Core functions

Dynamic fuel control

ECU monitors real-time parameters such as intake flow rate, power generation, and diesel flow rate.

Update fuel ratio 50 times per second and automatically optimize natural gas substitution rate.

Dynamic Setpoint Protection ™ (DSP) dynamic protection

Dynamically set safety thresholds within the full load range.

Compared to the benchmark curve of pure diesel, seamless switching back to pure diesel without interrupting power supply in case of abnormalities.

Seamless mode switching

dual-fuel ↔  Pure diesel automatic/manual switching.

There is no power drop or fluctuation during the switching process.

Monitoring and Diagnosis

The touch screen displays real-time data, historical records, and alarm information.

Support testing mode: Debugging the system under pure diesel fuel.

Security system

gas safety

Double redundant normally closed DC gas shut-off valve+manual shut-off valve.

Combustible gas detection+flame detection.

Automatically cut off gas and switch back to diesel in case of leakage/fire.

Engine protection

Exhaust temperature/turbine temperature protection

Intake boost pressure/temperature protection

Engine overspeed protection

Detonation (vibration) detection

Abnormal diesel/gas flow protection

Key issues

Question 1: How can EVO-SP 2600 achieve dual fuel modification without damaging the engine? What are the core advantages?

answer:

The system adopts completely external components, without modifying the engine body structure such as cylinders, pistons, injectors, cylinder heads, etc., and fully retains the original diesel system.

Core advantages:

Non destructive modification does not affect engine warranty and lifespan.

It can be switched back to 100% diesel operation at any time, with unchanged emergency reliability.

Installation only takes 6-8 hours, with short downtime.

Question 2: DSP (Dynamic Setpoint Protection) ™） What is dynamic protection? What is better than ordinary protection?

answer:

DSP is a dynamic safety threshold technology for full load intervals, rather than just setting a protection point at full load.

Advantage:

Follow the engine load adjustment protection parameters throughout the process.

Based on the pure diesel operating curve, anomaly identification is more accurate.

When triggered, seamlessly switch back to diesel, ensuring uninterrupted power generation and no load shedding.

Question 3: What are the gas safety designs of EVO-SP 2600? What level of certification has been achieved?

answer:

Safety design:

Double redundant normally closed gas solenoid valve+manual shut-off valve.

Combustible gas detector+flame detector.

Alarm automatic gas cut-off+diesel cut-off, supports remote linkage.

Certification

Through the strictest global safety standards such as UL, CSA, CE, FM, AGA, GOST, etc., it can be deployed globally.
