31. The inlet valve is wide open. 32. The inlet valves are pulled open with an eccentric-driven trips, the rapid closure is damped using a dashpot. 33.

As before the engine is arranged to have interchangeable exhaust and inlet valves on opposing sides of the engine. 38. At the end of each line is an inlet valve with a spring-loaded closure gate and a power switch. 39. The opening inlet valve can then at typical compression ratios fill 10 % of the cylinder before beginning downward travel. 40. Power of the carbureted version also increased slightly at the same time, owing to the employment of larger inlet valves .
