Transistorized ignition

Types of Transistorized Ignition

There are three main types of transistorized ignition systems, each with its unique method of signal control and switching.

• Magneto Ignition System

  This system is mainly used in small engines and older cars. It utilizes magnets to produce a current. When the engine turns, the magnets move past a coil, generating a current. This is all done without any external power source, which makes it great for small engines.

• Capacitor Discharge Ignition (CDI)

  CDI systems are often found in motorcycles, some older cars, and small engines. These systems are known for their quick and powerful sparks. They work by charging a capacitor (battery) as the engine turns. This charged capacitor discharges through the ignition coil, creating a strong spark. The lack of moving parts makes CDI systems reliable and low-maintenance.

• Transistor Ignition Coil

  Transistor ignition coils are the most common in modern vehicles. They use one or more coils to transform the low voltage of the battery into a high voltage. The battery supplies power to the primary winding of the coil, while the secondary winding generates the high voltage. A transistor (usually a MOSFET) controls the current in the primary winding, allowing for precise control of the spark timing and duration. This results in more efficient combustion, better fuel economy, and reduced emissions. Some vehicles may have multiple ignition coils, such as coil-on-plug (COP) arrangements, where each cylinder has its coil, further improving ignition control and performance.

Specifcation & Maintenance of Transistorized Ignition

The specifications of transistorized ignition systems vary depending on the make, model, and design of the vehicle. However, some common specifications include the following:

• Power Supply

  Power supply specifications include the voltage level and current capacity provided to the ignition system. The ignition system may use a 12V power supply with a current capacity ranging from 1-5A.

• Coil Resistance

  The ignition coil in the transistorized ignition system has primary and secondary windings with specific resistances. The primary resistance may range from 0.5-3 ohms, while the secondary resistance may range from 5000-15000 ohms.

• Signal Input

  Signal input specifications include the type of signal sent from the crankshaft position sensor or camshaft position sensor to the ignition control module. The signal input may be digital with square wave pulses or analog with varying voltage levels.

• Operating Temperature

  The operating temperature of the components in the transistorized ignition system is important. This includes the ignition control module, power transistors, and ignition coils. These components can have operating temperatures ranging from -40 to 125 degrees Celsius.

• Emissions Control

  The emissions control specifications for the ignition system are how it interacts with other engine control systems to minimize emissions. These include the ignition system's timing, the air-fuel ratio, and the exhaust gas recirculation.

Maintaining a transistorized ignition system is crucial for optimal vehicle performance and reliability. Here are some maintenance tips:

• Regular Inspection: Carry out regular inspections of the ignition components, including the spark plugs, ignition coils, and wires. Worn-out spark plugs or damaged ignition coils can cause misfires and affect engine performance.
• Check Connections: Loose or corroded electrical connections can cause ignition system failures. Check all electrical connections in the ignition system and ensure they are tight and free of corrosion.
• Clean Components: Dust, dirt, and contaminants can accumulate on ignition system components. This includes the ignition control module and the ignition coils, affecting their performance. Clean these components using a soft brush or a clean, dry cloth.
• Follow Manufacturer Recommendations: Adhere to the maintenance schedule and recommendations provided in the vehicle's owner manual. This includes replacing ignition components like spark plugs at the recommended intervals.
• Use Quality Parts: When replacing ignition components, use high-quality parts that meet the manufacturer's specifications. This ensures compatibility and reliability.
• Monitor Engine Performance: Be on the lookout for signs of ignition system problems, such as rough idling, reduced power, or check engine light. Address these issues promptly to prevent further damage.

How to choose Transistorized Ignition

When choosing the right transistorized ignition system for a business, consider the following factors:

• Engine requirements

  One's choice of ignition system should align with the engine's needs. High-performance engines typically benefit from a TFI system, which provides more reliable and stronger spark, while standard engines can function adequately with simpler systems.

• Vehicle compatibility

  Ensuring that the chosen ignition system is compatible with the vehicle is crucial. Different vehicles require distinct ignition systems, and using an incompatible system can lead to engine performance issues.

• Quality and reliability

  Selecting a well-known brand that offers high-quality and dependable components is essential. This ensures the longevity of the ignition system and its consistent performance over time.

• Budget

  Ignition systems and components can be found at various price points. It's important to consider the budget but also to remember that investing in a quality system can lead to better engine performance and potentially lower maintenance costs in the long run.

• Installation and maintenance

  Consider the ease of installation and the required maintenance of the chosen ignition system. Some systems might be more complex to install or require more frequent maintenance than others.

How to DIY and replace Transistorized Ignition

Below are some steps for replacing the transistorized ignition system:

• 1. Gather the necessary tools: To complete the project, have a screwdriver set, pliers, an electrical multimeter, and any specialized ignition system components on hand.
• 2. Disconnect the battery: To avoid electrical shorts or damage, disconnect the battery before working with the ignition system.
• 3. Access the ignition components: Depending on the vehicle, remove any necessary covers or access panels to reach the ignition components.
• 4. Remove the old points ignition system: Take note of the wiring connections and remove the old points ignition system, including the distributor cap, rotor, and ignition points.
• 5. Install the new transistorized ignition system: Follow the manufacturer's instructions to install the new transistorized ignition system, including mounting the ignition coil and connecting the wiring.
• 6. Set the timing: Use a timing light to set the ignition timing according to the manufacturer's specifications.
• 7. Reassemble and test: Reassemble any removed components, reconnect the battery, and start the engine to test the new ignition system.
