Abstract

The invention discloses a long-acting environment-friendly maintenance method for an engine, an air intake system and an exhaust system. The method includes a tail gas detection and diagnosis step (1), an air intake system environment-friendly maintenance step (2), an engine combustion chamber environment-friendly maintenance step (3), an engine lubrication system environment-friendly maintenance step (4), an exhaust system environment-friendly maintenance step (5) and an engine oil way system environment-friendly maintenance step (6). The method is characterized in that the engine combustion chamber environment-friendly maintenance step (3) and the engine lubrication system environment-friendly maintenance step (4) are combined, non-dismantling long-acting environment-friendly maintenance is conducted through a special engine cleaning agent having high adhesive force to metal materials, and as for the engine oil way system environment-friendly maintenance step (6), a biomass diesel oil cleaning agent or a gasoline cleaning agent is adopted for non-dismantling long-acting environment-friendly maintenance. The long-acting environment-friendly maintenance method for the engine, the air intake system and the exhaust system has the beneficial effects that the emission index of the engine can be kept qualified all the time through long-term implementation of the method, the power is obviously improved, and the oil consumption can be reduced by about 10%.

Description

technical field [0001] The invention relates to the technical field of resources and the environment of an engine, in particular to an engine and an intake and exhaust system [0002] A long-term environmental protection method. Background technique [0003] According to the survey results of the 2012 "Annual Report on the Prevention and Control of Motor Vehicle Pollution in China" by the Ministry of Environmental Protection, motor vehicles have become one of the main sources of energy consumption, air pollution and greenhouse gas emissions in my country. Motor vehicle pollution is becoming increasingly serious and has become one of the most prominent and urgent problems of the atmospheric environment. [0004] At present, the technologies for the purification of automobile exhaust emissions in the world are as follows: [0005] 1. Change the energy used by the car or increase the effective mechanical power (mechanical friction modifier, green alternative fuel, electric po...
