6.7L CUMMINS Engine
Based on its forward-looking design and development capabilities, Cummins has developed corresponding solutions for different emission standards. Coupled with strong and mature supporting capabilities, Cummins’ emission control technology can achieve a perfect match with the lifecycle and the entire vehicle, thereby enabling customers to achieve the best economic benefits. Especially in the engine road market, the Cummins 6.7L engine has demonstrated excellent starting ability.
6.7L CUMMINS Engine
The Cummins 6.7L engine is still in a continuous development stage, and currently includes four models: B6.7, QSB6.7, ISB6.7, and ISD6.7. Among them, QSB6.7, ISB6.7, and ISD6.7 engines are widely used in well-known domestic and foreign brand buses.
B6.7
The power range is 155-326Hp, which can meet and exceed the ultra-low emission levels required by Stage 5.
- Automatic start stop function:Through hardware and software upgrades, the B6.7 engine has an automatic start stop function, which can help customers further reduce operating costs and environmental impact by reducing noise and carbon dioxide emissions.
- Absence of EGR:After being combined with the Cummins single module post-treatment system, efficient SCR technology enables the B6.7 engine to be cooled without the need for exhaust gas recirculation (EGR). The absence of EGR means that the engine is lighter in weight, simpler in design, easier to install into equipment, and meets lower cooling requirements. Simpler configuration also means better reliability, thereby reducing total operating costs and improving availability. This product is very suitable for various off-road equipment, including crushers, screening machines, wheel loaders, excavators, forklifts, dock tractors, and empty container loaders. Cummins engineers can customize it mechanically and electronically for each type of machine.
QSB6.7
The power range is 205-263Hp, emission level China Stage- III. It has the advantages of high reliability, strong power output, excellent fuel economy, environmental protection, energy conservation, and easy maintenance and repair, making it suitable for various application scenarios.
- Excellent fuel economy: The QSB6.7 engine adopts advanced combustion technology and combustion control system, which can achieve lower fuel consumption, improve fuel economy, and reduce operating costs.
- Easy to maintain and repair:The design of QSB6.7 engine considers the convenience of maintenance and repair, with each component easy to disassemble and replace, reducing maintenance costs and downtime.
ISB6.7
Power range 185-300hp, emission level is Euro III-V, widely used in large and medium-sized buses, trucks, and municipal vehicles.
- Economical use: The engine subsystem is highly integrated, achieving fuel saving and consumption reduction through multiple channels, higher power output, stable and reliable operation performance under complex working conditions, excellent power performance, ultra long service life, and long maintenance intervals.
- Intelligent Electronic Control: Advanced electronic control integration system, super large capacity electronic control module, collects information from all transmission system components such as electronic gearbox, ABS braking, and ASR anti slip through standard data bus, forming a seamless information flow. Through high-speed data communication interface sharing, it ensures that the engine maintains the best working state during operation, maintains efficient fuel saving and low emissions under different load conditions, and has self-protection and intelligent diagnosis functions such as anti vibration, anti overheating, and anti overload, with excellent reliability and durability.
ISD6.7
The power range is 140-300hp, emission level is Euro III-V, widely used in 6-11 meter road buses, tourist buses, buses, and school buses. ISD has high operational efficiency, long work cycle, and durability.
- 1. Efficient fuel saving:The high-pressure common rail fuel system has a higher injection pressure, up to 1800 bar, more precise control of injection timing and fuel quantity, more complete combustion, a wide range of economic fuel consumption, significantly improved fuel economy, further improved low-speed performance, better noise reduction and cold start performance.
- Powerful electronic control system:The advanced electronic control system has powerful functions and can digitize and intelligently manage systems such as intake, exhaust, cooling, fuel, braking, and post-processing. It has established a powerful information exchange platform between the engine and subsystems, as well as between the engine and the entire vehicle, supporting real-time monitoring and early warning of faults.
