New Generation 2.0T High-Performance, Low-Fuel-Consumption Diesel Engine.
High Power
Achieves lower starting RPM, greater torque output, and an expanded continuous RPM range for smoother acceleration and instantaneous power delivery, elevating your driving experience.
Features a bowl-shaped combustion chamber, high-efficiency spiral tangential intake ports, and a 2000bar high-pressure common rail system. Multiple friction-reduction and loss-mitigation measures ensure more complete combustion and lower fuel consumption.
The High-Pressure Common Rail System
With 2000bar system pressure and high-speed electromagnetic fuel injectors, it significantly improves fuel atomization and ensures more complete combustion.
High-Pressure EGR System
With high-pressure EGR technology, it reduced engine pumping losses and NOx emissions, enhancing overall vehicle fuel economy.
Optimized Intake System
Incorporates spiral tangential intake ports and adds guide shielding structures at the cylinder head intake ports to optimize airflow shape, improve flow field intensity, increase air utilization efficiency, and significantly enhance fuel economy.
60%
Swirl ratio increased
NVH
Delivers NVH performance comparable to gasoline engines, with development focused on creating the quietest diesel engine through both active and passive noise reduction measures.
Camshaft Parallel Configuration with Backlash Elimination Gears
By employing backlash elimination gears and optimally matching the torsional spring stiffness of the secondary gears, gear vibration is reduced by 74% while optimizing camshaft torsional vibration amplitude, resolving two typical NVH issues (gear rattle and whine), reducing engine gear rattle noise by 5dBA.
Optimized Timing System Design
Proper phase alignment between the timing belt and pulleys reduces belt tension and improves meshing noise. Compared to chain systems, the belt system generates lower noise levels. Combined with an upper plastic and lower cast aluminum timing cover, it provides excellent shielding against both high- and low-frequency noise on the timing side.
Integrated Bottom-Mounted Balance Shaft
Enhances overall vehicle NVH comfort with an added balance shaft configuration, positioning the drive gear at the front of the crankshaft to reduce torsional vibration excitation and minimize gear rattle noise, resulting in a measured reduction of over 5dBA in engine bottom radiation noise.
