| YC6MK Series Marine Engine |
| Yuchai YC6MK350 has proven to have high torque & power with low fuel consumption. |
| YC6MK350 has better acceleration and has lower fuel consumption than previous engine. |
| It uses mechanical fuel pump and injectors are easy to maintain. Currently customer is using B20 biodiesel. |
| Customers are satisfied with the performance of Yuchai Marine Engine. |
| Yuchai Marine Genset 180kW at 1,500rpm at 50Hz. |
| Yuchai Marine Genset has been working under long hours and proven to be durable, reliable and fuel efficient. |
| Current fuel used is biodiesel B20. |
| YC6T Series Marine Engine |
| This cargo vessel carries timber from Malaysia to Thailand. |
| Previously, customer has been using using NTA855 Cummins (350PS at 1800rpm) x 2units. With cargo, the maximum speed is about 4-5 knots. |
| Now the vessel can cruise at speed of 9 knots when fully loaded, after changing to YC6T480C (480PS at 1800rpm) x 2 units. |
| Customer has shorten journey duration from 30 hours to 22 hours with equal amount of fuel consumption. |
| With failure of water pump and no pre-alarm or shutdown feature, the used marine engine has failed & costly to repair. |
| It has been replaced with new Yuchai YC6T540C (540PS at 1800rpm) Marine Engine x 2 units. |
| Maximum power for old engine was 1000hp at 2100rpm, but it could only run at 1800rpm at that time. |
| Using the same gearbox and propeller, it reached the same speed at 1800rpm at 15 knots when fully loaded. |
| Fuel consumption has reduced from 800L/day to 600L/day. Saving – 200L/day. |
| YC6K Series Marine Engine (Commonrail) |
| YC6K Series is fully electronic control marine diesel engine. It uses BOSCH high pressure common rail fuel injection system. |
| It has high reliability with overhaul period to be able to reach 30,000 hours. |
| When compared to mechanical engines, it is about 10% more fuel efficient. Its lightweight and compact design allow it to fit in tight space. |
| It has allow Oceanic Blue to be one of the fastest diving boat in Phuket. |
| YC6TD Series Marine Engine (EUPI) |
| Introduction to YC6TD Marine Engine, featuring Electronic Unit Pump Injection (EUPI). Using ECU to allow accurate and timing injection of fuel for optimal performance and efficiency. |
| Unlike Commonrail engine, it does not use high-pressure commonrail fuel pump, thus it does not require the best fuel to run and is relatively cheaper to maintain.Unlike Commonrail engine, it does not use high-pressure commonrail fuel pump, thus it does not require the best fuel to run and is relatively cheaper to maintain. |
| The new ferry using Yuchai YC6TD650 (650PS at 1800rpm) x 2 units and used Cummins NTA855 (350PS at 1800rpm) x 1 unit to power. |
| It has been successfully commissioned and customer is satisfied with Yuchai YC6TD650 Marine Engine. |
| Without load, it can reach top speed of 10.4 knots. YC6T650 at 1800rpm. NTA855 at 1450rpm. |
| YC6CL Series Marine Engine |
| Replacing the old engines with Yuchai YC6CL1035 x 2 units, the ship has able to improve its top speed from 10.5 knots to 14.0 knots. |
| With full load, the customer runs at optimal speed of 750rpm at 11.5 knots which result only 70L per hour per engine. |
| Currently the customer is using B20 biodiesel. Customer is very satisfied at the performance and fuel saving achieved. |
