6BTAA5.9-C190 I. Core parameters and performance Power output Rated power: 142kW (2200rpm), maximum torque 800N·m (1500rpm), power output stability is better than similar four-cylinder models. Using supercharged intercooling technology, the combustion efficiency is 18% higher than that of traditional diesel engines, and the fuel consumption rate is reduced to 215g/kWh. Emission control meets the National II emission standards, and the nitrogen oxide (NOx) emissions are reduced by 12% compared with the previous generation of models, which is compatible with the environmental protection regulations of non-road machinery in many European countries. II. Application fields and adaptation scenarios Construction machinery Widely used in excavators, bulldozers and concrete pump trucks, and adapted to domestic construction machinery brands such as XCMG and Shantui. Road transportation Can match Dongfeng EQ series heavy-duty trucks to meet the high-load transportation needs of mountain roads. Generator set As a backup power unit, it supports the stable operation of generator sets below 800kVA. 3. Technical advantages and design innovation ‌Modular maintenance‌ Provide modular maintenance solutions for long cylinder block assembly and medium cylinder block, and the time required to replace core components is 40% shorter than that of traditional models. Adopt electronically controlled high-pressure common rail injection system to achieve rapid start at -25℃ low temperature. ‌Structural optimization‌ The cylinder block adopts platform reticulated honing process, and the oil consumption is reduced to 0.1L/h, extending the overhaul cycle to 12,000 hours.
