How Can A Make A Fuel Pump On Astra

FOLLOWS THE MARINE ENGINE

order to exit and enter the port can not use the sails, because it would be a bit 'dangerous, for obvious reason that I am not here to enumerate. So we need the classic engine. This part may seem less interesting than those that follow. Certainly the engine fans already know everything and will be facilitated to understand and study this part.

The engine is used for sailing boats used in addition to the maneuvers of exit and entry into port, even as an auxiliary engine for any case during our navigation.

How are these engines? Marine engines are either endothermic, that is, internal combustion engines. There are four phases: intake, compression, combustion or expansion, exhaust.

motors can be divided in cycles of phases:

four times: the cycle is complete with two movements complete and return the four phases are separated from one another.

2 times: a complete movement and return, the phases overlap each other.

addition the engine can have two types of fuel.

Gasoline: Gasoline is the fuel used. During the intake stroke is fed into the combustion chamber, a mixture of air and fuel. The power stroke is caused by the spark of the candle.

Advantages:
- more power at the same weight and dimensions;
- absolute dependence on an electrical installation;
- refined fuel, and cleaner, not a problem of filter clogging.

Disadvantages:
- absolute dependence on an electrical installation;
- high combustibility
for the type of fuel - fuel that produces volatile highly flammable vapors.

Diesel: Diesel fuel types used. During the intake stroke only air is immense in the combustion chamber. The power stroke takes place by injecting fuel into the combustion chamber that ignites on contact with air and high temperature.

Advantages:
- higher yield;
- cheaper fuel;
- independently from an electrical system;
- low combustibility for the type of fuel;
- safer fuel does not produce volatile highly flammable vapors.

Disadvantages:
- less refined fuel, clogging filters.

addition to this major difference, the motor may differ by location and transmission. Inboard
: Engine and transmission inside the boat.
Outboard: Engine and transmission to the outside of the boat.
Enfrofuoribordo: Engine and transmission within and outside the boat.

addition, the engine must be cooled, if not get warm. They are used two ways: the direct and indirect.

Open = Direct . The pump of the fishing sea water and sends it directly to cool the engine parts concerned and is expelled from the tailpipe, the engine used less power.

Advantages:
- lighter;
- less mechanisms, and therefore more reliable.

Mixed = Indirect . The pump of the fishing sea water and sends it to cool water mild closed-circuit cooling. It is then expelled from the exhaust pipe cooling, in turn, is fresh water to cool parts of the world involved. The temperature is maintained at optimum levels by the thermostatic valve which excludes the heat exchanger when the temperature is still low, and alerts when the temperature is too high. Used engine more power.

Advantages:
- smaller scale in the cooled parts.
- best performance at the start and at lower temperatures.

The direct cooling system is most commonly used, although the technology and typology of the new engines are moving towards the realization of the indirect.

OUR MOTOR

As we all know the real engine of our boat are sailing the sails. There are essentially two types of boats: the mainsail and jib, but the vessel can be equipped with both spinnaker and spinnaker sails to a navigation expert.

on all sailboats will find the first two sails available. Explain how the sails should be adjusted on a blog is impossible, for obvious reasons: you must be at sea to learn how to adjust the sails, and there are no fixed rules. A very general rule is that the sails must fuck [Pull in: it is a nautical term that means to Tighten a sail through the appropriate sheet of the mainsail or jib, in this case. The sheets are the ropes that allow us to adjust the sails] when we close-hauled or large, or gaits that allow us to tighten the wind, and let [Leave: remove the tension on the sail, a sail to swell] when we move away wind, sideways, loose, loose large, and stern, especially gait. These rules apply to the sails as the mainsail and jib, but the spinnaker and the spinnaker, there are different settings.

upwind is to go with the bow of the boat (front boat) near the corner dead. The dead angle is an angle of about 90 ° that we spend just to change tack in our sails, and direction. If you accidentally end up in this corner, we are against the wind, our sails and begin to bring more fileggiare and not because the wind is no longer used as a laminar flow to drive the boat.

Other nautical terms to know:
starboard = Right;
Left = Left;
Bow = Front of the boat;
Poppa = bottom of the boat;
luff = upwind, approach corner dead
Place = Move away from the corner dead
= Change Tack Tack;
= remove wind into the sails furled, lower the sails;
= Hoist the sails to the wind, raise sails.

be sailors. You can not decide overnight to become sailors. You may decide you want to try to understand this world, but be sailors, is a way of life, of thought, a passion that comes from inside you, it's the adrenaline you can feel.

This blog does not presume to teach you to go sailing because you can only learn from experience and field, or cause to be a passion for this great sport, but wants to get closer to the sailing world, explaining some theoretical stuff.

Unfortunately, even if a person is the greatest skipper, or has a great passion is not enough to navigate through the sea alone, you need to have a sailing license, as a pilot who wants to drive down the street without a license can not go anywhere. The boat license is like a driver's license, if they are in possession does not mean that you know drive, it means that you feel responsible enough to drive down the street, even though we know that these criteria are not very efficient. In fact we have all learned to drive since we have a driver's license examination is to judge that the candidate is in the possession of the bases, to be independent in the guide. The same applies for the license. The examination is used to judge whether a person is eligible for potertesela get enough out at sea, and let's face it all, stay out at sea, is different than driving on the road. By car you have to be attentive to other drivers, which is not much, but, at sea, you have to do with more forces, such as weather conditions, and especially with the sea, which is the major cause of damage.

Warning: do not damage them because ever since the boat does not have the ability but, man, that is wrong in something that could be a ploy or not the failure to properly set the sails, or checking the condition of the boat which must be in good condition and you can surf safely, and then lead a pleasant visit.

From here on I will start to publish articles that will explain in simple terms the arguments you need to know when considering coseguire to the license. Obviously, these items do not replace the "guide to pleasure boating," but I hope it will help you understand the concepts more important. At the same time, for all the visitors of this blog vels that are not or are not fans of sailing, can begin to have an interest in the sport, lifestyle, a passion that is called: SAIL.
