Problems solved by technology

[0008] However, the use of EGR+DPF technology requires modification of the main engine, complicated calibration, high requirements for fuel and lubricating oil grades, poor fuel economy, easy blockage of the catalytic converter, and high maintenance costs, so most European countries choose NH3-SCR as the mainstream technology route , but the use of NH3-SCR technology requires a large consumption of automobile exhaust treatment fluid, which increases the cost of automobile use, and the consumption of urea, the main component of the treatment fluid, will also cause secondary pollution. In addition, when using NH3-SCR technology, the catalyst has been used for a period of time Finally, because some particles and some metal ions in the exhaust gas adhere to the surface of the catalyst, it will cause the catalyst to fail and affect the catalytic effect, so the existing technology needs further improvement

Abstract

The invention specifically relates to a diesel engine exhaust treating fluid containing nanometer diamondene, belonging to the technical field of automobile exhaust treatment. The diesel engine exhaust treating fluid comprises the following raw materials by weight: 60 to 65 parts of deionized water, 30 to 35 parts of urea, 1 to 5 parts of nanometer diamondene and 0.1 to 2 parts of a surfactant. The diesel engine exhaust treating fluid provided by the invention can reduce the emission of harmful gas in automobile exhaust and is green and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of automobile tail gas treatment, and in particular relates to a diesel engine tail gas treatment liquid containing nano-diamondene and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, automobiles have become a common means of transportation in people's lives, and automobile exhaust pollution has also become a problem of widespread concern in the society. Nowadays, automobiles are mainly divided into gasoline vehicles and diesel vehicles in terms of energy. Gasoline vehicles HC , CO and other harmful gas emissions are dozens of times that of diesel vehicles, so diesel vehicles are loved by people. At present, there are two methods to solve the problem of diesel exhaust emissions, one is EGR+DPF technology, and the other is NH 3 -SCR selective catalytic reduction technology; EGR+DPF technology route is to control the combustion temperature in the c...
