Embodiment Construction

[0015] The technical solution of the present invention is illustrated below, but the technical solution of the present invention is not specifically limited, and equivalent replacements and obvious deformations of its technical features should fall within the protection scope of the present invention.

[0016] Refer to attached figure 1 , the CNG device for the internal combustion engine of the present embodiment comprises the CNG gas cylinder 1 connected to the air inlet of the engine 7 through the charging valve 2, the high-pressure solenoid valve 4, the pressure reducer 6 and the sequential injection nozzle 9 in sequence, and is provided with a vehicle-mounted ECU14. The vehicle-mounted ECU controls the opening of the injection nozzle through the speed sensor 3 for collecting the rotational speed of the main shaft of the engine, the temperature sensor 15 for collecting the temperature of the water tank, and the position sensor 16 for the opening of the throttle. Said inflat...

Abstract

The invention discloses an internal-combustion engine CNG device, comprising a CNG gas bottle which is connected into an engine inlet port by a gas charging valve, a high-pressure electromagnetic valve, a decompressor and a sequential injection nozzle in sequence, the internal-combustion engine CNG device is provided with a vehicular ECU, and the vehicular ECU is used for controlling the opening aperture of the injection nozzle by a speed sensor for acquiring the rotation speed of a main shaft of an engine, a temperature sensor for acquiring the temperature of a water tank and a position sensor for acquiring the opening aperture of an accelerator. Based on the technical schemes, the internal-combustion engine CNG device can burn natural gas and diesel, and has good energy-saving and emission-reducing effects.

Description

(1) Technical field [0001] The invention relates to a CNG device for an internal combustion engine, in particular to the energy-saving transformation of a diesel engine to achieve the purpose of energy conservation and emission reduction, and belongs to the technical field of dual-fuel internal combustion engines. Among them, CNG refers to Compressed Natural Gas, that is, compressed natural gas. (2) Background technology [0002] Current dual-fuel internal combustion engines are mainly gasoline and natural gas mixed fuel gasoline engines. Due to the differences in fuel ignition modes, load characteristics and combustion processes of gasoline engines and diesel engines, those skilled in the art have not yet solved the difficult problem of diesel engine gas. A dual-fuel motor tricycle disclosed by the Chinese Intellectual Property Office No. 02214323 invention patent is the exploration of those skilled in the art in solving this technical problem, but it only provides the so-c...
