Is the engine of a large bus in Beijing in the front or in the rear

The engine of long-distance buses and buses is usually located at the rear of the vehicle. Some buses produced in the 1980s and 1990s also had engines located under the cab, such as the Dandong-Huanghai bus.

The position of the car is also different according to the model. In the past, most of the old-fashioned engines were directly in front of the vehicle, on the right side of the driver's position; now most of them are natural gas dye engines, mostly at the rear of the vehicle.

The rear engine of the bus is conducive to heat dissipation and maintenance, because the engine is at the tail, and the silence is also significantly improved.

What is the bus made of

1. Electric buses refer to buses powered by on-board power supply, and electric buses are equipped with suitable on-board batteries or cable power supply equipment to provide electricity-driven. Electric buses mainly refer to pure electric buses, [1] all of which are driven by electricity.

2. Three parts. According to the official website of Yutong pure electric bus, the electric vehicle power system mainly consists of three parts: power source, power electronic system and motor drive system.

3. Definition: Buses, city buses, that is, buses or buses, are typical models of medium-sized and medium-sized buses. They are commercial vehicles specially designed and equipped to solve urban and suburban transportation.

4. The basic structure of the car is mainly composed of several systems, including engine, chassis, body and electrical equipment. No matter what kind of car, the basic structure is the same, but the materials and electronic equipment are different. The basic structure of the vehicle includes the following four parts: car engine: engine is the power device of the car.

What is the displacement of the bus?

15 bus seats, 66 kilowatts, displacement is about 3 liters, and about 20 seats, power 100kw, displacement 5-5 25 seats (relative), power 130, displacement may be 6 high-end cars with a displacement of more than 40 seats can reach 15L. Low-end, 180 horsepower, displacement 8~9L.

liter. Buses, urban buses, that is, buses or buses, are typical models of medium-sized and medium-sized buses. They are commercial vehicles specially designed and equipped for urban and suburban transportation.

Category: Transportation/Tourism Other means of transportation Analysis: Take the 10-meter-long bus, which is common in big cities, as an example. Generally, it is a 6-liter displacement diesel engine, and an 8-meter-long bus has a 5-liter displacement.

Generally, large vehicles such as urban buses, tour buses and trucks are not marked by displacement, but by power.

Generally speaking, the displacement of most active internal combustion engine buses in Beijing is between 6-9L, and most of them are in-line six-cylinder layouts. The engine brands are Yuchai, Fiat, Cummins and Iveco, and the gearboxes are mainly Allison and ZF.

The medium-sized 6000-7000CC and the large 9000-10000CC engine are similar, but much bigger.

What is the engine of the bus

1. There are many types of engines used by buses now, mainly diesel engines, gas fuel (CNG), liquid fuel (LNG), electric and hybrid power;As for the displacement, it depends on how many meters the bus is. The longer the car, the greater the horsepower of the matching machine, the corresponding displacement will gradually increase.

2. Buses are large buses. Buses are an important means of transportation for people to travel. Most cities have buses. Most buses have rear engines, and most buses also use diesel engines. Almost all buses are rear-wheel drive.

3. The reason why buses and trucks use diesel engines is that the diesel engine has a large torque. And the ignition methods of diesel engines and gasoline engines are also different. The gasoline engine has spark plugs. After the compression process, the gasoline engine spark plugs will release sparks to ignite the combustible mixture. Under the combustion of mixed air pressure, the piston, the engine can output power.

4. Buses below the meter generally use four-cylinder YC4110Z, YN4102, CA4113 series. 9-meter buses are mostly gasoline vehicles, and 6-cylinder EQ6100 and CA6102 are common. 10-meter to 12-meter buses generally use 6-cylinder turbocharged diesel engines.

5. The old-fashioned Guangzhou and Huanghai, and even some cities use Fulai Xisai (such as some lines in Wenzhou, such as Route 38) use gasoline engines.

The body of a traditional bus is so large and has so much carrying capacity. Is its engine bigger than that of ordinary cars?

The diesel engine of the bus is large. If it is installed in the front, the engine will stick out for a long time, which will take up a lot of space.And space is what buses need most. It needs more people. The gasoline engine of the car is relatively small enough to be placed in the front.

The overall body strength is not strong, so it is rarely used for professional SUVs. The load-bearing body is mainly used for off-road vehicles, and the shape is relatively tough. Moreover, because the independent chassis can use differential locks, four-wheel drive equipment, etc., the overall toughness of the body is relatively high, but the comfort is not very good.

Comfort is different. Non-load-bearing bodies have a long history, but they also face the disadvantages of not being suitable for the times. For manufacturers, non-load-bearing bodies are also not conducive to automotive engineering design.

The second reason is that buses are generally rear-wheel drive. If the front engine is designed, there will be a high loss of power transmission. Unlike family cars that can be set to front-wheel drive, the full-load mass of buses is generally relatively large, so the demand for power is greater.

Where is the engine position of the bus?

1. The rear of the car. There are generally warning reminders of "rear engine" in the car.

2. Now it is basically this design, which reduces the noise and temperature in the car, saves passenger space, and can also complete maintenance outside the car, which is suitable for the needs of public transportation such as buses.

3. According to the development of your city and the length of the bus in the city, the position of the engine is determined. [Nowadays, urban buses are basically rear engines. Some fuel tanks are on the left, some are on the right, and most of them are on the right.], the basic position of the fuel tank is generally in the front wheel. Behind, about 1-2 meters.

4. Car engine installation position - The rear engine of the engine often corresponds to some high-power rear-wheel drive vehicles, typically including city buses, highway buses and high-end sports cars. In addition, there is another layout, that is, the engine is located between the front and rear axles of the car.

5. The engines of long-distance buses and buses are usually located at the rear of the vehicle. Some buses produced in the 1980s and 1990s also had engines located under the cab, such as the Dandong-Huanghai bus.

6. The engine is at the front of the vehicle. This is the most common way of engine placement. When the engine is driven by the front axle, the engine can be placed horizontally or vertically, or placed outside the wheelbase, within the wheelbase or above the front axle.
