Problems solved by technology

The biogas and gasoline dual-purpose engine disclosed in this document only adjusts the ignition advance angle when the fuel is changed. The adjustment amount of the ignition advance angle for different components of biogas is fixed, and it is difficult to adjust the ignition advance angle for different biogas.
[0006] In addition, there is no technical content in the prior art to equip an electronic control unit (ECU) for biogas (or natural gas) and gasoline dual-purpose engines

Embodiment Construction

[0021] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation of the present invention, and are only used as examples. At the same time, the advantages of the present invention will become clearer and easier to understand.

[0022] The biogas (or natural gas) / gasoline dual-purpose engine of the present invention has a cylinder block, a gasoline supply unit, a biogas (or natural gas) supply unit and an ECU electronic control unit. Such as figure 1 As shown, the gasoline supply unit includes a fuel tank, oil pump, oil pipeline and injector; the biogas (or natural gas) supply unit includes a biogas (or natural gas) storage chamber, an electronically controlled pressure regulator, an air filter, a mixer, and an electronic throttle.

[0023] The engine electronic control unit ECU is the core of the whole system. It collects the analog signal or digital signal transmitted b...

Abstract

A biogas (or natural gas) / gasoline dual-purpose engine provided with an ECU comprises a gasoline supply unit, a biogas (or natural gas) supply unit, a cylinder block and the ECU. Two spark plugs capable of allowing simultaneous high-energy ignition and arranged in certain distance are arranged on a cylinder head of the cylinder block, a setting unit of the ECU can be used for setting fuel categories and spark advance angles under a startup working condition, and optimum spark advance angle data aiming at gasoline or biogas (or natural gas) with different methane content are stored in an RAM of the ECU. The biogas (or natural gas) / gasoline dual-purpose engine has the advantages that the optimum spark advance angles can be independently chosen corresponding to the biogas (or the natural gas) with the different methane content.

Description

technical field [0001] The invention relates to a biogas (or natural gas) / gasoline dual-purpose engine, in particular to a biogas (or natural gas) / gasoline dual-purpose engine with an electronic control unit (ECU), and belongs to the technical field of engines. Background technique [0002] Biogas (or natural gas) has been paid more and more attention to as a clean energy source, and the biogas (or natural gas) engine developed by using it as the fuel of the engine is very popular. However, unlike gasoline engines with sufficient gasoline supply, the supply of biogas (or natural gas) is often difficult to guarantee. When the supply of biogas (or natural gas) is insufficient, people expect gasoline to be used as fuel. Therefore, People begin to study gasoline, biogas (or natural gas) dual-purpose engine. At present, many experts, scholars and technicians have explored gasoline engines converted to biogas (or natural gas) and gasoline dual-purpose engines. [0003] Biogas (o...
