How small is the smallest engine in the world?

A Spanish engineer, Motores Patelo, spent 2,500 hours making the world's smallest 32-cylinder car engine. It has a 32-cylinder mini metal engine that is only 1 foot long. When you look at it running on the desktop, you can't imagine that it is a purely handmade work.

Nowadays, the new slot-type small engine after extreme slimming is quite light and small, only half the size of a desk. A few days ago, MTU Frie in GermanyDrichshafen and Detroit Diesel Engine Company of the United States jointly developed the world's most compact and lightest armored equipment diesel engine.

Watching TV, it is said that the smallest engine is a molecule composed of several (not many) atoms, several of which make up the ratchet, turning the thermal motion of the rotor composed of the other atoms into a one-way rotation.? I don't know the smallest generator.

There are the largest engines and the smallest engines in the world. This engine is called a nano engine, which has been reported in an American magazine.

The small two-stroke gasoline engine is hot and weak

1. In summary, the two-stroke engine is very hot not long after starting, which may be caused by heat dissipation system problems, piston wear, ignition system problems, or insufficient engine oil or poor quality. If you can't determine the problem, you can contact professional technicians for diagnosis and repair.

2. Another reason is that the throttle valve is faulty. The above two problems will cause engine shaking and unstable speed.

3. The single-bar two-stroke gasoline engine is weak for more than ten minutes. Check whether there is any abnormal noise and learn to distinguish the abnormal noise that belongs to the reasonable sound. It is difficult for ordinary car owners to distinguish which are faulty abnormal noise and which are reasonable abnormal noise. When I went to the repair shop to test the abnormal sound of the vehicles, only nearly 20% of the vehicles really had problems.

4. Your stupid and loyal engine power is relatively small. If you can, pay attention to it. Whether the water temperature is caused by the water circulation system, the engine power is not good. I hope my answer will be helpful to you. Thank you [Car questions, ask the car master. 4S store professional technician, 10 minutes to solve.

5. Serious shortage of coolant: If the car owner does not check and find and add the coolant in time, this is easy to cause the engine to overheat, and the engine will be very hot after a while, which should not only be a problem of lack of coolant, but also very likely to be caused by leakage of the water tank pipeline and serious lack of coolant.

6. The engine of the stroke is generally forced air cooling, and the mixed oil must be burned.

The structure of the engine?

1. Fuselage group, composition: cylinder head, cylinder block and crankcase Function: As the assembly base of various engine mechanisms and systems, it is the skeleton that supports and fixes the crank connecting rod mechanism and other devices, and the relevant parts of the tractor chassis form the frame of the tractor.

2. The two major mechanisms are the crank connecting rod mechanism and the gas distribution mechanism, which are used to realize the combustion and exhaust of the engine.The five major systems are start-up system, ignition system, fuel system, lubrication system and cooling system, which are used to provide conditions for the normal operation of the engine.

3. The automobile engine consists of two mechanisms and five systems, namely the fuselage and crank connecting rod mechanism, gas distribution mechanism, fuel supply system, ignition system (diesel engines usually do not have this system), cooling system, lubrication system and starting system. The fusele and crank connecting rod mechanism are composed of the fusele group, piston, connecting rod, crankshaft and flywheel, etc.

4. The engine is composed of seven large pieces, each of which has its own functions.

5. Engine structure principle The structure composition of the automobile engine is composed of five major systems and two major mechanisms. Different mechanisms and systems use different accessories, namely: the crank connecting rod mechanism is composed of the body, connecting rod, crankshaft, flywheel and piston.

6. Hello: The engine is mainly composed of two mechanisms and five systems. The fuselage and crank connecting rod mechanism, gas distribution mechanism, fuel supply system, ignition system (diesel engines usually do not have this system), cooling system, lubrication system, start-up system.

How does the gasoline engine work?

1. Their working principle is as follows: The working principle of gasoline engine: The four-stroke gasoline engine first mixes air and gasoline into a good mixture in a certain proportion, and then sucks the mixture into the cylinder during the intake stroke. The mixture is compressed and ignited to produce heat energy.

2. Their working principle is as follows: the working principle of gasoline engine (gasoline engine): the four-stroke gasoline engine willThe air body and gasoline are mixed in a certain proportion to form a good mixture, which is sucked into the cylinder during the intake stroke. The mixture is compressed and ignited to generate heat energy.

3. The working principle of the gasoline engine is to generate kinetic energy by burning the fuel in the cylinder to drive the reciprocating movement of the piston in the engine cylinder, which drives the connecting rod connected to the piston and the crank connected to the connecting rod to make a circular movement around the center of the crankshaft to output power.
