摘要

本文提出一個新穎的引擎氫氧混合供應系統，應用電解純水的方法，產生氫氧混合氣體，達到去除引擎積碳的功效。此引擎氫氧混合供應系統包括：氫氧電解槽、氣／水分離器、氣體冷卻器、真空壓力調節器、散熱風扇、以及電源控制器。其汽油引擎的燃燒過程，由於燃燒溫度高，且油氣停留的時間極短，所以無法完全避免有部份氣化及燃燒不完全的物質，這些氣化不完全的部分，形成像油漆狀的膠質，附著於引擎進氣汽門表面稱為進氣汽門積碳。而燃燒不完全的焦炭物質，則附著在引擎燃燒室內的汽缸頭與汽缸蓋，此稱為引擎燃燒室積碳。如噴油嘴產生積碳時，則形成阻塞，因此汽油無法完全霧化，使得未氣化的油滴，則漸漸在進氣汽門因高熱下由膠狀物質產生碳化，所以當進氣汽門嚴重積碳時，造成引擎的輸出馬力降低，因而導致耗油量增加，而且所排放出來的廢氣因燃燒不完全而造成空氣污染。因此供給系統連結汽車進氣歧管，導入引擎燃燒室，當汽油與氫氧混合氣體燃燒時，由於氫氧混合氣體會再提高燃燒室溫度，進而燃燒積碳，並隨著排放而達到清除積碳效果。使用廢氣分析儀監測汽車一氧化碳排放量，在固定電流下的引擎氫氧混合供應系統，會穩定的產生氫氧混合氣體，供給燃燒室，再藉由一氧化碳（CO）、碳氫化合物（HC）及氮氧化物（NO_X）的排放明顯降低，證實本系統效能。

In this paper, we propose a fundamentally brand-new system, Engine Oxyhydrogen gaseous mixture supply system, to get rid of engine carbon deposition by using the method of water electrolysis. Specifically, after dissolving the water, it will produce a mixed hydrogen and oxygen gas to clean the engine carbon deposition. The main functions of this system includes gas/water separator, gas cooler, vacuum pressure regulator, cooling fan and power source controller. In normal situations, during the gasoline engine burning process, an engine will produce an extremely high temperature. This when combined with the very short time of the gas which can be availably burned in the engine will inevitably come up with some partly gaseous and incompletely burned materials like a sticky liquid covering the surface of the air intake valve, an unwanted phenomenon called air intake valve carbon deposition. In fact, when this happens, some incompletely burned coke materials will also cover the cylinder head and cylinder cover of the engine combustion chamber, another phenomenon called combustion chamber carbon deposition. Specifically, when the injection valve is covered with the residual carbon, it will not be able to atomize the gasoline completely, causing some un-atomized drops of gasoline. This will eventually lead to lowering the output horse power of the engine, which again causes the increasing consumptions of gasoline as well as air pollution because of the incompletely burned exhausts. To tackle these problems, we use this system to connect to the intake manifold of an engine so that the mixed hydrogen and oxygen gases can go into the chamber of the engine. When they meet the burning gasoline, they will increase the burning temperature of the gasoline. This will burn and clean the residual carbon by sending it out through the process of exhaustion. To prove the effectiveness of this system, we also use an Exhaust Gas Analyzer to monitor the carbon monoxide emissions. Specifically, when connected to this system, the combustion chamber works smoothly and the carbon monoxide , Hydrocarbons and Nitrogen oxides emissions decrease significantly.
