The smooth operation of the ship really depends Main Engine working conditions, required regular maintenance and planned on all Main Engine parts. Availability of spare parts are quite above board also plays a major role in the smooth maintenance and repairof Main Engines.rnBased on the experience on board less than perfect combustion Main Engine performance can interfere with the parent. The influence of fuel carburetion imperfect can affect the high temperature of the exhaust gas, so that the power generated RPM will decrease and will be the ship's speed will be slowed down. This hampers the smooth operation of the ship and the company, fact checking of a few things that can be known to cause fuel injection valve ca be combustion as injector nozzle becomes blocked/ clogged by dirt.rnThe above events can be inferred, interference with corporate operations injector can affect main engine. Fuel injector valve maintenance in accordance with running hours should be considered to prevent damage caused by the imperfect working of the fuel injector valve.
