Dongfanghong LR4M (Four-Valve) Series Diesel Engine

Product Advantages & Features

Engine Block Structure: Integral water jacket and four-valve cylinder head design meet the requirement of 180bar high explosion pressure; dry cylinder liner equipped with guide plates improves the heat dissipation capacity of the engine cooler and enhances the heat dissipation uniformity among cylinders.

Low-Pressure Fuel System: 500-hour long-life engine fuel filter extends maintenance intervals and reduces maintenance costs.

Electronic Control System: Equipped with BOSCH ECU system, featuring high reliability and strong adaptability.

Fuel System: Adopts BOSCH high-pressure common rail system, delivering high injection pressure, excellent atomization, and superior economic efficiency.

Lubrication & Cooling System: Increased oil pump flow rate guarantees the lubrication of bearing shells and the cooling of pistons; built-in engine cooling structure ensures high heat dissipation efficiency.

Economic Efficiency: Four-speed multi-mode switch function selects the optimal power output curve according to different operating conditions, thereby reducing the overall fuel consumption.

Comfort: Two-axis balance structure reduces overall engine vibration and noise, enhancing operating comfort.

Multiple Power Output Interfaces: Meets various power output requirements and facilitates the layout of the main engine structure; features rear power take-off (PTO) with dual output ports.

Advanced Engine Power Management (AEPM): According to operating conditions, when the power exceeds the standard load, the diesel engine can temporarily increase its power to improve operating efficiency.

After-Treatment System: Adopts dual technical routes of DOC+DPF+SCR and EGR+DOC+DPF, offering U-type or in-line after-treatment devices for enhanced adaptability to overall engine layout.
