FEV’s 698 cm 3 Extremely Downsized Engine. will show its Extremely Downsized Engine (EDE) at next week’s 2010 SAE World Congress in Detroit. Direct injection (DI) is integrated by replacing the twin spark ignition with a single spark plug on the exhaust side with the DI device in place of the removed spark plug on the intake side.

Simulation study finds Miller version of Scuderi engine can deliver twice the BMEP as naturally aspirated version, theoretically enabling 50% downsizing while maintaining performance. Applying the Miller cycle to the Scuderi engine (right) entails downsizing of the compression cylinder. Source: Scuderi. Click to enlarge.

Cummins made extensive use of aluminium as well as space-saving design features for new engine weight control. Exhaust system configuration. The approach that Cummins and partners have taken features: Replacing the aluminium V8 gasoline engine and emission control system with smaller diesel (2.8-liter)

The basic Scuderi engine divides the four strokes of a combustion cycle among two paired cylinders—the left cylinder functions as an air compressor, handling intake and compression, while the right cylinder handles combustion and exhaust. Key to Scuderi’s split-cycle design is that it fires after top dead center. Earlier post.).

One significant trend is engine downsizing coupled with turbocharging. Smaller, turbocharged engines can be used to raise fuel economy while meeting or exceeding the power and torque of larger engines, allowing engine downsizing and improved fuel economy with little or no performance compromise.
