This book was released on 2009-03-10 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, the study of internal combustion engines operation has focused on the steady-state performance. However, the daily driving schedule of automotive and truck engines is inherently related to unsteady conditions. In fact, only a very small portion of a vehicle’s operating pattern is true steady-state, e. g. , when cruising on a motorway. Moreover, the most critical conditions encountered by industrial or marine engines are met during transients too. Unfortunately, the transient operation of turbocharged diesel engines has been associated with slow acceleration rate, hence poor driveability, and overshoot in particulate, gaseous and noise emissions. Despite the relatively large number of published papers, this very important subject has been treated in the past scarcely and only segmentally as regards reference books. Merely two chapters, one in the book Turbocharging the Internal Combustion Engine by N. Watson and M. S. Janota (McMillan Press, 1982) and another one written by D. E. Winterbone in the book The Thermodynamics and Gas Dynamics of Internal Combustion Engines, Vol. II edited by J. H. Horlock and D. E. Winterbone (Clarendon Press, 1986) are dedicated to transient operation. Both books, now out of print, were published a long time ago. Then, it seems reasonable to try to expand on these pioneering works, taking into account the recent technological advances and particularly the global concern about environmental pollution, which has intensified the research on transient (diesel) engine operation, typically through the Transient Cycles certification of new vehicles.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed and highly time resolved experimental measurements were used to characterize the effects of transient operation on the performance of a light duty diesel engine, and to identify the physical processes responsible for transient-specific combustion behavior. The engine response to transient events varied with the size and type of transition and the combustion strategy used, but the underlying processes were similar in all cases. Differences in the response rate of the fuel and air systems caused large variations in the equivalence ratio of the combustion charge during transient events. For moderate to low load conditions, this was primarily due to the discrepancy between the instantaneous intake air flow rate and the composition of the intake charge caused by storage of exhaust gas in the EGR system. This effect was particularly significant for early injection LTC operation due to higher EGR rates and greater dependence of combustion phasing on intake charge composition. Individual combustion cycles during transient events were compared to steady state operation at the same speed and load to quantify the differences in physical conditions. The greatest effect on combustion and emissions was due to differences in intake charge composition, which varied significantly between transient and steady state operation. The response time of the common rail pressure also contributed to transient behavior in situations where the target pressure varied with changes in speed or load. During larger load transitions, thermal inertia of the engine system had a significant effect on emissions, particularly UHC, but did not influence the combustion phasing or heat release rate. The characteristic rates of change of the charge gas, fluid, and physical component temperatures in response to speed or load transitions were much slower than those of other variables such as pressures or flow rates, and were consistent with concurrent variations in engine-out emissions levels. Numerous mechanisms by which thermal inertia could affect emissions formation were identified, including variation of the intake manifold charge gas temperature, in-cylinder heat transfer, and changing physical properties of the fuel.

This book was released on 2015-10-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the combustion engine looks set to remain the dominant energy conversion unit in vehicle powertrains in the medium term, either in combination with electrical components or on its own, attention will need to be paid to continue improving its efficiency in the future. The high development depth of today's combustion engines means that it is becoming increasingly difficult to achieve significant efficiency improvements by simple means. On the search for these improvements, the focus has shifted to inner-engine processes, for instance charge cycles including the charging system, the mixture formation including injection, combustion and kinematic conversion of the energy within the fuel. Our 2nd conference 'Engine processes' aims to offer all developers a platform to discuss the latest technological developments in the field of inner-engine process control, and encourage new paths to be taken. We believe that the program for this conference is a sound foundation for this endeavour. Da der Verbrennungsmotor auch mittelfristig die dominierende Energiewandlungseinheit im Antriebsstrang von Kraftfahrzeugen sein wird, entweder im Verbund mit elektrischen Komponenten oder aber als alleiniger Antrieb, muss der Verbesserung von dessen Wirkungsgrad auch in Zukunft erhebliche Aufmerksamkeit zu Teil werden. Aufgrund der hohen Entwicklungstiefe, die heutige Verbrennungsmotoren aufweisen, wird es immer schwerer, deutliche Wirkungsgradverbesserungen auf einfachem Weg zu erreichen. Auf der Suche nach diesen Verbesserungen rücken die innermotorischen Prozesse immer mehr in den Fokus, hierzu zählen der Ladungswechsel inkl. Aufladesystem, die Gemischbildung inkl. Einspritzung, die Verbrennung sowie die kinematische Wandlung der im Kraftstoff gebundenen Energie. Unsere 2. Tagung „Motorische Prozesse“ soll nun allen Entwicklern als Austauschforum zu neuesten technologischen Entwicklungen auf dem Gebiet der innermotorischen Prozessführung dienen und dazu anregen neue Wege zu beschreiten. Wir sind überzeugt, mit dem vorliegenden Tagungs-Programm hierzu einen sehr guten Beitrag leisten zu können.
