Title: Kevin R. Calstrom: Innovator in Engine Lubrication Monitoring

Introduction

Kevin R. Calstrom is a notable inventor based in Fort Wayne, IN (US). He has made significant contributions to the field of engine lubrication monitoring, holding a total of 2 patents. His innovative methods aim to enhance the efficiency and reliability of internal combustion engines.

Latest Patents

One of Kevin's latest patents is a method for monitoring engine lubricant condition. This method generates indicators relating to the condition of lubricating oil in an internal combustion engine. A set of variables relating to the operation of the engine serves as proxy variables for brake mean effective pressure. The operation of the engine is monitored to develop values for these proxy variables. Soot is added to the lubricating oil based on the developed values, allowing for an estimate of total soot in the oil. Additionally, the temperature of the lubricating oil is periodically monitored, and a history of these measurements is maintained. This data helps generate an estimate of the shear of the lubricating oil. The accumulated estimate of soot indicates the distance remaining until the oil becomes unsuitable for use. Similarly, the estimated shear provides a distance until the oil needs to be replaced. Other factors, such as the dielectric coefficient of the lubricating oil and total cylinder firing events, may also be monitored to determine when an oil change is required.
