This peak pressure can occur with single-stage supercharging with BMEPs of 2. We optimize various components to achieve the best performance and efficiency in your engine. This engine will be available in the product program. One aspect concentrated on ienbacher development was in the area of optimal mounting and service-friendliness.

Figure 7 shows a version of a piston used for tests. External sites have access to all information though direct communication with “dia.

To do this, one need only press a button on the visualization unit of “dia. This version was tested not only with the new engine but also at several field plants running on both natural gas and biogas. The most important parameters of the engine are summarized in Table 1.

As a result, besides its combustion chamber window, each cylinder has a knock sensor used for cylinder-specific control of ignition energy and knocking.


In the mid’s the development of the LEA. However, hard reality first evinces itself in the customary running times of the CHP plants. Conversely, in the event of the utilization of lean-burn combustion, appreciably more energy must be provided. Environmental concerns have brought energy efficiency and clean technologies to the forefront. As a potential solution, one selected the known version of the combination of a tangential port with a spiral port.


Gas Engines: Jenbacher Gas Engines Efficiency

It was even possible to increase the bore-specific flow coefficient of the exhaust port by Jenbacher gas engines have always distinguished themselves through their high degrees of efficiency and power densities [2]. This biogas can be used directly as fuel, in combined heat and power gas engines or upgraded to natural gas-quality biomethane.

GE Energy Jenbacher gas engines Austria The considerably faster combustion of the load of 1. Shibboleth is an access management service that provides single sign-on protected resources.

The con-rods are precisely forged and have an optimal weight. Professional Gas Engine Solutions 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.

For herdi or to subscribe, please contact us: All cylinders therefore have the same cooling conditions and no temperature gradients occur from the front to the rear cylinders of the cylinder engine.

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.

The conrod bearings have a diameter of mm. Using alternative and efficient concepts of newest technology, PGES is able to support the optimization of existing sources or developing new concepts to generate maximum output with highest environmental sustainability.

The gear for the oil pump and actuation of the cam shaft is located on the flywheel side, the coupling flange serving as the end of the engine. Newly developed control and monitoring strategies, as well as long-distance data transmission, allow preventive maintenance measures and an additional improvement of reliability.

With this concept, oil consumption can be guaranteed in a range of 0. Newer Post Older Post Home. Pistons of the engine The “wet” cylinder liner is centered in the spacing ring on the outside of the flange.

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.


Gas engine optimization State of the art solutions. 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.

Jrnbacher control of lean-burn combustion is based on the proven LEA. Customize your page view by dragging and repositioning the boxes below.

The pressure-side bearing shells are, like those of Series 3, produced using the sputter technology and thus offer an optimal reserve of running time. On the torsional vibration damper side the engine is closed off by a turbocharger bracket. No engine from any competing manufacturer has equivalent dimensioning [5, 6, herdjn.

You do not have access to this content. One of the essential criteria for lean gas engines is as homogenous a mixture as possible. In particular, the operating costs of stoichiometrically run engines besides the higher specific procurement costs are considerably more expensive in comparison to lean-burn engines. Here it must be noted that in terms of utilized possibilities the 2-valve head was already in an advanced stage of development.

This new technology allows faster combustion and a lower methane number requirement of the engine. This adaptation pays greater attention to the higher ignition pressures. The structure of the crankshaft was calculated in detail using the FE method and optimized for the safety factors required for stationary 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. Jenbacher Type 6 – Bdc.
