Modern vehicles’ electronics systems:

As we advance through the decades with progression in electronics, science and technology we must not forget the basis of our modern day sources of transportation. I would like to explicate a system in which I am fairly familiar with and have been the highlights of my interests. This is the recent power developments and characteristics of a four-cycle engine. Also known as the Otto cycle engine, the four-stroke engine works of off many mechanical components that simply derive power on the basic mixture of air and fuel. Hence the name “four cycle” such an engine consists of four complete strokes or cycles to consume and make power. With the completion of four cycles, intake, compression, power and exhaust, such a machine can thoroughly and consistently make power.

Today, manufacturers are concerned with meeting emissions standards, which is why many changes have been made to the four-cycle engine. Some changes may consist of variable valve timing (VVT); programmable fuel injection (Pgm-Fi) with electronically controlled fuel mapping, and turbochargers. Those all can increase power output, and some, efficiency.
Many parts and components have taken over such standards and exclusively expresses the advantages, due to more intake and less fuel. One device is called a turbocharger system. Most cars with engines are naturally aspirated, which means the engine sucks air through the intake manifold and completes the intake stroke through means of normal atmospheric pressures. Optimum barometric pressure readings of NA engines are about 1.0. The NA engine is restricted to produce it’s maximum power output due to the loss of volumetric efficiency (air forced into the cylinders with a mixture of gasoline). The ratio of air to fuel is very important in determining horsepower. The turbocharger can do all this and much more. Here is a brief background.

The turbocharger is a device mounted to the intake manifold. It is a circular air pump operated by exhaust gases. It consists of a compressor on the intake side, shaft in the middle and turbine on the exhaust side. It is used to improve engine performance through means of a higher air compression status and the same or less amount of fuel to the cylinders. The turbocharger’s compressor can spin up to 100,000 revolutions per minute. One disadvantage of such a turbo-charged engine application is the stress of mechanical parts due to heat. I may suggest an inter-cooler to provide cooling efficiency of exhaust gases inside the turbocharger. This is mostly important because high temperatures of gases contain less oxygen than normal cool temperatures. Thus, this may result in a loss of performance and throttle acceleration.

The turbocharger can be very useful for dramatic horsepower gains and engine performance, although installing such an application may sacrifice reliability and engine longevity, with the addition of changes in electronics and ECU’s. Many who own import cars are buying such systems because of overall 30-60% horsepower gains.

Another example is the expanded technology of intake and exhaust valves. Valves work off of the rotation of an engine’s camshaft. These newly designed valves actuate by electronics inside of the engine. Variable Valve Timing also known as (VVT) is definitely a huge change in the advancement of gas mileage, efficiency, and power. If a car with VVT has sixteen intake valves, and sixteen exhausts valves, only sixteen of the thirty-two valves work, not thirty-two. Due to the electronic shutdown of the valves, only all thirty- two valves will work at a specified rpm range. Thus, reducing fuel consumption and more air intake, making plenty more lb. of Ft. torque.
I would also like to explain the programmable fuel injection system (Pgm-Fi). Many engines today have been developed with electronic fuel injection. Every engine is either carbuerated, or fed fuel through an injector of each cylinder by electronics. The newly revamped EFI engine is the result of electronic injectors. Controlled electronically, these injectors can account for finer fuel atomization. The finer fuel atomization causes the fuel to be dispersed evenly, and even finer inside the cylinder before the power stroke. This causes less fuel to burn longer, decrease rapid combustion, and the result, more power!

We can conclude that cars today have undergone extensive changes and developments in four-stroke technology. I feel that efficiency of automobiles and power is one in the same. I really like cars with excellent performance and gas mileage. Take for an example Honda’s automobiles. Their cars from the factory can be fast, but most of all, they are very efficient. This is the new age of automobiles. This is only the very basis of engineering excellence, and the ongoing determination to research and develop the world’s most powerful and efficient automobiles.

Remote Car Starters

Cars have always been a natural target for thieves, as they can be smoothly sold at a good price. Today, car thefts are rising at an alarming rate, and it is said that a car is stolen every 20 seconds. In order to curtail the rising trend in car thefts, alarm companies are making highly improved and new alarm systems for cars. They are proving to be very handy and effective and are recommended by most car dealers.
Remote start car alarms (remote car starters) are the latest improvement and have amazing high tech features. These systems are outfitted with the latest technology of antiscan and antigrab. The multiple programmable features of the remote start car alarms, makes them very practical for car users. These alarms are also operational in cold weather. The exclusively designed remote is set with a LCD display that provides the user with a car/alarm status.

The remote start works in all automatic, manual and diesel cars. The anti-carjacking feature makes this alarm system highly reliable. These alarms provide maximum security to a car because of the built in vibrating sensors that are fitted in the door, boot, and bonnet. They also have a silent arm, disarm and alert feature. They provide, additional optional features like total closure and remote boot release, and come with smart LED indicators, backlights and automatically activated interior lighting. The remotes are very user friendly, as they have an inbuilt query function, real-time clock and an alarm clock.

Remote start car alarms are often expensive, but if a person owns an expensive car, then a remote car alarm is a sensible investment. Keyless Car Starters

Home Speakers - Tips

Clear sound is considered to be one of the most important elements of a great home theater experience. Quality sound really brings film to life and that fact spurs many home theater aficionados to select their home speakers and sound equipment with great care.

Too often, though, the speakers that sounded great in the listening room don’t pack the same punch when installed at home. The issue is usually related to speaker positioning.

There are a few factors anyone should consider when installing home speakers. One should be aware of proper distancing, height and angling (also referred to as toe-in). Sometimes the perfect set-up is outlined in the owner’s manuals and documentation that come with the speakers. In other cases, it’s necessary to evaluate proper positioning with a “trial and error” technique.

If your speakers aren’t bringing the movies to life for your home theater system, don’t give up and go purchase a new sound system until you first double-check the positioning of your speakers. Even small adjustments can have a huge impact.

By finding the optimal positioning for your speakers, you can breathe new life in what you may have believed to be an inferior speaker. You can also begin to enjoy the movies the way you had hoped to when you first decided to invest in a home theater system.
