The nightmare of almost every driver is having their check engine light come on. This is because this light can mean so many things from large, expensive fixes to simple tune ups. This light should not elicit fear and loathing in vehicle owners. There are pretty much five main reasons why this light would come on, and simple solutions to make it go out.

First Steps To Take

When the light comes on, before running to a mechanic and dropping a couple thousand dollars, there are a few things that may offer a solution. First of all check to make sure that the gas cap is fully on and not cracked. The drop in compression in the gas tank can cause the light to come on. One may also want to check their belts, hoses, and oil levels which are all factors …show more content…
The oxygen sensor is one way in which your vehicle monitors the oxygen levels in the engine. The oxygen sensor monitors how much fuel is burned in relation to the oxygen levels. If this sensor goes out or is faulty in its operation it can cause a signifigant decrease in the gas mileage the car will give. If the issue is this sensor and it is faulty it can seriously harm the catalytic convertor also.

Catalytic Converter Failure

If the light comes on and it is not the sensor, it could be the catalytic converter. If this part dies or fails there will be a loss of power for the vehicle. This means the individual steps on the gas and the vehicle does not go faster or struggles to accelerate. If the catalytic convertor is gone or going one will also experience a drastic reduction in gas mileage. When the catalytic converter goes entirely, the vehicle will not remain running.

Bad Air Flow

The air flow sensor controls the fuel air mix. This is important to keep the car running. There are many times when the engine light will be triggered and it is simply an air filter that was installed incorrectly. Checking this is simple and can prevent the vehicle from stalling out all the time, and having increased

Led Light

...A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode, which emits light when activated.[4]When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor. An LED is often small in area (less than 1 mm2) and integrated optical components may be used to shape its radiation pattern.[5] Appearing as practical electronic components in 1962,[6] the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible,ultraviolet, and infrared wavelengths, with very high brightness. Early LEDs were often used as indicator lamps for electronic devices, replacing small incandescent bulbs. They were soon packaged into numeric readouts in the form of seven-segment displays, and were commonly seen in digital clocks. Recent developments in LEDs permit them to be used in environmental and task lighting. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime...

Potential buyers should never bid on a vehicle without driving it. | March 07, 2012 | Steve Lang View Full Screen 4 Photos 1. * * * * Chances are that if a vehicle has been traded in, leased, repossessed or totaled, it will find itself among the nearly 9 million vehicles that are purchased each year in an auto auction — either one that caters to dealers or one that's open to the public. Few people outside of the auto industry ever realize the size and scale of this business. It's second only to Wall Street in terms of sheer volume of items being sold at bid. Auto auctions are capitalism in its purest form, and that's what lures buyers in search of a good used car at a low price. And while there are bargains to be had, there's plenty of potential for disaster, too. I've seen both, and often on the same day. From a $200 Volkswagen to a $200,000 Ferrari, I have personally seen hundreds of thousands of deals come together to the future joy of one party — or the long-term sorrow of another.

...last 10 years have evolved from using gasoline and diesel as a primary power source, and now include features once only seen in luxury cars. Introducing them to a rental car company may give it more of a variety to offer its customers. Introduction This paper is to introduce the idea of the integration of alternate-fueled vehicles into the Lotus Rental Car Company and the feasibility to do so to the Chief Financial Officer. There are numerous factors to consider. A large purchase, especially for vehicles, requires in-depth research and weighing of advantages and disadvantages that need to be evaluated. Alternate Fuel Sources There are a few power source options when looking to buy or lease alternate fueled vehicles; ethanol; flex-fuel; hybrid; electric; and natural gas. Alternate fuel source seem to be attractive for consumers as the high prices for fossil fuels continue to climb. With the purchase of new fuel-saving vehicles in mind, each fuel source will be examined. Each type of fuel does have its own great benefit as well as drawback. Ethanol Ethanol is a fuel that is usually comprised of 10% gasoline and 90% ethanol. The more commonly known mixture is 15% and 85% called E85. Internal combustion engines are able to utilize this type of fuel with modifications made the hose materials used to carry this fuel.

Establishing Ground Rules and Identifying Learning Resources for All Learners

...Establishing Ground Rules and Identifying Learning Resources for all Learners By HABC Level 3 PTLLS Assessment 2 28/11/2011 Assignment 2: Establishing Ground Rules and Identifying Learning Resources for all Learners. My job is to teach functional skills in numeracy and literacy at level 1, and key skills ICT. This is done by using computers so the health and safety is done at the very start of the session along with the location of restrooms, what to do in the event of the fire alarm going off and where the emergency exits are. It is at this point that the ground rules are established. These are set taking into consideration the diversity of the group and how they interact with each other. As we use computers there is to be no drink or food allowed, this also encourages them to get up from their seat to make themselves a drink. It is also requested that they either switch their mobile phones to silent or off completely. Another ground rule is no derogatory remarks or comments, this helps to encourage a support environment. Learners are also encouraged to add their own ground rules to the list as this makes them feel a certain responsibility to the group and that they have ownership of the rules, however, final decisions will always remain with me. An explanation is given for each of the ground rules laid down, i.e., drinking near pc’s can result in spillage, damage to the computers or other learners, and mobile phones going off is a distraction to other...

Euro 4 - Role of Diesel Fuel Injection Systems

...BOSCH. The beyond Euro 4 emission legislation is a challenging goal for diesel engine manufacturers. Lowest emissions with highest engine performance, namely high specific power output, petrol like noise levels, benchmarking low fuel consumption and attractive costs are the targets for development activities of the future engines. Key for the success will be sophisticated fuel injection system which supports all the above mentioned targets. Therefore, BOSCH did launch very early a fundamental project defining the requirements for future injection systems with regard to mixture preparation, maximum injection pressure, rate shaping capability and multiple injections. Using several versatile prototype injection systems a comprehensive engine investigation was accomplished to optimise the system configuration to meet the above targets of diesel engines. Applying the criteria of performance, manufacturing robustness, lifetime durability and costs, the variety has been reduced to a hydraulically amplified diesel injection system, which works with hydraulically amplified injectors. This concept together with a potential evaluation for two different Euro 5 scenarios is given in this paper. Figure 1: Change of diesel engine characteristics On the other hand, the diesel engine faces more and more continuously burdening challenges which are overcome using latest injection technology. While the petrol engines set the benchmark for Noise Vibration Harshness (NHV), the complexity of the overall...

Fire Prevention and Fire Fighting on Board a Ship

...INTRODUCTION Every year more and more ships are lost through fire and collision. Shipboard fire alone, however, results in more total losses of ships than any other form of casualty. The most common causes of shipboard fire are: maintenance, burning and welding are responsible for nearly 40 percent of all outbreaks. Smoking leads to countless fires that break out when no one expects. Lack of attention, spontaneous combustion and electrical faults are the major causes. The engine room is at special risk from flashbacks in oilfired boilers, leaky pipings carrying oil, overheated bearings and even the accumulation of rubbish (oil rags, dirty oil, tins of oil, etc.). According to Mikhail Grigorevich Stavitskii 1983, if most shipboard fires can be prevented, then who is responsible for preventing them? The answer is that fire prevention is the shared duty of each and every member of the crew. No fire prevention effort or program can be successful unless it involves everyone aboard ship. We have noted that every crewmember is responsible for the fire aboard ship. Similarly, every crewmember has a role in the ship's fire prevention program. Because attitude is so much a part of the fire prevention, it is also the most important part of the fire prevention program. So as with the Fire Figthing, if there is a fire aboard ship, everyone aboard ship must form the emergency response team. According to Lobo Gruppe, Oslo 1987, the emergency response team are consist of the following...
