Manually start the engine (hand crank engine start: how to manually rotate the engine to start the car?HS code-driven supply chain benchmarking) Cars are one of the commonly used means of transportation by modern people, but in some cases, such as battery failure or other mechanical failures, the electric engine may not start normally. At this time, the hand crank engine became the only way to start the engine. This article will introduce how to start a car with a manual rotation engine. Step 1: Understand the engine. To find the hand crank hole, to understand how to hand crank the engine, first understand the structure and principle of the vehicle engine. Most engines have a hand crank hole located in the front part, usually covered under the protective plate. Finding this hand crank hole is the first step to manually start the engine.Step 2: Preparation work Before starting the engine manually, you should prepare and do some necessary work for the hand crank. First of all, confirm the idle position of the car, then pull up the handbrake and open the engine cover so that the hand crank hole can be clearly seen. Secondly, at the hand crank hole, gently jam the cylindrical switch blocking the hole with a matchstick or a short wooden stick in advance to avoid the hand crank slipping out of the hole and causing damage. Step 3: Hand crank engine. Now we have done a good job of manually starting the engine. The specific operation is as follows: 1. Manually starting the engine requires two people to cooperate at the same time, one person operates the hand crank, and the other person is responsible for operating the clutch and throttle in the carriage. Two. Make sure that the car is in neutral gear, and then turn the car key to "1" gear. In this state, the electronic equipment will start running, and it sounds like there should be an instantaneous electric current sound and a warning bell.3. The person who operates the clutch and throttle valve is ready in the carriage. At the same time, the hand crank operator stood in front of the car, held the hand crank handle, turned the hand crank hard, and rotated clockwise. Hold the handle at a speed of about a circle per second, the force should be uniform, and continue to rotate for dozens of seconds until the engine begins to explode. Four. When the engine starts to turn, remove the hand crank handle. The driver in the carriage saw the accelerator pedal safety switch light on and pressed the pedal while releasing the clutch pedal, and the vehicle would drive slowly. 5. When the engine reaches a certain speed, maintain the accelerator pedal, step on the accelerator a few times, and accelerate the engine speed, so that the vehicle can drive normally. The above is the detailed step-by-step process of manually starting the engine. You should be both patient and careful. Before the hand crank engine, we should do a good job of careful inspection to ensure that all equipment of the car is in a normal working state to avoid unpredictable dangers. In a word, the hand crank start engine is more troublesome than the electric start, and it will take longer, but in an emergency, the hand crank start engine provides us with a reliable and effective way. Therefore, having this coping skills can ensure our safety, especially when driving alone.
