hStarter is a small but powerful electric motor that is attached to the engine body and turns the drive flywheel. The flywheel, which is connected to the end of the crankshaft, and the pistons, which are responsible for the suction and compression of air in the cylinders, are connected to the crankshaft by the connecting rod. As a result, with starting, the flywheel, crankshaft and finally the pistons start working and the car engine starts. Of course, as it was said, the car starter has been made in different types from the beginning until today, such as electric , is the most common of them. Once upon a time, the most common way to start the car engine was to use manual handles.

If we consider the end of all internal combustion engines, we reach a device called flywheel. In fact, in front of the engines, there is a crankshaft pulley on which the timing belt and other belts are placed, and the end of the engine is the flywheel. One of the functions of the flywheel, or the flywheel, is to place the disc and the clutch plate in cars with manual transmission or the turbine in cars with automatic transmission, on it and communicate for power transmission.
Around the flywheel is a large gear called the starter gear. These teeth are used to position the gear of the starter head and turn it, thus turning on the engine. When the engine is turned on and the switch is released, the current is removed from the starter, and as a result, the starter gear moves back one step. In short, it can be said that in cars where the engine is located along the length of the car, the starter is installed at the end of the engine, which may be on one side of the engine, or in some engines, it is installed in the middle of the engine and above it. In engines that are placed transversely, the starter is usually located in front of the engine and it is easily accessible from the top of the engine.
Buy Car Starter
Car starter system, because it is closed on the engine shell or gearbox, has a special and unique design for all types of engines. However, it is possible to prepare a car starter for another engine by changing the starter head in some cases. Although the starter type of an engine can be changed; But usually, one type of car starter cannot be installed instead of another type, because the location of the starter, especially in today's engines, is completely special and unique. In addition, the number of gear starter gears is also important, and their number being less or more compared to the standard mode, even by the size of one gear, prevents the starter gear from fully engaging with the flywheel and causes problems with starting.
Types of car starters
The car starting system has been made in different types since the beginning of the car until today. Although today, electric starters are fully used in the automotive industry; But in the past, different models of starters have been used to start engines.
Electric Start
is the most common type of car starter, widely used in gasoline and diesel cars since the 30s. The electric current is transferred to the starter, which is actually an electric motor, and this electric motor can rotate the flywheel gear with its own mechanism. This electric motor rotates at about 1000 rpm, which can increase the engine to 100 rpm and start the engine.
Pneumatic starter
Pneumatic starters were used relatively widely in heavy vehicles before electric starters came into use, and they were also somewhat popular in passenger cars. In heavy vehicles, due to having air tanks for the braking system, this air pressure is also used to rotate the flywheel. The high wind pressure can spin the flywheel as soon as it is released and lead to the engine starting.
Hydraulic starter
Hydraulic starters have also existed in the past; But their new generation is just becoming popular for diesel engines, especially with high cylinder numbers. Hydraulic starters have more power than electric and air starters, and because there is no electric current in them, they do not have problems such as electrical connections and weakness in starting in cold weather. These starters are actually a hydromotor that works with high-pressure hydraulic flow. This current can be supplied with a small electric motor or with a hand and foot lever. In addition, the system of these starters is designed in such a way that the engine charges the high pressure for the next starts so that the driver does not need to make efforts for the next times.
Starter Increase
Inertia starters are suitable for small and small engines. The advantage of these startups is that their work system is indirectly related to Flywheel. This means that first the electric motor rotates the starter gear. When this rotation reaches the optimum, it moves forward and engages the flywheel and turns it on. Another advantage of this system is the interruption of the starting operation as soon as the engine is turned on.
Predetermined starter
These types of starters are being used in today's new cars. One of the problems of common electric starters is the failure of starter gears and flywheel gears over time and due to their connection type. Because the starter gear moves towards the fixed flywheel gear with a high speed, and after colliding with it, it is pulled out from the flywheel gears. This type of conflict causes wear of the starter gear and the flywheel gear gradually. But in pre-engaged starters, there is a connection between the starter gear and the flywheel gear before the starter gear starts rotating, and then the electric motor starts. This mechanism increases the life of the starter gear and flywheel gear.
Heavy Cars Start
Heavy vehicles have different starters in terms of air, hydraulic and electric, but nowadays only electric and hydraulic starters are used. But the point that we should know about the starter of heavy and commercial vehicles is that some old heavy vehicles have 12 volt starters; But since several decades, most heavy vehicles use 24V starters.
How to replace and install the starter
Replacement and installation of the starter is a relatively professional and specialized work. This part, especially in engines that are installed longitudinally, requires a service hole, and in engines that are installed transversely in the car, due to the crowding around the engine, it requires expertise and skill. We just have to keep in mind that before opening any electrical part in the car, we must open the battery connections.
Car starter is the first part used to start the car. As a result of its failure, especially in cars with automatic transmission, the car cannot be used. The car starter has existed since the very first car in the world, the Benz Patent Wagon, and until today, different types of it have been installed on different cars.
