Why do buses have rear engines?
When loaded, buses get traction thanks to being rear wheel drive.
This will ensure that the back wheels and engine are connected.
Power loss and an increase in weight are the result of having to put in a transmission shaft.
A rear engine prevents this and is better overall for the bus.
Weight distribution. It prevents damage to roadways.
Sometimes 3 digit numbers are used for express buses and 2 digit numbers are used for local buses.Sometimes the even/odd status of the buses can indicate whether the route goes north or south (this works much better for grid cities where single direction routes make sense).
trucks have broad wheel because so that it reduces pressure and the tyres dont burst.
Though old buses are not equipped with turbocharger the buses manufactured nowadays are fitted with a turbocharger.Yes, they can be used.Matter of fact, turbos have widely been used on diesel engines for a while now.Bus engine revs at low rpm .and in case of turbo charger it needs higer rpm to ge...
School districts are allowed to install and operate automated school bus safety cameras to detect violations of drivers that overtake and pass stopped school buses.Requires every school bus be equipped with an external video system and authorizes the use of an internal video system.
“Jake Brake,” a registered trademark of Jacobs Vehicle Systems, Inc.(Jacobs), commonly refers to a brake retarder, which is a supplemental brake used on trucks and buses that assists in slowing down the vehicle.While in use, a brake retarder makes a distinctive staccato sound, which can be quite ...
spoilers are the curved surfaces on the back of sports cars. they are designed in such a way that the flow of air past th spoilers at high speed exerts a high pressure on the car downward which helps the cars to give them the stability during their high speed races
Some school buses do have seat belts throughout the entire bus. For the most part, buses do not have seat belts. They tend to have seat belts in the rows closest to the front end. It depends on the town, village, city, that owns the buses. Some places make them regulation to have entire buses ful...
Here's the section of the Seattle Municipal Code pertaining to yielding to buses: SMC 11.58.275 Right-of-way of transit vehicles.A.The driver of a vehicle shall yield the right-of-way to a transit vehicle traveling in the same direction that has signaled and is re-entering the traffic flow.
Every time the stop-arm extends, a video excerpt is sent to our processing center.BusPatrol buses can store over 7 full days of footage inside and outside the bus.The school bus camera provides safety surveillance for kids inside the bus.School bus cameras also discourage poor driving behavior ar...
The short wheel base helps the driver maneuver the bus on city streets.
The law requires drivers to yield to transit buses that have signaled their intention to enter the traffic flow.If a bus is pulled off the roadway to pick up passengers you can legally pass the bus until it turns on its signal.Note that this law is specific to transit buses.
New law putting cameras on school buses goes into effect in Pa.A new state law that allows school buses to have cameras for recording drivers who illegally pass at bus stops went into effect this month.They also lose their license for 60 days and get five points against their driving record.
Maths explains why three buses always come along at once.Bus bunching occurs because bus routes are inherently unstable.When the buses are on schedule, everything seems to work fine.They travel from stop to stop, waiting at each for passengers to exit or climb aboard.
Many models of buses can be lowered into a “kneeling” position when they are stopped, which makes it much easier for passengers, especially the elderly and others with mobility challenges, to step up into or down from the bus.Why do buses stop before the bus stop shelter in most stops in London?
The hissing sound is because instead of fluid like a car would use, the truck uses compressed air to actuate the brake pads.They use very large diaphrams because the pressures are lower.When the truck is hooked up a trailer or should it be disconnected all that comes out of the hose is air.
6 Answers.Drum brakes are cheaper to manufacture than disc brakes, because there are fewer moving parts and because in the rear the parking brake (which often works by a drum-and-shoe mechanism even on four-wheel-disc-equipped cars) can share a drum with the "regular" brakes.
Note how even a short delay causes the buses to bunch together after a while.Bus bunching happens because, if a bus gets delayed, then there will be more people waiting at the next stop than anticipated.The extra passengers' boarding time makes the bus even later, and so on in a vicious cycle.
No, there were no motor vehicles at that time. There were horse-drawn trolleys running on rail tracks. After Edison developed the use of electric power about 1888, electric trolleys ran on the same rail tracks. In the 1930s General Motors promoted the use of motor buses powered by diesel engines ...
Enterprise does indeed offer bus rentals if you need one for travel. They have many different varieties and you can select the one that is right for you based on size and price, one option is a seven seat bus that you can find more info on from http://www.enterprise.com/car_rental/deeplinkmap.do?...
Firing order in an engine is important because a correct firing order can cause minimum vibrations in the system.Hence most popular engines implement even number of cylinders with a particular firing order so that the system is fully balanced and no vibration is produced in the engine.
Why Diesel Engines Produce Higher Torque than Gas Engines.Cars with diesel engines generally struggle to compete with their gasoline-powered counterparts, which have higher horsepower and accelerate faster.Combustion: A gas engine compresses a fuel-air mixture and then ignites it with a spark.
At cruise altitude, more thrust means a higher cruise altitude is possible, which makes for better fuel efficiency.So while a 4-engine aircraft can certainly fly on 3 engines, and in many cases (depending on weight and outside air temperature) on 2, it can't fly as high as it could with all 4.
Auto Repair For Dummies, 2nd Edition Wheel bearings usually come in pairs of inner and outer bearings.Usually, only the non-drive wheels (that is, the front wheels on rear-wheel drive vehicles and the rear wheels on front-wheel drive vehicles) have repackable wheel bearings.
They have a high center of gravity because of their height. They mainly tip over because of wind or a sharp turn.
They generally accelerate slower than the cars that surround them.So a bus travelling at the same speed as cars has to start slowing down sooner than cars, shortening the distance covered while at the same speed as surrounding traffic.The stops take time to let passengers on and off.
engines in buses and coaches are placed underneath at rear or side to facillitate the flat floor inside this allows less noise, more inside room, and luggage compartments under passenger compartment
The first streetcars started popping up in various American cities around the year 1881.One of the most influential American inventions of the time, these buses on rails were able to hold more passengers than ever at a low cost, enticing more pedestrians to hop on for a ride around the city.
Shuttle buses are any type of bus service intended primarily to shuttle passengers between two fixed points.These can be bus or coach operated, but are usually short or medium distance journeys taking less than an hour.Shuttle buses will usually link with other transport hubs, such as airport shu...
Buses are usually much cheaper.Public transport is often much cheaper than using the car, especially for short city journeys.This kind of journey works out more costly on a per mile or km basis, as cars burn more fuel in the early part of a trip.The bus definitely wins on cost!
There are several reasons, the main one relates to the weight transfer that occurs when applying the brakes, making the front wheel brakes work harder, thus needing more effective stopping power and more efficient cooling.It is basically a matter of cost. Drum brakes are cheaper to produce than d...
Hatchbacks and estate/station wagons have a lip of metal between the top of the rear windscreen and the roofline, leaving room to install a windscreen wiper. The wiper mechanism can also be mounted below the windscreen reaching upwards, saloon/sedan cars have no room in either of those places.The...
By moving more people with fewer vehicles, public transportation can reduce greenhouse gas emissions.Heavy rail transit such as subways and metros produce on average 76% lower greenhouse gas emissions per passenger mile than an average single-occupancy vehicle (SOV).
The choke 'chokes' air going into the engine through the carburetor, effectively increasing the amount of fuel in the cylinder.In cold weather, this increases the chances of ignition.Once the engine warms up, normal air-fuel mixture is restored by pushing back the choke lever.
The reason that most cars have the engine located here is because they're front-wheel drive (FWD), and placing the engine directly on top of the wheels maximizes traction under normal driving conditions.From behind the wheel, a front-engine car is the easiest to drive.
Typically, MR cars are designed for optimal balance and handling.They provide better stability during hard cornering, which in turn provides better performance.This is due to their near 50/50 weight distribution.RR cars, (rear engined, rear wheel drive) are great cars for all-round weather condit...
So, while federal law or its customer contract may not require a voucher or partial refund for a delayed bus, you might be able to persuade a company such as Greyhound to offer compensation.That's what Jacquie Cadorette does whenever her bus from New York to Philadelphia is delayed.
1998 GM Saturn (all models) have rear brake shoes
Acrylic number plates sigify the registration mark of a vehicle. Currently the UK regulations insist on a yellow rear plate unless the vehicle is a classic car and can display black and silver plates.They can be made of different materials, but more commonly seen are metals and acrylics. http://w...
FWD cars dont have a rear axle, the wheels are mounted independently, there may be some situations where there is a tube there, but it will not have an axle shaft.The wheels just ride independently on bearings, they aren't connected by an axle like in a RWD vehicle.
Bus fare is $2.Metro transit buses have been outfitted with new fare boxes that verify and count bills and coins, like vending machines, and allow officials to more closely track the transactions.Now, these modernized boxes no longer accept pennies, half-dollar coins or $2 bills.
Modern diesel cars produce 10 times more toxic air pollution than heavy trucks and buses, new European data has revealed.However, the buses and trucks have larger engines and burn more diesel per kilometre, meaning that cars produce 10 times more NOx per litre of fuel.
To let the fuel and air into the cylinder and to let the exhaust out. Inside a motor there is a space (cylinder) where fuel and air is compressed by a piston then ignighted by a sparkplug. A valve is a little round disk with a stem coming out of its middle. The valve moves into that space creatin...
Greyhound starts bus service in Mexico, with connecting routes to Texas.Greyhound, an American brand more than a century old, began bus service in Mexico on July 15.For the first time, Greyhound has begun bus service within Mexico.Promotional fares start at $1 a ticket or 25 pesos, a Greyhound st...
Why do school buses have the flashing white lights on top? It's a strobe light that flickers fast.The buses that I've drive had a LED strobe light install because we had a fog every morning.It helps the bus to stay visible during transportation.
The simple answer is that they don't need them.In a cost/benefit analysis, the cost of adding seat belts to school buses outweighs any potential benefits, according to NHTSA studies.Modern school buses are large and heavy, and their passengers sit high off the ground.School buses are designed to ...
Rear drum brakes can lock for several reasons.One reason could be a defective wheel cylinder, which is part of the brake system.It is found on top of the shoes, and its function is to place force on the shoe so it comes into contact with the drum.A defective cylinder can cause brake lock up.
well front engine is cheaper gas due to it in front pulling vec. and rear eng. is in back pushing vec.
The 4.6L V8 engines that ford introduced into the Mustang in 1997 are of an overhead cam design, which is totally different from the pushrod V8.However, later versions (and many other cars today) now feature dual overhead camshafts (DOHC), which places 2 camshafts per cylinder head.
In a car engine, gasoline is burned inside the engine, which ignites the fuel and releases energy that moves the car.There are also other methods of internal combustion, such as diesel engines and gas turbine engines.Internal combustion is an efficient system that requires a relatively small engi...
