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

• 500h oil drain interval.

Environmental adaptability

• Temperature -35℃～50℃ ,altitude below 4000m.
