The use of tyre pyrolysis oil in diesel engines

Waste Management, 2008
Tests have been carried out to evaluate the performance, emission, and combustion characteristics of a single cylinder direct injection diesel engine fueled with 10%, 30%, and 50% of tyre pyrolysis oil (TPO) blended with diesel fuel (DF). The TPO was derived from waste automobile tyres through vacuum pyrolysis.

Engineering Concepts Useful in Oil Finding

AAPG Bulletin, 1964
This paper discusses first the inter-relationship between relative permeability, capillary pressure, and the vertical distribution of interstitial water in a reservoir. It demonstrates further how this distribution, the resulting position of oil-water or gas-water contacts, and the thickness of the transition zone are affected by the permeability and ...

The Engine Tests of Biodiesel from Used Frying Oil

Energy Sources, 2004
Biodiesel is an environmentally friendly and a renewable alternative diesel fuel that can be used in diesel engines with little or no modification. Used frying oil is one of the raw materials which can be used for biodiesel production. The objective of this study was to investigate the effects of used frying oil originated from biodiesel on engine ...

Tunable oil-water separation using engineered cellulose membranes

Chemosphere
The development of durable and efficient membranes is essential for addressing environmental pollution caused by industrial oil spills and oily wastewater. This study presents a simple surface modification approach using a sol-gel dip-coating technique to fabricate hydrophobic cellulose membranes (CMs) for oil-water separation.

Development of engine oil using palm oil as a base stock for four-stroke engines

Energy, 2010
Abstract The use of palm oil as a base stock for an environmentally friendly lubricant for small four-stroke motorcycle engines is investigated. Palm oil was blended with mineral oil at different compositions to the viscosity requirement of commercial lubricant. A liquid additive package was added to improve the viscosity of the lubricant.

Evaluation of sensor arrays for engine oils using artificial oil alteration

SPIE Proceedings, 2011
With respect to varying operation conditions, only sensors directly installed in the engine can detect the current oil condition hence enabling to get the right time for the oil change. Usually, only one parameter is not sufficient to obtain reliable information about the current oil condition.

Oil and gas extraction: Using engineering simulation

Filtration & Separation, 2009
In the oil and gas industry, specifically the filtration and separation of produced water and sand management generated by oil production, engineering simulation can enhance the operational performance and effectiveness of equipment. In this article, Ahmad H. Haidari of ANSYS, Inc. explains how it can assist with extraction.

Reliability analysis of engine oil using “polygraph approach”

Industrial Lubrication and Tribology, 2008
PurposeThe lubricating oil is a non‐renewable source of energy and its useful life is limited due to deterioration during its usage. It is desirable to maximize its use to conserve this scarce resource. At present, continuation or change of the engine oil is decided, based on the manufacturer's recommendation and experience.

The Use of Oil Engines for Pumping

Journal AWWA, 1916
Internal combustion engines using gasoline as fuel have long been in use for railway water service. The increased consumption of water, necessitating larger pumps and heavier power, together with the increase in the cost of gasoline, has made it necessary to look to a cheaper fuel in the operation of water stations.
