Method of improving combustion efficiency and reducing exhaust emissions by controlling oil volatility in internal combustion engines
First Claim
1. A process for controlling the volatility of recycling lubrication oil in an internal combustion engine so as to improve the combustion efficiency of said engine while concurrently reducing the total hydrocarbons, carbon monoxide and particulates in the exhaust emissions from said engine, said process comprising continuously heating a portion of said recycling lubricating oil in a volatilization chamber at a temperature from 170°
- C. to 260°
C. so as to separate the light volatile fractions in the recycling oil from the remainder of the recycling oil.

Abstract
A method of improving the operating efficiency and reducing certain exhaust emissions in an internal combustion engine is disclosed. By continuously subjecting a portion of recycling engine lubricating oil to heat treatment in the range from 170° C. to 260° C. and preferably the range from 180° C. to 240° C. in a volatilization chamber or the like, an improvement in the fuel consumption as well as a reduction in the total hydrocarbons, carbon dioxide and particulates can be achieved.
