Yes, you can put air in nitrogen-filled tires without causing any harm. Nitrogen is used in tires because it's less likely to seep through the tire walls than oxygen, offering more consistent tire pressure over time and slightly better fuel efficiency. However, in everyday use, especially for passenger vehicles, the benefits are minimal. If your tires are low and you only have access to regular compressed air, it's perfectly okay to top them up. The mixture of nitrogen and oxygen won't cause any issues. It’s more important to maintain proper tire pressure for safety and performance than to worry about the type of gas inside.
While it is possible to inject air into a tire already filled with nitrogen. doing so will decrease the effectiveness of nitrogen-filled tires. Typically containing 78% nitrogen. 21% oxygen. and 1% other gases. regular air is not as ideal for tire use due to its tendency to pass through rubber more easily. This can result in less stable tire pressure over time. If you opt for nitrogen-filled tires and need to refill them. experts advise sticking with nitrogen whenever possible.
Starting an inboard boat engine out of water requires a process to avoid damage. It's crucial to supply water to the engine to prevent overheating since water typically cools the engine during operation. One common method is to use "fake-a-lake," a plunger-like tool that attaches to the boat's hull and connects to a garden hose to supply water to the cooling system. Alternatively, if your boat is on a trailer, you can position a garden hose directly to the water intake or use muffs over the water intake ports, also connected to a hose. Ensure the water is running before you start the engine. Monitor the water flow to avoid overheating, and limit the time running the engine to only as necessary for diagnostics or testing.
When preparing to start internal combustion engines in water. also known as dry starting. it is important to avoid causing harm to the engine impellers. This is especially crucial for raw water pumps that rely on water for lubrication and cooling purposes. To safely begin a marine engine without using water. a flushing sleeve or dummy rake is necessary. These tools are designed specifically to supply water directly into the engine's cooling system. Here's how it works:
The weight of an LS engine largely depends on the specific model and its components, such as whether it's aluminum or iron-block. Generally, an LS engine can weigh between 400 to 600 pounds (181 to 272 kg). Aluminum block versions, like the LS1 or LS3, are on the lighter end, approximately 415 pounds (188 kg) when fully dressed with accessories. Iron block variants, such as the LQ4 or LQ9, tend to be heavier, nearing the 600-pound mark (272 kg) fully equipped. These weights include the engine accessories like the alternator, starter, and water pump, which are necessary for the function of the engine. Your specific application and choice between aluminum and iron will greatly affect the engine's weight, hence impacting your decision based on performance needs and vehicle weight distribution.
LS engines range in weight from 400 to 600 pounds. depending on the type and modifications. Most stock LS engines weigh between 460 and 490 pounds.
