Engine fuel saving principle

◆Starting: The engine does not work, only the motor uses its low-speed and high-torque characteristics to start the vehicle alone.

◆Uphill: The generator and battery driven by the engine simultaneously supply power to the traction motor to drive the vehicle.

◆Downhill: The engine is turned off and does not work, and the energy of the vehicle downhill drives the motor to generate electricity and charge the battery. The motor also plays a role in slowing down the vehicle.

◆Constant speed: The engine works in the economic fuel consumption area. When the output power of the engine is greater than the power required by the vehicle, the excess power drives the generator to charge the battery.

◆Acceleration: The motor drives the vehicle at maximum power, and the engine provides part of the power to assist the vehicle in acceleration.

◆Decelerate: When the engine is turned off and does not work, the braking force drives the motor to generate electricity and charge the battery.

Intelligent control, safe and reliable

◆Energy management: engine start and stop, battery charging and discharging, traction motor traction and energy recovery are automatically controlled according to the vehicle status.

◆Driving management: Driving and braking are issued through electronic pedals, and the driving system and braking system respond accordingly.

◆Diagnosis management: The working status of the power system continuously transmits data to the background through wireless transmission, which can realize remote diagnosis and control.

◆Safety management: When the environment and other conditions do not meet the working requirements of the main components of the vehicle, an alarm will be given or the vehicle will be directly ordered to stop working.

No cost to purchase

◆According to our comparative test results, the fuel consumption of the DF45E new energy mining truck is only about 30% of that of the traditional fuel truck when working at full load under heavy load downhill conditions and completing the same transportation volume.

◆The fuel money saved in three years can be used to purchase a DF45E new energy mining truck.

◆Provide financial leasing support, and the financing cost is equivalent to the saved oil cost. There is no high investment burden for using high-end vehicles.

Centralized Lubrication System

◆The so-called centralized lubrication system refers to a system that accurately supplies the required amount of lubricating grease to multiple lubrication points from one lubricating grease supply source.

Wireless tire pressure monitoring system

◆The wireless tire pressure monitoring system is currently the only device that can effectively monitor tire pressure and temperature at any time. It can monitor the changes in tire temperature and pressure at any time. If any abnormal situation occurs, it will issue an abnormal warning via the receiving host to ensure that the tires are always Run under reasonable pressure and temperature conditions to reduce fuel consumption and increase tire life.

◆When the tire pressure is insufficient, it is easy to increase the wear of the tire, thereby reducing the life span and increasing the chance of a tire blowout. If the tire pressure is too high, it will reduce the tire grip. Every 3PSI decrease in tire pressure will increase fuel consumption by more than 1%. It is generally believed that the tire pressure increases by 25% and the tire life is reduced by 15-20%, and the tire pressure is reduced by 25% and the tire life is reduced by 30%. The higher the temperature of the vehicle tire, the lower the strength of the tire, the greater the deformation, the tire wear will increase, and the service life will also decrease.

Self-checking air filter

◆Using the Fleetguard air filter, a joint venture between Dongfeng Company and Fleetguard Company of the United States, and the original imported Tebo pre-filter, the perfect combination of the two can make the engine intake air cleanliness up to 99.9%. Reminding the car owner to maintain the air filter at a time can reduce unnecessary maintenance, improve efficiency and increase the service life of the filter element.
