If it is to achieve the same flow pattern, the rotor in a MEMS turbine has to spin a good deal faster than that in a conventional jet engine.The fuel combustion process has also posed a challenge for the designers.
This index strongly influences the performance of the engine during fuel combustion and exhaust emission.
Incidentally, the H2 is not Kawasaki's first foray into forced induction, which feeds large quantities of air into the engine to optimise fuel combustion and boost power.
Decades later, after the practical demonstration of motorjets and turbojets, Coandă began to tell various conflicting stories about how his early experiments were precursors to the jet, even that his turbo-propulseur was the first motorjet engine complete with fuel combustion in the air stream.
These engines are known as dual fuel combustion engines, i.e. they use conventional Diesel fuel and a gaseous fuel as well.
As an internal combustion engine fuel, hydrogen had been acknowledged by international auto industry to be a possible practical and economical fuel for automobile in the future.
Like ester type biodiesel fuel, green diesel is a next generation transportation fuel emerging due to the need for a renewable replacement of internal combustion engine fuel, which is also fully compatible with existing automotive powertrain systems.
Different plant alternatives (Simple Cycle Gas Turbine, Gas Micro-Turbine, Gas Internal Combustion Engine, Fuel Cells) in the optimization procedure are taken into account with the aim of determining the optimal typology, size and operative strategy of the trigeneration system.
Recently, C. cellulolyticum was engineered to produce isobutanol, a possible alternative to gasoline to fuel combustion engines, directly from cellulose [ 5].
Engineers have taken a variety of approaches to hypersonic aircraft over the years: the X-51 is called a WaveRider because it literally rides its own shock waves, and is powered by a scramjet, a variation of the traditional ramjet engine, where the exhaust from fuel combustion is compressed as it goes through the engine.
