CRANK SHAFT SENSORS

A crank sensor is an electronic device used in an internal combustion engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.
                    A crankshaft sensor monitors the rotational speed of your crankshaft and sends this information into your car’s on-board computer. The on-board computer will then adjust fuel delivery and spark timing according to the information coming from the crankshaft sensor. This makes it an important part of your engine system; a bad crankshaft sensor affects not only the engine speed but also the fuel efficiency of your car.
       Aside from controlling the fuel injection process and ignition timing, crankshaft sensors are also responsible for your car’s emission performance, power output, reliability, and driver-ability.
A crankshaft sensor is composed of two parts—the rotating part and the static part. The rotating part is a toothed disc or wheel that rotates with the engine cam. The static part is the crankshaft sensor itself. There is also a crankshaft sensor equipped with LED lights and gets its reading as the LED light pass through the slots of a disc that is attached to a wheel.



SIGNS YOUR CRANK SHAFT IS GONE BAD

1. Acceleration Problem
2. Engine Sputter
3. Increased Fuel Consumption
4. Engine Stall 

Acceleration Problems

A crankshaft sensor is responsible for monitoring the rotation of the crankshaft. If the sensor is awry it will send the wrong information into your car’s on-board computer, resulting in the inability of your engine operating system to sync the engine pistons together. This causes poor acceleration and makes your car fail to maintain constant speed.

Engine Sputter

Since the information relayed by the crankshaft sensor into your car’s on-board computer is used to determine the proper spark timing, a bad crankshaft sensor will relay wrong readings into the computer, affecting the fuel injection process and causing your car engine to sputter

Increased Fuel Consumption

Incorrect crankshaft sensor readings leading to spark timing and fuel injection errors does not only cause engine sputter but will also affect the fuel efficiency of your car. Have your car checked for crankshaft sensor problems if it takes you four gallons of gasoline to get from your home to the office instead of the usual two.


Engine Stall

If your engine stalls at low speeds and you have difficulty in starting your car engine then your car is most likely having crankshaft sensor problems. This is because the crankshaft sensor is responsible for ignition timing.


It is important to have your car checked by a professional auto mechanic when you experience symptoms like engine sputtering, increased fuel consumption, engine stall, and difficulty in acceleration. With a bad crankshaft sensor, your car engine cannot function efficiently and will eventually fail completely. A failing engine is not only costly to repair but dangerous, so it is in your best interest to recognize these symptoms quickly to get the problem repaired.

EVAPORATIVE EMISSION CONTROL SYSTEM (EVAP SYSTEM) IN CARS

Hello auto owners, it interesting to be with us for another auto-informative Thursday. Its great cos we are winding down to the weekend, and a lot of auto repairs jobs will be going down over the weekend too. So i would love to draw you attention to what i discovered,and what lot of car owners, mechanics, ignore possible because they know or don't understand it.

THE LOCATION OF THE EVAP SYSTEM IS FOUND UNDER THE FUEL TANK

We are going to be talking about the EVAP (evapourative emission control system). Lets get down to the basic to understand the concept of emission control.

                                              

                                              Controlling Emissions

The fuel we put in our cars contains more than 150 chemicals, including benzene, toluene and sometimes even lead. These ingredients can cause dizziness, breathing problems and headaches when they're inhaled. Inhaling large amounts of gasoline fumes can even cause death. On top of all that, evaporated gasoline is one of the leading causes of smog and air pollution.

For these reasons, car makers are required to install systems on their vehicles that HA typical system consists of a small canister full of charcoal, valves, hoses, vents in the fuel lines and a sealed fuel tank cap. When fuel evaporates inside the gas tank, the excess vapors are transferred to the charcoal canister. They're stored there until they can safely be transferred back to the engine to be burned with the normal air-fuel mixture.

When that's ready to happen, a valve creates a vacuum that draws the vapors into the engine. Fresh air is also drawn in through the vents and valves to mix with the vapors for better combustion. These systems can be controlled mechanically, or like on most on newer cars, through the engine's computer. The computer tells the valves when to purge the canister of vapors. This typically happens when the car is in motion, rather than at idle. It's just one example of some of the behind-the-scenes technology that you'll likely never see or feel.

As you may expect, things can go wrong with the EVAP system, too. If the canister fails to purge or does so under the wrong conditions, it can hamper the performance and emissions of your vehicle. When this happens, you may find that the entire system needs to be replaced.

Up next, we'll learn more about gasoline evaporation and discuss what you can do to reduce it in your own vehicle mitigate gasoline evaporation. Environmental regulation in the United States began in earnest in the early 1970s, and as a result, cars have had evaporative emission control (EVAP) systems ever since. These systems are designed to store and dispose of fuel vapors before they can escape into the atmosphere.

 SIGNS OF A FAULTY EVAP SYSTEM

Check Engine Light

A defective canister purge solenoid may also set off a Check Engine Light. If the computer detects any problem with the purge solenoid circuit or signal, it will set off the Check Engine Light to alert the driver that a problem has occurred. A Check Engine Light can also be caused by a wide variety of other problems, so it is recommended to have the vehicle scanned for trouble codes to be sure.

The canister purge solenoid is an emissions component and is therefore an important piece in making sure that the vehicle meets emission requirements. For this reason, if you suspect that your canister purge solenoid may be having a problem, have the vehicle diagnosed by a professional technician, such as one from Your Mechanic, to determine if the canister purge solenoid or vacuum hose needs to be replaced.

UNDERSTAND THE DIFFERENT LIGHTS THAT POP UP ON YOUR CARS DASH BOARD (CLUSTER SIGNS)

All of us love caring for our cars by providing them a thorough wash on each weekend, taking them for a routine service, installing various add-ons and of course, enjoying driving miles and miles of distance. But frankly - how many of us actually care to read their complete user manual as soon as the car is bought home? Perhaps only a few, and that too only when the real need arises during an emergency breakdown. In fact, one of the most important things that a daily driver must know about their car is to correctly interpret the dashboard warning icons. So, what are the dashboard warning icons? 
               These are small symbols which are normally located on instrument cluster, along with speedometer (behind the steering wheel), that indicate and provide an overview about the basic health of your car. Also, over the last few years, these indicators have gradually replaced the fashion of old-style analogue meters and because they tell about some of the most significant aspects, knowing them is necessary. Most of the warning icons in regular cars are almost self-explanatory – so let’s kick-start with the basic ones first.


(1) High-beams on:
Cause: As simple as its name suggests. The blue semi-circle icon with horizontal straight lines on its left indicates that your vehicle’s headlamps are turned on at the high-beam mode which ethically should not be, if you are driving on city with already sufficient lighting on the road for the sake to prevent glare on the eyes of driver in front.
Safe to Drive? Yes.
(2) Fog-lamps on:
Cause: This icon appears almost same as the high-beam but with vertical mark passing through horizontal lines and illuminates with yellow colour. It glows as soon as the fog lamps are switched on.
Safe to Drive? Yes.

(3) Engine Oil Level:
Cause: The oil level symbol is extremely important and should never be ignored because it tells about your car’s engine oil state. Please turn off your car immediately if you notice this icon lit while the car is running. Check the engine oil and pressure level, top-up when low but if not and icon still illuminates, seek for prompt assistance.
Safe to Drive? Yes (Immediate check-up recommended)

(4) Battery Condition:
Cause: A very helpful mark this is – The battery icon, typically, could have two meanings: Either the alternator is not charging or your car’s battery is soon going to be conked off. Don’t panic, because you can still continue to drive but if the destination is far, then better halt at some workshop to know about the exact situation. After all, it’ll be much better than being left stranded on an open road.
Safe to Drive? Yes (Immediate check-up recommended)

(5) Handbrake On:
Cause: An exclamation mark inside the circle signifies that the hand brake / parking brake of your car is lifted. Some fresh drivers generally forget to lift down the handbrake lever before starting off and this is not a nice practice. Please remember to turn off the parking brake before taking off for the sake of your car’s rear brakes. This lamp might also remain illuminated when the brake fluid level is reaching the empty figure.
Safe to Drive? No.

An oxygen sensor (or lambda sensor) is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analysed. It was developed by the Robert Bosch GmbH company during the late 1960s under the supervision of Dr. Günter Bauman
today it is a very key and important component in car, which has to deal with fuel economy and combustion.

How The O2 Sensors Works
Every new car, and most cars produced after 1980, have an oxygen sensor. The sensor is part of the emissions control system and feeds data to the­ engine management computer. The goal of the sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible.
A gasoline engine burns gasoline in the presence of oxygen (see How Car Engines Work for complete details). It turns out that there is a particular ratio of air and gasoline that is "perfect," and that ratio is 14.7:1 (different fuels have different perfect ratios -- the ratio depends on the amount of hydrogen and carbon found in a given amount of fuel). If there is less air than this perfect ratio, then there will be fuel left over after combustion. This is called a rich mixture. Rich mixtures are bad because the unburned fuel creates pollution. If there is more air than this perfect ratio, then there is excess oxygen. This is called a lean mixture. A lean mixture tends to produce more nitrogen-oxide pollutants, and, in some cases, it can cause poor performance and even engine damage.

The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The mechanism in most sensors involves a chemical reaction that generates a voltage (see the patents below for details). The engine's computer looks at the voltage to determine if the mixture is rich or lean, and adjusts the amount of fuel entering the engine accordingly.
The reason why the engine needs the oxygen sensor is because the amount of oxygen that the engine can pull in depends on all sorts of things, such as the altitude, the temperature of the air, the temperature of the engine, the barometric pressure, the load on the engine, etc.

When the oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing. Your car performs poorly and uses more fuel than it needs to burn to enable it keep at optimal performance
