2. Working Principle and Power Switching Mechanism of Dual-Fuel Forklifts

2.1 Definition and composition of dual-fuel power system

Main components: engine, LPG gas supply assembly, gasoline fuel supply system, switching control unit, sensors

2.2 Two operation modes

LPG mode: clean combustion, low noise, suitable for indoor warehouse operation

Gasoline mode: stable power output, convenient refueling, suitable for outdoor and long-time continuous work

2.3 Flexible power switching logic

Manual switching operation process

Safety interlock design: protection logic during switching, avoid flameout and abnormal combustion

Reminder function of fuel/gas residual quantity

2.4 Comparison of combustion characteristics under two fuels

3. Performance Test and Driving Verification of Dual-Fuel Forklifts under Factory Working Conditions

Combined with the forklift driving test content you previously concerned

3.1 Test conditions and test standard basis

Test site: closed factory area, including flat channel, ramp, curve, loading and unloading area

Reference standard for off-road industrial vehicles / factory special vehicles

Test items: starting, straight running, turning, ramp driving, load-carrying operation, switching test under working state

3.2 Test results of power and driving performance

Power consistency: comparison of traction, lifting speed in LPG and gasoline mode

Safety performance: braking stability, anti-roll performance during turning and ramp driving

Adaptability: performance switching without stopping in the event of LPG exhaustion

3.3 Emission and noise test data

Exhaust emission comparison with pure gasoline forklifts

Noise test result for indoor warehouse environment

3.4 Reliability summary of continuous cycle test

4. Application Advantages and Scenario Analysis in Factory Material Handling
