New Efficient Supercharger with Variable Drive for Downsized Gasoline Engines

Green Car Congress

The need to reduce CO 2 emissions is leading to downsized engines, heavily boosted by turbo- or supercharging. Gasoline engines are typically less expensive than diesels for the same application but have higher exhaust temperatures, making advanced turbocharging more difficult. Independent analysis has estimated that the world market for pressure-charged gasoline engines will grow from 2.5
