Which ring will cause excessive oil consumption?
Which ring will cause excessive oil consumption?
Piston Ring-pack Deposits and Movement Ring-pack temperatures can range from 195-340 degrees C. Collectively, these conditions can accelerate piston-ring-liner (PRL) wear, impair combustion efficiency, increase blow-by and reduce oil economy (more oil consumption).
How are piston rings related to oil consumption?
It’s true that, with increasing wear, the piston rings become enlarged, as do the piston ring joint gaps. If the cross section of the piston ring is reduced, the ring will cease to function as effectively and will no longer seal properly. An enlarged joint gap and excessive oil consumption are both the result of radial piston ring wear.
How often does a Cummins engine use oil?
The CM 2350 engine has been using alot of oil, like 1 gallon to every 2000 miles, so it could be thats where it’s loosing at. I called Cummins technical support and he said that according to the Cummins that is acceptable usage 1 quart to every 500 miles which i find as ridiculous oil usage. Click to expand…
What is the purpose of a Cummins Service Bulletin?
Service Bulletin Cummins® Engine Oil and Oil Analysis Recommendations Introduction This document outlines the proper application and maintenance of engine oil for engines manufactured by Cummins Inc. The purpose of this Service Bulletin is to update and simplify Cummins Inc. recommendations and guidelines for the end user.
What causes high oil consumption on Cummins ISX15?
So, if you have early life high oil consumption it is NOT carbon packing. It is probably liner lobing and should have the liners replaced. You also want them to replace the pistons to the new “APR” (Anti-Polishing Ring” style piston liner to avoid future Carbon packing issues.
What kind of oil does a Cummins engine use?
Cummins Inc. recommends the use of a high quality SAE 15W40 and SAE 40 engine oil for natural gas and propane engines. The specific performance category of oil recommended is a function of the design of the natural gas engine as outlined below.

How are piston rings worn on a diesel engine?
November 2015; 137 (11): 111503. https://doi.org/10.1115/1.4030290 Piston ring wear is a major factor determining a diesel engine’s life. A ring is subjected to wear between its front face and the cylinder wall as well as at the interfaces between the ring and groove top and bottom flanks.
How does the Centinel system work in a Cummins Engine?
Cummins Inc. has developed the Centinel™ system for continuously replacing the used oil in the engine with fresh oil. This system uses a computer to monitor the engine’s operation and maintains the condition of oil in the engine well within the acceptable range.
