Product Details

Isuzu Standard Alfin piston for engine 4BE1,Part No.8-94438-989-1A

 

BRAND:  ISUZU
engine NO:  4BE1
Piston DIA: 105.00mm
Piston KH:   56.40mm          (piston KH=compression height)
Piston PIN DIA : 35.00mm

Piston Type

 

Steel-insert piston

Steel-insert piston allows more uniform thermal expansion and tight fitting clearance.

 

ALFIN piston

ALFIN is inserted within the ring grooves when casting. ALFIN is made of special austenitic cast iron. It is tightly bonded metallically to piston body and counteracts the wear in the top ring groove. ALFIN pistons are commonly used in diesel engines.

 

Cooling channel piston

Cooling channel pistons effectively reduce piston body working and groove land temperature under high temperature working condition.

 

One piece casting piston

Compared to common five-pieces casting, one piece casting technology is better in efficiency and appearance, it also reduces casting flaws.

 

Compares piston

The sealing and guiding functions of the piston are separated from one another. The upper part is made of cast iron and the lower part is made of aluminum. The two parts is joined by bolts. The piston can perform with not only maximum strength and heat resistance, but also low wear values and optimum conditions for meeting future emission standards.

 

Forged piston

The forged piston allows smaller cross sections and lower piston weight. This kind of piston is installed primarily in sports car engines and heavy-duty fast-running engines.

 

Piston Technology

 

Tin Coating


Tin is coated by electro analysis or heat dipping at thickness between 0.001 and 0.003mm. Tin is characterized as soft and oil-friendly which improves running-in efficiency of piston and liner. This coating is most commonly used.

 

Graphite Sprayed at Piston Skirt/Graphite Printing
Graphite is characterized as good lubricating, which helps lubricant adhering to coating surface. The coating will reduce friction and scratching. The thickness is between 0.01 and 0.02 mm.

 

Piston roof anodizing
The piston roof is anodized by electro bath, forming thin layer of Al2O3 , This treatment will improve heat resistance (above 500℃), heat conductivity and anti-corrosion,  it helps prevent piston roof burn-up. The thickness is normally 0.02 to 0.05mm. If the thickness increases by 0.01mm, the heat conductivity will decrease by 25%, the roof temperature when running will be lower from 30 to 50℃. Anodizing technology and processing is normally complicated.

 

Piston roof MoS2 Spraying
The function is close to roof anodizing improving heat resistance. The MoS2 is also good at lubrication. (The bigger piston below is piston roof anodizing, the smaller one is MoS2 Spraying)

 

Phosphate
The phosphate is aimed to improve initial running-in performance. The phosphate layer is easy to wear off and helpful to improve running-in.


 

Ceramic Spraying
The treatment performance is similar to anodizing and heat insulation performance is better. The ideal thickness is 0.2 to 0.3mm. When running under high temperature, the ceramic is easy to crack and wear off. It is not commonly used due to high cost
