Abstract

A four cylinder internal combustion engine has two separate output shafts instead of the conventional crankshaft. These two shafts are mounted co-axially end to end and each carries a free wheel at their inner ends. These free wheels are driven by pinions and a toothed rack which connects each pair of opposed pistons. As the pairs of pistons oscillate one output shaft is driven whilst the free-wheel slips on the other shaft. This type of engine has lower friction losses than those with a connecting rod and crankshaft.
