Other Parts
This engine adopts 147mm bore ×154mm stroke, compression ratio 16.4:1, 4-valve per cylinder with overhead camshaft layout, equipped with high-pressure common rail direct injection fuel system and air-to-air turbo aftercooling structure plus cooled EGR exhaust recirculation system. Rated working speed fixed at 1800rpm, overall dimension 1462×1017×1422mm, net dry weight 1150kg.
Liquid cooling configuration with vertical outlet thermostat and centrifugal water pump, standard engine oil filling volume 57L and coolant capacity 55L, 24V electric starting system and SAE standard flywheel mounting interface. COMⅢ version is optimized on ECU program for heavy-load constant operation, specially matched for large heavy-duty host equipment.
Meet multi-region Stage Ⅲ emission via cooled EGR design without extra aftertreatment to simplify pipeline layout and reduce later maintenance cost.
Large displacement turbo aftercooled design brings outstanding low-speed torque to sustain long-period continuous heavy-load working conditions.
COMⅢ exclusive ECU calibration optimizes fuel injection logic for lower comprehensive fuel consumption under variable heavy loads.
High-pressure common rail injection plus 4-valve structure improves combustion efficiency and enhances overall operational economy.
Cast iron cylinder block and mature internal structure reduce breakdown rate and extend core component service lifespan.
Standardized installation dimension and wiring plug support convenient direct replacement during equipment overhaul.
