SC11C (121) series diesel engines are American Caterpillar (Caterpillar) 3300 series license products, tailor-made for construction machinery, carefully built, the global possession of more than 1 million units, Caterpillar provides continuous technical support. At the same time, Shangchai Company also introduced Caterpillar's main processing equipment and product test equipment. By adopting American advanced technology, it paid special attention to the reliability of parts and components in design and manufacturing, making the 121 diesel engine famous for its high quality and high reliability. Become the recognized trump power of construction machinery.
Technical specifications of diesel generator set:
1. High reliability
The sophisticated design of the parts and the whole machine implements the design concept of high reliability and long life, the main parts and the whole machine have the same life, and the important friction pairs are very reliable and durable. The actual supporting application statistics show that the average time between failures of loaders and bulldozers is more than 4,000 hours, and the overhaul period is more than 10,000 hours. The average time between failures of the D7G (160kW/2000r/min) crawler bulldozer with harsh environment is 4167h, and the average overhaul period is 11500h.
2. Strong power
The displacement is 10.45 liters, which is larger than the power displacement of competitors' construction machinery; the torque reserve coefficient can reach up to 1.5, with extraordinary power and good responsiveness, and easy operation.
3. Very high work efficiency
It is 23% higher than the same period last year; the fuel consumption rate per unit of operation is lower than 10% (how fast is better).
4. Strong adaptability to plateau
On a plateau at an altitude of 4500 meters, the power of the diesel engine is not lost.
5. Easy maintenance and simple repair
6. Sufficient spare parts reserve
All parts are made in China, the price of repair parts is reasonable, and the parts are distributed nationwide, making it easy to purchase.
Seven, excellent low temperature start performance
