Cummins NTC 350 Engine Specs
The Cummins NTC 350 engine is a powerful and reliable diesel engine that has been widely used in various applications, including heavy-duty trucks, construction equipment, and marine vessels. This article will provide you with detailed specifications of the Cummins NTC 350 engine, including its engine configuration, engine oil specs, and service intervals.
Engine Configuration
The Cummins NTC 350 engine is a 14.0-liter, six-cylinder engine that operates on a four-stroke combustion cycle. It features an inline configuration, meaning that all cylinders are arranged in a straight line. This configuration offers several advantages, including improved engine balance and easier maintenance access.
The engine is equipped with a turbocharger, which helps increase its power output by compressing the incoming air before it enters the combustion chamber. This results in improved engine performance and fuel efficiency.
Engine Oil Specs
Using the correct engine oil is crucial for maintaining the performance and longevity of the Cummins NTC 350 engine. Here are the recommended engine oil specifications:
- Oil Type: Cummins recommends using high-quality diesel engine oil that meets the CES 20076 or CES 20077 specifications. These oils are specifically formulated to provide optimal lubrication and protection for the engine components.
- Viscosity Grade: The recommended viscosity grade for the Cummins NTC 350 engine is SAE 15W-40. This grade ensures proper oil flow and lubrication in various operating conditions.
- Oil Capacity: The engine has an oil capacity of approximately 38 liters (10 gallons). It is important to check the oil level regularly and maintain it within the recommended range.
Service Intervals
Regular maintenance is essential for keeping the Cummins NTC 350 engine in top condition. Here are the recommended service intervals for key engine components:
- Oil Change: The engine oil should be changed every 15,000 miles or every 250 hours of operation, whichever comes first. Regular oil changes help remove contaminants and ensure proper lubrication.
- Oil Filter Replacement: The oil filter should be replaced during each oil change. This helps remove impurities from the oil and prevents them from circulating through the engine.
- Air Filter Replacement: The air filter should be inspected regularly and replaced as needed. Cummins recommends replacing the air filter every 12,000 miles or every 200 hours of operation.
- Fuel Filter Replacement: The fuel filter should be replaced every 12,000 miles or every 200 hours of operation. This helps maintain fuel quality and prevent contaminants from entering the engine.
- Coolant Replacement: The engine coolant should be replaced every 30,000 miles or every 500 hours of operation. This helps prevent overheating and corrosion within the cooling system.
| Component | Service Interval |
|---|---|
| Oil Change | Every 15,000 miles or 250 hours |
| Oil Filter Replacement | During each oil change |
| Air Filter Replacement | Every 12,000 miles or 200 hours |
| Fuel Filter Replacement | Every 12,000 miles or 200 hours |
| Coolant Replacement | Every 30,000 miles or 500 hours |
Following these service intervals and using the recommended engine oil will help ensure the optimal performance and longevity of your Cummins NTC 350 engine. Regular maintenance is key to keeping your engine running smoothly and efficiently.
