1. Whether the flow can be adjusted can be divided into: variable pump and quantitative pump. The output flow can be adjusted as a variable pump as needed. The flow cannot be adjusted as the quantitative pump.

First look at the most common engine parameter -engine displacement. The engine displacement is the sum of the operating volume of each cylinder of the engine, which is generally represented by liters (L). The operating volume of the cylinder refers to the gas volume swept by the piston from the top to the lower point, also known as a single cylinder displacement, depending on the cycle diameter and the piston itinerary. The engine displacement is a very important engine parameter. It can more represent the size of the engine than the cylinder diameter and the number of cylinders. Many indicators of the engine are closely related to the exhaust volume. Generally speaking, the greater the displacement, the greater the output power of the engine.

Engine (Engine) is a machine that can convert other forms into mechanical energy, including internal combustion engines (to rehabilitation engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is suitable for both power occurrence devices or the entire machine (such as gasoline engines, aviation engines) including power devices. The engine was first born in the UK, so the concept of the engine also originated from English. Its original meaning refers to the "mechanical device that generates power."

Some people call the engine as the engine. In fact, the hair engine is only a part of the entire engine, but it is the core part of the entire engine. People are constantly developing various types of engines, but no matter what kind of engine, its basic prerequisite is to burn some fuel to generate power. Therefore, electric motors with electricity as the source of energy do not belong to the scope of engine.
