Abstract

A series of laboratory tests to measure piston ring wear, on a real-time basis, as a function of engine operating conditions (speed, load, and coolant temperature) and oil type, are reported. Two types of tests were performed: one after converting a gasoline engine to run on natural gas, and the other while operating the same engine on gasoline. Piston ring wear was measured using radioactive tracer technology, whereby the small wear particles themselves are monitored as they abrade from the irradiated piston rings and accumulate in the lubrication system. The test data were statistically analyzed and examined on the basis of wear rate as calculated from the instantaneous data showing cumulative wear as a function of test time for a given set of operating conditions. Both independent and synergistic effects were examined. While it was statistically possible to compare wear rates with gasoline and its oil to those for natural gas and its oils, it was not possible to make a distinction with respect to fuel or oil type alone.

Cold start wear performance in methanol and gasoline engines

Book Nautiyal, P; Goetz, W; Goetz, L

Rapid engine wear is one of the most serious problems associated in the commercial exploitation of carburetted, straight methanol spark ignited engines. The existing lubricants are reported to be deficient in the control of cylinder bore and piston ring wear. Whereas, extensive efforts have been made to develop improved lubricants, the problem of increased wear of methanol has not, as yet, been satisfactorily addressed. The various mechanisms proposed for this increased wear have been examined in this paper. It was recognized that the conditions which aggravate the wear of methanol engines are encountered during cold start and warm-up due tomore »« less
Effect of operating conditions on ring wear in a natural-gas engine. Topical report, September 1989-December 1990

Technical Report Crane, M

The report outlines investigations into engine operating conditions that promote piston ring wear on a natural gas engine using a statistically designed test program and sensitive wear monitoring with the radioactive tracer technique. The goal was to identify and quantify the key parameters that promote piston ring wear (i.e., coolant temperature, oil temperature, oil type, engine speed, and peak firing pressure). These results would support research directed at achieving extended ring life on stationary gas engines -- a limiting factor in periods between major engine overhaul.
Wear studies on an automotive gasoline engine using methanol gasoline blends. A study of the effects of variables

Journal Article Nautiyal, P; Pal, M; Zvonow, V - SAE Spec. Publ.; (United States)

This paper presents wear results of the top piston ring for an automotive spark ignited engine using gasoline and methanol blends. The Radiotracer Technique was employed utilising the multichannel analyser. In order to assess the wear process resulting due to each single factor viz. fuel type, engine speed, bhp and the water jacket temperature, investigations were carried out based on a series of statistically designed experiments. The design matrix employed a one half replication of 2/sup 4/ set. The study showed that the speed and load of an engine markedly affect the top ring wear. Use of alcohol blended fuelsmore »« less

Mechanisms of engine wear and engine oil degradation in vehicles using M85 or gasoline

Journal Article Schwartz, S; Mettrick, C - SAE Special Publication

The results of several investigations indicate the extent to which driving cycle, oil formulation, and fuel type (either regular unleaded gasoline or M85) influence the nature and severity of engine-oil degradation and engine damage. Driving cycle greatly influenced mass loss of piston rings and main and connecting rod bearings. For example, short-trip, cold start service with M85 caused 80 times more wear of top piston rings per km of service than was observed in long-trip service with the same oil. The magnitude of engine oil degradation was also documented. Under freeway driving conditions, in which the engine oil warmed completely,more »« less

Fuel component and heteroatom effects on deposits and wear. Interim report, 1 October 1981-30 September 1984

Technical Report Frame, E

The objective of this project was to investigate the effects of fuel heteroatom compounds on diesel-engine performance, particularly engine deposition and wear. This work involved operating a single-cylinder diesel research engine using a highly controlled base fuel (JP-7) which was extremely low in sulfur and nitrogen. The engine lubricant was a synthetic polyalphaolefin material, also free of sulfur and nitrogen. Thus, wear and deposit effects observed during the 60-hour single-cylinder laboratory engine test were directly related to the heteroatom compound added to the base fuel. Through these controlled laboratory engine tests, wear and deposit effects were studied using four differentmore »« less
