    Definition turbocharger, designed to allow the effective aspect ratio (A:R) of the turbo to be altered as conditions change Reference "COM-EN, based on:Wikipedia > Variable-geometry turbocharger. http://en.wikipedia.org/wiki/Variable-geometry_turbocharger [4.4.2013]"
    Comment This is done because optimum aspect ratio at low engine speeds is very different from that at high engine speeds. If the aspect ratio is too large, the turbo will fail to create boost at low speeds; if the aspect ratio is too small, the turbo will choke the engine at high speeds, leading to high exhaust manifold pressures, high pumping losses, and ultimately lower power output. By altering the geometry of the turbine housing as the engine accelerates, the turbo's aspect ratio can be maintained at its optimum.
