Meets emissions requirements
- The advanced single-point injection electronic control system of Woodward, oxidized aftertreatment, Euro V Emission
Lightweight design
- The total machine weighs only 500kg - powerful CAE analysis capability to optimize design while maintaining strength and reliability
- Plastic and aluminum alloy materials are USed extensively in flywheel hoUSing, water pump, oil pan, rocker arm cover, air intake pipe, etc
Excellent NVH performance
- The body is a portal-like design, with high body strength and low vibration, which greatly reduces noise
- Rear gear chamber, high precision gear is USed to shear gear, which provides stable operation and further reduces mechanical noise
- Multiple injection technology to reduce combustion noise significantly
Ultra-low fuel consumption
- The lowest gas consumption rate is 188g/(kW•h); low-speed fuel consumption area covers the typical conditions of Buses, which are 1300-1500r/min, for better fuel economy
Powerful
- Raise low speed torque and maximum torque, good responsiveness when accelerating and pulling away, meet the power requirements of the whole vehicle
Adaptable
- Power loss at 2800 meters above sea level, ultra-low power loss at 4500 meters of typical operating conditions
- Starting zero at -20°C in low temperature environment failed
Adaptability
- Small in size and light in weight, this is the ideal driving force for 7.5-8.5 meters of city bus
- The engine can be carried in parallel with 3 generators to meet the power needs of various Buses
- The body's air conditioning carries the structure, and the air conditioning does not come into direct contact with the entire carriage, further improving the NVH performance of the whole vehicle and improving the quality of the whole vehicle
