- W137405159 abstract "Turbo machinery pressure charging has served to achieve useful power density over many generations of piston engines. This has been mainly due to their virtually frictionless operation and ability to achieve efficient compression and expansion, albeit within a limited range of speeds, which have no direct relationship to the speed of the engine crankshaft. Integrating a piston diesel displacement engine, with steady state turbo devices, inevitably results in mis-matches and compromises, which limit operational effectiveness. The high cylinder volume ratio required for cold starting results in over-compression of the boosted charge and excessive NOx formation. Less than 40 percent of the pressure energy available is recovered at best, leaving most of the energy source to dissipate in the exhaust system. Internal friction has, until now, rendered alternative displacement devices ineffective to recover more of this wasted resource. The novel rotary displacement devices with low friction operation and variable geometry, which are introduced here, enable full advantage to be taken to largely eliminate these losses. Maximum boost can be applied at cranking speed to provide the cold engine with adequate compression for effective starting, and can be optimally reduced thereafter. The displacement action matches that of the piston engine at all speeds, by direct coupling to the crankshaft, which also returns the surplus of recovered pressure energy to the engine output shaft. Dynamometer test results of this new technology applied to a 1.9L and a 1.2L turbo-diesel are described. Gains of 20% in fuel economy and lower NOx emissions are indicated for the 1.9L engine, at the same boost level and power output as for the standard engine. Increased boost with the 1.2L engine can yield power output equal to that of the standard 1.9L engine, 40% improvement in fuel economy and peak cylinder pressures reduced below those of its standard build." @default.
