Under The Hood

[vmail]

Hi, on the air filter box there is an air intake duct and another duct with a maf sensor going to the engine

There is also a smaller pipe but I'm not sure what it is

Is it an idle-up valve? and is it safe to block it up?

I also need 12v 0.4W from under the hood, and it has to to be easy to access, but the circuit should only be activated when the ignition is on or when the engine is running

Breather system?

Breather system?

What are those breathers? What do they do? And can I get some?

You just have to dive in to a post and submerge yourself in the topic :P

[KPARRIS-JONES]

Exellent feedback.

Won't the engine heat blow up the oxygen tanks though?

:P

bizarra and ricey keep it in your thread boys, and jonesy it just lets more air go somewhere to do summat to improve stuff, hth

I will save him the trouble:

A nuclear reactor is a device in which nuclear chain reactions are initiated, controlled, and sustained at a steady rate, as opposed to a nuclear bomb, in which the chain reaction occurs in a fraction of a second and is uncontrolled causing an explosion.

The most significant use of nuclear reactors is as an energy source for the generation of electrical power and for the power in some ships. This is usually accomplished by methods that involve using heat from the nuclear reaction to power steam turbines.

The physics of operating a nuclear reactor are explained in Nuclear reactor physics.

Just as many conventional thermal power stations generate electricity by harnessing the thermal energy released from burning fossil fuels, nuclear power plants convert the thermal energy released from nuclear fission.

Reactor

The reactor is used to convert nuclear (inaccurately also known as 'atomic') energy into heat. While a reactor could be one in which heat is produced by fusion or radioactive decay, this description focuses on the basic principles of the fission reactor.

Fission

When a relatively large fissile atomic nucleus (usually uranium-235, plutonium-239 or plutonium-241) absorbs a neutron it is likely to undergo nuclear fission. The original heavy nucleus splits into two or more lighter nuclei, releasing kinetic energy, gamma radiation and free neutrons; collectively known as fission products. A portion of these neutrons may later be absorbed by other fissile atoms and trigger further fission events, which release more neutrons, and so on.

The nuclear chain reaction can be controlled by using neutron poisons and neutron moderators to change the portion of neutrons that will go on to cause more fissions. In nuclear engineering, a neutron moderator is a medium which reduces the velocity of fast neutrons, thereby turning them into thermal neutrons capable of sustaining a nuclear chain reaction involving uranium-235.

Commonly used moderators include regular (light) water (75% of the world's reactors), solid graphite (20% of reactors) and heavy water (5% of reactors). Beryllium has also been used in some experimental types, and hydrocarbons have been suggested as another possibility. Increasing or decreasing the rate of fission will also increase or decrease the energy output of the reactor.

Heat Generation

The reactor core generates heat in a number of ways:

The kinetic energy of fission products is converted to thermal energy when these nuclei collide with nearby atoms.

Some of the gamma rays produced during fission are absorbed by the reactor in the form of heat.

Heat produced by the radioactive decay of fission products and materials that have been activated by neutron absorption. This decay heat source will remain for some time even after the reactor is shutdown.

The heat power generated by the nuclear reaction is 1,000,000 times that of the equal mass of coal.

Cooling

A cooling source - often water but sometimes a liquid metal - is circulated past the reactor core to absorb the heat that it generates. The heat is carried away from the reactor and is then used to generate steam. Most reactor systems employ a cooling system that is physically separate from the water that will be boiled to produce pressurized steam for the turbines, like the pressurized water reactor. But in some reactors the water for the steam turbines is boiled directly by the reactor core, for example the boiling water reactor.

Reactivity control

The power output of the reactor is controlled by controlling how many neutrons are able to create more fissions.

Control rods that are made of a nuclear poison are used to absorb neutrons. Absorbing more neutrons in a control rod means that there are fewer neutrons available to cause fission, so pushing the control rod deeper into the reactor will reduce its power output, and extracting the control rod will increase it.

In some reactors, the coolant also acts as a neutron moderator. A moderator increases the power of the reactor by causing the fast neutrons that are released from fission to lose energy and become thermal neutrons. Thermal neutrons are more likely than fast neutrons to cause fission, so more neutron moderation means more power output from the reactors. If the coolant is a moderator, then temperature changes can affect the density of the coolant/moderator and therefore change power output. A higher temperature coolant would be less dense, and therefore a less effective moderator.

In other reactors the coolant acts as a poison by absorbing neutrons in the same way that the control rods do. In these reactors power output can be increased by heating the coolant, which makes it a less dense poison. Nuclear reactors generally have automatic and manual systems to insert large amounts of poison (boron) into the reactor to shut the fission reaction down if unsafe conditions are detected.

Electrical power generation

The energy released in the fission process generates heat, some of which can be converted into usable energy. A common method of harnessing this thermal energy is to use it to boil water to produce pressurized steam which will then drive a steam turbine that generates electricity.

Good explaination!

This is the sort of thing that seriously tempts me to go for A-Level Physics and/or Chemistry.

We've only just got into the molecular and atomic structures and stuff, and It's bloody good.

Does anyone here know what LASER stands for though? I have known this for quite a while, and a few others that I have met know too. NO CHEATING with google or wikipedia or summing!

I learnt it at 2:30 in the morning last year at the arport. No idea why I asked, but now I'm glad I did. Somehting interesting to know I guess.

I want to hear his description of a Nuclear Reactor...... :P

Some superheated fuel rods go into some holes and then boil some sort of liquid that produces a gas which is captured and spins a spinny thing which produces leccy using possibly copper wire and magnets then it goes into optimus prime (a transformer) and gets uprated and fed into the national grid
