产品概述
The 4M12 series is a new generation of high-power-density engines independently developed by Weichai, featuring a compact structure and superior fuel economy; Power output ranges from 110 to 148 kWm, suitable for 90–132 kWe generator sets.
产品优势
Fuel System: Electronically controlled high-pressure common rail (HPCR) system delivers high injection pressure for increased engine power and improved fuel atomization, resulting in superior fuel economy; specifically developed electronic control functions for generator set operating conditions meet various control and speed regulation requirements
Air Intake System: High-efficiency turbocharger for optimized air intake and more efficient combustion
Superior NVH Performance: Utilizes pilot injection technology and a high-precision meshing gear train to achieve low engine vibration and noise
