Differences Between Domestic and Imported Generator Sets
Many users today find themselves torn between choosing domestic or imported generator sets during the purchasing process. Below we outline key distinctions between domestic and imported units, along with their respective applications and features.
Domestic Generator Sets
Shangchai Generator Sets: Powered by Shanghai Diesel Engine Co., Ltd.'s “Dongfeng” diesel engines. These engines deliver excellent power performance, substantial torque reserves, and low fuel and oil consumption rates. Equipped with J98 or J114b exhaust gas turbochargers, they exhibit strong high-altitude capability, maintaining less than 3% power reduction when operating at 5,000m elevation.
Weichai Generator Sets: Powered by Ricardo R-series engines—a joint venture between Weifang Diesel Engine Factory and a British company—models R4105 and R6105 cover a 40KW-100KW power range. Weifang diesel generator sets offer stable quality and excellent value. Manufactured with advanced technology, Weifang diesel generator sets excel in power performance, fuel efficiency, and reliability among comparable diesel products, making them a top choice in the mid-range power segment for domestically produced units. Yuchai Generator Sets: All Yuchai generator sets are powered by Yuchai's own diesel engines, delivering robust performance. They output rated power at altitudes below 1000m and sustain 110% overload capacity for under one hour. Fuel and lubricant consumption rates significantly outperform domestic competitors. These units feature low vibration, minimal noise, high reliability, and low emissions, meeting environmental standards.
Jichai Generator Sets: Engine design technology developed independently and through collaboration with AVL, an Austrian global internal combustion engine designer. Features high voltage regulation precision, excellent dynamic performance, minimal voltage waveform distortion, high efficiency, and a compact structure. Wudong Generator Sets: Available in vertical 4-cylinder, vertical 6-cylinder, and V-type 12-cylinder configurations, with power ranges from 100KW to 630KW. Meeting diverse user requirements, they deliver superior power performance, economy, and reliability through closed-loop cooling systems. Simple operation, easy maintenance, and robust service networks are provided.
Imported Generator Sets
Cummins Diesel Generator Sets: Utilizing genuine Cummins power equipment paired with branded alternators, these units offer energy efficiency, durability, safety, and convenient maintenance. They represent the premier choice for backup power in enterprises and institutions.
Perkins Diesel Generator Sets: Within the power generation sector, Perkins diesel generator sets ranging from 7KW to 1811KW deliver outstanding performance, reliability, and durability. In 1998, Perkins was acquired by Chrysler Corporation and became part of the Caterpillar Group. Although Perkins entered the Chinese generator market relatively late, it was rapidly accepted by customers and quickly captured a significant market share, achieving remarkable success in the generator set sector. German Deutz Diesel Generator Sets: Featuring compact construction, rational design, reliable and outstanding performance, extended operational lifespan, and economical operation. Product offerings include three major platforms—C, E, and D—covering power ranges from 10 to 1760 kW. With over 300 variants and adaptable models, they deliver technologically advanced, specialized power solutions for diverse applications including medium-to-heavy trucks, light vehicles, buses, and construction machinery. The products boast a series of significant advantages including advanced technology, reliability, energy efficiency, and environmental friendliness. Equipped with an intake recirculation function, they perform exceptionally well in plateau and high-altitude regions. Mercedes-Benz Diesel Generator Sets: Utilizing the advanced ADEC electronic management system and state-of-the-art common rail injection technology, precise electronic control ensures accurate fuel injection, complete combustion, lower fuel consumption, and enhanced energy efficiency and environmental performance. The first overhaul interval can exceed 30,000 hours.
