West Springfield, Massachusetts – A new engine under development has reached fuel economy of 3.7 L/100 km in a computer simulation study. The Scuderi Engine was modelled against the European class of high-economy vehicles in the simulation.
The Scuderi is a split-cycle engine that divides the four strokes of a combustion cycle between two cylinders, one handling intake and compression while the other handles combustion and exhaust, and requires one crankshaft revolution to complete a single combustion cycle. It is projected to have higher torque, thermodynamic efficiency and lower emissions than possible with current engines.
The engine achieves its best fuel economy when turbocharged. The design is also optimized for air hybridization, when a small air tank is applied to capture and reuse wasted energy.
“Our research results confirm that a typical European small car equipped with the Scuderi engine could realistically achieve significantly lower consumption of just 3.7 L/100 km with substantially lower emissions of 85 g/km,” said Lutz Deyerling, Scuderi Group’s vice-president of European operations and corporate strategy. “This would help car companies to achieve the 2020 fuel standards already in the near future.”
The average consumption of a typical comparable vehicle is 4.5 L/100 km with average CO2 emissions of 104 g/km, the company said. The computer comparison was based on a consumption and emissions analysis of ten typical four-seat small cars, ranging from the Audi A1 to the Fiat 500, all fitted with the most economical Otto engine variant. The technical data was generated by the Southwest Research Institute in San Antonio, Texas.
