Diesel engine
YC4D series engine is a classic power product developed by Yuchai, with a market share of more than 500,000 units. The engine for generator sets developed on its basis is reliable, durable, and energy-saving.Environmental protection, compact structure, strong transient loading capacity, good maintainability and other advantages.
Model Features
?The main structures of the engine, such as the engine body, cylinder head, crankshaft and connecting rod, have been tested for a long time to ensure the high reliability of the whole machine.
?The cylinder head integrated water outlet manifold design is adopted to reduce the sealing surface and improve the sealing reliability.
