Background
The development of a dual-fuel low-speed diesel engine among marine diesel engines has been long, and a low-speed diesel engine using only natural gas as a secondary fuel has not been able to fully satisfy the market demand. Among the secondary fuels, Liquefied Petroleum Gas (LPG) is also an economical and resource-intensive fuel, and particularly for LPG carriers, the use of LPG as the secondary fuel for diesel engines has natural advantages.
A low speed diesel engine using LPG (liquefied petroleum gas) as fuel injects liquefied petroleum gas into the combustion chamber of the diesel engine, so this type of diesel engine is referred to as the LGIP engine.

The LPG pipeline, the discharge pipeline and the leakage detection pipeline have no special requirements on the cleaning degree, and only the conventional cleaning maintenance is required in the pipeline.
The pipeline inside LGIP host computer gas module A is more complicated, and the oil inlet has three routes to be respectively: high pressure oil, low pressure oil, sealing oil; the oil outlet has twelve paths: hydraulic oil, control oil and sealing oil; and a liquid fuel gas inlet and outlet and a leak detection channel are arranged between the two parts.
