EXPERIMENTAL STUDY OF COMBUSTION FLUCTUATION REDUCTION USING IN-CYLINDER PRESSURE ESTIMATION IN GASOLINE ENGINE

Gasoline engines needs to reduce its negative emission waste and raise its thermal efficiency.Previous studies have shown an improvement of engines by regulating the ignition timing and retaining the engine at certain air-to-fuel ratio.Additional development of the thermal efficiency is anticipated by reducing the oscillation of pressure due to com

Ahmadu Bello University Teaching Hospital at Shika, 547 beds and water demand 154 m3/d, suffers from inadequate and irregular water supply.But there is a nearby abandoned impounding reservoir constructed around 1966, with original storage capacity 636,300 m3.The authors propose to use this reservoir as the main source of water for Shika Hospital.Ho
