| 15th July 1910. Re Renault Engine rotary engine C.J. 15/7/10 R1/D15710 I do not think this engine is of any use because the explosive pressure would make an excessive amount of friction on the conical position where the ports are, and the unequal expansion would prevent the ports being gas tight.
