Electronic control fuel oil injection type outboard engine

Abstract

The invention discloses an electronic control fuel oil injection type outboard engine. The electronic control fuel oil injection type outboard engine comprises a warping mechanism driven by a hydraulic system and an ECU control module. The engine is provided with a matched fuel oil system. The hydraulic system and the fuel oil system are both controlled by an electric control system in an integrated manner. The fuel oil system comprises a fuel oil tank, a fuel oil pump, a high-pressure fuel oil pump and electronic oil injection nozzles, all of which are sequentially connected through a fuel oil pipe. The electronic oil injection nozzles are arranged on the engine. The part, between the fuel oil tank and the fuel oil pump, of the fuel oil pipe is further provided with an oil filter cup. Themultiple electronic oil injection nozzles are connected in series through a fuel oil common rail. The electronic control system at least comprises a storage battery, a magnetor, spark plugs and a plurality of sensing control elements. The engine is provided with the multiple spark plugs. The spark plugs are electrically connected through a high-voltage pack. The high-voltage pack is connected with a start relay. The output end of the storage battery is connected to the start relay through a circuit. The high-voltage pack is further connected to the magnetor through a rectification voltage regulator, and the magnetor is further connected with the storage battery. The storage battery is connected with a start motor through a power line, and the output end of the start motor is connected with a flywheel shaft of the engine.

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...

Moreover, due to the unevenness of the river bottom during the operation of the hull, there are many protruding reefs and sundries located in Hanoi, so in order to prevent the outboard unit from hitting the sundries and sundries when the ship is running at high speed, the outboard The engine needs to be tilted to avoid being damaged by the impact, but if you are a little careless, the outboard engine will also be damaged due to hitting reefs and debris

At present, most of the outboard motors are lifted by manual operation, which is inconvenient to lift. At the same time, it is extremely inconvenient to put down the outboard motor when it is not needed.
