Problems solved by technology

During this time, the work done by localized combustion resists the kinetic energy of the engine, resulting in wasted energy and overall low efficiency (wasting five to ten percent of energy)
In fact the energy efficiency of an engine with spark ignition is indeed lower, only about 30%, wasting precious fuel
(2) Pollution to the environment

Embodiment Construction

[0022] As stated in the claims of the invention, the invention is applicable to all internal combustion engines. For further description, the method, device and system of the present invention used in a four-cylinder automobile engine are only schematically illustrated below.

[0023] figure 1 A block diagram of the entire ignition system. First select a microwave source that can output the appropriate frequency, bandwidth, power, and pulse length. How to choose these parameters will be introduced later. The microwave source is driven by a repetitive pulse power supply. The pulse power supply outputs the pulse electric energy required by the microwave source at an appropriate time according to the instruction from the engine control unit. This pulsed electrical energy is converted into microwave energy by a microwave source.

[0024] Since the output pulse power of the microwave source is relatively large, an isolator is required for isolation. In this way, microwave ene...

Abstract

The invention discloses a technology that can improve the burning efficiency of internal fire engine and decrease tail gas release. It couples microwave energy that has a certain frequency into the cylinder of the engine, and fires the oil-gas mixed gas in the cylinder at a seemly moment. The frequency of the microwave is equal to the electromagnetic eigenfrequency that can cause resonance and couple the microwave into the cylinder. After firing, the left microwave acts with the plasma caused by the burning of the cylinder. Thus, the fast entire burning and more absolutely burning of the oil-gas mixture and decreasing the release of end gas would be achieved.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to a system, device and method for igniting fuels such as fuel-air mixtures using microwave energy. Background technique [0002] A fundamental component in an engine is the combustion chamber that converts the chemical energy of the fuel into mechanical energy. For a turbine engine, such as a gas turbine aircraft engine, its typical combustion chamber is in the shape of a barrel with one end open or partially or entirely composed of an annular shell. In fact, an engine can have multiple barrel combustors, or a single annular combustor. Engines can also have pre-combustion chambers and after-combustion chambers. Other engines include: rotary engines and reciprocating piston engines used in automobiles; rocket engines; ramjet engines and pulse air jet engines. [0003] The ignition of fuel in the combustion chamber depends on several factors: oil and gas temperature, type of ignite...
