Engineers from the St. Petersburg company "Rodvig" have proposed a new cylinder head design for gas piston units. It solves the problem of overheating and hidden clogging of cooling channels – one of the main reasons for reducing the service life of units.
Gas piston engines with a capacity of up to 2000 kW operate at the limit of thermal loads. During long-term operation, deposits accumulate inside the head, the circulation of coolant deteriorates, the temperature rises, and the wear of components accelerates.
The key solution is access to cooling channels without disassembling the engine. Technological holes with threaded plugs are provided in the side walls of the head. Through them, cleaning, diagnostics, and monitoring of the internal cavities can be carried out.
In fact, the engineers eliminated the "blind spot" of the design, where it was previously impossible to check the condition of the channels without complete disassembly.
Additionally, temperature sensors can be installed in the fluid circulation zones. This provides precise control of thermal conditions and allows for early detection of overheating.
