One of the most important points concerning the combustion of gas in an engine is the controlling of the combustion itself due to the methane number requirement. In this regard, Figure 5 shows the load curves in the area of the fillets from the con-rod bearing to the herdni web.

With 30 years experience in engine development and many years of focus in the gas engine sector, PGES GmbH offers consulting and engine-development support in exactly these areas of expertise. Sign in or create your free personal Herdln account.


Figure 16 shows the heat balance of the first delivered engines. A further negative aspect is the insufficient stability of the emissions. Jenbache concept allows a relatively high degree of swirl with very good flow coefficients mysigma. The KLS 98 analysis unit is also equipped with two knock sensor inputs that are connected with the knock sensors of the respective cylinders.

This concept was termed “oca” optical combustion analysis. The con-rods are precisely forged and have an optimal weight. The concept of jnbacher Tec Jet System is based on an axial valve with closed loop measurement of the gas mass. The components mentioned above are already available for Series 3.

Jenbacher gas engines – St-powergen. A comparison of the improvement potentials of the 2-valve version with the 4-valve version is shown in Figure 3. The cooling water pump is driven electrically and thus the engine can be warmed up prior to startup relatively easily by means of a heater located in the flow of cooling water.


Environmental concerns have brought energy efficiency and clean technologies to the forefront. To apply the strategy of loss reduction consequently, it is thus necessary to ensure valve cross-sections that are as large as possible. This new technology allows faster combustion and a lower methane number requirement of the engine.

In this case too no essential measures were implemented in favor of the exploitation of the potential of laser ignition; however, a minor increase of the compression ratio already allows recognition of the theoretically possible and expected potentials.

Interactive Graphics Video Country-Specific Mortality and Growth Failure in Infancy and Yound Children and Association With Material Stature Use interactive graphics and maps to view and sort country-specific infant and early dhildhood mortality and growth failure data and their association with maternal.

To increase reserves, the diameter of the main bearing was increased from to mm. With the same ignition conditions this new combustion concept made it possible to reduce the methane number requirement by This adaptation pays greater attention to the higher ignition pressures. In the case of inhomogeneities within the mixture formation rich jennbacher can arise in the combustion chamber that can generate knocking combustion.

The conrod bearings have a diameter of mm. These also supply the main bearings as well as the supply channels for the piston cooling oil nozzles. Learn about subscription and purchase options. Moreover, proven constructional features were taken over from Series 3, e. This tuning herdun the efficiency optimum of the engine. Here it must be noted that in terms of utilized possibilities the 2-valve jeenbacher was already in an advanced stage of development.

To be able to fulfill these demands, parallel development of a new type of spark plug was initiated and has been jwnbacher in the meantime.

A particular feature that deserves mention is the automatic ignition voltage control system “monic” monitoring ignition control [10]. The maximum ignition jenbacherr specified for the dimensioning of the engine was The advantage of this design is minimal liner deformations and a contribution additionally to less total weight.

Herdin; Friedrich Gruber; Werner Henkel; Jenbacher gas engines have always distinguished themselves through their high degrees of efficiency and power densities [2].

It allows pressure ratios up to 4.

Gas Engines: Jenbacher Gas Engines Efficiency

Vienna University of Technology, Vienna, Austria. The development of combustion resulted on the basis of direct ignition usual for bore diameters under mm.

Lean-burn – Wikipedia While lean-burn gas engines offer higher theoretical thermal efficiencies, Thermal efficiency is better as higher compression ratios are achieved.

Pockstaller Systems for Gas Engines 1. Therefore appropriate attention was paid to the mixture formation. Two Decades of Optimism. The actual process of mixing with the combustion air is carried out in a mixer located in front of the compressor. Besides the improvement of the housing, the amount and the composition of noble metal were modified to produce a version with greater thermal resistance.

After being transmitted via a light guide to the KLS 98 analysis unit, the signals kenbacher pre-processed into real-time and used for control and monitoring functions.

NOX control concept [1] brought about the worldwide breakthrough in lean-burn engine technology. Anaerobic Digestion – Wikipedia Anaerobic digestion is a collection of processes by which microorganisms break down biodegradable material in the absence of oxygen.
