How the Ford Model T Ignition System Works
The Ford Model T ignition system used a trembler coil, also known as a buzz coil or vibrator coil, which was a type of high-voltage ignition coil. Its distinguishing feature was a vibrating magnetically-activated contact called a trembler or interrupter, which broke the primary current, generating multiple sparks during each cylinder’s power stroke.
The Model T Ford featured a basic electrical system of magneto and coil per cylinder ignition system, without provision for electric starting or lighting.
The ignition system of the Ford Model T used a flywheel-mounted magneto to produce the current necessary to produce a spark to initiate combustion. This current was distributed by the timer to one of the four trembler coils, one for each cylinder. The coil stepped up the voltage and discharged it to the spark plug in the cylinder. Ignition timing was adjusted manually by using the spark advance lever mounted on the steering column, which rotated the timer, advancing or retarding the ignition timing.
The primary circuit of the Model T ignition coil is an inductor. When voltage is applied to the primary circuit of a coil, the current begins to build.
Henry Ford insisted that the Model T have a self-contained power source for the ignition system so owners would not have to rely upon battery power. This was implemented in the form of the internal flywheel-driven alternating current generator, known as the Model T Magneto, which had sixteen permanent magnets mounted on the flywheel rotating near a ring of sixteen fixed field windings to produce the necessary current.
The ignition system of the Model T Ford consisted of a separate, easily removed sparking coil for each cylinder and a ‘timer’ that selected the appropriate coil for the cylinder that was about to fire.
In summary, the Ford Model T ignition system used a trembler coil to generate multiple sparks during each cylinder’s power stroke, with the necessary current produced by a flywheel-mounted magneto and distributed to the spark plugs through a timer .
I hope this provides a clear understanding of how the Ford Model T ignition system worked! If you have any more questions, feel free to ask.

How does a Model T Ford ignition work?
One of the many fascinating design aspects of the Model T Ford is its ignition system which consists of a separate, easily removed sparking coil for each cylinder and a ‘timer’ that is driven directly off the end of the camshaft and which selects the appropriate coil for the cylinder that is about to fire.
What was special about the T model Ford?
The Model T became famous for the stunts it could perform including climbing the stairs of the Tennessee State Capitol and reaching the top of Pikes Peak. After the test of his own product, the vehicle was shipped to its first customer on October 1, 1908.
How do you start a Model T car?
If the car has a starter, press the floor mounted starter button briefly. Most Model T’s will start in one or two pulls of the crank, or a brief touch of the starter button. As soon as the engine starts you must pull the spark lever (left) down about 1/2 way.
How did you start a Ford Model T?
Now I mentioned that the the Model T has no accelerator pedal on the floor. That’s actually controlled with this lever.
Can you legally drive a Ford Model T?
Yes, but it’s top speed is so low that it would only be capable of driving in residential streets.
How does the Model T work and what does it do?
The engine was simple and efficient, with all four cylinders cast in a single block and the cylinder head detachable for easy access and repair. The engine generated 20 horsepower and propelled the car to modest top speeds of 40–45 miles per hour (65–70 km/h).
How do you start a Model T engine?
Open. Then we’re going to go ahead and leave the ignition key to the off position pull on the choke. And press the starter button for four to five revolutions.
Did the Model T have a key ignition?
Inserting an ignition key, like the one shown here, was just one step in starting a pre-1920 Model T. Drivers had to make other adjustments and hand crank the engine to start the vehicle. Inserting an ignition key, like the one shown here, was just one step in starting a pre-1920 Model T.
What are the key specifics of the Model T engine?
Engine. The Model T has a front-mounted 177-cubic-inch (2.9 L) inline four-cylinder engine, producing 20 hp (15 kW), for a top speed of 42 mph (68 km/h). According to Ford Motor Company, the Model T had fuel economy on the order of 13–21 mpg‑US (16–25 mpg‑imp; 18–11 L/100 km).
Does a Model T have a clutch?
The middle, halfway-down position puts the Model T into neutral, while pressing the pedal to the floor puts the car into the “low gear.” Getting moving and into first gear requires slowly pressing the clutch down while easing onto the throttle—using the steering-wheel-mounted stalk, remember—and off the brake.
