Diesel engine catalyst

Abstract

The invention provides a diesel engine catalyst. The common point of the invention with other catalysts is to generate power through the combustion of diesel in oxygen. The invention is characterized in that a gas cavity is additionally arranged behind the turbocharging; an oxygen filter membrane and a nitrogen discharge port are arranged in the gas cavity; the oxygen filter membrane can increase a certain cache space; during the induction stroke of the diesel engine, high pressure oxygen in the cache space is discharged into the device in the cylinder, thereby raising the temperature upper limit by increasing the oxygen concentration and adequately ensuring pressure, temperature and oxygen; and thus, the invention enhances the completeness of combustion and reduces the smoke intensity and hydrocarbons.

Description

technical field [0001] The invention relates to catalytic devices for machinery, especially diesel engines. Background technique [0002] At present, the diesel engines we use are mainly fueled by diesel oil. Usually, high-speed diesel engines use light diesel oil; medium and low-speed diesel engines use light diesel oil or heavy diesel oil. The diesel engine uses a fuel injection pump and a fuel injector to inject fuel into the cylinder at high pressure. The injected fuel is in the form of mist and mixed with air for combustion. Therefore, diesel engines can use heavy or inferior fuels with poor volatility, such as crude oil and residual oil. When burning crude oil and residual oil, in addition to filtering out impurities and water, it is also necessary to preheat and keep the oil supply system warm to reduce viscosity for transportation and injection. Diesel engines can also burn light fuels such as ethanol, gasoline, and methanol if a suitable combustion chamber is used...

AI Technical Summary

Problems solved by technology

At high power output, due to the operation of the power stroke in the diesel engine combustion chamber, the temperature and pressure drop, and there is little oxygen consumption left, so the diesel cannot be completely burned, and smoke and hydrocarbons are produced, and the hydrogen-oxygen bond energy is greater than the carbon-oxygen bond energy. , so there is a large discharge of free carbon, polluting the air, and forming carbon deposits inside, depositing on the spark plug and cylinder, reducing the running-in degree of the piston and cylinder, reducing the life of the internal combustion engine, and greatly increasing fuel consumption

[0005] The use of turbocharging to provide gas supply, on the one hand, can increase the pressure and temperature, and on the other hand, can increase sufficient oxygen, which can reduce free carbon, but the actual use effect is still relatively poor, and the problem can only be partially solved, mainly Because the temperature does not increase significantly, it cannot meet the needs of temperature and pressure reduction during the power stroke
