汽车起动机原理与故障排查英文双语对照

汽车起动机是汽车发动机启动的重要组成部分，也是汽车正常运行的关键。了解汽车起动机的原理和常见故障排查方法，可以帮助车主更好地维护汽车，避免因起动机故障导致的不便和损失。

汽车起动机概述

汽车起动机，又称起动电机或启动器，是利用电动机驱动机械装置，通过旋转发动机曲轴，使发动机达到工作转速，从而启动汽车发动机的设备。它通常安装在发动机的转向齿圈上，与发动机曲轴相连，通过起动电瓶提供的电能来实现发动机的启动。

汽车起动机工作原理

当驾驶员转动钥匙启动汽车时，电瓶会提供电流给起动机。起动机的电动机会转动一个齿轮，在接触到发动机曲轴的飞轮齿条时，它们会相互锁合，推动曲轴旋转，带动活塞上下运动，最终启动发动机。一旦发动机正常运转，起动机会自动脱离，以免发动机和起动机相互损伤。

汽车起动机常见故障及排查方法

1. 电瓶电量不足：当车辆启动困难或发动机转速缓慢时，可能是电瓶电量不足。此时需要检查电瓶是否需要更换，以及相关连接线路是否正常。

2. 起动机齿轮磨损：起动机齿轮长时间磨损会导致与飞轮的齿条无法有效连接，导致启动困难。此时需要检查起动机齿轮的磨损程度，如有必要及时更换。

3. 电路故障：起动机的电路故障可能导致无法启动。可通过检查电路连接是否良好，电瓶是否给起动机提供足够电流来确定问题所在。

4. 起动机电机故障：起动机电机本身的故障也会导致汽车无法启动，需要通过专业工具检测电机的工作状态。

总的来说，定期检查起动机的工作状态，保持电瓶的良好电量，及时更换磨损的部件，是保证汽车起动机正常工作的关键。

感谢您的阅读，通过这篇文章，希望能帮助您更好地理解汽车起动机原理，并在日常使用中更好地维护和保养汽车。

Car starter is the main component that car engine starts, also be the key that the car runs normally. The principle that understands car starter and common breakdown platoon investigate a method, can help a car advocate safeguard a car better, avoid the inconvenience that causes because of starter breakdown and loss.

Car starter is summarized

Car starter, say to start electric machinery or starter again, it is to use electromotor drive machine, pass crankshaft of motive of transmit coming back, make engine reachs working rotate speed, start the facility of car engine thereby. It is installed normally in engine turn to tine to be encircled, be linked together with engine crankshaft, the electric energy that provides through starting storage battery comes to those who realize engine start.

The car starts mechanic to make a principle

When the driver turns the key starts a car, storage battery can offer electric current to give starter. The dynamoelectric opportunity of starter is rotational a gear, when the flywheel rack of crankshaft of engine of bring into contact with, they can be locked up each other close, drive crankshaft to rotate, drive a piston to move up and down, start engine finally. Once engine runs normally, starting opportunity is broken away from automatically, lest engine and starter are injured each other.

Common breakdown and platoon check car starter method

1.Storage battery n is insufficient: When the car difficulty that start or engine rotate speed are slow, the likelihood is inadequacy of storage battery n. Right now need checks storage battery to whether need to change, and relevant link line is normal.

2.Starter gear wears away: Starter gear wears away for long can bring about the rack with flywheel to cannot join effectively, cause the difficulty that start. Need those who check starter gear to wear away right now degree, if be necessary,change in time.

3.Circuit breakdown: The circuit breakdown of starter may be brought about cannot start. Can join through checking circuit good, whether does storage battery offer enough electricity to decide the problem is in to starter.

4.Start trouble of aircraft electric machinery: The breakdown of itself of starter electric machinery also can bring about a car to cannot be started, need detects through professional tool the working status of electric machinery.

As a whole, check the working status of starter regularly, maintain the good n of storage battery, change in time tatty component, it is the key that makes sure car starter works normally.

Thank you read, carry this article, the hope can help you understand car starter principle better, be safeguarded better in be used daily and maintain car.
