Download or read book Analysis of Spark ignition Engine Knock as Seen in Photographs Taken at 200 000 Frames a Second written by Cearcy D. Miller and published by . This book was released on 1946 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: A motion-picture of the development of knock in a spark-ignition engine is presented, which consists of 20 photographs taken at intervals of 5 microseconds, or at a rate of 200,000 photographs a second, with an equivalent wide-open exposure time of 6.4 microseconds for each photograph. A motion picture of a complete combustion process, including the development of knock, taken at the rate of 40,000 photographs a second is also presented to assist the reader in orienting the photographs of the knock development taken at 200,000 frames per second are analyzed and the conclusion is made that the type of knock in the spark-ignition engine involving violent gas vibration originates as a self-propagating disturbance starting at a point in the burning or autoigniting gases and spreading out from that point through the incompletely burned gases at a rate as high as 6800 feet per second, or about twice the speed of sound in the burned gases. Apparent formation of free carbon particles in both the burning and the burned gas is observed within 10 microseconds after passage of the knock disturbance through the gases.

This book was released on 1946 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: A critical review of literature bearing on the autoignition and detonation-wave theories of spark-ignition engine knock and on the nature of gas vibrations associated with combustion and knock results in the conclusion that neither the autoignition theory nor the detonation-wave theory is an adequate explanation of spark-ignition engine knock. A knock theory is proposed, combining the autoignition and detonation-wave theories, introducing the idea that the detonation wave develops in autoignited or afterburning gases, and ascribing comparatively low-pitched heavy knocks to autoignition but high-pitched pinging knocks to detonation waves with the possibility of combinations of the two types of knock.

Available in PDF, EPUB and Kindle. Book excerpt: This paper represents a continuation of the work with the high-speed motion picture camera described before the Semi-Annual Meeting of the Society, June, 1936.1 The experimental observations consist of pictures showing successive positions of the flame at intervals of 2.4 crankshaft deg. during single explosions, and pressure-time records of the same explosions. A method finally is described for sorting out the pressure changes due to combustion from an observed pressure card. When the pressure changes resulting from combustion are summed and put on a percentage basis, it is found that the per cent of pressure rise due to combustion is approximately equal to the per cent of charge burned (by weight) at the corresponding instants in the combustion period. -- SAE website.

This book was released on 2014-02-27 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European Commission is planning to limit emissions under real driving conditions up to high engine loads. RDE (real driving emissions) legislation demands the complete conversion of exhaust gases in the catalytic converter which can only be achieved for spark-ignition engines at lambda=1. High exhaust gas temperatures resulting from late centers of heat release caused by knock can then no longer be limited by mixture enrichment. In addition, higher mean effective pressures are needed to improve the efficiency of SI engines. A strong tendency to knock during stoichiometric combustion in conjunction with high mean effective pressure places exacting demands on the SI engine combustion process. The focus of engine development consequently remains on reducing knock and on avoiding irregular combustion events. In particular, phenomena such as pre-ignition, which is typically observed in downsizing concepts, or extreme knock of the type frequently occurring in highcompression lean-burn concepts, are immense challenges to developers. Contents: Potentials and limits of downsizing | Mega-knock in super-charged gasoline engines interpreted as a localized developing detonation | A contribution to better understanding the pre-ignition phenomenon in highly charged internal combustion engines with direct fuel injection | Minimising autoignition for optimum efficiency in high specific output spark-ignited engines | Reduction in knocking intensity of an SI engine by in-cylinder temperature stratification | New approach to the determination of knock onset | Cylinder pressure-based knock detection – challenges in cylinder pressure indication and application in a new engine-based fuel test method | Irregular combustion: development and calibration of highly boosted SI engines | Optically diagnosing combustion anomalies as part of designing the combustion process | Using surface thermocouples and light conductor measurements to examine the thermal load on a gasoline engine’s components during knocking engine operation | Comparative analysis of low-speed pre-ignition phenomena in SI gasoline and dual fuel diesel-methane engines | LEC-GPN – a new Index for assessing the knock behavior of gaseous fuels for large engines | A statistical modeling approach with detailed chemical kinetics for use in 3DCFD engine knock predictions | Investigation on knocking combustion with reaction kinetics for a turbocharged SIDI engine | Knocking simulation at Mercedes-Benz – application in series production development | The DELTA knocking control – the necessary paradigm shift for engines with high power density | Artificial Intelligence for knock detection | Knock detection strategies based on engine acoustic emission analysis | Continental’s pre-ignition and glow ignition function – detection and avoidance of irregular combustions | Pre-ignition analysis on a turbocharged gasoline engine with direct injection | Knock and irregular combustion – challenges for the new turbocharged, highperformance four-cylinder AMG engine | Simulations and experimental investigations of intermittent pre-ignition series in a turbocharged DISI engine Target group: This book addresses engine developers working for car manufacturers and suppliers. With regard to knocking combustion in spark-ignition engines – irregular combustion – it provides an overview of thermodynamic principals, approaches to measurement and computation together with current trends for mass-production development.
