Cylinder Head and Glow Plug Caution on 2001-2022 GM Duramax 6.6L Diesel Engines |
|
The AERA Technical Committee offers the following information on a cylinder head and glow plug caution for 2001-2022 GM 6.6L Duramax diesel engines. This caution is expressed for anytime cylinder head work is being done. Through the multiple years of improvements to this engine several cylinder head and glow plug designs have been used for the many different engine models involved. It is important to note that there is not 100% interchangeability of cylinder heads and glow plugs. |

Polymer Coatings for Race Engine Bearings |
|
By Dr. Dmitri Kopeliovich |
|
Most race engines work at very high loads and at high rotation speeds. Combined with the use of low viscosity oils, these conditions cause substantial reduction of the minimum oil film thickness, which separates the bearing and journal surfaces. As a result, metal-to-metal contact occurs frequently. Such contact requires a bearing material with superior antifriction properties. Lack of liquid lubricant (oil) during mixed lubrication [1] may be compensated by a bearing surface consisting of a polymer matrix. Containing solid lubricants distributed in the form of fine particles, this polymer matrix can be applied as a coating to existing bearings to serve as the top layer. |

AERA Tech & Skills Conferences |
|
Everyone in business owes it to themselves and their business to gain knowledge and network with other people within the same industry. AERA understands that traveling to national trade shows to gain knowledge and networking opportunities is very expensive. Therefore, AERA has decided to help by teaming up with a regional host and offer these opportunities to different regions of our country and hopefully closer to your shop. All shops welcome! Need not be an AERA member to attend. |
