Embodiment 1

[0077] 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:

[0078] S1 Carry out exhaust gas analysis of vehicles with waste detection analyzers and vehicle decoders;

[0079] S2 to remove dust from the air filter of the intake system;

[0080] S3 Add a special engine cleaning agent with high adhesion to metal materials to the engine;

[0081] S4 Keep the engine speed at 2200-2500 r / min for 20 minutes to clean some carbon deposits and sludge inside the engine;

[0082] 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;

[0083] S6 Turn off the engine, wait for the engine to cool down, replace the lubricating oil and oil filter with nano-scale composite alloy lubricating factor;

[0084] S7 After the engine runs normally for 50 hours, open the oil pan t...

Embodiment 2

[0090] Embodiment 2: When the present invention is applied to the long-term environmental maintenance of motor vehicle diesel engines, the following sub-steps are carried out in sequence:

[0091] S1 Carry out exhaust gas analysis of vehicles with waste detection analyzers and vehicle decoders;

[0092] S2 to remove dust from the air filter of the intake system;

[0093] S3 Add a special engine cleaning agent with high adhesion to metal materials to the engine;

[0094] S4 Keep the engine speed at 2200-2500 r / min for 20 minutes to clean some carbon deposits and sludge inside the engine;

[0095] 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;

[0096] S6 Turn off the engine, wait for the engine to cool down, replace the lubricating oil and oil filter with nano-scale composite alloy lubricating factor;

[0097] S7 After the engine runs normally for 50 hours, open the oil pan to r...

Abstract

The invention discloses a long-term environment-friendly maintenance method for an engine and an intake and exhaust system. The method includes an exhausting gas detecting and diagnosing step (1), an environment-friendly intake system maintenance step (2), an environment-friendly engine combustion chamber maintenance step (3), an environment-friendly engine lubrication system maintenance step (4), an environment-friendly exhaust system maintenance step (5), and an environment-friendly engine oil-way system maintenance step (6). The method is characterized in that the environment-friendly engine combustion chamber maintenance step (3) and the environment-friendly engine lubrication system maintenance step (4) are combined, and disassembling-free long-term environment-friendly maintenance is performed by adopting special engine cleaning agent having high adhesion for metal materials; according to the environment-friendly engine oil-way system maintenance step (6), disassembling-free long-term environment-friendly maintenance is performed by adopting biomass diesel cleaning agent or gasoline cleaning agent. The long-term environment-friendly maintenance method has the advantages that the engine can be maintained to be consistent with qualified emissions targets by utilizing the method for long time, power can be optimized significantly, and fuel consumption can be saved by about 10%.

Description

technical field [0001] The invention relates to the technical field of engine resources and environment, in particular to a long-term environmental maintenance method for an engine and an intake and exhaust system. Background technique [0002] 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. [0003] At present, the technologies for the purification of automobile exhaust emissions in the world are as follows: [0004] 1. Change the energy used by the car or increase the effective mechanical power (mechanical friction modifier, green alternative fuel, electric power); [0005]...
