Embodiment 1

[0075] Embodiment 1: When the present invention is applied to the long-term environmental maintenance of motor vehicle gasoline engines, the following sub-steps are carried out successively:

[0076] S1 uses waste detection analyzers and vehicle decoders to analyze vehicle exhaust;

[0077] S2 removes dust from the air filter of the intake system;

[0078] S3 adds a special engine cleaning agent with high adhesion to metal materials to the engine;

[0079] S4 keeps the engine speed at 2200-2500r / min for 20 minutes to clean some carbon deposits and sludge inside the engine;

[0080] The S5 engine runs at full speed for 5 hours, so that the special cleaning agent can clean the oil sludge and carbon deposits inside the engine;

[0081] S6 flameout, wait for the engine to cool down, replace the lubricating oil and oil filter with nano-scale composite alloy lubricating factor;

[0082] S7 After the engine runs normally for 50 hours, open the oil pan to remove the sediment;

Abstract

The invention discloses an engine and a long-acting environment-friendly maintenance method for an air intake and exhaust system. The method comprises the step (1) of tail gas detection and diagnose, the step (2) of environment-friendly maintenance of air intake system, the step (3) of engine combustion chamber environment-friendly maintenance, the step (4) of engine lubricating system environment-friendly maintenance, the step (5) of exhaust system environment-friendly maintenance, and the step (6) of engine oil circuit system environment-friendly maintenance. The method is characterized in that the step (3) of engine combustion chamber environment-friendly maintenance and the step (4) of engine lubricating system environment-friendly maintenance are combined, and detachment-free long-acting environment-friendly maintenance is conducted through special cleaning agents which are high in adhesive force to metal materials; according to the step (6) of engine oil circuit system environment-friendly maintenance, detachment-free long-acting environment-friendly maintenance is conducted through biomass diesel cleaning agents or gasoline cleaning agents. The method has the beneficial effects that the qualified exhaust index of an engine can be kept all the time by using the method for a long time, power is improved remarkably, and 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...
