Lean burn engines operate with a fuel-air mixture that has a higher proportion of air than is typically needed for complete combustion, resulting in better fuel efficiency and lower emissions of certain pollutants. In contrast, rich burn engines use a fuel-air mixture that is richer in fuel, which can enhance power output but often leads to higher emissions of unburned hydrocarbons and nitrogen oxides. The choice between the two depends on the desired balance between performance, efficiency, and environmental impact.

No, the perfect fuel/air ratio is 14.6 to 1. A ratio of 13 to 1 is a safe ratio for most non turbo gas engines. Turbo engines can run a 12 to 1 ratio. Chrysler's lean burn system of the 70's and 80's used a ratio of around 18 to 1 and it was horrible. No gasoline engine can run at 30 to 1.
Mass concrete is concrete cast without Rebars. They are good in compression and are mostly used for the construction of gravity structures such as Dams. While reinforced concrete have reinforcement bars in them, which increases the tensile strenght of the concrete.

Depends on the fuel. Type of engine is not important. For gasoline, a 16:1 ratio would be ideal, for alcohol (Ethanol) 8:1 is considered ideal. A good estimate for any fuel is to split the difference between Lower Explosive Limit (won't burn; too lean) and Upper Explosive Limit (won't burn, too rich). For example, Propane has a LEL of 24,000 ppm, and HEL of 96,000 ppm, so split the difference and 60,000 ppm should burn pretty well. 60,000 ppm should be about 6% or 17:1.
Lean burn refers to operating a gas turbine with excess air to optimize fuel efficiency and reduce emissions, while rich burn involves adding more fuel to the combustion process to increase power output. Lean burn technology is typically used for low emissions and increased efficiency, while rich burn is used for higher power output and faster response times.

Rich is more face to face communications. Lean is e-mail. The less you interact with the audience the more lean you are.
A vacuum leak can cause a lean burn.
Lean Pockets are healthier than Hot Pockets and come in more varities. They are both produced by Nestle
Not necessarily. The position during a kiss can vary based on personal preference, comfort, height difference, and the dynamics between the individuals involved. Some may naturally lean to one side, while others may not.
A lean too is a supported structure, usually built between two trees with an open side and an closed slanted cover.A wickiup is a free standing domed shaped hut or tent.
The difference between lean and lien in terms of property ownership and financial obligations is that a lean refers to a claim against a property for unpaid debts or services, while a lien is a legal right to keep possession of property until a debt is paid off. Essentially, a lean is a type of lien that specifically relates to property ownership and financial obligations.
Lean muscle is dense.
A lean burn system is a fuel burning system that uses an excess of air in an internal combustion engine. They provide a high air to fuel ratio and are used in some vehicles.
The difference is mainly in the texture. For example, breads made with lean dough tend to be chewier and have more bite than those made from rich dough. Rich dough is also commonly referred to as enriched dough.
