“C-450”

-In the beginning, this company was established to develop two-stroke radial engines. Towards 1928 they made the 8-cylinder C-450.

-Actually they were two rows of 4 cylinders each, offset as we can see in the first picture above. The engine gave 150 hp.

“C-450 front view”

-The cleanness of lines is amazing. It works with the two-stroke cycle and what look like cylinder head valves, are actually two spark plugs.

From Appendix 6: Built by the Hurricane Motor Co.

“Hurricane engine on test bench”

-It was known at the time as "Valveless" but the truth is that it was an engine with a two-stroke cycle, so it did not have valves.

-With only 21 moving parts, this radial engine gave 200 hp at 2,000 rpm.

-According to its manufacturer, the engine can operate efficiently and confidently in horizontal, perpendicular and any intermediate angle.

-It has eight cylinders in double row.

-The constructor also tells that four cylinders can be annulled - one row - in case of convenience during operation.
