The following types of piston rings are used: Jenbacher gas engines – St-powergen. Each crank web has a counterweight attached with 2 bolts to reduce the inertial forces acting upon the bearings.

Figure 19 shows the special designed electrodes. One of the essential criteria for lean gas engines is as homogenous a mixture as possible.


It operates independently of a user’s location or IP address. In this regard, Figure 5 shows the load curves in the area of the fillets from the con-rod bearing to the crank web. As a result, besides its combustion chamber window, each cylinder has a knock sensor used for cylinder-specific control of ignition energy and knocking.

Conversely, in the event of the utilization of lean-burn combustion, appreciably more energy must be provided. Figure 6 shows a jenbacuer of this type in comparison to the conventional type of con-rod. Regarding bolted cap and rod, FEM analysis was carried out to optimize structural shapes and the small end redesigned as a stepped variant.

It allows pressure ratios up to 4. After being transmitted via a light guide to the KLS 98 analysis unit, the signals are pre-processed into real-time and used for control and monitoring functions. You either do not have a subscription or your subscription has expired.

A particular feature that deserves mention is the automatic ignition voltage control system “monic” monitoring ignition control [10]. The crankcase is designed to be very rigid and has a flange bordering on the oil pan.

Environmental concerns have brought energy efficiency and clean technologies to the forefront. Theoretical herdim work showed clear advantages in the implementation of this approach both with regard to thermodynamics jenbacherr component dimensioning.

Newly developed control and monitoring strategies, as well as long-distance data transmission, allow preventive maintenance measures and an additional improvement of reliability. 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 of laser ignition.

Gas engine performance measurements First step to improve your engine. With this concept, oil consumption can be guaranteed in a range of 0. The con-rods jenbscher precisely forged and have an optimal weight. Efficiency and specific output GE Jenbacher gas engines can provide high flexibility This version was tested not only with the new engine but also at several field plants running on both natural gas and biogas.

For that reason, the hegdin primary objectives were fixed: 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.

Figure 16 shows the heat balance of the first delivered engines. Smart cogeneration plants with high efficient gas engines Author The figure below shows the development and output over time of the Jenbacher type 6 gas engine family.

To do this, one need only press a button on the visualization unit of “dia. 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 In spite of the BMEP of 2.

To apply the strategy of loss reduction consequently, it is thus necessary to ensure valve cross-sections that are as large as possible.

The big end is diagonally splitted based on the laser grooved method for maintenance and mounting reasons and is produced for the first time for an engine of this size using the crack technology known from the automotive jenbacer. As a potential solution, one selected the known version of the combination of a tangential port with a spiral port.


For diesel engines this value is absolutely top-notch, but is connected with about fivefold higher NOx emissions. Sign in or create your free personal ASME account. A comparison of the improvement potentials of the 2-valve version with the 4-valve version is shown in Figure 3. The smaller the methane number, the higher the compression ratio can be chosen in order to get the best conditions also concerning thermodynamics. This new technology allows faster combustion and a lower methane number requirement of the engine.

With extension of the Lambda window, in the case of a spark ignition engine with a 2. This tuning attains the efficiency optimum of the engine. After an intensive development phase, herdjn with the end of the year jerdin first pilot engines were delivered to customers.

In this regard Figure 18 shows a comparison of the HEC engine to the competition as well as to several diesel engines [9].

The mixture is passed from this pipe via adapters directly jembacher the cylinder heads. Comparison of the pressure curve at a IMEP of 1. We optimize various components to achieve the best performance and efficiency in your engine. Actuation of the valves is by means of roller tappets, push rods, rocker uenbacher and valve bridges.

With the same ignition conditions this new combustion concept made it possible to reduce the methane number requirement by The control of lean-burn combustion is based on the proven LEA. The mixture coming from the compressor is then conducted via a diffusor to the jengacher intercooler, followed by the throttle. Alongside this requirement, it is also necessary to produce the desired flow conditions in the combustion chamber through the intake ports.
