Problems solved by technology

Due to the lack of precious metal resources in my country and the current composition of motor vehicle fuel oil, pure precious metal catalysts cannot meet the requirements of the domestic automobile exhaust purification market.
At present, the country has not promulgated the standards for diesel detergents. Most of the diesel detergents produced according to enterprise standards have the same effect. The main functions are cleaning parts, improving power, saving fuel, and reducing emissions. Although they have cleaning and energy-saving performances, they do not have The effects of continuous catalysis, cracking, and enhanced combustion, but the cleaning effect is not ideal

Abstract

The invention provides an environment-friendly type diesel catalysis detersive for cleaning emission of diesel automobiles, which is prepared from cleaning and dispersing agent, anti-oxidant, alkyl nitrite or isopropyl nitrate and high grade plane kerosene through high-shearing mixing and emulsion process. The agent can improve combustion efficiency according to the combustion conditions.

Description

technical field [0001] The invention relates to a diesel catalytic cleaner, which belongs to the technical field of petrochemical industry. Background technique [0002] Due to its low cost and strong power, diesel is widely used as engine fuel for vehicles, ships, and various agricultural, construction, mining, and military machinery and equipment. However, due to the quality characteristics of diesel oil itself and the high-pressure injection combustion method, the phenomenon of black smoke emission from diesel engines during operation is quite serious, which has caused serious pollution to the living environment of human beings and wasted precious resources at the same time. How to solve the problem of serious pollution from diesel engine emissions It has become a hot topic worldwide. The existing automobile exhaust purification catalysts on the Chinese market are basically particle-filled exhaust muffler type (filter type), and there are generally three types according ...
