The advantage of this design is minimal liner deformations and a contribution additionally to less total weight. Additionally, measures regarding combustion control in the area of the extended lean-burn limit must also be carried out.

The mixture is passed from this pipe via adapters directly to the cylinder heads. This allows mean pressures up to 2.

Before being released for full serial production it will be tested in constant operation at several pilot plants and adapted for various low heating value gases. All you need to read in the other general jounals BMJ ; We optimize various components to achieve the best performance and efficiency in your engine.

A “cross flow type” was chosen as the flow concept, where the exhaust gas side is located on the outside of the engine. 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. Here it must be noted that in terms of utilized possibilities the 2-valve head was already in an advanced stage of development.

This concept allows a relatively high degree of swirl with very good flow coefficients mysigma.

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. The surfaces jebacher the main bearings and con-rod bearings are inductively hardened, and the fillets have been additionally reinforced for increased safety.


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.

hwrdin Comparison of the pressure curve at a IMEP of 1. 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.

To do this, one need only press a button on the visualization unit of “dia. The crankcase is designed to be very rigid and has a flange bordering on the oil pan.

Moreover, proven constructional features were taken over from Series 3, e. The maximum ignition pressure specified for the dimensioning of the engine was 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.

Knippitsch Leanox Patent Registration number 0 [2] G. Gas engine optimization State of the art solutions.


The components mentioned above are already available for Series 3. Figure 21 shows the KLS 98 analysis unit with the respective knock sensors. The mixture coming from the compressor is then conducted via a diffusor to the 2stage intercooler, followed by the throttle.

To be able to fulfill these demands, parallel development of a new type of spark plug was initiated and has been completed in the meantime. PGES has expertise in adapting engines to work with alternative fuels. 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 low NOx emissions.


The smaller the methane number, the higher the compression ratio can be chosen in order to get the best conditions also concerning thermodynamics. Heat balance of the HEC pilot engine Figure Lean-burn – Wikipedia While lean-burn gas engines offer higher theoretical thermal efficiencies, Thermal efficiency is better as higher compression ratios are achieved. The cooling water pump is driven electrically and thus the engine can be warmed up prior to startup relatively easily by means of a heater located in the flow of cooling water.

The con-rods are precisely forged and have an optimal weight. Two Decades of Optimism. Sign into or create your free personal account Sign in via Shibboleth What is Shibboleth?

Small Power and Equipment – Notes. 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.

Depending on market requirements, a different tuning can also result in higher exhaust gas temperatures with small losses of efficiency.

Regarding bolted cap herdib rod, FEM analysis was carried out to optimize structural shapes and the small end redesigned as a stepped variant. Vienna University of Technology, Vienna, Austria.

Interactive Graphics Video Country-Specific Mortality and Growth Failure in Infancy and Yound Children and Association With Material Stature 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. From the perspective of the development of combustion, if the knock resistance methane number of the fuel is sufficient, BMEPs up to 2.
