WebSep 17, 2024 · There are two main forces involved in scavenging: The piston pushes out exhaust fumes while travelling back up to top dead center, and. The pressure differential between the combustion chamber and the exhaust manifold causes the exhaust gases to get pulled out. Allow us to explain — the pressure within the combustion chamber is 6 to 7 … WebBoiler air supply casings, exhausts (uptakes) and scavenging air belts of propulsion machinery are to have early-stage warning devices to detect potential fires and give alarms.

The three main types of scavenging for two stroke engines are cross flow, uniflow and loop flow. Notice on the below image that the cross flow and loop flow scavenging designs use ports only, whilst the uniflow design uses valves (for exhaust) and ports (for inlet).

WebSep 15, 2024 · Oxygen in the form of fresh air is taken into the combustion chamber to support the combustion process. This method of taking in fresh air while releasing exhaust gas is known as scavenging. The scavenging process is one of the key factors determining the overall power of the engine; as the poor scavenging process leads to poor combustion.
