READ MOREProduct Features
Four valves per cylinder; the fuel system can be optionally equipped with either an electronically governed mechanical pump or an electronic unit pump, effectively improving combustion and emissions while ensuring smooth operation and good fuel economy.
A gantry-type engine block with evenly distributed reinforcements provides high rigidity, compact structure, low vibration, and low noise.
Split camshaft design ensures precise control of valve timing and fuel injection; optimized cam profile reduces impact forces, enhancing reliability and durability.
Equipped with an electric pre-lubrication pump to automatically supply oil before startup.
