Understanding your car's engine control unit (ECU)

Understanding your car's engine control unit (ECU)

These days you are new cars equipped with the latest engine technology to find. The engine of the car is a huge change from the carburetor to the ancient right engine control unit (ECU) is submitted. In the 19 th Century, when the first single-cylinder gasoline engine driver of the vehicle entered into force, was the "carburetor" that has emerged. Later, several cylinders were considered to be a new thing. Finally, in the early '80s, we got a new car, consisting of control -Fuel supply, air and spark to the cylinders ICE. It 'was the injection system that was created to replace the old carburetor. In a multi-point fuel injection system, fuel is injected into the cylinders individually. The fuel injection according to the commands of '"on-board engine management" of the computer. This computer is known as the engine control unit or ECU.

The main occupation of the method is based engine control unit (ECU) is the controlthe different functions of an internal combustion engine. Previously, the ECU, which was installed in most cars and sets the parameters of the engine. In addition, the carburetor should determine the amount of fuel per cylinder / per engine cycle. Injected in other words, the simple version of the controller to control only the quantity of fuel into each cylinder is, for each engine cycle. The progressive nature of the engine control unit (ECU), which are installed on most modern cars are able toControl of ignition timing, variable value timing (VVT) and other peripheral devices.

The ECU (engine control unit) controls the engine through sensors, so that it can obtain information about the amount of car fuel, ignition timing and other parameters to be collected. The controller uses the input data received from sensors located in the engine. The various types of sensors that are mounted above the engine, MAP sensor, position sensor, throttle, airTemperature sensor, oxygen sensor and many others. The sensors are integrated into the engine, in principle, the purpose of determining the various "conditions of engine operation and performance. These sensors monitor the various aspects, such as ambient air temperature, engine / coolant temperature , exhaust / main fold-temperature, exhaust O2 content, throttle position, using the engine speed, vehicle speed and engine. The ECU (Engine Control Unit) control method,where you control the output of a system to control the inputs of a system. Since the ECU (engine control unit) collects data from various sensors, he knows all about the temperature of the coolant, the amount of oxygen in the exhaust gases. Based on these existing data, start the ECU (Engine Control Unit) implementing the massive computing per second. Based on the interpretation of all the programmed input data available, the ECU (engine control unit) to the desired positioncontrols used to throttle the engine and power, and thus to help achieve a satisfactory performance of the motor car.

Mile-High Lift kit for Nautical Star Tattoos - Understanding of the So-Cal Bro

Southern California is full of niche community of real estate tycoons Burnouts singing yoga tantra mantra yantra, and how-like. One of the most interesting of the southern California subspecies is the So-Cal Bro. By definition, a So-Cal Bro typically a young male in some part of the Bro-delta, the area between the three points of San Diego, Orange County and San Bernardino County. Often the trucks are emblazoned with the name of their team in a largewhite calligraphy on the rear window. The dress code consists of caps (right), sunglasses (branded and more valuable than the whole team), a white woman-bats undershirt (if a T-shirt to wear at all), large shorts Dickies brand (which are always standing up), the arms and chest with tattoos star unexplained, which have been more closely shaved, waxed or covered.

While inland from the coast bros bros differ in the choice of shoes and sunglasses (Coastalbros are easily identified by their flip-flops), they share a common language, one flavored with the words: "Dude" and "Bro!" In fact, it is not uncommon to hear a sentence like: ". Friend, brother, that guy was so sick" Translation: "Wow, that was great"

While the obsession with clothes, language and odd with a time of 04:20 makes it an easy target, it is hard to fault a guy who moves so much time on his journey. Additional respect you, because most of the work make do-it-yourself. And with the 'Simplicity of the modern updates, who can blame them?

You do not need saws, grinding or welding equipment to install and come with urethane or aluminum spacers that fit in your coil springs.

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. Exhausts poorly designed, that water will flow back and fill the waterlock / muffler box then the pipe into 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 away to be 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.
