However, it's possible that it's due to faulty glow plugs, which is more likely in cold weather. The car's combustion chamber may not acquire enough heat if the glow plugs aren't working properly. As a result, there may be difficulties with igniting the fuel, resulting in the engine failing to start. When you observe a sign like this, you should check your glow plugs.

In order for the combustion process in diesel engines to work, significant compression rates are required. Furthermore, the fuel should be present in sufficient quantities, and the fuel injection should take place at the appropriate moment. Nonetheless, your car's combustion chamber may require temperatures of approximately 232°C to ignite. However, if your glow plugs are defective, the engine chamber will not reach this temperature.

Reduced Fuel Efficiency - Vehicle fuel efficiency is affected by the kind of fuel used and the temperature. As a result, some people may believe that glow plugs are harmless. Glow plugs, on the other hand, serve an important function in supplying extra heat to the combustion chamber. As a result, when the glow plugs fail, the requisite temperature is no longer accessible.

As a result, the car's exhaust begins to spew black smoke. Such a notice should not be ignored, and the diesel glow plugs should be checked for functioning.

White Smoke - In addition to the black smoke emitted by your vehicle's exhaust, you may observe white smoke. It happens when there isn't enough heat in the combustion chamber to burn the fuel. Please be aware that when the weather is cold, white smoke is prevalent. It continues until the engine begins to warm up. Another source of this white smoke might be an air-filled fuel system with insufficient compression. However, this is one of the signs of a malfunctioning glow plug control module.
