Hi everyone, this is Anna again. Hope you got a great week. Here is introducing our new item for garage door remote control. Low frequency remote with 27Mhz and 40 Mhz for the frequency.
We all know that the regular frequency for garage door remote is 315Mhz, 433Mhz, and 868Mhz. But as the data shows which the low frequency still is popular in EURO countries like Germany, Italy, UK, and France etc..

Hi, my dear readers, this is Anna from QINUO. Hope you still take very good care of yourselves. Knowing that the situation of COVID-19 is getting worse than before. But please do believed the vaccine is coming out soon.
Every one worried about the job, so do i. I am afraid that people have stopped to go out because of the security. And the business of car product will go down very soon. And after checked out some data online, it turns out the used car boom is one of the hottest, and trickiest, coronavirus markets for consumers

Typically the super conductor spark plug wires are designed to upgrade an OE ignition system for high-spark delivery levels for street driven applications. Let's study the basics of spark plug wires and figure out the best spark plug wires for your application.
 
How spark plug wires work?
 
The spark plug wires have a simple job that they carry spark energy from the distributor (or coil) to the terminal of the spark plugs. When the electricity travels to the other end of the plug, and jumps a gap between electrodes to produce the "spark" that ignites the fuel mixture.

 
Like everything else on your car, spark plug wires need to be checked and require periodic changing. If you want to keep the performance of your engine at the optimal level, we recommend you replace your spark plug wires at the same time you replace your spark plugs. Fouled, damaged, or worn out spark plugs can lead to a variety of engine problems, such as misfires, hard starts, increased emissions, poor fuel economy and reduce acceleration. For most vehicles, you should replace your spark plugs every 30,000 miles.
 
How to chose the best spark plug wire from a million different kinds with many different features?
 
1. You need to figure out what your car application is?
 
2. There are three commonly used wire cores for super stock spark plug wires to suppress the electric noise of EMI (electromagnetic interference) and RFI (radio-frequency interference).

• With graphite impregnated fibreglass core usually boast very low RFI, it's very similar to OEM wires. However, the resistance of this core is high which can cause a weak spark and potentially rob you of power.


• With magnatism rubber and Ni-Cr wire winding wrapped aramid fiber core has medium resistance of 500 ohms/ft (± 50 ohms).  The Plug wire with this core for the highest suppression possible.


• Tinned copper core has high RFI and 0 resistance, a low resistance wire can't hurt the performance or durability of your engine. However, the high RFI needs to be considered. With an all-out race car or something with a points or magneto ignition, a low resistance wire may be the way to go in order to maximize the available spark energy.

3. Heat resistance and durability is another concern when it comes to plug wires. The 450 F rated silicone jacket provides the plug wires with high temperature and chemical resistance, but there are two different material boots of silionce rubber and ceramic. The ceramic boot spark plug wires can withstand up to 2,000 F, and the silicone boots spark plug wires withstand up to 450 F.
 
4. Size is the last consideration for the spark plug wires, 8 or 8.5mm spark plug wires are commonly used on most applications. Exceptions would be an all-out race car or a street rod where EMI/RFI suppression is not a concern, but weight and appearance are. In which case, a 5 or 7mm spark plug wires might be a better option. Of course on these types of builds, remember to go with a universal DIY type of wire, which is cut-to-fit. By building your own plug wires you can elect how you would like to route the wires, just make sure they come with the right shaped boot.

Things to consider before selecting an Aftermarket Ignition Coil: Choosing the right aftermarket ignition coil can help you achieve better acceleration and superior racing performance. In order to understand how to choose the right coils let us take a deeper look into the basics of Ignition system and ignition coils.
 
Ignition Coil Basics
The basics of the Ignition system hasn’t changed much over the last few decades. The ignition system consists of an auto ignition coil, distributor, distributor cap, rotor, plug wires and spark plug wires.
The Ignition system relies on ignition coil to create enough spark energy to ignite fuel mixture. The ignition coil creates the spark, and the distributor distributes the sparks to the individual spark plugs at exactly the right time. Normally the spark plugs fire the air/fuel mixture with anywhere from 15,000 to 30,000 volts. But the car battery is only 12 volts. So how does the ignition system deliver such high voltages?
 
That’s where the Ignition coil plays its part. The coil relies on electromagnetic induction to deliver high voltages. An ignition coil has two coils of wire called primary and secondary coils, with loops of wire that form each coil called "turns". The primary coil, usually with a few hundred turns, surrounds the secondary with thousands of turns. When current flows through the primary coil, it creates a magnetic field, and when the flow of primary current stops the magnetic field collapses. More turns on the secondary coil than on the primary coil, will produce a voltage step-up through Induction. Also, when a high current circuit is broken, a momentary voltage spike occurs in the primary coil. The voltage step-up induced in the ignition coil is generally proportional to the Turns Ratio. If there are 100 secondary turns for every one primary turn, then the Turns Ratio will be 100:1. But, increasing the Turns Ratio beyond a certain range will be counterproductive as more voltage means lesser current flows through the secondary coil. For many coils in the market the turns ratio is around 100:1.
 
Apart from the Turns Ratio, the resistance in the primary coil also affects the ignition coil performance. Lesser resistance in the primary windings of the coil allows more current to flow, thereby creating a stronger magnetic field. The primary wires are thinner and needs only thin insulation. The secondary wires are thicker than the primary wires and have more insulation to withstand the higher voltages.
 
Dwell Time
In an Ignition coil it takes some amount of time for magnetic flux to develop to the full potential current and voltage and discharge the stored energy as spark. The Induced voltage doesn’t develop instantaneously. The time required for an Ignition coil to charge up to its full potential is called “dwell’. Dwell is typically expressed in terms of degrees of distributor rotation. For example, in a common V8 engine the dwell is usually 30 degrees (or 30 degrees of distributor rotation).
 
Dwell vs. Engine Speed
The higher the engine speed, the less time is available for the coil to recharge between spark firings. Beyond a certain engine speed, the coil may not have enough time to recharge to its full capacity for the next spark cycle and this insufficient energy results in misfiring.
 
So, to summarize we can say that the Ignition coil performance is dependent on the Turns Ratio, Inductance and Coil Resistance, provided the ‘dwell’ is sufficient for a full recharge between firings. In a conventional Ignition system, the dwell is fixed and the engine will start to misfire if the RPM goes beyond the ‘dwell’ limit, resulting in loss of power. This causes ignition system crashes and the engine may coast till the coil recharges resulting in loss of power and speed.  Ignition systems which uses electronics to predict and adjust the dwell helps solve this to a certain extent. But all conventional Inductive Ignition systems are susceptible to spark roll off at higher rpm despite the electronic ignition systems.
 
Due to this reason many racers replace their stock induction system with a high-performance aftermarket ignition system. There are many designs available in the aftermarket that ensures high performance. Every engine is different from each other and so it becomes important to select the right aftermarket solutions to maximize performance. The basics you need to consider while selecting a coil are:
·       Primary Resistance
·       Turns Ratio
·       Secondary Resistance
·       Maximum Voltage
·       Inductance
·       Peak Current
·       Spark Duration
·       Dwell Time vs Engine RPM
·       Ignition system compatibility

1. How can I elongate the use life of lamp?
The use life of lamp is decided by actual use time and use time. For example, in case user need to use lamp for long time and power on and off lamp and switch functions in a day for many times, the use life of lamp is reduced. When you want power on and off lamp cabinet for several times in an hour, don`t power off the lamp cabinet. Generally, powering on lamp is equal to using lamp for one hour. Please power off lamp cabinet in case of not using lamp for long time. In case of unnecessary condition, don`t try to switch from different light sources, elongating effective use life of lamp.
