Product Overview
The CM6D28C series Marine Diesel Engine consists of two professional models: CM6D28C.353 20 (Main engine) and CM6D28C.350.20 (Auxiliary Engine). Engineered specifically for marine scenarios, both models adopt a 6-cylinder in-line layout, paired with water-cooled in-cylinder direct injection and turbocharging technology. With certifications from CCS (China Classification Society) and IMO (International Maritime Organization), the series fully complies with global mainstream marine power standards, providing reliable power support for inland and coastal vessels.
The main engine is optimized for the core propulsion needs of vessels, delivering stable high power at 1800r/min to meet the navigation requirements of fully loaded cargo ships and engineering vessels. The auxiliary engine is tailored for on-board auxiliary power systems such as power generation and hydraulic equipment, operating efficiently at 1500r/min. Both models share the same compact size and consistent technical design, making them an ideal choice for small and medium-sized vessel power configuration and refitting projects.
Operation Guide
Pre-start Inspection
Check the oil level of the lubricating oil: Ensure that the oil level is between the upper and lower limit marks of the oil dipstick; if it is insufficient, make up the specified model of marine Diesel Engine oil in time.
Check the coolant level: Confirm that the coolant in the water tank is sufficient, and check whether the pipeline has leakage.
Check the Fuel quantity: Ensure that the diesel oil meets the marine use standard, and the fuel tank has sufficient fuel.
Check the electrical system: Verify that the battery voltage is normal, and the circuit connection is firm without loosening.
Start-up Operation
Turn on the power switch of the engine control panel, and confirm that the instrument indicators are normal.
For the main engine: Adjust the throttle to the idle position, press the start button, and the engine will start at low speed. After the oil pressure and water temperature reach the normal range, gradually increase the speed to the rated 1800r/min.
For the auxiliary engine: Ensure that it is connected to the corresponding auxiliary equipment, press the start button, and the engine will run stably at 1500r/min; it is strictly forbidden to run beyond the rated speed without permission.
Operation Monitoring
During the operation of the engine, regularly check the readings of the instrument panel, including oil pressure, water temperature, fuel consumption, etc. If the parameters exceed the normal range, stop the machine for inspection in time.
Listen to the running sound of the engine. If there is abnormal noise such as knocking and friction, shut down immediately to avoid mechanical failure.
For the main engine, pay attention to the matching with the vessel's propulsion system, and avoid sudden acceleration and deceleration during navigation to reduce mechanical wear.
Shutdown Operation
Normal shutdown: First reduce the engine speed to idle speed, run for 3-5 minutes to cool down the components, then turn off the fuel switch and press the stop button.
Emergency shutdown: In case of major faults such as oil shortage, water shortage, and severe leakage, pull the emergency stop switch immediately; after the shutdown, conduct a comprehensive inspection of the engine to eliminate the fault before restarting.
