[30] [31] Project 2025 does not explicitly promote the prohibition of abortion, [116] but some legal experts and abortion rights advocates said adopting the Project's plan would cut off access to medical equipment used in surgical abortions to create a de facto national abortion ban. [215] [216]
The oil is dyed blue to make it easier to recognize in the gasoline. It appears black in this bottle because it is not diluted. Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a special type of motor oil intended for use in crankcase compression two-stroke engines, typical of small gasoline-powered ...
The engines operates on the 2-stroke cycle principle, are air started, and are rated at 1600 bhp at 756 rpm on the 16-248 and 750 rpm on the 16-278A. The size of the bore and stroke of the 16-248 engine is 8 + 1 ⁄ 2 inches and 10 + 1 ⁄ 2 inches respectively as compared to 8 + 3 ⁄ 4 inches and 10 + 1 ⁄ 2 inches for Model 16-278A.
Grades may appear alone - for example, a lawnmower may require SAE 30. This single grade specification means that the oil must meet the SAE 30 requirements. But SAE also allows designating an oil with two viscosity grades, referred to as a multi-grade oil. For example, 10W-30 designates a common multi-grade oil. A 10W-30 oil must pass the SAE ...
Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines can also have fewer moving parts, and thus be cheaper to manufacture and weigh less. In countries and regions with stringent emissions regulation, two-stroke engines have been phased out in ...
The International Lubricant Standardization and Approval Committee (ILSAC) also has standards for motor oil. Introduced in 2004, GF-4 [27] applies to SAE 0W-20, 5W-20, 0W-30, 5W-30, and 10W-30 viscosity grade oils. In general, ILSAC works with API in creating the newest gasoline oil specification, with ILSAC adding an extra requirement of fuel ...

The gas-generator cycle, also called open cycle, is one of the most commonly used power cycles in bipropellant liquid rocket engines. Propellant is burned in a gas generator (or "preburner") and the resulting hot gas is used to power the propellant pumps before being exhausted overboard and lost.
