Diesel start six bogey
Low temperatures in winter can make starting a diesel engine quite challenging. Some operators may resort to improper methods to get the engine running quickly, but these practices can seriously damage the engine and even pose safety risks. It's crucial to understand that starting a diesel engine in cold weather involves six common mistakes that should be avoided:
First, never use an open flame to heat the fuel tank. This not only damages the paint on the vehicle's body but can also ignite plastic fuel lines, leading to oil leaks. In extreme cases, it could cause explosions due to gas expansion inside the tank, potentially damaging the engine and endangering lives.
Second, avoid using an open flame to bake the bottom of the fuel tank. This practice can shorten the engine’s lifespan and cause the oil to degrade, reducing its lubricating properties.
Third, never start the engine without cooling water. Adding cold water after the engine starts can cause thermal shock, leading to cracks in the engine block or cylinder head.
Fourth, don't add oil through the air intake pipe. This can lead to carbon buildup on the piston and piston rings, reducing the engine's efficiency and service life.
Fifth, never remove the air filter to start the engine with fire. This allows unfiltered air to enter the engine, increasing wear on internal components like valves and cylinders.
Sixth, avoid forcibly starting the engine with another power source without preheating. This can cause dry friction between the crankshaft and bearings, potentially leading to the crankshaft seizing.
So, how should you properly start a diesel engine in cold weather? First, use diesel fuel with a low freezing point, such as winter-grade diesel. Second, preheat the engine oil and fuel using hot water. Third, use hot water around 70°C as coolant to help warm up the engine before starting. Finally, preheat the fuel tank, injectors, high-pressure lines, and engine block using charcoal or hot water before attempting to start the engine. These steps will help ensure a safe and smooth start in cold conditions.
