In the case of inhomogeneities within the mixture formation rich zones can arise in the combustion chamber that can generate knocking combustion. Various data from publications herrdin sales documentation of engine manufacturers [10] G. Theoretically, the best possible combustion is held to be isochore heat input constant volume combustion ; the lowest degrees of efficiency are given with isobaric heat input constant pressure combustion.

The smaller the methane number, the higher the compression ratio can be chosen in order to get the best conditions also concerning thermodynamics. A “cross flow type” was chosen as the flow concept, where the exhaust gas side is located on the outside of the engine. GE Energy Jenbacher gas engines Austria The con-rods are precisely forged and have an optimal weight. Each crank web has a counterweight attached with 2 bolts to reduce the inertial forces acting upon the bearings.

A further negative aspect is the insufficient stability of the emissions. This site uses cookies. This peak pressure can occur with single-stage supercharging with BMEPs of 2. The KLS 98 analysis unit is also equipped with two knock sensor inputs that are connected with the knock sensors of the respective cylinders.

The actual process of mixing with the combustion air is carried out in a mixer located in front of the compressor. You do not have access to this content. It operates independently of a user’s location or IP address. The pressure-side bearing shells are, like those of Series 3, jeenbacher using the sputter technology and thus offer an optimal reserve of running time.


To ensure low oil consumption over long running periods, a “Schabering” anti-polishing ring is located on the jenbqcher Figure 8. The surfaces of the main bearings and con-rod bearings are inductively hardened, and the fillets have been additionally reinforced for increased safety. This version was tested not only with the new engine but also at several field plants running on both natural gas and biogas.

The direct comparison of laser ignition with conventional spark ignitions, without any measures implemented in favor of laser ignition high compression ratio, high turbulence ratioconsistently shows advantages in the case uenbacher laser ignition. Customize your page view by dragging and repositioning the boxes below.

Pistons of the engine The “wet” cylinder liner is centered in the spacing ring on the outside of the flange. PGES has expertise in adapting engines to work with alternative fuels.

Gas Engines: Jenbacher Gas Engines Efficiency

Figure 19 shows the special designed electrodes. Therefore appropriate attention was paid to the mixture formation.

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. With the same ignition conditions this new combustion concept made it possible to reduce the methane number requirement by In spite of the BMEP of 2.

Besides the relation of the compression ratio, the design of the combustion presents another decisive influence concerning efficiency. 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.

Relationship between compression ratio, type of combustion and degree of efficiency Regarding gas engines, one must also pay attention to the fuel properties knock resistanceas these also restrict the possibilities of the combustion process.


Jenbacher gas engines have always distinguished themselves through their high degrees of efficiency and power densities [2]. Newer Post Older Post Home.

On the basis of experience with Series 3, development was oriented towards ports producing a swirling flow. NOX control concept [1] brought about the worldwide breakthrough in lean-burn engine technology.


Before being released for full serial production it will be tested in constant operation at several pilot plants and adapted for various low heating value gases.

With extension of the Lambda window, in the case of a spark ignition engine with a 2. The roller tappets shown in Figure 4 can be easily demounted in an upward direction. Sign in or create your free personal ASME account. Herdin; Friedrich Gruber; Werner Henkel; Jenbacher gas engines have always distinguished themselves through their high degrees of efficiency and power densities [2].

Some tools below are only available to our subscribers jenabcher users with an online account. To do this, one need only press a button on the visualization unit of “dia.

Lean-burn – Wikipedia While lean-burn gas engines offer higher theoretical thermal efficiencies, Thermal efficiency is better as higher compression ratios are achieved. To apply the strategy of loss reduction consequently, it is thus necessary to ensure valve cross-sections that are as large as possible.

However, hard reality first evinces itself in the customary running times of the CHP plants. Factors jenabcher increase costs are the lower degree of efficiency, greater outlay for maintenance spark plugs, O2 sensors, care of the catalytic converter, etc. On the torsional vibration damper side the engine is closed off by a turbocharger bracket.
