What Happens When There Is Excessive Oil in the First Bank Cylinder Combustion System?
2 Answers
The first bank cylinder combustion system having excessive oil can cause engine oil to enter the combustion chamber, leading to engine damage. The reason for excessive oil may be due to a faulty cylinder head gasket in a water-cooled engine, allowing coolant to enter the cylinder, which increases the oil volume. Below is an introduction to related content: 1. The vehicle's combustion system: The function of the vehicle's combustion system is to ensure the fuel required for the engine's combustion. The combustion system is generally part of the vehicle's powertrain system, which refers to the engine generating heat by burning fuel in the combustion chamber to propel the vehicle forward. 2. The vehicle's powertrain system: The powertrain system transmits power from the crankshaft, flywheel, clutch, transmission, driveshaft, differential, and reducer to the wheels. When vehicle fuel operates within the combustion system, it consumes a portion of the power. During high-speed driving, this portion of power is used to overcome air resistance, effectively reducing vehicle fuel consumption.
As a little helper in the auto repair shop, I've seen the scenario of excessive oil in the first row of cylinders several times. That causes the car to emit black smoke during acceleration, with an extremely strong gasoline smell, and the engine shakes violently while driving, as if it's convulsing. Even worse, the spark plugs may get clogged with oil, making ignition difficult, leading to a sudden drop in engine power and a rapid increase in fuel consumption. Over time, carbon layers build up on the cylinder walls, affecting sealing and even accelerating piston ring wear. The fix is simple: first, check the oil level, and if it's too high, use a specialized oil extraction tool to remove the excess. It's recommended that car owners pay attention to oil level checks during regular maintenance and confirm it before long trips to avoid sudden breakdowns on the highway.
