Problems solved by technology

The biogas engine is the key equipment for biogas energy conversion in the field of biogas power generation technology. Domestic research on biogas engines began in the early 1980s. Some units have carried out research on the structural modification of biogas engines, mainly for biogas , The research on diesel dual-fuel engines still has a certain gap in technology compared with foreign countries, mainly reflected in the operation reliability problems of biogas engines such as insufficient power, high gas consumption, poor emission and difficult starting, which bring inconvenience to users. It is a technical bottleneck that restricts and affects the development process of biogas power generation industry

Embodiment Construction

[0017] The present invention will be further described below:

[0018] The present invention comprises the following steps:

[0019] (1) Gas injection control: To accurately provide the quality of biogas to the engine, it is determined by the speed-density method, and the mathematical relationship is as follows:

[0020]

[0021] In the above formula: m cyl The air mass flow rate entering the cylinder per working cycle; η V is the charging efficiency of the cylinder; V cyl is the cylinder volume (m 3 ); n is the engine speed (r / min); p m is the intake pipe pressure (kPa); Tm is the intake pipe temperature (K);

[0022] (2) Ignition control: The ignition advance angle is an important parameter to determine the performance of the engine. In order to accurately provide the ignition time in the operation of the biogas engine, the internal combustion engine combustion theory, combined with related theories, can obtain the ignition advance angle. The mathematical relationshi...

Abstract

The invention discloses a methane engine ignition control method. Compared with the prior art, under dual pressure of relieving energy and environmental crisis, the renewable low-pollution biomass energy is increasingly concerned by various countries in the world, wherein the methane energy becomes the priority developing emphasis in the energy construction due to wide distribution, low construction cost and prominent comprehensive benefits; meanwhile, the excellent development tendency is laid for research and development of methane engines; and the popularization and application value is achieved.

Description

technical field [0001] The invention relates to an engine control method, in particular to an ignition control method for a biogas engine. Background technique [0002] In the current severe situation of global energy and environment, the use of high technology to convert renewable biomass energy into clean high-quality gas and liquid fuels as an alternative energy source for fossil fuels, and to apply them in electricity, transportation, etc., has been accepted by the world countries' attention. The biogas engine is the key equipment for biogas energy conversion in the field of biogas power generation technology. Domestic research on biogas engines began in the early 1980s. Some units have carried out research on the structural modification of biogas engines, mainly for biogas , The research on diesel dual-fuel engines still has a certain gap in technology compared with foreign countries, mainly reflected in the operation reliability problems of biogas engines such as insu...
