A governor in an engine is designed to regulate the speed. It does so by automatically adjusting the fuel supply whenever the speed exceeds or drops below the desired level. This ensures that the engine operates within its specified RPM (Revolutions per Minute) range, preventing potential damage caused by excessively high or low engine speeds.
1. Cost: Nitrogen is more expensive than normal air, which adds an extra cost every time your tyres need inflating.
2. Accessibility: Nitrogen is not as readily available as air. You cannot just go to any garage or petrol station to inflate your tyres with nitrogen. You would have to go to a specialised centre, which could be inconvenient.
3. Time-consuming: As it's not commonly available as normal air, you may end up spending more time searching and traveling to get nitrogen for your tyre.
4. False sense of security: some vehicle owners may believe that they don't need to check tyre pressure just because they are using nitrogen instead of regular air. Nitrogen filled tyres can also lose pressure, which can decrease fuel efficiency and safety.
5. Not environmental friendly: The production and transportation of nitrogen gas could potentially have a negative impact on the environment, compared to just using normal air.
6. Need for purity: To get the full benefits of nitrogen, you need to have a high level of purity in the tyre. This can be difficult to achieve and maintain, as most places can only offer about a 95% level of purity, not the 100% that is needed.
Nitrogen. while pricier than regular air. requires an extra fee to fill your tires. This can make it difficult to locate since it is not readily available at all gas stations. Despite its higher cost. there is no significant improvement in fuel economy when using nitrogen in tires. While some believe that nitrogen filling promotes longer tire life. the difference is usually minimal. Additionally. even with nitrogen-filled tires. it is still necessary to regularly check the pressure as they naturally lose it over time. In situations where replenishing with nitrogen is not feasible. regular air must be used to dilute the concentration in the tires. It should be noted that some may mistakenly assume that nitrogen-filled tires do not require routine maintenance and have a false sense of security; however. this is not the case.
The IC engine operates by converting chemical energy from fuel into mechanical energy. It follows a multi-step operating cycle. including intake. compression. combustion or power. and exhaust strokes. The intake stroke involves the piston moving downward to decrease pressure in the cylinder. allowing for the entry of the fuel-air mixture through the intake valve. In the compression stroke. both valves close as the piston moves upward. compressing and heating the mixture for ignition. The spark plug then ignites the compressed mixture. causing it to rapidly expand and generating power for the crankshaft. During the exhaust stroke. the piston moves upward again to open the exhaust valve and release exhaust gases. This is followed by closing of the exhaust valve. opening of the intake valve. and repetition of these four strokes to produce enough force for vehicle movement.
