Diesel engine combustion oil gas intelligent control proportioning device

Abstract

The invention relates to a diesel engine combustion oil gas intelligent control proportioning device which comprises a turbocharger and an intercooling system connected with the turbocharger, wherein the intercooling system is also connected with a gas inlet pipe of an engine; the gas inlet pipe of the engine is connected in parallel with a group of gas supplement pipes; and an electromagnetic valve, a first gas bag, a pressure regulating valve, a second gas bag and an air compressor are additionally installed on the gas supplement pipes in sequence. By adopting the invention, the gas satisfaction degree needed for instantaneously accelerating the engine is improved, and the smoke intensity is greatly reduced; by utilizing a light-proof smoke intensity method for measurement, the reduction rate of the smoke intensity is 30 percent to 60 percent, other effluents are correspondingly reduced, and the accelerating power is obviously improved. In terms of the angle of social effect, the invention reduces pollutants discharged by urban buses, improves the urban living environment and really realizes environmental-friendly and low-carbon living environment.

Description

technical field [0001] The invention relates to a device for automatically controlling and adjusting the ratio of oil and gas, in particular to a device for intelligently controlling the ratio of diesel engine combustion oil and gas for the starting acceleration and rapid acceleration process of diesel engines used in vehicles, ships and generator sets. Background technique [0002] At present, the international community attaches great importance to the control of diesel engine exhaust. The main research directions are: (1) fuel control measures, through ① using alternative fuels; ② improving petroleum smelting technology; ③ developing new diesel additives; eliminating sulfur in diesel, Reduce the aromatic components in fuel, reduce the content of unsaturated hydrocarbons in diesel, improve the quality of diesel, and solve the problem of exhaust emissions from raw materials. (2) In-engine purification technology, using electronic control technology, through optimizing the d...

Problems solved by technology

[0004] But in the research of method (2), following technical problem appears: a, variable cross section turbocharger, utilize variable cross section to adjust the pressure of exhaust gas and thereby increase the rotating speed of supercharger, but the possibility in this technology The material requirements for variable cross-section are very high, which cannot be completed in China at present

b. Compressors driven by multi-stage supercharging or DC motors are used in foreign countries. First, the mechanism is very complicated, the manufacturing is difficult and the cost is high. Second, the DC power consumes a lot of power and the starting current is very large.

c. Some domestic units use the high-pressure gas from the brake gas tank to supplement the gas, which will affect the brake safety after repeated use.

d. The electric supercharger is used, but the supercharging effect is not obvious. The reasons are: 1. The rotation speed of the electric supercharger is far less than that of the exhaust gas turbocharger, and the pressure of the gas after supercharging is lower than that of the exhaust gas The gas pressure after the turbocharger is supercharged; 2. There is still a lag effect in the start-up time of the electric supercharger
