What happens when the engine coil is broken?

There are three manifestations of a faulty engine ignition coil: 1. At idle, the vehicle body shakes noticeably; 2. While driving, when the RPM is below 2500, the vehicle body shakes noticeably with weak acceleration; 3. Upon opening the engine hood and observing the running engine, noticeable shaking of the engine is observed. Causes of ignition coil failure: 1. A short circuit in the spark plug can directly cause an increase in current in the ignition coil, leading to a short circuit; 2. An open circuit in the spark plug (excessive carbon buildup) can increase the load on the ignition coil, causing it to fail after prolonged overload operation; 3. A short circuit to ground in the high-voltage wire can cause an increase in current in the ignition coil, leading to a short circuit.

What are the reasons for a diesel engine failing to start when hot?

There are several reasons why a diesel engine may fail to start when hot: 1. Fuel: There is air or excessive moisture in the fuel supply system. 2. Component failure: Blockages in the pipelines or filters; wear of the fuel injection pump plunger; breakage of the fuel injection pump plunger spring, resulting in no pressure in the fuel injection pump. Leakage in the intake or exhaust valves; loose cylinder head nuts or damaged cylinder gasket. Here is more information about diesel engines: 1. Definition: A diesel engine is an internal combustion engine that uses diesel as fuel. Diesel engines are compression ignition engines and are often referred to as Diesel engines after their main inventor, Rudolf Diesel. 2. Advantages: They offer high torque and good fuel economy. The working process of a diesel engine shares many similarities with that of a gasoline engine, with each working cycle also going through the four strokes of intake, compression, power, and exhaust.

Is Automotive Antifreeze Conductive?

Automotive antifreeze is conductive. The main components of antifreeze are 50% pure water, 40% methanol, and 10% other substances, giving it conductive properties. Functions of Antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and providing year-round protection against scale and corrosion. Antifreeze Replacement Cycle: For vehicles that operate for extended periods, such as taxis, high-quality antifreeze should generally be replaced annually. For vehicles with shorter operating times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which can reduce the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-lasting antifreeze can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the antifreeze, it should be replaced promptly, and the system should be cleaned. Can Different Antifreeze Brands Be Mixed? It is essential to use the same brand of antifreeze. Different brands may have varying production formulas, and mixing them could lead to chemical reactions between the additives, rendering them ineffective.
