The power and efficiency upgrade approach for the development of the new Caterpillar 10 MW medium speed gas engine
Increasingly stringent exhaust emission legislation combined with economic pressure to realise the best achievable fuel efficiency, which recently also is expressed as CO2 emission, make natural gas a promising alternative fuel for power generation plants and marine propulsion. This is due to the combined effect of high knock resistance of lean natural gas fuel/air mixtures, which enables high efficiency combustion systems and the lower carbon content in the molecules of natural gas which reduces CO2 emission relative to liquid fuels. Setting the target for a new or updated product was driven by market requirements and availability of new technologies. The targets had to be validated by high level considerations in order to generate a robust project plan and achieve the best possible matching between objectives, resources and timing. As a result a preliminary selection of individual solutions is generated, which is expected to enable the realisation of the specification. In order to assess the consequences of each and every decision made right through to the final product a perfect balance between concise formulation and flexibility had to be found. This paper will present the methodology and highlights (based on simulation, test results and new components design) towards a complex engine power and efficiency upgrade development project based on an already existing engine platform.
