Through the intuitive observation of the engine, we understand the working principle of various engines!
1, single-cylinder engine
Single-cylinder engine is the simplest of all engines, it has only one cylinder, is the basic form of the engine.
Single-cylinder engine work, the crankshaft per revolution (two-stroke) or two laps (four-stroke), the mixture in the cylinder ignition combustion time, from the sound and vibration, can clearly feel the engine's work is intermittent, Exhaust gas is also "sudden" intermittent sound.
However, its simple structure, low manufacturing cost and no complicated maintenance are the best choices for small and mid-size motor scooters. .
2, twin-cylinder engine
Two-cylinder engine, refers to the engine with two cylinders, which is composed of two identical single-cylinder arranged on a body with a common crankshaft output power.
▲ horizontally opposed twin-cylinder engine
The twin-cylinder engine is suitable for both power generating units and entire machines including power units, such as gasoline engines and aero-engines.
▲ motorcycle twin-cylinder engine
Multi-cylinder engine used in car engines, motorcycles, chain saws and other low-power power machinery.
3, three-cylinder engine
Three-cylinder engine is a three-cylinder engine, the general displacement is relatively small, in order to meet the power requirements, those compact-class models are generally equipped with turbocharged version of the three-cylinder models.
The performance of the triple-cylinder engine will be better, but the sound of the engine is less pleasing, and its small size, light weight and low cost, but with a little vibration.
4, four-cylinder engine
Four-cylinder engine, also known as the four-cylinder engine, the body mainly by the cylinder block, crankcase, cylinder head and cylinder cushion and other components.
The basic principle of a four-cylinder engine is to convert the heat energy of gasoline (diesel oil) into combustion gas through a sealed cylinder to promote the work of the piston and transform it into mechanical energy.
▲ Inline engine
In-Line Engine: All cylinders are arranged side by side in a plane. Its cylinder block and crankshaft are simple in structure and use one cylinder head. The manufacturing cost is low, the stability is high, the low speed torque characteristics are good, the fuel consumption is small, the size is compact, It is widely used, but its disadvantage is its low power.
▲ V-type engine
V-type engine: the adjacent cylinder is arranged at a certain angle so that the two groups of cylinders form an included angle plane, and the V-shaped engine is viewed from the side. The V-shaped engine is small in height and length and is arranged on the car More convenient.It is easy to increase displacement and power by expanding the cylinder diameter and suitable for higher cylinder number.Currently made in the high-end models, many with V-6 cylinder engines, such as Regal, Passat and Audi A6, etc. .
▲ horizontal opposed engine
Horizontal opposed type: the engine piston is evenly distributed on both sides of the crankshaft, left and right in the horizontal direction.
Horizontally to reduce the overall height of the engine, reducing the length, reducing the center of gravity of the vehicle, driving a more stable vehicle, the engine installed in the center line of the vehicle, both sides of the piston torque offset each other, greatly reducing the vehicle in motion Vibration, engine speed is greatly improved, reducing noise.
5, star engine
A star engine is a type of piston engine in which the cylinders are arranged in a star around the crankshaft, with an odd number of cylinders.
Prior to the advent of jet engines, piston aircraft engines mostly adopted a star design. Due to their strong survivability in the short battlefield of the crankshaft and the small space occupied by their compact structure, the aircraft engines were widely used by aircraft carriers.
6, rotor engine
The rotor engine relies on the expansion pressure generated by the combustion of the mixture to obtain a rotational force that acts on the side of the rotor to urge one of the three faces of the triangular rotor toward the center of the eccentric shaft. Force under the force of force, one is to the center of the output shaft centripetal force, the other is to make the output shaft rotation tangential force.
Rotor engine to cancel the useless linear motion, and therefore the same power rotor engine size smaller, lighter weight, and lower vibration and noise, has greater advantages.
7, Westinghorse engine
The Quasi engine is an improved engine based on a rotor engine. Unlike the three-rotor version of a typical rotor engine, Quincy uses a four-part chain-type rotor that has four strokes that take into account the four-stroke engine and rotor The advantage of the engine is a new type of engine that is small, horsepower, low speed, high torque and can use a variety of new energy sources.
8, Stirling engine
The Stirling engine is powered by the heat expansion of the gas and the compression of the cold, an external combustion engine that continuously burns the fuel and uses vaporized expanded hydrogen (or helium) as the motive gas to move the piston. Cold air chamber cooling, repeated this cycle.
