What is the biggest difference between a locomotive and an EMU? Please, thank you

Electric locomotives and diesel locomotives are commonly seen.

Its power plant is centrally installed on the locomotive, and many passenger cars without power unit are hung behind the locomotive. If the power unit is dispersed and installed on each carriage, so that it can not only have traction power, but also can carry passengers, such a passenger car is called an EMU. And EMUs.

It is a group of several self-powered vehicles and a few unpowered vehicles, which is an EMU. A powered vehicle is called a motor vehicle, and an unpowered vehicle is called a trailer. The biggest difference between the two is: speed and cost.

The biggest difference between a locomotive and an EMU is the centralization and decentralization of the power plant.

The locomotive is a centralized power vehicle, and its power plant is centrally installed on the locomotive, and the locomotive pulls multiple carriages, which belongs to the traditional train. The EMU is a power distributed vehicle, and each carriage is equipped with a power unit, which can not only pull the train, but also carry passengers.

In contrast, bullet trains have higher speed and lower cost of construction. EMU is a group of several self-powered vehicles and several unpowered vehicles to form a group of trains that can give full play to their respective advantages. EMUs have the advantages of fast speed, large passenger capacity, and flexible operation.

The biggest difference lies in the distribution of power and the tightness of the body. Secondly, there is information network technology, braking system, etc. Oh.

Locomotives are commonly known as locomotives, traction power machinery for railway transportation. There are three main categories of steam locomotives, diesel locomotives and electric locomotives, as well as gas turbine locomotives.

The locomotive on the Internet mainly refers to the meaning that there are many questions, many opinions, and very picky. Locomotives in Taiwan, China, are not allowed to go on highways, so "locomotive" is extended to mean "not on the road".

Locomotive spirit.

As an important cross-shaped railway hub in Hunan, Zhuzhou's "locomotive spirit" reflects Zhuzhou's geographical advantages and regional characteristics. The rail transit industry is the landmark industry with the fastest development, the highest technical level and the greatest development potential in Zhuzhou, and the "locomotive spirit" reflects Zhuzhou's economic and industrial advantages.

The locomotive has the symbolic meaning of "striving for the first and moving forward", and the "locomotive spirit" embodies the spirit of Zhuzhou people who dare to be the first and the municipal party committee and the municipal party committee and the city.

1. The guiding ideology of "scientific leapfrogging". "Locomotive spirit", as the expression of Zhuzhou Jingsun grinding god, is vivid and vivid, with distinctive personality and outstanding characteristics, and is easy for the public to understand and remember.

Locomotive means locomotive, because railway vehicles do not have power units, they need to be hung up to form trains, and they are often pulled by locomotives on steel rails before they can run.

In rail transportation**, many people will see the concept of locomotives, and they want to understand what kind of locomotive is, or what kind of power system is it? Let's take a look at the details of the locomotive.

Details: At the station, the marshalling of freight trains, the disintegration of nuclear spring, the pick-up and delivery of vehicles and other shunting work must be completed by locomotives.

There are many types of locomotives. According to the different uses, there are passenger locomotives with higher speed, freight locomotives with greater traction and flexible locomotives; According to the different driving forces, there are three types: steam locomotive, diesel locomotive and electric locomotive; If it is divided according to the form of the running part, there are two types of frame locomotives and bogie locomotives.

Frame locomotives mainly refer to steam locomotives, because the 3 5 pairs of moving wheelsets of steam engines are fixed on a rigid frame. Due to the large fixed wheelbase, the large sagittal distance will be generated when running on the curve, which will aggravate the friction between the wheels and rails.

Diesel locomotives generally use diesel as fuel, with high thermal efficiency, flexible maneuverability, and can run long distances after a full refueling. However, the structure is complex, and the manufacturing, maintenance and operating costs are high, and the manufacture of high-power automotive diesel engines is also limited.

The electric locomotive itself does not carry energy, its structure is relatively simpler than that of diesel locomotives, and the electrical energy can be converted from a variety of energy sources (thermal power, hydropower, wind power, nuclear energy, geothermal, solar energy, etc.), and the electrical equipment works steadily, safely and reliably.

There are many reasons for the high water temperature of the engine or even "boiling", such as damage to the compatible electronic components of the cooling system (thermostat, cooling fan), poor heat dissipation of the radiator, insufficient coolant, etc.

2. Pull over, but don't turn off the engine immediately! Because the coolant temperature is already high and the cooling capacity has reached its limit, if the engine is turned off immediately, the boiling coolant will stop circulating (for most engines, the water pump is driven by the crankshaft).

Although there are many types of vehicles, the structure is similar. This should be said to be the credit of standardization, but also the need for large-scale production lines. With the development of society, the progress of science and technology and the change of demand, the shape of railway vehicles has begun to change, especially the passenger car is no longer the same old face.

However, their basic structure has not changed significantly, but the specific parts have a more scientific and advanced structural design.

Generally speaking, the basic structure of the vehicle is composed of five parts: the car body, the undercarriage, the running part, the coupler buffer device and the braking device.

The car body is the part of the vehicle that is used to load goods or passengers, and is the basis for installing and connecting other components of the vehicle. The body of the early vehicles was mainly made of wood, supplemented by steel plates, bow rods, etc. In modern times, the car body is mainly steel structure or light metal structure.

01 refers to the slow response, like an old motorcycle; It can also refer to gossip, boredom, and rumor-mongering.

The ** of the locomotive is actually evolved from Taiwanese swear words, which means the same as Cantonese"The first loss was lost"It's very similar, but because it sounds like **, some people changed it to something more elegant"Locomotives" "Locomotives"It refers to the person's behavior and demeanor that makes people feel strongly unpleasant or unpleasant, but now it has become a meaningless mantra, sometimes it is not the meaning of swearing, it depends on the tone and attitude of the person at the time, that is, the person is indecisive, this is okay, that is okay, and then this is not good and that is not good.

Doing things procrastinate.

Locomotives were first popular in Taiwan, China, mainly referring to the meaning that there are many problems, many opinions, and very picky. Locomotives in Taiwan are not allowed to use the highway, so "locomotive" is extended to mean "not on the road".

In fact, "you are very locomotive", this sentence is not an Internet term, but a Taiwanese mantra, "locomotive" in Taiwanese refers to a person who is very picky, and there are many problems, and I have some opinions about this person. Add you very much, what this means is, why are you so troublesome, so picky, and have so many questions.

However, for many Taiwanese young people, this sentence has become a mantra for them, and sometimes they say "you are very locomotive", and it is not that they are dissatisfied with another person, it is likely that they are just joking.

Other mantras

1. Ann. If you encounter any small setbacks or bad luck and tell your friends, you will definitely respond to you with a "safe and la". Meaning no problem, don't worry.

2. Thanksgiving. Ouyang Feifei's song "Grateful Heart" is popular in the mainland. Under the impetus of several major Buddhist groups, having a grateful heart has become the simplest word of discourse.

When you congratulate someone, they will often say "thanksgiving", which means thank you and I will cherish it. "Gratitude" is pronounced in Taiwanese like "warmth".

Locomotive, written in writing, refers to the locomotive used to guide or push the operation of railway vehicles, and the locomotive itself does not carry goods, that is, the locomotive. At present, locomotives are the least energy-consuming land transportation vehicles in terms of fuel consumption per ton-kilometer of transportation, and in Taiwan, and even in the mainland, heavy motorcycles are called "locomotives".

What is the difference between a motorcycle and a motorcycle?

The maximum speed, weight, and output power of motorcycles belong to the range of motor vehicles, according to the displacement, they are divided into 50cc light locomotives, 50-250cc are small locomotives, 250-600cc are called medium-sized locomotives, and more than 600cc are called heavy locomotives.

So there is no essential difference between motorcycles and motorcycles in theory, but motorcycle enthusiasts like to call heavy motorcycles locomotives.

In terms of power, the acceleration of 100 kilometers below 250cc is basically more than 8 seconds, the acceleration of 250cc-400cc 100 kilometers is between 6-8 seconds, the acceleration of 400cc-600cc 100 kilometers is 4-6 seconds, and the good car above 600cc can basically be within 4 seconds, and the displacement of liter cars and above can basically settle in the 3 seconds or even 2 seconds club.

Heavy locomotives have been on par with luxury cars in all respects, and even surpassed them in some respects. Such as: navigation, tire pressure monitoring, trunk, battery level, lifting windshield, real-time fuel consumption and so on.

Moreover, there are various advanced catalytic equipment in the oil circuit, which meets various strict environmental protection standards, and the fuel injectors are basically upgraded to electric injection, which has long bid farewell to the carburetor era.

Meaning 1: Locomotive. A locomotive is a self-propelled vehicle that pulls or pushes a railway vehicle to run without carrying a business load, commonly known as a locomotive.

Meaning 2: Describe a person who has a lot of problems, is instigated, and does not go to the Tao. It was first popular in Taiwan, China, and the locomotives in Taiwan, China could not get on the highway, so "locomotive" was extended to mean "not on the road".

Meaning 3: Refers to the slow reaction of people. For example: This person is very locomotive, and he hasn't reacted after talking for a long time.

Meaning 4: refers to gossip and rumor-mongering. Generally, it refers to the non-objective reporting or writing of things by reporters or online writers.

Meaning 5: Heavy motorcycles. In Taiwan and other places, as well as in mainland China, heavy motorcycles are also called "locomotives", and "machine" is a paraphrase of motor.
