Problems solved by technology

The domestic LNG-diesel dual-fuel engine natural gas supply system has been applied to low-power equipment and related reports, but the high-power system is still in its infancy, and its application in mines, railways and other fields is still blank
Moreover, the existing patents have not provided a complete natural gas supply system for high-power LNG-diesel dual-fuel engines, nor have they realized the whole process of multi-directional monitoring of the engine operation process, which is not conducive to the safe and stable operation of the engine

Abstract

The invention discloses a natural gas supply system for a high-power LNG-diesel oil dual-fuel engine. The natural gas supply system comprises a storage system, a supply system and a control system, wherein the storage system is connected with the supply system; the supply system is simultaneously connected with the storage system and the engine; and the control system communicates with the storage system, the supply system and the engine respectively. The natural gas supply system disclosed by the invention has obvious economical and social benefits, can save a lot of fuel cost for an enterprise and also can greatly reduce the exhaust pollution of the engine.

Description

technical field [0001] The invention relates to the field of engines, in particular to a natural gas supply system for a high-power LNG-diesel dual-fuel engine. Background technique [0002] At present, the high-power engines used in mining trucks, train locomotives or ships are diesel engines. Not only is the operating cost high, but the exhaust pollutants contain a large amount of nitrogen oxides, particles, sulfides, etc., which are difficult to treat and cause environmental pollution. [0003] US EPA Tier 4i (Interim) and Tier 4 (Final), which took effect in 2011 and 2014-2015 respectively, set stricter emission standards with no exemption requirements for large mining engines. Engine companies must research new technologies to enable engine emissions to meet stricter regulatory requirements without affecting the equipment, operation and production costs of complete machine manufacturers and end users. [0004] my country's railway transportation is one of the largest ...
