V32/40 Low-load operation and the Recommendation

After 500 hours of continuous operation with liquid fuel at a low load in the range of 20% to 25% of the full load, the engine should be ran-in again. The engine must be operated at > 70 % of the full load for some periods in order to reduce the deposits in the cylinders and exhaust gas in turbocharger.

[Maintenance for System component]

The LO low pressure alarm is one of the alarm parameters for the lo system for engine start-up (warm) rather than for the Pre LO pump. If the alarm sounds or the pressure is lower than that of other engines, check the condition of the engine and the system components.

Many parts including pump, cooler, filter and valves, are assembled into the LO system, which can also cause pressure drops due to coolers and filters. These parts have different inspection periods based on engine operating condition, fluid status, and used hours. Therefore, based on users’ requirement, they should be registered on PMS list, and many different factors should be observed. If there are any difference from original status, LO system should be inspected and managed.

[The role of the filter as an Engine Protection]

The Filter in the case of the V32/40 engine is a 30 micron Auto backflushing filter. It takes out most of the particles in the oil which are larger than approx 30 micron at the widest point of the narrowest cross section.

[The role of the purifier as the Lubricant Oil Cleaning]

The role of the purifier is actual cleaning of the lubricant oil heat of the oil is sufficient to facilitate it. (min. approx. 95 deg.). The particles cleaned out will go into the sludge tank. The size of remaining dirt particles after the purifying stage would normally and nominally be smaller than 5 micronmeter. This means that the purifiers should run always when the engines are running. If it is not done, any dirt particles in the lubricant oil system smaller than approx. 30 micrometer could be re-circulated again and again.

Key factor in reducing component wear: Centrifugal by-pass oil filter

Oil is the life-blood of the engine and clean oil is essential if an engine is to operate efficiently throughout its working life.

Emission reduction technologies such as exhaust gas recirculation have been shown to increase the level of contaminant, especially soot in the lubricating oil. Soot particles are sub-micron in size. Soot is a hard pro-wear particle. High soot levels within a lubricating oil have been shown to be responsible for accelerated wear of critical engine components. Traditional full flow and by-pass filters are unable to remove soot contaminant as it is too small to be captured. Centrifugal filters are proven to be effective at removing soot.

Centrifugal filter has proved to be the key factor in reducing component wear whilst increasing the oil and engine life cycle and provides a cleanable, low maintenance and environmentally friendly solution throughout the life span of the engines.

The following advantages are obtained with the Centrifugal by-pass oil filter.

l  Reducing critical component wear of bearings, pistons, piston rings…etc.

l  Lower maintenance cost of ship owner.

l  Maintaining oil cleanliness for longer periods.

l  Cleanable, environmentally friendly waste disposal.

l  Prevent accidents by contamination of lube oil such as camshaft cam and bearing shell damage…etc.

Please note that a centrifugal filter installation cannot replace the necessary function of the lube oil purifier. and this solutions are available as retrofit for all GenSets.

STX ENGINE has been finally selected as localization developer for an electronic fuel injection diesel engine

After STX ENGINE has been finally selected as localization developer for an electronic fuel injection for a multi launch rocket system Chunmoo, it signed an agreement with KRIT (The Korea Research Institute for Defense Technology Planning and Advancement) for a support project for the localization of weapon parts.

As the diesel engines in Chunmoo currently operated by the ROK Army have been discontinued or have reached their end of life, there was a need to develop an alternative engine. Accordingly, the development of the electronic fuel injection was promoted as a support project for localization of weapon parts (aka localization of strategic weapon parts).

It is expected that the development of this engine will enable it to stably field the weapons and cope with changes in weapon systems by resolving issues incurred by discontinuation of existing engines. Moreover, the development of weapon’s major parts is expected to contribute to revitalizing K-defense exports by eliminating factors that hinder the export of combat vehicles and engines.

In 2021, STX Engine was selected as a localization developer for 1000-horsepower diesel engine for the K9 self-propelled howitzer which is one of the most prestigious weapons of the ROK Army. After completing engine prototype production and performance testing three years after the start of development, this paved the way for STX Engine to export to countries with restricted exports, such as countries in Middle Eastern and Egypt.

Lee Sang-Soo, the CEO of STX Engine, said “STX Engine is the only defense engine manufacturer in Korea with 45 years of defense engine manufacturing experience and technical know-how, and now it is growing into one of the most trusted companies in the world after fulfilling our customers’ due date, quality service and technical supports. STX Engine will do its best to localize and develop electronic fuel injection for tracked vehicles within the schedule so that they can help to stabilize forces and to grow together with a number of small domestic partners.”
