Thermostat valve

 Does the engine need to warm up for a car to run efficiently?


         Here we discuss whether engine warm-up is essential to maintain a car's fuel efficiency. In the study of engine operation, the energy of an engine is generated by converting the chemical energy of the fuel into kinetic energy with the help of thermal energy, and the generated thermal energy leaves the system through the following percentage.

✔️ By exhaust gas - approx 40%
✔️ By cooling system - approx 30%
✔️ By friction - approx 5%
✔️ Effective energy - approx 25%

      In the study of the above note, it is clear that most of the total energy generated by the engine is wasted without use. That is, about 25% of the total energy generated is used for driving the car. An engine is an energy conversion machine that performs many mechanical functions. There are a large number of parts that move in contact with each other inside, and there is a temperature that an engine must maintain to minimize friction between them. It is around 1000C and only at that temperature will the engine run at high efficiency. But the operating temperature of some modern cars is higher than 1000C.

       නමුත් එන්ජිමක ක්‍රියාකාරී උෂ්ණත්වය පවත්වා ගැනීම එතරම් පහසු නොවේ. එයට හේතුව එන්ජිමේ සිසිලනය සඳහා භාවිතා කරන සිසිලන පද්ධතිය එන්ජිම ක්‍රියාත්මක කිරීමත් සමග ක්‍රියාත්මක වීමයි.  මෙහිදී එන්ජිමේ සිසිලන සඳහා භාවිතා කරන සිසිලන ද්‍රව එන්ජිම පුරා නිරන්තරයෙන් සංසරණය වන අතර සිසිල් අවස්ථාවේදී එන්ජිමේ ප්‍රශස්ථ උෂ්ණත්වය පවත්වා ගැනීමට හැකි වන ලෙසින් එන්ජිමෙහි යම් යාන්ත්‍රණයක් නිර්මාණය කර තිබේ. එම නිසා එන්ජිමේ ක්‍රියාකාරී උෂ්ණත්වයට පත්වීමට යම් කාලයක් ගතවේ. මෙලෙස එන්ජිමේ උෂ්ණත්වය අඩු කාලයකින් ක්‍රියාකාරී උෂ්ණත්වයට පත්කරගැනීම  සඳහා භාවිතා කරන උපාංගය වන්නේ උෂ්ණත්ව පාලක වෑල්වයයි(Thermostat Valve).

මෙම වෑල්වය මගින් එන්ජිම පුරා ගමන් කරන සිසිලන ද්‍රව(Coolant Liquid) රේඩියේටරය හරහා ගමන් කිරීම වළක්වා තිබෙන අතර එමගින් එන්ජිම සිසිල් වීම වළක්වනු ලබයි. නමුත් එන්ජිමෙහි සඳහන් කළ ක්‍රියාකාරි උෂ්ණත්වය ඉක්මවීමත් සමග වෑල්වය විවෘත වී සිසිලන ද්‍රව රේඩියේටරය හරහා ගමන් කිරීමට මාර්ගය සකස් කරයි. එමගින් ක්‍රියාකාරී උෂ්ණත්වයට වඩා වැඩිවන එන්ජිමේ උෂ්ණත්වය අඩු කර ගැනීමට හැකියාවක් තිබේ   
.



      It is clear that the temperature control valve is very important for the efficiency of an engine. During certain repairs and fault conditions, this valve is removed, causing coolant to continuously circulate throughout the engine while the engine is running, and the engine may not even reach operating temperature. This reduces the amount of thermal energy obtained from the engine's fuel combustion that is converted into mechanical energy. Therefore, to get more mechanical power, more fuel must be burned, so the fuel consumption of the engine increases significantly.

      Thus, this article brings out the need for a thermostat valve in the conventional cooling system. It has been decided to bring to you in the following articles the technologies of cooling systems used by the manufacturer to increase the thermal efficiency used in modern cars.  In addition, we are ready to provide information and inform you about the knowledge you need to know if you are a car enthusiast and drive a car.

DTS-i Technology

Image
 What is DTS-i technology?     DTSi or Digital Twin Spark Ignition System is a technology developed and patented by Bajaj Auto Limited.     It was first used in Bajaj's Pulsar and Avenger models.  When it was introduced to the market, it was introduced as a unique creation that both saves fuel and improves engine performance.              In automotive engineering technology, perfect combustion cannot be achieved due to the loss of one spark plug in the combustion chamber and the inability to burn the fuel instantaneously. However, the DTSi engine tries to achieve complete combustion by speeding up the combustion process as much as possible.    The DTSi engine delivers twice the power of a typical two-stroke engine and a significant power-to-power ratio compared to several four-stroke engines.     It can also adjust the idle speed and avoid fuel over-burning during intermittent pick-up an...

Pickup coil , trigger coil , puls coil

Image
Pulse coil / pickup coil  What do you mean?   This is made by putting a small piece of magnet / magnet in front of a very thin wire rod.... The magnetic lines of this magnet have always passed through the coil.... If you move a metal part in front of this magnet, the magnetic lines through the rod will change. We know that if a magnet is moved in front of a wire, a small voltage is generated in the wire... Here too, a small alternating current / AC electricity is produced. It is installed nearby... there is a part like a small groove in the ply wheel... That part is fixed in such a way that it goes exactly to the pulse coil when the spark is to be given in the engine... The CDI Unit/control unit knows the time/opportunity to give the spark through this device... It has two wires, one is connected to the vehicle. It is fixed, it is grounded... the other wire goes to the CDI unit...

EGR System

EGR System  Exhaust gas recirculation (EGR) is a method of controlling NOx emissions applicable to a wide range of diesel engines, from light, medium and heavy duty diesel. engines to two-stroke low speed engines. These EGR systems are also found in many categories of engines with auto cycles (typically four-stroke engines)...,        Most EGR systems include the following major hardware components: 01: One or more EGR control valves 02: One or more EGR coolers 03: Pipes, flanges and gaskets A number of other specialized components are possible in different types of systems.     Common examples are mixers using venturi nozzles (venturi mixers or venturi pumps) and EGR pumps, also known as EGR blowers, which are powered by an electric motor or mechanical connection to the       engine. A small tube from the exhaust pipe takes part of the exhaust gas from the intake... Because that part of the gas is very hot...
