摘要： A fuel injection control device for outboard motors optimizes the air-fuel ratio when trim is applied to the outboard motor, especially those with two-cycle engines. In such an outboard motor, engine speed, throttle setting, engine boost pressure, engine temperature, intake air temperature, and/or other variables are detected and a basic fuel injection volume determined. Fuel is supplied to each of the engine's cylinders according to the detected values. A trim angle detecting means is used to indicate trim angle. During low-speed operation, the trim angle is detected, and the magnitude of a change in the trim angle is calculated. The magnitude of the change in the trim angle is used to estimate the residual fuel volume within the engine. The estimated value is used to apply correction to the basic fuel injection volume following the change in the trim angle. As a result, during low-speed operation, an optimal air-to-fuel ratio can be obtained when the trim of the outboard device is changed.

摘要： A tilt-up handle for an outboard motor is placed in the upper rear portion of an engine cover accommodating an engine and has an outside-air inlet opening rearwardly in the boat traveling direction. The outside-air inlet protrudes rearwardly in the boat traveling direction from a rear wall of the engine cover so as to be substantially aligned with an imaginary vertical line overlapping with the rear wall of the engine cover when the outboard motor is viewed in profile. The tilt-up handle prevents moisture from entering and allows outside air to enter an engine cover without compromising air intake.

摘要： In an outboard motor having a fuel-injected two-cycle engine, engine speed, throttle setting, engine boost pressure, and/or other variables are detected and a basic fuel injection volume determined. Fuel is supplied to each of the engine's cylinders according to the detected values. When the engine is stopped, information about the operating conditions of the engine before the engine was stopped are saved in a memory of a controller. These saved values represent the residual fuel volume left in the engine's cylinders at a subsequent start-up of the engine. The saved values are used to correct the basic fuel injection volume determined at start-up by the controller.
