After an intensive development phase, beginning with the end of the year the first pilot engines were delivered to customers.

Two Decades of Optimism. On hervin torsional vibration damper side the engine is closed off by a turbocharger bracket. Besides the relation of the compression ratio, the design of the combustion presents another decisive influence concerning efficiency. The concept of the Tec Jet System is based on an axial valve with closed loop measurement of the gas mass.

Conversely, in the event of the utilization of lean-burn combustion, appreciably more energy must be provided. To do this, one need only press a button on the visualization unit of “dia.

Gas Engines: Jenbacher Gas Engines Efficiency

Some tools below are only available to our subscribers or users with an henbacher account. The deck of the banks of cylinders does not extend to the cylinder head, but these are bolted to the crankcase via a spacing ring.

Technical Specification – Cogeneration.

Factors that increase costs ehrdin the lower degree of efficiency, greater outlay for maintenance spark plugs, O2 sensors, care of the catalytic converter, etc. Figure 19 shows the special designed electrodes.


This concept was termed “oca” optical combustion analysis. Herdin; Friedrich Gruber; Werner Henkel; Jenbacher herddin engines have always distinguished themselves through their high degrees of efficiency and power densities [2]. Here it must be noted that in terms of utilized possibilities the 2-valve head was already in an advanced stage of development. For assistance or to subscribe, please contact us:.

For that reason, the following primary objectives were fixed: This allows mean pressures up to 2. In spite of the BMEP of 2. Principally, the temperature load on the HEC piston due to the smaller Lambda is, despite the higher BMEP, perhaps equal to or somewhat less compared with the present state of Series 3.

Jenbacher Type 6 – Bdc. This value is achieved at one fifth of the NOx emissions of a diesel engine without secondary exhaust gas treatment. The development of combustion resulted on the basis of direct ignition usual for bore diameters under mm. The principal function is shown in Figure Environmental concerns have brought energy efficiency and clean technologies to the forefront. 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.

Only then is it possible to ensure optimal values for burning durations and the variation coefficient. The actual process of mixing with the combustion air is carried out in a mixer located in front of the compressor.

In this regard Figure 18 shows a comparison of the HEC engine to the competition as well as to several diesel engines [9]. A further negative aspect is the insufficient stability of the emissions.


Besides the improvement of the housing, the amount and the composition of noble metal were modified to produce a version with greater thermal resistance.

Therefore appropriate attention was paid to the mixture formation. As a result, besides its combustion chamber window, each cylinder has a knock sensor used for cylinder-specific control of ignition energy and knocking.

The actually possible process of combustion Ejnbacher cycle lies between both curves; in any case, for good degrees of efficiency one should strive for as large a constant volume portion as possible. The smaller the methane number, the higher the compression ratio can be chosen in order to get the best conditions also concerning thermodynamics.


Citing articles are presented as examples only. The concept of “monic” allows an online display of all ignition voltage values and thus a monitoring of the condition of the spark plugs. The mixture is passed from this pipe via adapters directly to the cylinder heads. This tuning attains the efficiency optimum of the engine. 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 advantage of this design is minimal liner deformations and a contribution additionally to less total weight. The young and motivated team supports him with fresh spirit and future-oriented ideas, using one of the latest design software.

The conrod bearings have a diameter of mm.
