The Dorman Company in Stafford built an eight-cylinder V-engine with the V at 90°.

"Dorman"

-It gave 80 hp at 1,300 rpm. Only the cylinders were cooled, and the upper parts of the cylinder heads were not.

-The exhausts were free to the outside without channeling.

-At the end of the piston work stroke it uncovered some ports that helped to empty the cylinder in the exhaust phase.

-These holes were known as auxiliary exhaust ports.

From Appendix 6: In the main text the Dorman engine is only mentioned without any image.

-Now we have received the picture we show below, thus completing this chapter successfully.

From Appendix 9: At the Kew museum there are two Dorman engines, a four-cylinder in line and the V8 that is mentioned in the main text.
