A.
The cost of the engine, for the same power and economy, is more than that of a simple steam engine |
|
B.
The forces in the working parts are increased as the forces are distributed over more parts |
|
C.
The ratio of expansion is reduced, thus reducing the length of stroke |
|
D.
The temperature range per cylinder is increased, with corresponding increase in condensation |
