Lombardini Diesel Engine – 11HP, 4-Stroke, Air-Cooled - 15LD440

Industrial 11HP Diesel Engine

The Lombardini 15LD440 4-Stroke Diesel Engine provides robust, sustained mechanical power for heavy-duty industrial, agricultural, and construction machinery. Designed around a large 442 cm³ displacement, this single-cylinder unit delivers a formidable peak output of 11 HP (8.1 kW). It is specifically calibrated to produce a massive 25.0 Nm of maximum torque at 2200 RPM, ensuring exceptional pulling and pushing force when equipment encounters tough soil conditions or heavy physical resistance.

To support prolonged, high-intensity work cycles, the engine utilizes a precision direct injection system alongside an active forced-air cooling mechanism to systematically prevent overheating in demanding outdoor environments. It is equipped with a 4.3-liter fuel capacity and a substantial 1.5-liter oil sump, which work together to maximize runtime and guarantee thorough internal component lubrication. Built into a highly durable frame weighing 48 kg, this engine provides an optimal power-to-weight ratio, making it an excellent power source for professional generators, high-capacity water pumps, and construction rollers.

Key Features & Benefits:

• Superior 11 HP Output: Engineered to reach a peak of 8.1 kW, offering significantly elevated power capacity for machinery requiring sustained, heavy-duty operational strength.
• Massive Torque Production: Delivers up to 25.0 Nm at lower 2200 RPM speeds, supplying the crucial rotational force needed to push through severe physical loads and dense materials.
• Industrial 442 cm³ Displacement: The large single-cylinder architecture maximizes structural durability and combustion force during long, high-intensity industrial work cycles.
• Precision Direct Injection: Utilizes an advanced diesel fuel delivery system to optimize combustion strictly, successfully lowering overall operational costs and emissions.
• Active Air-Cooled Efficiency: Integrates a forced-air management system that aggressively prevents thermal overload, allowing for consistent performance in harsh, elevated climates.
• Optimized Fluid Capacities: Perfectly balances a 4.3-liter fuel tank for extended runtimes with a 1.5-liter oil sump that ensures deep internal lubrication to reduce mechanical wear.
• Maximum Automotive Power (N - 11 HP): Represents the absolute peak threshold (8.1 kW) for short, high-intensity bursts when machinery must tackle immediate, heavy obstacles.
• Intermittent Work Power (NB - 10.1 HP): The rated 7.4 kW capacity specifically designated for fluctuating workloads, ensuring stability during tasks that require frequent starting and stopping.
• Continuous Duty Power (NA - 9.3 HP): The steady 6.8 kW marathon rating built strictly for 24/7 continuous operations, making it ideal for constant-load stationary pumps and professional generators.
