Fuel supply system for e.g. multi-cylinder diesel engine, has pressure detecting unit detecting fuel pressure in fuel supply channel, and evaluating unit evaluating air quantity mixed in fuel from detected pressure value
摘要
<p>The system has a fuel supply channel to supply fuel to an exhaust boss (26) of a high pressure fuel pump (4) through an interior of a low pressure fuel pump (5) and a pressurization chamber (31) of the high pressure pump. A control device (10) has a pressure detecting unit to detect a fuel pressure in the supply channel, and an evaluating unit to evaluate an air quantity mixed in the fuel from the detected fuel pressure value.</p>
