Double-EPR electric control system for gas generator set

Abstract

The invention discloses a double-EPR electric control system for a gas generator set, which comprises a gas pressure reducing system, a gas adjusting system and an electric control unit and sensor assembly. The gas pressure reducing system comprises a gas cylinder group (1), a gas filter (2) and a gas pressure adjusting valve (3) which are sequentially connected through a pipeline. The gas adjusting system comprises a fuel electromagnetic valve (4), a gas pressure stabilizer (5), a first EPR electric control pressure regulator (6), a second EPR electric control pressure regulator (7), a first mixer (8), a second mixer (9) and an engine supercharger (11). The electronic control unit and sensor assembly comprise an ECU (electronic control unit) (15). The double-EPR electric control system for the gas generator set has the beneficial effects that high-responsiveness and high-precision closed-loop regulation control on the gas pressure and the gas inflow of the inlet of the gas engine can be realized, so that stable operation of the gas generator set under different application conditions is ensured.

Description

technical field [0001] The invention relates to the technical field of a double EPR electric control system applied to a gas generator set, in particular to a double EPR electric control system for a gas generator set. Background technique [0002] The gas generator set is built by changing the prime mover to a gas engine on the basis of the engine-generator, and the gas engine as the power output source plays a decisive role in the normal operation of the gas generator set. According to the air intake mode, the gas engine is mainly divided into: 1. Intake port pre-mixed intake; 2. Electronically controlled single-point injection intake; 3. Electronically controlled multi-point injection intake; 4. In-cylinder direct injection intake; The precise control of the gas intake amount of the intake port premixed intake directly affects the power and emission performance of the engine. With the increase of demand for power generation, gas generator sets have been widely used in va...

Problems solved by technology

For example, the low-pressure gas source generated by biomass gas limits the power generation efficiency of the gas generator set due to its low inlet pressure, resulting in poor economics for power generation applications. That is, when the pressure of the gas entering the gas generator set is low, gas power The unit is difficult to run stably
