The Best Choice for Industrial Power
Low Expenditure
■ Low fuel consumption, effectively reducing operating costs
By optimizing control strategies and combining with the actual usage conditions of the equipment, further improving fuel economy. The advanced product platform and optimized design make the economic fuel consumption range of the engine wider, more fuel-efficient than engines of the same type. The five key systems of the electronically controlled engine are all developed by Cummins, and have been applied and verified in different fields worldwide, ensuring excellent economy and reliability of the product.
■ Less maintenance costs and time, greatly reducing the downtime losses of construction machinery
■ Longer equipment maintenance cycle up to 400 hours
■ Low failure rate, with average maintenance time and cost about half of engines of the same type, longer working time
■ Engine volume smaller than engines of the same type, larger maintenance space, faster maintenance
■ Strong interchangeability, more convenient for equipment upgrade
High Income
■ High reliability brings high availability, creating more value for you. Electronic control technology effectively solves problems such as engine surging, load drop, and white smoke. At the same time, the use of three-stage fuel filters better protects the engine's fuel system, systematically improving the reliability and durability of the engine. The "multi-functional" integrated design reduces the number of parts by about 25% compared to engines of the same type, with fewer connections and higher engine reliability. The main bearing load-bearing area is about 30% larger than that of engines of the same type, ensuring a long working life of construction machinery under high-load working conditions.
■ Good power performance, higher work efficiency
■ Compared with engines of the same type, the torque reserve coefficient is larger, and the power performance is stronger, meeting various complex working conditions. The turbocharger with exhaust bypass valve effectively improves the engine's power reserve and instantaneous response.
Better environmental adaptability
■ After extensive tests in various harsh environments such as high altitudes, high temperatures, high humidity, and extreme cold, it can easily cope with various extreme working conditions. Strong adaptability to high altitudes, equipment can operate without power reduction at an altitude of 4000m, and can be used continuously at 4500m.
■ Strong low-temperature load start-up ability, improving the low-temperature load start-up performance according to the actual usage characteristics of the equipment.
Lower noise
■ Through the optimization of control strategies and the application of noise reduction options, it has lower noise.
■ The "heart" of Cummins engines makes your machine more valuable.
