Novel turbocharger system

Abstract

The invention belongs to the technical field of fuel injection systems of internal combustion engines, and particularly relates to a novel supercharger system. The novel supercharger system comprisesa supercharger body, a piston and a return spring, wherein the supercharger body is internally provided with the piston, the piston is pressed on a sealing conical surface inside the supercharger bodythrough the return spring to form a sealing intersection line to separate a second containing cavity and a first channel are separated, the piston is internally provided with a second channel which communicates a first containing cavity with the second containing cavity in the supercharger body, the supercharger body is provided with a third channel which communicates a containing cavity in an LNG tank with the second containing cavity, the supercharger body is provided with a fourth channel which communicates a third containing cavity with an external low-pressure environment. The supercharger system has the beneficial effects that compressed natural gas gasified by the LNG tank is adopted as a gas source, the system is attached to the LNG tank and does not need an additional gas sourceand a power source and can quickly and effectively adjust the pressure in the LNG tank, and in addition, the supercharger has simple overall structure, good reliability and low production cost throughmechanical structure control.

Description

technical field [0001] The invention belongs to the technical field of fuel injection systems of internal combustion engines, and in particular relates to a novel supercharger system. Background technique [0002] In the current market, among internal combustion engine vehicles that use natural gas as fuel, natural gas is carried on the vehicle in two ways: compressed natural gas (CNG) and liquefied natural gas (LNG). Compressed natural gas (CNG) is gaseous natural gas at high pressure, usually 1 volume converted to 200 standard volumes of natural gas. Liquefied natural gas (LNG) is natural gas in liquid form, usually 1 volume converted to 600 standard volumes of natural gas. CNG vehicles have insufficient continuous driving ability and are suitable for small vehicles such as taxis. Compared with CNG vehicles, the continuous driving capacity of LNG vehicles is greatly increased, and medium and heavy trucks also have enough space to store equipment. [0003] In vehicles us...

AI Technical Summary

Problems solved by technology

The LNG tank pressurization system currently on the market is a set of independent working systems. When controlling the pressure in the LNG tank, the fluctuation range is large, the reliability is poor, and the structure of the booster system is very complicated, the cost of production and processing is high, and there are many leakage points. , which is not conducive to the promotion of LNG combustion technology
