What does Aowei 11-liter mean?
2 Answers
Aowei 11-liter refers to the engine's displacement. Displacement: Displacement refers to the exhaust volume, which is the volume swept by the piston from top dead center, also known as single-cylinder displacement, and depends on the cylinder bore and piston stroke. The displacement of an internal combustion engine is the sum of the working volumes of all cylinders, usually expressed in liters (L). Working Principle: Exhaust volume is the gas expelled by the piston from one stroke to another during the engine's operation when a specific cycle delivers air into the cylinder. Theoretically, during the exhaust stroke, the exhaust gas in the cylinder should be completely expelled by the piston, hence it is often referred to as 'piston displacement'.
I often read car magazines and have a good understanding of truck engines. The Aowei 11-liter refers to the 11-liter displacement diesel engine installed on FAW Jiefang Aowei trucks. Simply put, displacement is the space inside the engine cylinders where fuel can be burned, and 11 liters means it's quite large, suitable for heavy-duty transportation. Such a large displacement can deliver high power, around 400 horsepower, making it easy to haul tens of tons of cargo uphill and stable for long-distance highway driving. However, it has higher fuel consumption, so drivers should pay attention to controlling speed for better fuel efficiency. This series of trucks is popular in China's freight industry, commonly seen in construction sites or long-haul logistics, known for reliability and durability. During maintenance, it's important to regularly check the air filters and cooling system to prevent blockages that could affect performance. Choosing this type of truck depends on load requirements; if frequent heavy hauling is needed, it's a worthwhile investment.
