Problems solved by technology

[0004] However, although many inventions have been disclosed for dual fuel injectors and injectors with variable orifices, problems related to manufacturing complexity and fuel leakage have prevented many of the inventions from mass production
Furthermore, few previously disclosed techniques provide the ability to selectively and collectively direct inject different fuels without mutual interference between the operations injecting the different fuels
Therefore, the prior art requires great control complexity, especially for synchronizing the operation of the twin needles normally used for dual fuel injection

Embodiment Construction

[0028] exist Figure 1 to Figure 4 The first embodiment is shown in . figure 1 The needle valve is shown in the seated position.

[0029] We have shown one implementation here. Alternatives based on the same operating mechanism are readily given to those skilled in the art. The embodiments shown herein should be considered as examples and not as limiting the scope of the invention. Other embodiments having the same key characteristics are considered to be within the scope of the invention. For example, the first fuel and the second fuel are the same fuel, so the injector becomes a single fuel injector. The following features are considered as key features of the invention.

[0030] Option A:

[0031] A fuel injector comprising:

[0032] Nozzle body (6) comprising channels (603, 562, 602) for the fuel; an inner cylindrical bore for accommodating a compound needle valve (I) capable of moving up and down in the axial direction ; at least one set of fuel injection outlets ...

Abstract

A fuel injector has means to directly inject one type of fuel or two types of fuels collectively with fuel ratios on demand. Once being used as a single fuel injector, the injector can enable injection rate shaping. Once being used as a dual fuel injector, the injector can tailor fuel properties on demand. The fuel injector has the capability to enable tailored chemical and thermal-physical fuel properties to enable high efficiency clean combustion for different engine loads and speeds.

Description

technical field [0001] The present invention relates to a fuel injector, a fuel injection method, and an internal combustion engine. Specifically, the present invention discloses a fuel injector that can co-inject two types of fuel differentiated by at least one parameter of pressure, molecular structure, or thermodynamic phase, thereby having the ability to tailor fuel characteristics on demand, and discloses An engine using at least one such fuel injector is disclosed, which engine may be a spark-ignition engine or a compression-ignition engine. Background technique [0002] This application claims priority to US Provisional Application 62651590, filed April 2, 2018. [0003] Description of Related Art - In recent years, progress has been made in advanced combustion modes such as homogeneous charge compression ignition (HCCI) combustion, reactivity controlled compression ignition (RCCI) and premixed charge compression ignition (PCCI). However, there are still many proble...
