Yes, a 4-cycle engine requires oil for proper functioning. Oil lubricates the engine's moving parts and helps to reduce friction and heat, ensuring smooth operation and preventing damage.
Yes, the Calvin cycle does require ATP for its functioning.
4 Cycle engines do not require an oil and gasoline mixture. The 2 cycle engine does require an oil and gasoline mixture. This oil and gasoline mixture for the 2 cycle engine provides critical lubrication for the rotating/moving parts.
Because a 2 Cycle Engine burns the oil in the gas, and in a 4 cycle engine, it sits in the oil pan, and it isn't supposed to burn it at all.
An advantage from the water cycle are that the earth's population doesn't have to produce anymore water than what we allready have because we use the same water. Provides water for our population, animals and plants. Provides fish to eat. Evaporation and infiltration help to remove impurities from water.
The protein life cycle is essential for the functioning of living organisms. Proteins are involved in various biological processes such as cell structure, communication, and regulation. The life cycle of proteins includes synthesis, folding, modification, and degradation. Proper regulation of the protein life cycle is crucial for maintaining cellular functions and overall organism health.
The proper name for the light-independent reaction is the Calvin Cycle. It is also known as the dark reaction or the carbon fixation process because it does not directly require light to occur.
If it is a 2-stroke engine, 2-cycle engine oil is added to the gasoline. If the engine is 4-stroke, regular 30W motor oil is used. To tell if your engine is 2-stroke or 4-stroke, look for a spout where oil is poured into the engine. If there is no spout, then the engine is 2-stroke and 2-cycle oil must be added to the gasoline.
Your question contained no year or model, so the answer will be pretty general. The fuel is going to be regular gasoline. The pre-mix is determined by a number of factors. Is the engine a 2-stroke or a 4-stroke? 4-strokes require no pre-mix. Use only regular motor oil in the crankcase. 2-strokes require 2-cycle oil to be added to the gasoline before it reaches the cylinder(s). Some 2-cycle engines require you to mix the gasoline and 2-cycle oil in a gas can before you pour it into the gas tank. Some have separate tanks; one for gasoline, one for 2-cycle oil. This last type allows the refueler to pour straight gas in any amount into the gas tank and any amount of 2-cycle oil in the oil reservoir -- the engine will mix them together automatically in the proper amount. Check your user manual to see what type of engine you have. If you run a 2-cycle engine without 2-cycle oil, it will destroy the engine.
If it is a 4-cycle engine you definitely need motor oil. If its a 2-cycle engine then the oil is mixed with the gas. If its a reel mower then no oil is needed except for external lubrication. Depending on the engine manufacturer the 4-cycle engines will require either SAE30 or 10w30 motor oil.
Carnot Cycle is an ideal thermodynamic cycle that describes the functioning of a perfect heat engine. In the refrigeration system we need a cooling effect. So, in effect, refrigeration cycle is reverse in process than that of a carnot cycle, and ofcourse not ideal. Air-conditioners also run on the similar cycle as refrigerators.
If your engine does not have an oil reservoir where you need to add and change regularly, and it does not have a dipstick to check for proper oil level, it is very likely to be a 2 cycle engine. You will need to mix Fuel and 2 cycle engine oil. The engine internals gets lubricated thru the fuel / oil mix. If you do not know the proper mix ratio, you can start with a 40:1. My lawn equipment service company even recommends this mix when you have 50:1. It just gives the engine better lubrication with a negligible difference in performance.
The Miller Cycle engine has a very flat torque curve, with maximum torque achieved at 3500 rpm, as compared to Otto Cycle (standard 4-stroke) engines which generally require 4500 rpm or higher. Due to this lower-end torque ability, the Miller Cycle engine is capable of moving much heavier loads at a much lower fuel economy.
