Product advantages
More reliable-high configuration, low failure rate
- Global procurement, select domestic and foreign famous suppliers for parts and components, effectively improve reliability and reduce failure rate.
- The 93 sand dust filter adapts to various environments such as dusty and different soil quality, extending the maintenance period of the main filter element and reducing user operating costs.
- The crankshaft is made of forged steel, which has higher strength, and the front end output can reach.
- Integrated fuel filter is injected to facilitate vehicle layout and maintenance.
- Choose suppliers of parts and electrical systems to effectively reduce electrical system failures.
More efficient-strong power and high efficiency
- High speed and constant power, low speed and large torque, good acceleration.
- The torque reserve rate is up to 25% or more, which is more suitable for different working conditions, and the work efficiency is high.
More economical-accurate fuel control, low fuel consumption
- Optimize supercharger, fuel injector and calibration ECU data, through flexible control of fuel injection pressure, realize multiple injections, reduce engine fuel consumption and improve work efficiency.
More comfortable-low vibration and noise
- Large-flow water pump and low-speed fan effectively reduce cab noise and driving fatigue.
- Controlled by the electronic control system, the fuel injection pressure is more stable, the response is fast, the fluctuation is small, and the combustion noise is low.
Smarter-real-time monitoring, remote control
- Installment management, which can locate and remind payment at any time for the whole machine that implements installment payment.
- Fuel consumption management, real-time recording, monitoring, and storage of engine real-time fuel consumption and comprehensive fuel consumption.
- Vehicle speed management, real-time recording, monitoring and storage of real-time vehicle speed.
- Positioning management, can locate the position of the whole machine, and accurately grasp the position information of the whole machine.
- Security and anti-theft, can track and locate the stolen machine, and lock the machine remotely.
- Abnormal reminder, real-time monitoring of engine operating parameters and early warning of hidden troubles.
- Remote diagnosis, automatic fault alarm, remote engine fault analysis and judgment.
More adaptable-complex environment, flexible response
- Adapt to high temperature and dusty environment.
- Good cold start, smooth start without any auxiliary measures at -10℃.
Drain interval
Environmental adaptability
