Starting air system for Marine diesel engine
Diesel engines are started by supplying compressed air into the cylinders in the appropriate sequence for the required direction. A supply of compressed air is stored in air reservoirs or 'bottles' ready for immediate use. Up to 12 starts are possible with the stored quantity of compressed air.
STARTING AIR SYSTEM - Knowledge Of Sea
Jun 20, 2023 · The main air receivers are used to supply the starting air for the main engine and for the three diesel generator engines with the air being supplied to the three generator engines using a separate pipeline from that used for supplying the main engine.
This device is usually driven by the engine camshaft and supplies pilot air to the control cylinders of the cylinder air start valves. The pilot air is then supplied in the appropriate sequence for the direction of operation required.

Main Engine Start Air System - MarineSite.Info
MAIN ENGINE AIR STARTING SYSTEM. The receiver stop valve is opened and air passes to the automatic valve and to the master valve, assuming turning gear is disengaged. Both valves remain closed at this stage. When the start lever is moved to the start position the master valve opens allowing control air to the distributor slide valve loading ...
Air-start system - Wikipedia
An air-start system is a power source used to provide the initial rotation to start large diesel engines and gas turbines. Diesel engines. Direct starting. Compared to a gasoline (petrol) engine, a diesel engine has a very high compression ratio, an essential design feature, as it is the heat of compression that ignites the fuel.
