DENSO Aftermarket: Reliable Car Ignition Solutions for Optimal Performance

 At DENSO, our mission is to build a recognized brand with a focus on reliability and environmental protection. We provide distinctive car care solutions and strive to innovate for a greener future.

High-Performance Spark Plugs

A successful ignition is the key to starting your car reliably and ensuring optimal engine performance. Known as the “heart of the engine”, spark plugs play a critical role in igniting the fuel-air mixture in gasoline engines, generating power efficiently.

The spark plug works by passing a high voltage between its centre and ground electrodes, creating a spark that triggers combustion. Though this spark lasts only about 1/1,000 of a second, it must be precisely and reliably timed to ensure smooth engine operation, improve fuel efficiency, and reduce carbon emissions.

FAQs

Q1: How does an ignition system work?
It depends on the type of system. But in simple terms, a conventional ignition system generates a very high voltage from the car's battery, sending this to each sparkplug and igniting the fuel-air mixture in a petrol engine's combustion chambers to start the engine. The coil is the component that produces this high voltage. A distributor cap provides the electrical connection between the coil and spark plugs in conventional mechanical and electronic ignition systems.

Q2: What are the types of ignition systems?
There are four types of ignition systems: conventional breaker-point (mechanical) ignitions, high energy (electronic) ignition, distributor-less (waste spark) ignition, and coil-on-plug ignition.

Q3: What are the main components of a conventional ignition system?
The main components are a coil pack, an ignition module, a crankshaft reluctor ring, a magnetic sensor, and an electronic control module. The ignition module controls the primary circuits to the coils, turning them on and off.
