Electronic control fuel oil injection type outboard engine

Abstract

The present invention is an electronically controlled fuel injection type outboard engine, which includes a lifting mechanism driven by a hydraulic system and an ECU control module; the engine is equipped with a supporting fuel system; the hydraulic system and the fuel system are both integrated and controlled by the electronic control system; the fuel system Including the sequential connection of fuel pipes: fuel tank, fuel pump, high-pressure fuel pump, electronic fuel injector; electronic fuel injector is installed on the engine; there is also a filter cup on the fuel pipe between the fuel tank and the fuel pump; The three electronic fuel injectors are connected in series by the fuel common rail; the electric control system includes at least a battery, a magneto, a spark plug, and multiple sensor control elements; there are multiple spark plugs on the engine; the spark plugs are electrically connected by a high-voltage package; the high-voltage package and The starter relay is connected; the output terminal of the battery is connected to the starter relay by the line; the high voltage package is also connected to the magneto by the rectifier voltage regulator; the magneto is also connected to the battery; the battery is connected to the starter motor through the power line; The flywheel shaft of the engine is connected.

Description

technical field [0001] The invention relates to the structural field of outboard motors, in particular to an electronically controlled fuel injection type outboard motor. Background technique [0002] An outboard motor refers to a propulsion engine installed on the outside of the hull, usually suspended on the outside of the transom. Outboard motors are highly integrated and easy to install, making them the first choice for small marine power. The traditional structure of the outboard motor is installed on the hull through its own clamping bracket parts, so that the outboard motor can be firmly fixed on the hull. As the main power maintenance system, the fuel and fuel injection circuit on the outboard engine play a vital role. Moreover, in order to further control the power of the outboard motor and based on energy saving, a set of fuel system and control system with multiple functions is required, which can help the control of the outboard motor. [0003] The outboard mo...
