In course of time, with the development of larger engines that had higher compression ratios, using of the hand crank became nearly impossible. As a result, a new invention called a self-starter motor was introduced. By 1920, almost every driver could boast of having this unit under their hood. Today, it is a must-have component for every vehicle that is on the road.

The starter is the first thing to engage when you're setting the car in motion. Yet, the unit doesn't start the engine by itself. It works in unison with other starting system parts. Once you insert the ignition key and turn it, the solenoid switch is on, which allows an electric current from the batteries to travel to the starter motor. The motor gears mesh with a flywheel gear so the engine is rotating as soon as the starter is activated.

Since the engine turns much faster than the starter, there must be a device that disengages the gears after starting to prevent their damage. The Bendix drive does the job. It controls the starter's pinion gear and can be found only within the electric starter motor, which is the most usual type. Used on small gasoline and diesel engines, the electric starter has a solenoid switch, which acts as a principal power switch to begin the starter operation. It activates the battery which in its turn sends low-current power to the starter solenoid. The solenoid forces the drive pinion on the starter drive shaft and meshes with the flywheel gear that is on the engine.

Except the electric, there are also pneumatic and auxiliary starters. The auxiliary or pony starter engine usually comes in pair with a larger, high-powered diesel engine. Sometimes, they have a common oil supply and cooling system. Once the pony engine warms up, it circulates warm oil and coolant in the diesel engine. The pneumatic starter is seldom used on diesel and gas turbine engines, while it's the best type for the most trucks. This mechanism consists of a pressure tank, air compressor, and geared turbine, and works much the same as the electric starter. When the engine starts running, it powers the compressor to recharge the tank.

Being a mechanical device, the starter is often subjected to various road hazards and changing weather conditions, as well as driver's behavior. The unbearably cold air may get the vehicle's battery drained or have it collapsed from excessive oil viscosity. Too much heat can cause prolonged start up of the engine. The starter motor bearings that ensure rotational movement between parts can fail because of normal wear and tear. When these or any other problems arise, the wisest way to solve them is to have a professional maintenance service that will detect the causes and come up with a possible solution.

    Starter motors and alternators have a tough job. Starter motors are high-torque motors which must have the ability to turn over, or crank, an engine under varying weather and mechanical conditions. Without a functioning starter motor, you simply cannot start up a modern vehicle's engine.
