摘要： PROBLEM TO BE SOLVED: To provide a start control device of an internal combustion engine capable of avoiding any defective start caused by vapor without unnecessarily operating a fuel pump. SOLUTION: An engine ECU stores a map specifying three zones of a high-temperature high-pressure zone (1), a low-temperature low-pressure zone (3), and an intermediate zone (2) therebetween according to the temperature and the pressure of a fuel, and the saturated vapor pressure of the fuel. When the start of an engine is requested (YES in S100), the engine ECU detects the temperature THW of an engine cooling water and the fuel pressure P (S200). If the detected values belong to the zone (2) (YES in S300), the engine ECU sets the pre-feed time T (S400), and executes a program including a step (S700) of executing the pre-feed until the fuel pressure P reaches or exceeds the desired fuel pressure threshold P (TH), and a step (S800) of starting the cranking when the fuel pressure P reaches or exceeds the fuel pressure threshold P (TH) (YES in S700).

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic relief valve in a delivery pipe capable of securely preventing the internal pressure of the delivery pipe from rising while an engine is stopped while suppressing an increase in power consumption. SOLUTION: This relief valve 28 is so formed that a valve element 44 is open according to the energization of a valve opening electromagnetic solenoid 54 to relieve a fuel from the delivery pipe 14. The valve element 44 is energized to a valve closing side by the internal pressure (delivery fuel pressure) of the delivery pipe 14. The relief valve also comprises a spring 58 always energizing the valve element 44 to the valve opening side. The energizing force of the spring 58 is set smaller than an energizing force by the delivery fuel pressure raised during engine operation on the valve element to the valve closing side. When the valve element 44 is opened and a difference between the delivery fuel pressure and a pressure in a relief passage 40 becomes approximately zero, even if the energization of the valve opening electromagnetic solenoid 54 is stopped, the valve element 44 is opened and held by the energization force of the spring 58.

摘要： PROBLEM TO BE SOLVED: To prevent the deterioration of exhaust emission at engine starting in a cylinder injection type internal combustion engine that directly injects fuel into each cylinder, caused by the fuel leakage from an injector to a body of the internal combustion engine occurring when the engine stops.
SOLUTION: ECU 30 determines which and how many cylinders 16 have an air intake valve 31 opened by a signal from a cam angle sensor 35 and a crank angle sensor 46 (S16). Then, it calculates a total injection amount ΔV required to reduce a control fuel pressure to a target pressure level based on the control fuel pressure and the temperature of cooling water (S18). The ECU 30 further calculates an injection amount Q per cylinder (S20) and injects the fuel from the injector 14 of the cylinder 16 with the air intake valve 31 judged opened (S22).
