Unscavenged prechamber ignition has recently been developed at LENI-EPFL to reduce the emissions from cogeneration spark ignition gas engines (natural gas and biogas) within the Swiss Motor project supported by the Federal Office of Energy. Prechambers fit ...
The object of this work is to test the unscavenged prechamber ignition system on a 150 kW cogeneration engine feed with biogas. The engine performances in term of fuel conversion efficiency are observed and the reduction potential f the exhaust emissions b ...
The work accomplished during the second period of the project mainly focused on the experimental evaluation of the prechamber system comparing its performance regarding emissions and efficiency to standard spark ignition mode. Further instrumentation of th ...
A new concept of small hybrid solar power system (HSPS) has been successfully demonstrated in the context of a project called SPS (Solar Power System). This plant integrates two rows of solar collectors, two superposed Organic Rankine Cycles (ORC) each equ ...
Directory services are a genuine constituent of any distributed architecture which facilitate binding attributes to names and then querying this information, that is, announcing and discovering resources. In such contexts, especially in a business environm ...
The increasing interest in new software engineering technologies for application integration such as Service Oriented Computing and Service Orchestration has resulted in a proliferation of workflow management systems as the underlying representation and ex ...
This paper describes the implementation of the hard computational kernels required for the baseband (BB) processing of a 2×2 multiple-input multiple-output (MIMO)-OFDM receiver on a design-framework for application specific processors. The employed low-com ...
This work is part of ongoing research on stationary natural gas engines equipped with unscavanged prechambers. Spark ignition inside the prechamber has been successfully proven with natural gas as well as biogas, reducing emissions while keeping good effic ...
Unscavanged prechamber ignition has been developed at the Laboratory of Industrial Energy Systems to reduce the emissions from cogeneration spark ignition gas engines, operating with both natural gas and biogas. Demonstration has been made that a lean burn ...
