Technical features of QSB5.9 series engines QSB5.9-C130 QSB5.9-C150 QSB5.9-C160 QSB5.9-C170 QSB5.9-C180 QSB5.9-C190 QSB5.9-C210 I. Technical features Combustion technology High-pressure common rail and direct injection technology are used to optimize combustion efficiency and reduce emissions. No aftertreatment system is required to meet the non-road stage III emission standards. Platform and control Based on the QS platform design, it supports diversified control strategies to adapt to different working conditions. The integrated cylinder block and cylinder head design reduces the number of parts by about 40%, significantly reducing the failure rate. Process optimization The cylinder bore adopts platform reticulated honing technology, combined with new piston ring and sealing gasket technology to reduce oil leakage and loss. III. Application areas Engineering machinery: such as excavators, loaders, etc., adapt to complex working conditions. Automotive power: trucks, buses, etc., support the potential for emission upgrades from National III to National VI. Generator: meet continuous output power requirements.
