What faults have you encountered when using an electric cargo tricycle? Today, Jiuzhi briefly analyzed the reasons for the idling jitter of the cold car and the reasons for the poor acceleration of the cold car, and taught you how to troubleshoot the fault of the electric cargo tricycle. We hope it can be helpful to you, and you will not be at a loss when you encounter a situation.
If the cold idling jitter of the electric dump truck and the rapid jitter of the hot car exist at the same time, the fault of the rapid jitter of the hot car should be eliminated first. To determine whether it belongs to jitter, you should observe whether the pointer of the engine tachometer of the electric dump truck swings, or read the engine speed in the data block, because the engine of the electric dump truck will experience vibration of the engine speed of the electric dump truck, especially if the feet are too hot. Automatic transmission when put into forward gear.
The reasons for the idling jitter of a cold car are as follows:
1. Mechanical failure of the electric dump truck engine. For example, the pressure of each cylinder is not uniform.
2. The intake system is faulty, such as air leakage in the intake pipe. Too much carbon deposits on the intake valve and intake pipe, too much dirt on the inner wall of the throttle valve and intake pipe, etc.
3. The engine management system of the electric dump truck is faulty. For example, water temperature, intake air temperature signal is incorrect, line failure, etc.;
4. The ignition system is faulty. For example, there is too much carbon deposition on the spark plug or the gap is incorrect, the high-voltage line, the distributor cover is leaking, and the ignition coil is damaged.
5. The oil supply system is faulty. For example, the injection nozzle is not tightly closed or blocked due to excessive colloidal carbon deposition inside the nozzle.
Poor cold acceleration
Although the user manuals of many electric dump truck manufacturers indicate that the vehicle can be started without preheating after a cold start, the author believes that it is beneficial to preheat the engine of an electric dump truck for 3-5 minutes after starting, because it can reduce the mechanical strength of the engine. Wear, for small-displacement vehicles, the engine of the electric dump truck can have sufficient power when starting. It is a wrong driving method to start a cold car with a big gas pedal. The acceleration car that appears at this time can be avoided. If the cold car starts slowly with gas, the car is a dry fault.
The reasons for the poor acceleration of the cold car are:
1. The engine mechanical system of the electric dump truck is faulty. For example, low cylinder pressure leads to a decrease in engine power, which is more prominent in a cold car state, and excessive carbon deposits on the intake valve and intake pipe.
2. Too much carbon deposits on the intake valve and intake pipe, which causes the injected gasoline to be adsorbed by the carbon deposits and cannot enter the combustion chamber.
3. The engine management system of the electric dump truck is faulty. For example, the water temperature, the intake air temperature signal is incorrect, the line failure, etc.
4. The ignition system is faulty. For example, there is too much carbon deposition in the spark or the wrong time, high-voltage lines, leakage of the distributor cover, bad ignition wire system, etc.
5. The oil supply system of the electric dump truck is faulty. For example, the injection nozzle is not tightly closed or blocked due to excessive colloidal carbon deposition inside the nozzle.
