Spark Plug Function

Engines which are the main driving force of the modern day vehicles comprise of two main types, depending upon the type of the fuel being used in the engine. Hence the engines can be categorized as spark ignition (Petrol) vehicles and compression ignition (diesel) vehicles. And the most important part in the petrol vehicle which ensures constant sustainable life to the petrol engine cars is the spark plug which is the sole agent responsible to ignite the petrol and make it burn which in turn will generate the power for the petrol vehicles. Best spark plugs available in the market are used for getting the optimum performance of the cars. The Spark plugs are therefore the most crucial part of ignition system of cars. Also since the spark plugs are one of the directly exposed to combustion parts of the engine, the spark plugs are designed to bear high temperatures of combustion while an engine is running.

Spark Plug Construction

There are following three main parts of a spark plug

• Center electrode
• Ground electrode
• Insulation between two electrodes

Moreover, there is a body shell, the sealing ring and the gasket washer. The insulator between two electrodes, play an important role in maintaining temperature. Outer insulation prevents hot gases from leakage. Spark plug wires attach it with engine and make it the part of whole ignition system.

If continuous ignition occur in spark plug, it would be difficult to control temperature of central electrode as it is constantly increasing. Therefore for maintaining certain temperature level, Spark plug gaps are important. There must be some resistance in combustion to make spark gaps possible.

Therefore a best spark plug should have following characteristics.

• Should maintain certain (engine operating) temperature
• Insulation among electrodes
• External insulation
• Supports reasonable spark gaps

Spark plugs require proper maintenance and need to be replaced for smooth functioning of car engines. One must know spark plug symptoms to know when to replace a spark plug. There are some simple steps that one can follow to check whether spark plug needs to be replaced or not.

Due to ignition process exhaust gases are released, which is the main source of accumulation of carbon gases on spark plug, which in result make it covered with black color (carbon accumulation). This is the indication that the spark plug should be cleaned or replaced if the engine is not delivering the optimum performance, as the direly required spark plug replacement increases the engine efficiency.

Conclusion

In a nutshell the spark plugs and spark plug wires are two decisive things that require proper maintenance and are the backbone of engine efficiency. After certain time intervals these must be replaced to enjoy power of the acceleration on petrol.

Diesel Engine vs Gasoline Engine

Are Diesel Engines Efficient vs Gasoline Engines? The rivalry between the gasoline engines and diesel engines has been there since the birth of both the engines, and the trophy of this competition keeps on changing its winner. This cat and mouse race between both the major types of internal combustion engines does not seem to end, as both the engines have their pros and cons. It now depends upon the user to select the engine as per the use requirements. However, still the factor of efficiency can be termed as a gauge to appreciate one kind of engine over another. The modern times are witnessing now the enhanced efficiency of gasoline engines over the diesel engines.

Highway Usage Edge

When both the gasoline engines and diesel engines are compared with regards to the factor of efficiency at higher speeds, especially for long distance travelling, the efficiency of the diesel engines has always been appreciated over the gasoline engines because at higher speeds higher compression ratios coupled with lean fuel burning due to rich air in the mixture has always given the diesel engines an inherent edge over the gasoline engines.

Future of Gasoline Engine

This inherent edge in diesel engines could not be overcome except for revolutionary introduction of the hybrid fuel gasoline engines. However still as a whole diesel engines enjoy the efficiency edge over the gasoline engines. The modern times though are witnessing the minimization of this edge of diesel engines over gasoline engines and the future of gasoline engines is expected to be much brighter than the diesel engines. It is also due to the stricter emissions regulations which are making diesel engines proving to be less efficient due to the exhaust of diesel engines, and this gap of efficiency between the two engines is expected to close within the current decade.

Newer Technology in Gasoline and Diesel Engines

Newer technology being introduced in the gasoline engines is ever changing at a very fast pace amalgamated with lots of versatility such as variable valve lift timed ignition, gasoline direct injection, multi-port fuel injection systems and introduction of turbochargers have added a lot to the efficiency of gasoline engines. Also affiliated improvements in the electronics and metallurgy have further enhanced the efficiency of gasoline engines. Further research towards lean burn combustion and the innovation in the technology of homogeneous charge compression ignition further decreases the gap between the efficiency of the diesel engines and gasoline engines. Research on shifting of gasoline engines on more energy dense fuels is also underway which can further prove to be a milestone in taking an edge over the more

When to Replace Car Tires with New Tires?

Cars are directly dependent upon tires for their movement as humans are dependent upon shoes for the same. Hence car tires play a crucial role in numerous driving phases, may it be drifting, normal driving, acceleration, deceleration, braking action, aiding suspension and steering response; car tires are the major component which are there playing their role in every movement of the vehicle and bearing all the load and all types of frictions upon them directly. It is therefore very necessary that to buy car tires the tires selection be done with due consideration for achieving a safe and comfortable drive. Now the question of the questions is that how and when to replace the car tires which are worn out, as the tires should be regularly checked for their wear and tear. Some of the best tips to determine whether it's time to buy new tires are mentioned below:

Inspection

Car tires should be inspected on regular intervals may it be weekly or monthly but must be checked. One important aspect about the car tire

inspection is that they do not wear out uniformly and a uniform wear and tear should not be expected when inspecting the tires wear. All the environmentally friendly car tires should be inspected from the inside and outside, for uneven wear and any other cuts or bruises. It is important to note that uneven wear in tires is due to inaccurate wheel alignment, towing or pulling, faulty suspension, driving style and road conditions.

Wear Markers

May it be hard wearing car tires or environmentally friendly car tires, almost all of the good quality car tires are manufactured with wear indicators embossed in between the threads base. Car tires should be regularly checked for the wear in accordance with the wear markers, when tires tread is about to reach the level of the wear marker, replace the tires as after that the car tires are no more road worthy and should not be blamed for any accident. Hence the tires should be replaced when there is around 3 mm of car tire tread is remaining, to be on the safer side.

Life of the Tire

Almost all of the car tire manufacturers claim that the life of car tire is five years from the date of manufacturing. It is also mentioned on the side wall of the tires. The tires should be thus immediately replaced when that date is over, even though if the wear in the car tires may not be that much. As after that the car tires performance is compromised and safety concerns too. The manufacturing date is mentioned as a four digit number in which the first two numbers indicate the week of manufacturing and the second later numbers indicate the year of the car tires. 

This guide explained when car tires should be replaced. Hope you found it helpful.
