An anti-dribble valve is a component of a fuel injection system used for diesel engines. Its main function is to provide precise timing of fuel injection, particularly at the end of the injection time. If fuel was allowed to 'dribble' after the main phase of injection, this fuel would be too late for good combustion and so would be only partially burned as visible exhaust soot. Although simple, the valve has several functions: * A one-way check valve * A 'pop' valve * An anti-dribble valve The valve was introduced on injection equipment by the firm of CAV Bosch in the 1930s. == Check valve == A check valve allows flow in only one direction and prevents back-flow. This maintains the injector pipe as full of fuel, as any leakage here would require the pipes to be primed again before the engine could be restarted. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Anti-dribble valve」の詳細全文を読む スポンサード リンク
