Spark plugs channel electrical current to ignite fuel in combustion engines. They come in different types like iridium and platinum. Symptoms of bad spark plugs include excess emissions, lack of power, and rough idle. Changing spark plugs requires tools like a ratchet, socket, and extensions. The process involves removing old plugs, measuring the gap, cleaning threads, and installing new plugs.

Regular testing and replacement of underperforming spark plugs provides benefits like lower emissions, better fuel economy, and trouble-free engine operation. The machine allows for efficient testing of spark plugs.
Laser Ignition for Internal Combustion Engines 3228Abhishek Hingmire
?
Laser ignition is being explored as an alternative to spark plug ignition for internal combustion engines. Lasers can ignite leaner fuel mixtures than spark plugs due to their concentrated optical energy without electrodes. They also allow for multiple ignition points and different ignition locations in the combustion chamber. Researchers have created a small high-powered ceramic laser that can generate the necessary energy levels for ignition. Laser ignition systems could reduce emissions, increase efficiency, and have a longer lifetime than spark plugs, though high costs currently limit commercial applications. Testing on research engines shows lasers' potential to ignite alternative fuels and enable more efficient combustion.

This presentation is dedicated to ignition systems for Internal Combustion Engines (ICE). The Ignition System is paramount for every car, motorcycle, truck or bus that runs an ICE based on gasoline, alcohol or Liquefied Petroleum Gas (LPG). It controls the timings when the spark plugs are fired, therefore igniting the air-fuel mixture in the combustion chamber. The Ignition System is one of the major players in what concerns the performance of the engine in terms of output power, pollutant emissions and fuel consumption.
This document discusses laser ignition as an alternative to spark plug ignition for combustion engines. It begins with an introduction to laser ignition and its advantages over spark plugs, such as enabling leaner fuel mixtures with lower emissions and longer lifetime. It then explains how laser ignition works by focusing a laser beam to generate a high-temperature plasma that ignites the fuel-air mixture. The document presents the experimental setup used to test laser ignition on various fuels and an engine. It finds that laser ignition allows for more precise ignition timing and locations compared to spark plugs. In conclusion, while laser ignition has benefits, commercial systems are not yet available due to high costs.

Laser ignition is an alternative method for igniting compressed gaseous mixture of fuel and air. The method is based on laser devices that produce short but powerful flashes regardless of the pressure in the combustion chamber. Usually, high voltage spark plugs are good enough for automotive use, as the typical compression ratio of an otto cycle internal combustion engine is around 10:1 and in some rare cases reach 14:1. However, fuels such as natural gas or methanol can withstand high compression without self ignition. This allows higher compression ratios, because it is economically reasonable, as the fuel efficiency of such engines is high. Using high compression ratio and high pressure requires special spark plugs that are expensive and their electrodes still wear out. Thus, even expensive laser ignition systems could be economical, because they would last longer
