Understanding Exhaust And Your Motorcycle

Understanding Exhaust And Your Motorcycle

Exhaust System

When you get the motorcycle of your dreams, you may think that that's it and you are going to be done with it. That's not always the case. Knowing what you can do for you is just the beginning.

People often times take for granted the role that exhaust plays in their motorcycle parts needs. They may not understand that when your bike has a bad exhaust on it, you will not be able to drive it far. This is not a great thing to have to worry about when you just bought your bike.

There are many places that you can get your exhaust system. These include your local motorcycle parts store as well as other stores in the area. You may be able to get a good discount on your exhaust when you are looking on the Internet or at the places that may sell them for cars.

The other option is to do put it together yourself. You will need to have some kind of experience with motorcycle parts so that you know where it goes of all things. You also want to make sure that you are ready for that kind of work. It really takes a lot of work to put it together and make it work for your bike.

Your bike is going to need a certain kind of pipe to make it work for you and what you are doing. This can mean letting a professional find the motorcycle parts that you are looking for and putting them on your bike in the end. People think that it's easy to do, but it really does take some work to get an exhaust system on your bike. Take the time to figure it out and get it right.

When you decide that you are going to put a new kind of exhaust on your bike, you may not worry about what kind of pipes you want to use and what it will sound like. You really need to pay attention to what you are doing with your bike and how it sounds. A bad job can hurt the way that your bike functions and the way that it sounds too. Take the time to find the right motorcycle part for your bike and your needs so that you are happy with the outcome and the sound of your bike for the life of it.

Understanding Fuel System Subaru WRX

Understanding Fuel System Subaru WRX

Exhaust System

One of the keys to achieving the right balance of power is the fuel for a certain amount of air. Showing too much or too little fuel in an engine, which delivers the power, the poor economy and a big question mark against his long life. The main task of the engine tuner to ensure that the engine management system has been programmed to deliver fuel in the right quantity at any time.

Fuel mixture is measured in units of either oxygen or fuel-air(AFR). Also referred to as either lean (small amount of jet fuel) or rich to mention regular (large quantities of jet fuel). What is the right mixture of fuel and air? Although there is no such thing as an absolute all areas of recruitment, the generally accepted "golden rules" of the fuel mixtures:

1 At low power outputs (no increase)-catalyst-equipped vehicles, a fuel mixture of lambda need 0.99 (14.64 AFR) for the best mix of fuel and emissions control is the goal when the OE is working inClosed-Loop. Improvements in fuel savings alone can out of fuel mixtures are made to Lambda 1.05 (AFR 15.4 to 1), but this is done at the expense of the cat converter and exhaust gas temperatures will increase in cruise.

2 medium-power outputs (the transition between on and off boost) provides the best performance at around lambda 0.89 (AFR 13.1 to 1) is reached.

3 The power of high performance, it is interesting because this is the area where the greatest potential for engine damage.Version that I have for the stock motors with internal running about 1.2 bar of boost pressure is usually a good reliable service to Lambda 0.78 (AFR 11.5 to 1) VI. At the same boost pressure, and internal stock Subaru WRX Version VII and new models have the cylinder head combustion chambers of a completely different combustion properties and distribution of fuel than the previous model, revised and dictated a lot of fuel mixtures richer around lambda 0.75 (AFR 11, 0 to 1) or lower is best accomplishedMakes it safe.

Typically, air-fuel ratio to be slightly edited for a small increase in power for motors with forged pistons, which is diminished due to their greater strength and heat resistance than OE cast pistons.

Measure fuel mixtures

There are only two ways to fuel mixtures to examine closely the preferred method is to use a broadband high-quality air-fuel ratio meters with five-wire Bosch LSU Lambda. This type of sensor andInstrument can accurately measure fuel mixtures of lambda 0.69 (AFR 10.1 to 1) to 1.30 Lambda (AFR 19.1 to 1) and beyond. Hence the name of the sensor to broadband.

An alternative method for vehicles with compatible flash control unit, fuel mixtures can be read directly from the data stream ECU with Delta Dash, with few exceptions. The OE-oxygen sensor can "see" lean, but can not measure fuel mixtures richer in oxygen 0.76 (AFR 11.2). In addition, a higher rate of storage, sensorPositioning is a problem, as the pressure between the engine and exhaust turbocharger causes a marked reduction in the precision of the sensor.

Any other method of measuring fuel blends as a good DIY meters, reading tea leaves or consulting a psychic have no place in modern high-performance engine tuning.

Understanding A Marine Exhaust System

Marine exhaust systems are an important and often neglected engine of a ship. Most ships have a system of "wet" exhaust. The outlet for the exhaust gases from the exhaust manifold - the salt water is injected into the column. This mixture of gas and water is then passed through a series of curves to it from the boat, preferably in the back.

Exhaust fumes mixed with salt water to create a highly corrosive compound. This is why exhaust systems are often non-corrosiveComponents such as nitrile rubber reinforced hose (brown - not green - stripe), galvanized steel, fiberglass or plastic. The purpose of these components, which vary in size and shape depending on the size of the engine and the layout of the engine room is to prevent the engine hydraulicing. This occurs when an engine full of salt water that entered through the exhaust and can cause considerable damage if left for more than two hours. The water enters the exhaust gas to swell in the tail and armDrain design. In some sea conditions, such as by sea, the water can again be forced to exhaust when the engine is not running. Drains poorly designed, that water will flow back and fill the waterlock / muffler box then the hose in the exhaust manifold, exhaust valves and combustion chamber. With the engine full of water can not compress the engine crank over, it is not like water.

Exhaust System

You will know that your engine is if you do not turn around hydrauliced ​​-usually after a long period of sailing - and removing the starter and make sure it works. To remove remove water from inside the combustion chambers, first of all injectors, crank engine blowing over the water, replace vent injectors, injector lines and restart. Then leave the motor running until exhaust fixed.

Check that the mast is not coke up or corroded - a common problem. To check the exhaust riser remove the drain hose from the riser (often a difficult procedure)and look at the line, to see if it is the accumulation of exhaust / salt restricted. When building the riser is too large to be removed in order to check the engine side of the line. Coke can be scraped off as a short term fix although often the riser must be replaced. There are aftermarket systems which vary in quality. Make sure you fit the right model for your application.

Make sure that the water-lock is low enough and large enough to hold all the water in the exhaust system. There is aA gooseneck or central vertical loop in the vent pipe to rely on the mirror? It is a siphon break and function - without valves leak?

Exhaust is toxic and can cause motion sickness and headaches. Replace defective components immediately. Use double hose clamps on each joint or, preferably, super, the style of concrete drain bolt, if necessary. Hot sections should be insulated with fiberglass tape to prevent burns.

Asbestos Warning delayed. Many larger vessels andMarine engine installations had exhaust systems that were lagged with asbestos tape and rope. Asbestos was common in older boats noise.
