Authors Abstract
Content
A turbocharger which has four pairs of fixed vanes and movable vanes inside the turbine scroll was developed. A 1.2-liter experimental gasoline engine with this turbocharger was made and mounted in the body of a passenger car. This variable-geometry mechanism did not need a waste-gate system. Results of bench tests showed that this engine generated a 93.3 kPa (700 mmHg) boost pressure over a 6,000 rpm range. This paper presents the mechanism, operation, and performance data of this variable-geometry turbocharger, as well as the performance data of the 1.2-liter experimental engine and this passenger car.
