The engine, as a complex assembly of mechanical components, includes the crankshaft and connecting rod mechanism, the valve gear, the transmission mechanism, the fuel supply system, the lubrication system, the cooling system, and the starting system, collectively known as the "three major mechanisms and four major systems." Over 90% of it is made of metal, particularly cast iron and aluminum alloy. From the casting of blanks, forging, stamping, to the process machining, and finally to the assembly of the complete engine, transportation, the cycle is at least one month, involving dozens of machining processes. It uses over 10 different chemicals, including release agents, cutting fluids, lubricants, and coolants. The work of rust and corrosion prevention,

Corrosion protection for typical components such as cylinder blocks, cylinder heads, crankshafts, connecting rods, and the overall engine assembly.

Engine cylinder block and cylinder head rust prevention methods and materials

The engine cylinder is divided into cast iron cylinders and aluminum cylinders with integrated cast iron cylinder liners. The engine cylinder itself has a complex structure, with the cast iron material being relatively porous, having numerous cavities, waterways, and oilways. It is prone to retaining a large amount of cutting fluid and cleaning agents. Additionally, the copper-plated end caps of the channels must be free from copper corrosion.

Recommend the following anti-rust solutions and materials:

·YY-MFS-6081 Multi-metal Water Quality Vapor Corrosion Inhibitor - immersion and spray application. Ideal for rust prevention on carbon steel and cast iron metal parts. Offers excellent rust inhibition, leaving no white spot residue after drying. It does not affect the appearance and is an ideal rust preventive product for steel and iron metal processes, meeting rust prevention and surface quality requirements while maintaining a high level of cleanliness. Can be packaged without drying, providing an extended rust prevention period, greater than...

12 months.

·YY-MSX-9011 is a multi-functional cleaning and rust prevention product. It ensures that the engine is clean, dry, and moisture-free upon delivery to the customer, guaranteeing there is no rust on the engine.

·YY-MFD-5015 VCI Vapor Corrosion Inhibitor protective bags, individually packaged VCI vapor corrosion inhibitor bags or as a whole in multiple canisters

·YY-TFH-6092 Vapour phase rust preventive non-woven fabric or rust preventive sponge, for process rust prevention and rust prevention for cyclic packaging storage up to 6 months

·YY-MGZ-7102 Desiccant Effectively Controls Humidity Inside Packaging

Engine cylinder blocks, engine crankshafts, cast iron brake discs, and cast iron engine cylinder blocks can all be protected from rust using YY-MFD-5015 vapor phase rust prevention bags.

The above rust-preventing materials can all replace the rust-preventing effects of traditional materials, and over time, we have found them particularly suitable for those that are not thoroughly cleaned and dried.

2. Engine Storage Solutions and Rust-Proof Materials

The engine flywheel part can be anti-rust treated with vapor phase anti-rust sponge Y-TFH-6092, followed by applying stretchable anti-rust film YY-MFC-6031.

We can summarize the rust prevention solutions for forgings, especially for cast iron parts prone to rust, as follows:

LAC147H Multi-metal Water-based Rust Preventive Agent, RK101KV Multi-metal Hydrocarbon Phase Rust Preventive Agent, ATR013K+ Water-based Phase Rust Preventive Agent + VCI Phase Rust Preventive Bag + VCI Phase Rust Preventive Paper + Dry

Hero Desiccant combines the following methods:

Vapor Corrosion Inhibitor (VCI) bags + VCI paper, VCI foam + desiccant

2. Vapour Phase Corrosion Inhibitor Packaging + Desiccant

3. Multi-metal Vapour Corrosion Inhibitor + Standard PE Bag
