<p>The cylinder head (401) of a turbocompounded 2-stroke piston engine incorporates, for each cylinder (400), an indirect combustion chamber (402), which is connected to the cylinder clearance volume (413) by a passage (412). The indirect combustion chamber (402) incorporates the inlet valve (408) so that when the valve opens, turbocharging air flows into the cylinder through the chamber (402) and the passage (412). This allows a large proportion of the cylinder head area to be devoted to the exhaust valves (410), with advantages in good scavenging and maximising mass flow rates through the cylinder.</p> |
