Therefore appropriate attention was paid to the mixture formation. Jenbacher gas engines have always distinguished themselves through their high degrees of efficiency and power densities [2]. Related Content Customize your page view by dragging and repositioning the boxes below. In the case of inhomogeneities within the mixture formation rich zones can arise in the combustion chamber that can generate knocking combustion.

The mixture coming from the compressor is then conducted via a diffusor to the 2stage intercooler, followed by the throttle.

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. To do this, one need only press a button on the visualization unit of “dia. L Natural gas 1. 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 – St-powergen.

Anaerobic Digestion – Wikipedia Anaerobic digestion is a collection of processes by which microorganisms break down biodegradable material in the absence of oxygen. 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.

At that time a main overhoul is necessary. Pistons of the engine The “wet” cylinder liner is centered in the spacing ring on the outside of the flange. Figure 16 shows the heat balance of the first delivered engines.

With this concept, oil consumption can be guaranteed in a range of 0.

This concept comes with the advantage that great heating value differences of the gas cause no problems in engine operation. Factors that increase costs are the lower degree of efficiency, greater outlay for maintenance spark plugs, O2 sensors, care of the catalytic converter, etc. Each crank web has a counterweight attached with 2 bolts to reduce the inertial forces acting upon the bearings. The surfaces of the main bearings and con-rod bearings are inductively hardened, and the fillets have been additionally reinforced for increased safety.

Regarding bolted cap and rod, FEM analysis was carried out to optimize structural shapes and the small end redesigned as a stepped variant. Knippitsch Leanox Jennbacher Registration number 0 [2] G. The advantage of the 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.

This jjenbacher plug is designated as JW P4.

Here it must be noted that in terms of utilized possibilities the 2-valve head was already in an advanced stage of development.

To apply the strategy of loss reduction consequently, it is thus necessary to ensure valve cross-sections that are as large as possible. Utilizing this concept means that in future calorically weak gases can also be burned with high degrees of efficiency.

This biogas can be used directly as fuel, in combined heat and power gas engines or upgraded to natural gas-quality biomethane. It allows pressure ratios up to 4. As a result, besides its combustion chamber window, each cylinder has a knock sensor used for cylinder-specific control of ignition energy and knocking.

A further negative aspect is the insufficient stability of the emissions. All control interventions can be carried out in a very short time ms and all interventions are done via a CAN bus supervised from the central control unit dia. The actually possible process of combustion Seiliger cycle lies between both curves; jenbachwr any case, for good degrees of efficiency one should strive for as large a constant volume portion as possible.

The young and motivated team supports him with fresh spirit and herxin ideas, using one of the latest design software. The smaller the methane number, the higher the compression ratio can be chosen in order to get the best conditions also concerning thermodynamics. The maximum ignition pressure specified for the dimensioning of the engine was The actual process of mixing with the combustion air is carried out in a mixer located in front of the compressor.

For that jenbacherr, the following primary objectives were fixed: The components mentioned above are already available for Series 3.

The upper water jacket is separated from the lower water jacket by means of a conical partition, the passage of cooling water being effected by bore holes in the wall between the valves. Visualization of actual ignition voltage values on the dia. 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.

You do not have access to this content. Herdin; Friedrich Gruber; Werner Henkel; Jenbacher gas engines have always distinguished themselves through their high degrees of efficiency and power densities [2]. One of the essential criteria for lean gas engines is as homogenous a mixture as possible.

NOX control concept [1] brought about the worldwide breakthrough in lean-burn engine technology. Vienna University of Technology, Vienna, Austria.
