Why Does Audi Burn Engine Oil?
1 Answers
Audi burns engine oil due to the following reasons: 1. Audi's engines are high-compression-ratio engines. The advantages of high-compression-ratio engines are high power, large torque, and low fuel consumption, which result in oil burning. 2. Audi pursues an even higher compression ratio. Once the compression ratio increases, it indicates that the temperature inside the engine cylinders will rise, and higher temperatures will cause engine oil to deplete. Below is relevant information about Audi's oil burning issue: Reasons why Audi burns more oil than other cars 1. Audi's engines are high-compression-ratio engines. The advantages of high-compression-ratio engines are high power, large torque, and low fuel consumption. Audi's engine compression ratio is higher compared to Japanese and Korean cars. 2. The physical structure of direct-injection engines differs from traditional port-injection engines. Fuel is directly injected into the cylinders through high-pressure atomization by the injectors inside the cylinders. This process is different from port-injection engines, so during atomization, some fuel is directly sprayed onto the cylinder walls, diluting and burning the oil, which also causes a small amount of oil consumption. 3. Audi's manufacturing process for cylinders and cylinder blocks differs from other brands. Audi engines do not adopt the mainstream all-aluminum structure but use an aluminum cylinder head and cast-iron cylinder block structure, meaning the parts below the valves are made of cast iron. Generally, Japanese brand engines are almost entirely made of aluminum, and there are few reports of oil burning issues.
