Description

내연기관 세정윤활제 조성물Internal combustion engine cleaning lubricant composition
본 발명은 엔진 내부를 세정하기 위한 엔진 세정윤활제 조성물에 관한 것이다. 보다 상세하게는 자동차 엔진 등의 내연기관의 장기간 사용 시 엔진의 내부에 생성되어 축적되는 각종 불순물, 카본, 슬럿지, 검 등을 엔진을 해체하지 않고 엔진내부를 세정하기 위한 엔진 세정윤활제 조성물에 관한 것이다.The present invention relates to an engine cleaning lubricant composition for cleaning the inside of an engine. More specifically, the present invention relates to an engine cleaning lubricant composition for cleaning the inside of an engine without disassembling the engine of various impurities, carbon, sludge, gum, etc., which are generated and accumulated in the engine during long-term use of an internal combustion engine such as an automobile engine. .
최근 들어 가솔린 엔진, 디젤렌진, LPG 엔진 등을 장착한 일반 승용차, 버스, 트럭 및 오토바이 등이 급격하게 증가하고 있으며, 상기 엔진들은 기술 향상으로 인하여 내구성이 증가하여 종래의 엔진에 비하여 사용기간이 상당히 길어졌으나, 이에 비례하여 엔진은 장기간의 사용으로 인하여 엔진의 트로틀밸브, 분사기, 흡입밸브 및 연소실 등에 카본, 검 등의 오염 퇴적물이 생성 축적되어 엔진 운전시 엔진내부의 마찰저항의 증가시키고, 연소실 내의 기밀성 및 압축성의 저하를 초래하여 연료의 불완전 연소를 초래하는 원인이 되고 있다.Recently, general passenger cars, buses, trucks and motorcycles equipped with gasoline engines, diesel engines, LPG engines, etc. are rapidly increasing, and the engines have increased durability due to technology improvement and thus have a considerably longer service life than conventional engines. However, in proportion to the engine, due to long-term use, contaminant deposits such as carbon and gums are generated and accumulated in the engine throttle valve, injector, intake valve, and combustion chamber to increase frictional resistance in the engine during engine operation. It causes a decrease in airtightness and compressibility, which causes incomplete combustion of the fuel.
상기와 같은 문제점으로 인하여 엔진의 세정을 위하여 다음의 여러 방법을 사용하고 있다.Due to the above problems, the following various methods are used to clean the engine.
(a) 높은 rpm에서 엔진을 운전하면서 기화기의 개방 공기 트로틀에 직접 엔진 세정제 조성물을 투입하여 세정제를 연료와 혼합되도록 하여 연소공정동안 연소와 세정을 시키는 방법.(a) Combustion and cleaning during the combustion process by injecting the engine cleaning composition directly into the open air throttle of the carburetor while running the engine at high rpm to mix the cleaning agent with fuel.
(b) 엔진연료 및 세정제를 포함하는 압축용기의 사용을 포함하는 분사기의 세정방법.(b) A method of cleaning an injector comprising the use of a compressed container comprising an engine fuel and a cleaning agent.

세정 전 통상의 자동차 운전조건(주행속도 50 ~ 60Km(기어 2~3단)으로 1시간 운행하고 이후부터는 4단 운행함)에서 300 km를 주행하였다. 주행 후 엔진의 뚜껑을 열고, 엔진의 초기 상태를 육안으로 관찰하였으며, 엔진배기가스의 일산화탄소, 이산화탄소, 탄화수소의 농도 및 공기 과잉률을 측정하였다.The car was driven 300 km in normal driving conditions (driving speed 50 ~ 60km (2 ~ 3 gears) for 1 hour and 4 steps after that). After running, the lid of the engine was opened, and the initial state of the engine was visually observed. The concentrations of carbon monoxide, carbon dioxide, and hydrocarbons and the excess air ratio of the engine exhaust gas were measured.
이후, 엔진오일과 함께 실시예 및 비교예의 엔진 세정액 80 ml를 엔진에 직접 첨가한 후, 세정 전과 동일한 운전조건에서 300 km를 주행하여 세정 후 일산화탄소, 이산화탄소, 탄화수소 농도 및 공기 과잉률을 측정하였다. 또한 머플러 및 엔진내부의 상태를 육안으로 관찰하였다. Thereafter, 80 ml of the engine cleaning solution of the Examples and Comparative Examples were directly added to the engine together with the engine oil, and then 300 km was driven under the same operating conditions as before the cleaning, and the carbon monoxide, carbon dioxide, hydrocarbon concentration, and excess air ratio were measured after the cleaning. In addition, the state of the muffler and the engine inside were visually observed.
세정전과 세정후의 공기과잉률(λ:ben)은 1.00±0.02의 편차로 유지하였고, 하기 식 1 ~ 식 3에 따른 제거율을 계산하여 표 3에 나타내었다. The excess air ratio (λ: ben) before and after washing was maintained at a deviation of 1.00 ± 0.02, and the removal rate according to the following Equations 1 to 3 was calculated and shown in Table 3.
[식 1] [Equation 1]
일산화탄소 제거율(%)= (세정 전 일산화탄소의 농도 - 세정 후 일산화탄소의 농도)/세정 전 일산화탄소의 농도 × 100Carbon monoxide removal rate (%) = (concentration of carbon monoxide before washing-concentration of carbon monoxide after washing) / concentration of carbon monoxide before washing × 100
[식 2][Equation 2]
이산화탄소 제거율(%)= (세정 전 이산화탄소의 농도 - 세정 후 이산화탄소의 농도)/세정 전 이산화탄소의 농도 × 100% Removal of carbon dioxide = (concentration of carbon dioxide before washing-concentration of carbon dioxide after washing) / concentration of carbon dioxide before washing × 100
[식 3][Equation 3]
탄화수소 제거율(%)= (세정 전 탄화수소의 농도 - 세정 후 탄화수소의 농도)/세정 전 탄화수소의 농도 × 100% Hydrocarbon removal rate = (the concentration of hydrocarbon before washing-the concentration of hydrocarbon after washing) / the concentration of hydrocarbon before washing × 100
