Abstract
The improved split cycle engine comprises a compression unit 1 mechanically connected to an expansion unit 3 via shaft 2 and to a load via a coupling or centrifugal clutch 5, and a second compression unit 7 which is mechanically connected by shaft 9 to a second expansion unit 8. Compression unit 1 is fed by compression unit 7 and its output is fed to expansion unit 3 via a variable cut-off valve. Fuel is burnt in the air supplied by compression unit 1. The exhaust of expansion unit 3 feeds expansion unit 8. At high cut-off ratios shaft 9 rotates many times faster than shaft 2 and its relative speed is reduced as the cut-off ratio is decreased. At high cut-off ratios the torque output is substantially higher than that of a conventional internal combustion engine so that a complicated transmission is not necessary.
