Lombardini Diesel Engine – 7.5HP, 4-Stroke, Air-Cooled - 15LD350

High-Performance 7.5HP Diesel Engine

The Lombardini 15LD350 4-Stroke Diesel Engine delivers dependable mechanical performance for heavy-duty agricultural, industrial, and construction equipment. Engineered strictly to handle demanding physical workloads, it generates a maximum output of 7.5 HP (5.5 kW) alongside a high-torque threshold of 16.6 Nm at 2400 RPM. This robust power profile ensures that connected machinery can smoothly overcome sudden mechanical resistance or load spikes without stalling.

To guarantee continuous operation even in elevated job site temperatures, the unit utilizes a highly effective forced air-cooling system that actively protects the internal engine block. It is also equipped with a generous 4.3-liter fuel capacity designed to support extended running times, heavily minimizing operational downtime for refueling. Despite its high power output, the engine is built into a highly practical and compact structural frame weighing just 33 kg, making it exceptionally easy to integrate into portable power solutions and mobile machinery.

Key Features & Benefits:

• Maximum Automotive Power (N - 7.5 HP): Supplies a 5.5 kW burst of reserve power at 3600 RPM for brief periods when machinery encounters severe physical resistance.
• Intermittent Work Power (NB - 7 HP): Rated specifically for tasks with fluctuating workloads and frequent start-stop cycles, maintaining a stable 5.1 kW output.
• Continuous Duty Power (NA - 6.4 HP): Engineered for steady, 24/7 marathon applications, safely outputting 4.7 kW without the risk of overheating or premature wear.
• Direct Injection Efficiency: The 349 cm³ displacement mechanism utilizes direct injection to precisely control fuel delivery and maximize overall combustion efficiency.
• High-Torque Performance: Generates up to 16.6 Nm of torque at lower engine speeds (2400 RPM) to keep machinery moving smoothly through sudden load spikes.
• Optimized Fluid Capacities: Houses a 4.3-liter fuel tank for extended daily runtime alongside a 1.2-liter oil sump that guarantees thorough internal lubrication.
• Versatile Cooling System: Forced air cooling ensures the engine maintains an ideal operating temperature, even in hot climates.
• Compact & Lightweight: Weighing approximately 33 kg, its streamlined design allows for easy integration into mobile machinery and portable equipment.
