Download or read book Heavy-duty Fleet Test Evaluation Of Recycled Engine Coolant written by RA. Frost and published by . This book was released on 1999 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 240 000 mile (386 232 km) fleet test was conducted to evaluate recycled engine coolant against factory fill coolant. The fleet consisted of 12 new Navistar International Model 9600 trucks equipped with Detroit Diesel Series 60 engines. Six of the trucks were drained and filled with the recycled engine coolant that had been recycled by a chemical treatment/filtration/reinhibited process. The other six test trucks contained the factory filled coolant. All the trucks followed the same maintenance practices which included the use of supplemental coolant additives. The trucks were equipped with metal specimen bundles. Metal specimen bundles and coolant samples were periodically removed to monitor the cooling system chemistry. A comparison of the solution chemistry and metal coupon corrosion patterns for the recycled and factory filled coolants is presented and discussed.

Book Synopsis Diesel Engine Coolant Analysis, New Application for Established Instrumentation by : Daniel Anderson
Download or read book Diesel Engine Coolant Analysis, New Application for Established Instrumentation written by Daniel Anderson and published by . This book was released on 1998 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rotating disk electrode (RDE) arc emission spectrometers are used in many commercial, industrial and military laboratories throughout the world to analyze millions of oil and fuel samples each year. In fact, RDE spectrometers have been used exclusively for oil and fuel analysis for so long, that most practitioners have probably forgotten that when RDE spectrometers were first introduced more than 40 years ago, they were also routinely used for aqueous samples. This paper describes recent work to calibrate and modify Rotating Disk Electrode (RDE) arc emission spectrometers for the analysis of engine coolant samples; a mixture of approximately 50% water and 50% glycol. The technique has been shown to be effective for the analysis of wear metals, contamination and supplemental coolant additives in ethylene and propylene glycol. A comparison of results for coolant samples measured by both Inductively Coupled Plasma (ICP) and RDE spectrometers will be presented. The data correlates extremely well on new and relatively clean coolants. However, not surprisingly, RDE results are sometimes higher for samples containing particles larger than a few micrometers. This paper suggests that RDE spectrometers are appropriate, and sometimes preferred, for most types of coolants and certain types of aqueous samples. Actual field data is be presented to support the arguments.

Book Synopsis Comparison of Bench Test Methods to Evaluate Heavy Duty Coolant Thermal Stability by : R. Doug Hudgens
Download or read book Comparison of Bench Test Methods to Evaluate Heavy Duty Coolant Thermal Stability written by R. Doug Hudgens and published by . This book was released on 2007 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past 10 to 15 years have seen a dramatic change in heavy duty coolants and cooling system maintenance practices. Controversy exists about the relative merits of newer organic acid (OAT) coolants and more conventional products, especially in the area of thermal stability. Coolant life has been extended from two years/240 K miles to at least five years/600 K miles. It is not uncommon for the same charge of coolant to remain in the cooling system until engine rebuild. Further, there has been an equally significant increase in the coolant service intervals. Reinhibition of the coolant was once tied to the oil change interval at 15 to 25 K miles. Now this additive addition has been extended in many cases to one year/150 K miles to two years/300 K miles. • Along with these dramatic increases in coolant life and service interval, strategies to reduce exhaust emissions such as EGR have increased and will continue to increase coolant temperatures. Sorting out coolant stability issues in the field is both expensive and time consuming. Further, it is very difficult to control a field test so as to obtain reliable data. In this environment, a bench test method that can quickly simulate high temperature, severe field service conditions is of vital importance. This paper compares four bench test methods as far as their ability to sort out thermal stability issues based on results from five coolants representing different additive packages and glycol qualities.
Book Synopsis Development of a High-Temperature Coolant for Advanced Diesel Engines by : I. S. Rhee
Download or read book Development of a High-Temperature Coolant for Advanced Diesel Engines written by I. S. Rhee and published by . This book was released on 1984 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study sought to develop a high-temperature coolant for future advanced military diesel engines capable of operating at high temperatures (up to 150 C). The desirable coolant for high-temperature application must have a high boiling point, a low freezing point, good thermal properties (specific heat and thermal conductivity) and must be able to protect the various metals of the cooling system and the engine components against corrosion. In order to evaluate the candidate for high-temperature application under laboratory conditions, the simulated service corrosion test, ASTM D-2570 was conducted at 121 C for 1064 h. Also with this corrosion test mock-up, the cavitation-corrosion test was performed using an aluminum water pump at 121 C for 700 h. The antifreezes used in these tests were mixtures of MIL-A-46153 antifreeze and water containing 50, 60, and 80 wt percent ethylene glycol and similar mixtures containing the antifreeze extender additive, MIL-A-53009. Based on simulated service test results, the antifreeze mixtures containing 50, 60, and 80 wt percent ethylene glycol with antifreeze extender additive were found to be acceptable as potential candidates for the future advanced diesel engine operating at 121 C. Among the three candidate coolants, the antifreeze mixture containing 60 wt percent of MIL-A-46153 with antifreeze extender additive proved to be the optimum coolant for high-temperature application (121 C) based on its boiling point, freezing point, and thermal properties and on the results of the simulated service corrosion and cavitation-corrosion tests. Keywords: pH and reserve alkalinity.

Book Synopsis Heavy-Duty Diesel Engine Cavitation Test by : Glen Davis
Download or read book Heavy-Duty Diesel Engine Cavitation Test written by Glen Davis and published by . This book was released on 2007 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to develop a test procedure to evaluate the ability of a heavy-duty diesel engine coolant to provide protection against damage resulting from a phenomenon known as cylinder liner cavitation corrosion. The engine cavitation test procedure was developed by modifying a production OEM diesel engine to consistently produce the operating conditions that accelerate damage from cylinder liner cavitation. The resulting, 250-h test procedure was able to quantify a coolant's ability to protect wet-sleeve cylinder liners from cavitation corrosion. Dozens of coolants were evaluated using this test procedure. The ranking of cylinder liner pit area counts from this procedure's discrimination matrix was in agreement with the ranking of pit area results seen in high-mileage field tests. Conversely, upon investigation, an acceptable correlation could not be established between field test pit area counts and the results from a known bench test. Obtaining results in a few weeks from a short duration procedure such as this can offer a coolant formulator advantages compared to waiting for the completion of a properly conducted field test. This test procedure creates an accelerated, yet realistic level of liner cavitation that ranks protection levels of coolants being evaluated. This ranking or discrimination is often not possible in field testing because the field test is run under mild service conditions or the engine components have little tendency to promote liner pitting. In addition, the difficulty in controlling field tests often yields unusable, inaccurate results. The test procedure was shown to be repeatable within labs and reproducible between labs thus confirming the viability of this test procedure as a useful tool to assess a coolant's ability to protect against cylinder liner cavitation damage. It is recommended that the presently developed test procedure be considered for adoption as an ASTM test method.

Download or read book Heavy Duty Diesel Engine Coolant Technology written by HJ. DeBaun and published by . This book was released on 2007 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant advances have been made in heavy duty diesel engine technology to meet increasingly stringent environmental regulations for emissions. Today's heavy duty diesel engines are being designed with lighter and softer metals, greater turbocharging, increased combustion controls, and new emission reduction equipment. The cooling systems contained in these vehicles are similarly being impacted by smaller designs, new cooling system configurations, and increased usage of lighter, softer metals. Vehicle thermal loads have significantly increased due to increased power densities, higher engine temperatures, and greater metal-coolant fluxes which places greater emphasis on oxidation/thermal stability, and high temperature corrosion protection performance of the coolant. Other operating conditions (coolant flow rates, turbulence, pressure drops, deaeration) are also becoming more severe calling for improved erosion-corrosion protection, cavitation protection, and elastomer, seal, hose compatibility. This paper reviews the changes in heavy duty diesel engine technology and provides information on coolant performance in 2002-4 emission compliant engines. Predictions are also made on future engine technology and next generation engine coolants.

Book Synopsis Component Durability and High Mileage Performance of a Full Carboxylate Coolant in Heavy Duty Diesel (HDD) Engines by : Carmen Ulabarro
Download or read book Component Durability and High Mileage Performance of a Full Carboxylate Coolant in Heavy Duty Diesel (HDD) Engines written by Carmen Ulabarro and published by . This book was released on 2007 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance of a full carboxylate coolant has been demonstrated in engine bench cavitation testing, fleet testing, and post fleet testing coolant corrosion tests. Performance in the proposed ASTM "Heavy Duty Cavitation Test" was established and found to satisfactorily exceed performance limits. Fleet testing of a full carboxylate coolant technology in Class 8 trucks, using Caterpillar C-12 engines demonstrated minimal inhibitor depletion to 400 000 miles under controlled zero coolant top-off conditions with no refortification. In a second fleet, vehicles accumulated high mileages under real world conditions. In this test, Caterpillar 3406E engines were torn down and inspected demonstrating extended corrosion protection and superior component durability to beyond 700 000 miles, without the addition of supplemental coolant additives or extenders. Coolants from these vehicles were removed and tested in the laboratory to verify their extended life properties.
