Description

Diesel engine after fuel injection heating booster

The present invention relates to a diesel engine rear fuel injection warming combustion-supporting device, so that the oil and gas in the device can reach the ignition point spontaneous combustion due to the high temperature, and the foregoing device is especially designed for the exhaust gas exhaust device (tube) of the diesel vehicle.

It is a well-known technique and common knowledge to install a catalytic converter on a conventional diesel exhaust gas exhaust pipe to reduce air pollution. The ceramic filter is used in the catalytic converter. When the exhaust gas passes through the ceramic filter, the carbon particles in the exhaust gas [ C], a gasified carbon [CO], hydrocarbon [HC] is converted into two gasified carbon [CO2] and water [H2O] volatilization, which is "oxidation reaction"; at the same time, nitrogen oxides [NOX) in the exhaust gas is converted It is volatilized by nitrogen [N2] and oxygen [O2], which is a "reduction reaction"; the "oxidation" and "reduction" processes described above can convert the exhaust gas into a non-polluting gas.

At present, diesel vehicles [such as trucks, trailers, garbage trucks, junction cars, tour buses, etc.], in order to solve the black smoke problem, have a catalytic converter connected to the rear end of the exhaust pipe, but the working temperature of the ceramic filter core is Above 350 °C, in order to work properly, in other words, the temperature of the exhaust gas must be converted into a non-polluting gas by means of the ceramic filter in the aforementioned high temperature state, in order to comply with the air environmental standards, while the exhaust temperature of the diesel vehicle is only At about 100~150 °C, the operating temperature of the catalytic converter is not more than 350 °C. Therefore, the exhaust gas is not completely converted through the ceramic filter, which is likely to cause carbon deposition in the ceramic filter core and cause an increase in "back pressure". This will reduce the conversion effect, and it is easy to produce black smoke, which is the origin of the "squid car".

Although some operators try to use the technology used in incinerators, combustion furnaces, etc., that is, before the catalytic converter, an electric heating device (that is, a heater with a plurality of electric heating tubes combined) is provided, and the heating is heated by electric heating. After the temperature of the device is increased to 350 ° C or higher, the catalyst is re-introduced into the catalytic converter for redox, and the ceramic filter can operate normally at the above operating temperature to convert the exhaust gas into a non-polluting gas. This technology is applied to the vehicle, but the implementation In the technical means, it is necessary to have a large air compressor and a 10% power source when the generator is powered to be used as an electric heating device for heat generation.

However, it is impossible to install such a large-scale electric heating device on a diesel car, and there is no such large voltage to supply the electric heating device, and it is even more impossible to set a bioelectric device such as a generator, and there is no large air compressor. After miniaturization, there are more problems with low efficacy, so it is not very applicable.

Therefore, the creator has designed a diesel engine afterburning fuel-assisted combustion-supporting device, which is a "catalyst pre-heating combustion-supporting device", which aims to improve the combustion efficiency of the exhaust gas before entering the catalytic converter for combustion heating. The exhaust gas enters the catalytic converter for redox reduction, and the exhaust gas is converted into a non-polluting gas discharge, and the content thereof is as shown in the following Patent Document 1: a diesel engine after-burning fuel-burning combustion-supporting device, which includes a combination An afterburner behind the exhaust pipe of the engine, a catalytic converter combined with the afterburner, characterized in that: one side edge of the afterburner is combined with an atomization combustion ignition device, and the other side edge is combined A temperature sensing device, the atomization combustion ignition device comprises an atomizing nozzle for generating an appropriate oil-air mixing ratio, and a heating wire burner for generating a resistance to cause the oil and gas to reach a burning point, and the temperature sensing device is displayed with a temperature The controller generates an electrical connection; the front device of the atomizing nozzle includes an oil supply system for supplying diesel fuel to the atomizing nozzle, and an air supply air to the atomizing nozzle a gas supply system; a side edge of the foregoing afterburner is further combined with a supplemental post-combustion air to support the combustion air supply system; and the temperature display controller, the oil supply system, and the air supply system respectively maintain electrical properties with the battery connection.

In the afterburner of Patent Document 1, since the air replenishing system can supplement the air to assist combustion, although the atomized oil and gas can be burned for the first time, there is a distance between the combustion portion and the catalytic converter, and this section There is less air in the distance, so there is not enough to support the problem of subsequent combustion, resulting in incomplete combustion of atomized oil and gas, and it is still easy to produce black smoke and carbon deposits.

Secondly, in Patent Document 1, since the heating wire burner is a high-voltage electric current, the heating wire is caused to have a high temperature so that the oil gas reaches a burning point, but the high-voltage electric current is easy to cause the diesel oil to adhere to the electric rod. The short-circuit condition causes the atomization ignition device to lose its effect. On the other hand, the high-voltage power supply method has a large requirement for electric power and is easy to cause interference to the vehicle, and there are many problems in high-voltage power-on use.

Further, in Patent Document 1, the oil passage supply system includes at least one automatic replenishment a fuel oil cup, a pressure regulating valve for adjusting the oil pressure of the pipeline, a solenoid valve for controlling the oil inlet, and a fuel tank for supplying the oil source; the oil cup is internally provided with a float, and the float is closed by the float or The needle valve of the open fuel inlet; this oil supply system is too complicated and costly, and the stability of the diesel oil level is too high, and it is not suitable for diesel vehicles that move from time to time.

In view of this, how to provide a diesel fuel that can solve the problem of black smoke emissions while being more usable for a long time, not to worry about the problem that the atomized oil and gas combustion is not complete enough, the ignition is easy to short circuit, and the diesel supply is unstable. After the engine is burned, the fuel-burning combustion-supporting device becomes the object of the present invention for improvement.
