The advantage of jsnbacher crack type is the extremely high dimensional stability of the bearing diameters, with the consequence that socalled oversize con-rods can be avoided after engine overhauls and costs saved.

Learn about subscription and purchase options. Figure 6 shows a con-rod of this type in comparison to the conventional type of con-rod. The crankcase is designed to be very rigid and has a flange bordering on the oil pan.

KLS 98 with the respective knock sensors All information recorded about misfires and knocking are displayed in the customary way on the screen of the “dia. This herdkn comes with the advantage that great heating value differences of the gas cause no problems in engine operation. Biogas – Wikipedia Biogas is produced as landfill gas LFGwhich is produced by the breakdown of Biodegradable waste inside a landfill due to chemical reactions and microbes, or as digested gas, produced inside an anaerobic digester.

The herdiin of lean-burn combustion is based on the proven LEA. Heat balance of the HEC herdi engine Figure The used material is a heat treated 50 CrMo4 Ni V.

The conrod bearings have a diameter of mm. To keep deformations caused by ignition forces in the area of the valve seat rings minimal, a so-called double-deck construction was chosen and dimensioned with the aid of FE calculation methods [3]. The deck of the banks of cylinders does not extend to jenbzcher cylinder head, but these are bolted to the crankcase via a spacing ring. After an intensive development phase, beginning with the end of the year the first pilot engines were delivered to customers.


The considerably faster combustion of the load of 1. This new technology allows faster combustion and a lower methane number requirement of the engine.

Comparison of exhaust gas berdin of Series Figure Jenbacher Herdjn 6 – Bdc. Glauber Gas-Motors – Figure However, hard reality first evinces itself in the customary running times of the CHP plants. No engine from any competing manufacturer has equivalent dimensioning [5, 6, 7]. Anaerobic Digestion – Wikipedia Anaerobic digestion is jenbacger collection of processes by which microorganisms break down biodegradable material in the herdjn of jebbacher.

The important components were dimensioned for the full load of 60, operating hours typical for stationary engines. A cooling water passage has been cast on both sides of the crankcase, the amount of cooling water being dosed through a bore between the lower and upper deck of the cylinder head. Company Overview GE Energy Jenbacher gas engines 4 GE Energy Jenbacher products Specialist for efficient gas engines – Natural gas segment Production and delivery of plants for decentralized energy supply based on natural With the same ignition conditions this new combustion concept made it possible to reduce the methane number requirement by In this regard, Figure 5 shows the load curves in the area of the fillets from the con-rod bearing to the crank web.

Customize your page view by dragging and repositioning the boxes below. A maximum ignition pressure of Environmental concerns have brought energy efficiency and clean technologies to the forefront. A comparison of the improvement potentials of the 2-valve version with the 4-valve version is shown in Figure 3. For assistance or to subscribe, please contact us:. This value is achieved at one fifth of the NOx emissions of a diesel engine without secondary exhaust gas treatment.

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

Regarding bolted cap and rod, FEM hherdin was carried out to optimize structural shapes and the small end redesigned as a stepped variant. Citing articles are presented as examples only. This engine will be available in the product program.

The supply of oil to the joints and rocker levers is through two main oil channel in the crankcase. Pockstaller Systems for Gas Engines jenbahcer.


Theoretically, the best possible combustion is held to be isochore heat input constant volume combustion ; the lowest degrees of efficiency are given with isobaric herdib input constant pressure combustion. Each cylinder head has a combustion chamber window to allow optical recording of the light conditions during combustion.

The big end is diagonally splitted based on the laser grooved method for maintenance and mounting jenbcaher and is produced for the first time for an engine of this size using the crack technology known from the automotive industry. Each crank web has a counterweight attached with 2 bolts to reduce the inertial forces acting upon the bearings. The mixture coming from the compressor is then conducted via a diffusor to the 2stage intercooler, followed by the throttle. This site uses cookies.

Theoretical preparatory work showed clear advantages in the implementation of this approach both with regard to thermodynamics and ejnbacher dimensioning. 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.

The gear for the oil pump and actuation of the cam shaft is located on the flywheel side, the coupling flange serving as the hwrdin of heridn engine. Vienna University of Technology, Vienna, Austria. The most important parameters of the engine are summarized in Table 1.

Figure 21 shows the KLS 98 analysis unit with the respective knock sensors.


The main targets for the new engine were an increase in efficiency and a minimizing of maintenance costs. The advantage of this design is minimal liner deformations and a contribution additionally to less total weight. The roller tappets shown in Figure 4 can be easily demounted in an upward direction.
