Introducing the RD 186F, a high-performance diesel engine from DEHRAY’s industrial power series—engineered as a core power unit for generators, water pumps, construction machinery, and agricultural equipment. Adhering to DEHRAY’s “DURABLE POWER FOR HEAVY DEMANDS" philosophy, this single-cylinder engine delivers a rated power of 4.0kW at 1500r/min, combining robust output with exceptional fuel efficiency to meet the continuous operation needs of industrial and commercial applications.
The RD 186F stands out with its heavy-duty structural design—featuring a cast-iron cylinder block and crankcase that enhance heat resistance and load-bearing capacity, significantly extending service life even in harsh working environments. As a 4-stroke air-cooled engine, it eliminates the need for complex water cooling systems, reducing maintenance costs and improving adaptability to dry or remote areas. It holds international certifications including CE, ISO9001, and EPA, ensuring compliance with global emission and quality standards for widespread application.
What sets the RD 186F apart is its optimized combustion system—equipped with a high-compression ratio (19.0∶1) and efficient fuel injection technology, it achieves a lowest fuel consumption of 220g/kW.h, reducing operational costs. The engine’s T.C.I ignition system ensures reliable startup in low-temperature environments, while the large-capacity oil sump (1.6L) and forced lubrication system protect key components from wear. With its compact dimensions and flexible mounting design, the RD 186F is easy to integrate into various equipment, making it a trusted power core for industrial and agricultural machinery.
