摘要： PROBLEM TO BE SOLVED: To drive an existing high pressure fuel pump accurately by an engine having no cam shaft by transmitting the rotation of a crank shaft to a pump input shaft of the high pressure fuel pump by a power transmission device through a power transmission converting part and providing an oil filling part in the power transmission converting part. SOLUTION: A V type 6 cylinder 2 cycle engine of an outboard motor has a cylinder body which is arranged longitudinally in a condition in which 6 cylinders are horizontally put to form V bank when viewed in a plan. A high pressure fuel pump 37 is arranged on a top face of this engine. The rotation of a driven pulley 44 which transmits the rotation of a crank shaft through a drive belt is transmitted to a pump input shaft 37e through a power transmission change part consisting of a vertical shaft 114, bevel gears 113, 117, and a horizontal shaft 110. The high pressure fuel pump 37 is driven due to the rotation of this pump input shaft 37e. Moreover, an oil filling part 119 is provided in the power transmission converting part to prevent the occurrence of vibration and noise due to the wear of the gears and a bearing.

摘要： PROBLEM TO BE SOLVED: To separate the water in a fuel without installing a water separation device separately and independently by installing a water separation and storing means for separating and storing the water in the fuel in an auxiliary fuel tank. SOLUTION: A water storing room 32b is connectingly formed on the bottom wall 32a of a pump room 32. This water storing room 32b is constituted so that a cylinder body with a bottom is insertingly connected to the opening formed below the filter 33 of the bottom wall 32a and one part of the bottom wall inner surface of a vapour separator tank 22 is fallen in downward largely. As the inner volume of the vapour separator tank 22 is sufficiently large for the consumed fuel amount at an engine side, the fuel returned from the engine side in this vapour separator tank 22 and the fuel flow speed when the fuel dupplied from a main fuel tank side is moved to the high pressure fuel pump 24 side are extremely slow. Therefore, the water in the fuel is separated surely from the fuel by its own weight and accumulated in the water storing room 32b along the inner surface of a bottom wall 31a slanted in a front side and the corrosion of an iron part is prevented.

摘要： PROBLEM TO BE SOLVED: To retain a fuel injection amount to a correction value regardless of the deterioration of an air-fuel ratio sensor, by detecting an air-fuel ratio in exhaust, and also measuring response time that this air-fuel ratio is set from a lean side to a rich side, and correcting a fuel injection amount so that the response time is shortened on the basis of a degree of response time delay. SOLUTION: The fuel injection type cooled two-cycle V-six-air cylinder crankshaft vertical engine of an outboard motor, is equipped with a controller such as an air-fuel ratio detector 70 for inputting detected signals from various kinds of sensors showing the conditions of the outboard motor and a ship. When fuel injection is controlled, an air-fuel ratio(A/F) in exhaust is detected by the air-fuel ratio detector 70, and also a fuel injection amount is calculated on the basis of a target air-fuel ratio (stoichiometric air-fuel ratio). Also, response time that the detected air-fuel ratio is set from a rich side to a lean side is measured, and the fuel injection amount is corrected so that the response time is shortened on the basis of the degree of this response time delay, and in the case that the response time becomes a predetermined value or more, the upper and lower limits of the fuel injection amount are set.

摘要： PURPOSE: To avoid sudden rising of engine speed by detecting the opening of an accelerator cam mechanism, when the operating quantity of an accelerator operating piece is less than a specified value corresponding to a pickup point, by an accelerator cam opening detecting means. CONSTITUTION: When an accelerator lever is opened, a throttle wire 60 acts to the arrow direction and turns an accelerator cam 63 to the arrow direction through a cam lever 61. The accelerator cam abuts on the sphere 68a of a throttle lever 68 and throttle valve shafts 66a, 66b, 66c turn a throttle valve 15. The turning angle is detected by a throttle valve opening sensor 41 and controls fuel injection and ignition timing on the basis thereof. In this case, before the accelerator cam abuts on the sphere 68a, accelerator cam opening is detected by a cam opening sensor 64 provided by the shaft 63a and, based on this, the ignition timing making the lag angle quantity gradually smaller is controlled as the accelerator cam opening approaches the pickup point opening.
