Electronic fuel injection engine system and integrated control method thereof

Abstract

The invention provides an electronic fuel injection engine system and an integrated control method thereof. An electronic fuel injection engine system includes an engine, a starting and generating integrated motor, a magnetoelectric encoder, a first linear Hall sensor, a second linear Hall sensor, a third linear Hall sensor, a fourth linear Hall sensor and an integrated control device. The starting and generating integrated motor is connected with the engine. The magnetoelectric encoder is coaxially arranged with the starting and generating integrated motor and comprises a first multi-pair-pole magnet and a second multi-pair-pole magnet which are coaxially and annularly arranged, wherein the first multi-pair-pole magnet comprises m pairs of magnetic poles, the second multi-pair-pole magnetcomprises n pairs of magnetic poles, and m and n are natural numbers larger than 2 and are relatively prime. The first linear Hall sensor and the second linear Hall sensor are arranged adjacent to the first multi-pair-pole magnet, and the third linear Hall sensor and the fourth linear Hall sensor are arranged adjacent to the second multi-pair-pole magnet. The integrated control device is used forreceiving a signal from the magnetoelectric encoder and controlling the operation of the starting and generating integrated motor. Engine control, motor control and magnetoelectric encoder control are integrated, so that the real-time performance of control is greatly improved.

Description

Technical field[0001]This application relates to the technical field of electric motors, in particular to an electronic fuel injection engine system and an integrated control method thereof.Background technique[0002]The general power plant includes a starter motor system and a generator system. Traditional aircraft and vehicle-mounted engines are started by special starting devices such as hydraulic, gas turbine starters or electric starters. Among them, the electric starter uses a special motor and a variable-speed gearbox to drive the engine. After the start is completed, the starter no longer works, occupying limited space such as aircraft and vehicle systems, increasing the volume and weight.[0003]In the existing structure, the above starter motor system and power generation system are two completely independent systems, which not only take up a lot of space, but also have a complex structure. At the same time, the starter motor system is no longer used after the engine is start...

Problems solved by technology

[0003] In the existing structure, the above starter motor system and power generation system are two completely independent systems, which not only take up a lot of space, but also have a complex structure. At the same time, because the starter motor system is no longer used after the engine is started, the utilization rate is very low. It also has the disadvantages of low starting efficiency, high failure rate, and inconvenient maintenance. People have been looking for a more efficient and simpler starting solution.
