Technical features

Fuel saving:

Using electronically controlled high-voltage common rail system, the injection pressure is higher, the atomization rate is greater, and the combustion is more fully;

Independent research and development of combustion chamber design, intake and exhaust duo, cylinder head three-hole position and other technologies, diesel engine intake and exhaust system, combustion system in the leading domestic level;

Optional self-developed integrated VCU unit (polymorphic switch, etc.) to adjust the fuel supply according to vehicle load.

economic:

No need for post-process injection systems and low usage and maintenance costs.

reliable:

Key components such as cylinder block, cylinder head, crankshaft and connecting rod are calculated, analyzed, optimized, reliable and durable by CAD/CAE.

Use the differential pressure sensor to monitor the operation of the post-processing processor in real time.

comfortable:

Using the Dutch LMS vibration test system, the whole machine is optimized for vibration testing, providing NVH support optimization for complete sets, with low vibration and low noise.

Optional cruise function to reduce driving intensity;

Accurate dynamic calibration, so that the vehicle shift smooth;

Optional fuel level switch that automatically alerts emissions through the primary filter.

safe:

Optional exhaust brake, heavy downhill safer;

You can choose to install OBD fault detection for real-time failure alerts.

Full set of optimizations:

Using austrian AVL automotive power transmission system simulation software to calculate, analyze and compare, test and evaluate vehicle matching, the vehicle match is strong and economical.

No need to use the post-process injection system, the vehicle layout is convenient.

Personal design:

Optional air conditioning, power steering, oil or air braking;

Optional GPS system with vehicle management, real-time control, vehicle safety, remote diagnosis and other functions;

Optional remote throttle, speed limit, secondary shutdown, CAN meter and other functions.

The scope of application

5.4 to 6.6 meters of road, tourism, urban passenger buses;

Light trucks;
