Gas Engines: Jenbacher Gas Engines Efficiency

This concept allows a relatively high degree of swirl with very good flow coefficients mysigma. Shibboleth is an access management service that provides single sign-on protected resources. To ensure low oil consumption over long running periods, a “Schabering” anti-polishing ring is located on the inside Figure 8. This tuning attains the efficiency optimum of the engine.

This site uses cookies. The simplication of service and maintenance tasks is rounded off by “hermes”, the Jenbacher long-distance data transmission concept.

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

It was even possible to increase the bore-specific flow coefficient of the exhaust port by A comparison of the improvement potentials of the 2-valve version with the 4-valve version is shown in Figure 3. The spark plug is located centrally in a very jenbaacher cooled sleeve.

The advantage of this design is minimal liner deformations and a contribution additionally to less total weight.

Regarding stoichiometric conditions, from the viewpoint of the researchers working jointly on the project it is possible to reduce the energy to less than 1 mJ. In this regard Figure 18 shows a comparison of the HEC engine to the competition as well as to several diesel engines [9].

This engine will be available in the product program.

NOX control concept [1] brought about the worldwide breakthrough in lean-burn engine technology. Classes F 6 — F 9.

Newer Post Older Post Home. For assistance or to subscribe, please contact us: The following types of piston rings are used: On the basis of experience with Series 3, development was oriented towards ports producing a swirling flow. It replaces the multiple user names and passwords necessary to access subscription-based content with a single user name and password that can be entered once per session.

The con-rods are precisely forged and have an optimal weight. Vienna University of Technology, Vienna, Austria. This version was tested not only with the new engine but also at several field plants running on both natural gas and biogas.

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. Furthermore, the specific power density of the new engine – The concept of the Tec Jet System is based on an axial valve with closed loop measurement of the gas mass.

From the perspective of the development of combustion, if the knock resistance methane number of the fuel is sufficient, BMEPs up to 2.

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. The existing 2-valve head showed increasing losses especially with the high mass flow rates of the lean-burn engine concept from BMEPs of 1. This concept was termed “oca” optical combustion analysis. Principally, the temperature load on the HEC piston due to the smaller Lambda is, despite jenbachee higher BMEP, perhaps equal to or hefdin less compared with the present state of Series 3.

This biogas can be used directly as fuel, in combined heat and power gas engines or upgraded to natural gas-quality biomethane. A “cross flow type” was chosen as the flow concept, where the exhaust gas side is located on the outside of the engine.

Jenbacher gas engines have always distinguished themselves through their high degrees of efficiency and power densities [2]. Alongside this requirement, it is also necessary to produce the desired flow conditions in the combustion chamber through the intake ports. Figure 10 shows the influence of the combustion duration with three different compression ratios compared with the theoretically found indicated degrees of efficiency.

Customize your page view by dragging and repositioning the boxes below. 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.

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

THE NEW HIGH EFFICIENCY MW ENGINE OF JENBACHER AG

The engine has only one camshaft located centrally in the crankcase that is gear driven on the flywheel side. As a potential solution, one selected the known version of the combination of a tangential port with a spiral port. Jenbacher Type 6 – Bdc. External sites have access to all information though direct communication with “dia.

The focus in research year 05 was on the optimization of optical coupling and minimization of laser energy especially in connection with very lean combustion and with high exhaust gas recirculation rates for jenbachdr NOx emissions. Learn about subscription and purchase options. The deck of the herdon of cylinders does not extend to the cylinder head, but these are bolted to the crankcase via a spacing ring.

Figure 6 shows a con-rod of this type in comparison to the conventional type of con-rod. 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.
