Abstract

The invention provides a natural gas management system used for a natural gas engine. The natural gas management system comprises an integrally-cast flat body. An on-off valve element installing space for installing an on-off valve element and a pressure stabilizing / reducing valve element installing space for installing a pressure stabilizing / reducing valve element are arranged at the right end of the front side of the body. A temperature controller installing space for installing a temperature controller is arranged at the left end of the front side. A natural gas filter device installing space for installing a natural gas filter device is arranged at the middle position. A metering valve installing space is arranged on the upper side. A heat exchanger installing space for installing a heat exchanger and a natural gas circulation path used for circulation of natural gas circulation and formed through machining are arranged on the rear side. According to the natural gas management system used for the natural gas engine, on the premise that the natural gas supply quality is guaranteed, the structure is simplified, air resistance is reduced, and reliability and safety of the natural gas engine and the whole vehicle driving comfort level are improved.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to a natural gas management device for natural gas engines. Background technique [0002] As people pay more and more attention to environmental protection, green travel has become an advocated way of life. The closely related means of transportation - cars are also becoming more and more environmentally friendly. [0003] Natural gas is the clean energy with the largest reserves in the world. It is used in automobile engines, and the spark ignition mode has been widely used. At present, the fuel supply system of a common natural gas engine is composed of multiple parts connected in series and gas pipes. This connection form has complex pipelines, many joints, bloated structure, large airflow resistance, slow gas supply response, high risk of leakage, and high safety. Low. Taking a certain type of natural gas engine as an example, there are gas cut-off valves,...
