What does it mean when an engine runs lean?
The goal of a carburetor is to mix just the right amount of gasoline with air so that the engine runs properly. If there is not enough fuel mixed with the air, the engine "runs lean" and either will not run or potentially damages the engine.
What happens when your oxygen sensor is not working?
If your oxygen sensor stops working the fuel (gasoline) and air mixture will be incorrect. Usually this means your fuel efficiency will decrease -- that is, the engine will burn more gasoline than necessary. It's possible however, if it begins to run too lean (not enough gasoline for the amount of air) it can damage the engine. But, this is unlikely.
What is intake stroke in a diesel engine?
In a gasoline engine, it is a fuel-air mixture that is drawn in during the intake stroke, unless the engine is fuel injected. In a fuel injected or a diesel engine, it is air, because the fuel (gasoline or diesel) is injected at the "last moment" before ignition.
Can diesel oil be used in a petrol engine under a lean air fuel mixture?
No. Diesel must be compressed quite a bit more than gasoline to achieve combustion.
What is a lean burn system?
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.
What does it mean if the spark plug is dry and white?
Dry is good, but white is bad! It means that the engine is running lean, which will result in the engine running too hot and can cause serious engine damage (even seizure). Below is a guide to reading the spark plug color. Black = Rich. The fuel/air mixture is too rich (too much fuel, not enough air). Tan/Brown = Normal. The fuel/air mixture is correct. White = Lean. The fuel/air mixture is too lean (too much air, not enough fuel).
What does mean lean mixture or rich mixture?
The ideal fuel/air mixture or ratio for most internal combustion gasoline engines is 14.7 to 1. Meaning 14.7 parts air to one part gasoline. Any ratio below this is considered a rich mixture or too much fuel. Any ratio above this is considered a lean mixture or too much air.
Your 2000 ford windstar check engine light is on and the code reads running too lean - what does that mean?
Running lean basically means that your Air Fuel Ratio is off and there is more air than fuel, which creates a lean condition. It is called the "Stoichiometric" value. The correct ratio is 14.7 parts air to one part fuel. If you are running for instance a ratio of 16 to 1 then that is lean. Basically too much air when compared to optimal air fuel mix. A ratio of 12 to 1 is too rich. The problem with a lean condition is that the engine will run hot. Normal logic would suggest that with less fuel there would be less heat generated, but it is not the case. A lean condition will actually make the engine run hotter.
Can a petrol engine run on lean air-fuel ratio such as 30 by 1 while a diesel engine can?
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.
In case of si engine to have best thermal efficiency the fuel air mixture ratio should be what?
LEAN
In a gasoline engine the area the cylinder head where the air -and - fuel mixture is burned is called the?
Combustion chamber
What do you do before starting an inboard gasoline engine?
Unscrew the fuel air valve on the fuel tank, connect the fuel pipe to the engine and prime the engine with fuel.
