Diesel start six bogey
Low temperatures in winter can make starting a diesel engine quite challenging. Many operators, in an attempt to speed up the process, resort to improper methods that can actually harm the engine. It's crucial to understand that there are six common mistakes people make when trying to start a diesel engine in cold weather.
First, never use an open flame to heat the fuel tank. This practice not only damages the paint on the vehicle’s body but also risks melting plastic fuel lines, leading to leaks. Worse still, the rapid expansion of gases inside the tank could cause an explosion, potentially resulting in serious damage or even injury.
Second, avoid using an open flame to bake the bottom of the fuel tank. This method can shorten the engine’s lifespan and cause the oil to degrade, reducing its lubricating effectiveness.
Third, don’t start the engine without coolant. If you run the engine first and then add cold water later, the sudden temperature change can cause thermal stress, leading to cracks in the engine block or cylinder head.
Fourth, never pour oil directly into the air intake. This can lead to carbon buildup on the piston and piston rings, significantly reducing the engine’s service life.
Fifth, don’t remove the air filter to start the engine with fire. Doing so allows unfiltered air to enter the engine, increasing wear on internal components like valves and cylinders.
Lastly, avoid forcing the engine to start without preheating. Using external power to crank the engine before it's properly warmed up can cause dry friction between the crankshaft and bearings, possibly leading to a seized engine.
To start a diesel engine properly in cold weather, follow these steps: Use winter-grade diesel with a low freezing point. Preheat the engine oil and fuel using hot water. Add approximately 70°C hot water as coolant to help warm up the system. Also, preheat the fuel tank, injectors, high-pressure lines, and engine block using charcoal or hot water before attempting to start the engine. These precautions will help protect your equipment and ensure smoother operation in cold conditions.
