Diagramof uniflow scavenging. Scavenging is the process of replacing the exhaust gas in a cylinder of an internal combustion engine with the fresh air/fuel mixture (or fresh air, in the case of direct-injection engines) for the next cycle. If scavenging is incomplete, the remaining exhaust gases can cause improper combustion for the next cycle, leading to

Thetwo basic types of marine diesel engines are – 4 stroke engine; 2 stroke engine; A 4 stroke engine can be installed on the ship to produce electrical power and also to propel the ship (usually in small size vessel). This engine takes 4 cycles to complete the transfer of power from the combustion chamber to the crankshaft.
Engine indicator is the device used to take the indicator diagram, which can be considered as a ‘stethoscope’ for diesel engines. § Indicator diagrams give efficiency of combustion in the cylinder, condition of the running gear, irregularities in fuel pumping and injection and a lot of things.
Remedies Blocked vent screw on the fuel tank. Clean the vent hole. Choked or bent fuel pipe from the tank to fuel pump or fuel pump to carburetor. Clean the pipe remove the sharp bend or replace the squeezed pipe. loose petrol pipe connection. Tighten the unions. Choked petrol strainer in fuel pump or tank. Clean the strainer.
