An engineer from St. Petersburg, Andrey Efimov, has developed a new cylinder head for powerful liquid-cooled gas piston engines. The development is designed for installations with a capacity of up to 2000 kW, which are used in power plants, industrial facilities, and cogeneration systems.
The main feature of the design is the technological openings in the body, through which the condition of the internal cooling channels can be monitored and flushed without complex engine disassembly.
The new head is made of cast iron and features a developed internal cooling fluid circulation cavity.
Channels run inside around the combustion chamber, valve areas, and exhaust manifold – this is where the highest thermal loads occur.
The development is aimed at heavy gas piston units with a V-shaped configuration.
Such engines can have a total displacement of about 90 liters, cylinder diameters of about 180 mm, and operate at 1500–1800 rpm to generate electricity at 50 or 60 Hz.
