine speed 2000-3000 rpm). Under certain conditions, the fuel consumption drops from 13 liters / 100 kilometers to less than 10 liters / 100 kilometers, which can save 15-30% of fuel an...

Embodiment 2

[0057] Designed a set of vehicle-mounted hydrogen-oxygen generators for diesel engines. When the operating voltage is 20-30V and the current is 30-50A, the gas production of the electrolyzer is 300-450 liters / H. It is installed on the bus and tested with an exhaust gas analyzer. The NOx content of the vehicle exhaust in the following three states is as follows when the engine is idling and accelerating. The test results show that the NOx emission of the mixed hydrogen and oxygen is far better than the current SCR technology. Through April 2015 to the present, the actual In use, it is found that in addition to reducing the emission of NOx particles, the increase in fuel economy and power is particularly obvious during daily driving. The results are shown in Table 1.

Abstract

The invention discloses a vehicle-mounted oxy-hydrogen generation device mounted on a vehicle for providing hydrogen-oxygen mixed gas to an internal combustion engine. The vehicle-mounted oxy-hydrogen generation device comprises a stainless steel pressure container, an electrolysis tank, a first-grade steam-water separator, a second-grade steam-water separator, an accumulator and a controller. The electrolysis tank uses pure water as electrolyte for electrolysis to generate the hydrogen-oxygen mixed gas. In the device, the gas entering an engine is the hydrogen-oxygen mixed gas, and the hydrogen-oxygen gas separation is not needed; an electric conducting net is in middle of a water guide frame of the electrolysis tank to realize no diaphragm and no intermediate pole, that is, the pole distance of the electrolysis tank is nearly zero, so that the energy consumption is reduced, and the electrolysis efficiency is improved; the pure water can be efficiently electrolyzed; no alkaline substance is evaporated in the electrolysis process, so that the internal combustion engine has no alkaline corrosion; and meanwhile, the electrolysis tank has no diaphragm, so that the service life of the electrolysis tank is largely prolonged.

Description

technical field [0001] The invention relates to electrolysis technology, in particular to a vehicle-mounted hydrogen-oxygen generator. Background technique [0002] In recent years, my country's weather pollution has been very serious, especially in most parts of our country, the time of haze weather has increased, and the public's attention to air quality, especially after the country announced the PM2.5 index, has aroused great attention from all over the country. According to official statistics, the total distribution of PM2.5 emissions, of which the exhaust emissions of automobiles account for 25%, [0003] my country is a big country in the production and use of automobiles, and the number of automobiles is the first in the world. Compared with developed countries, the overall level of automobile engines in my country still has a gap in its emission indicators. Less than 30% of the cars that can meet the National 4 standards need to Reaching the National 5 standard requ...
