What causes an engine to run too rich in fuel?
What causes an engine to run too rich in fuel?
If this is faulty and telling the engine control module to add more fuel, even if the air-fuel ratio is good – it may cause a rich fuel mixture. A faulty O2 sensor can cause the engine to run too rich.
When does rpm depend on the throttle opening?
RPM does not really depends on throttle opening per say. When an engine is at constant speed, there is only the friction force going against the engine (from the bearings) and some others to run pumps and such, such that the engine can run. This represents the load at idle.
What happens when the output of the engine is less than the external load?
If the output power of the engine is less than the external load, the engine will decelerate. If the output power of the engine is greater than the external load, the engine will accelerate. RE: What is Engine Load? Thank you for your response, not clear for me still.
How is load related to tractive effort in an engine?
Lower values of load at any speed will simply indicate that power and torque are reduced to that percentage. “Tractive effort” is the linear force produced at the drive wheels. If gear ratio is held constant, “tractive effort” will be proportional to load, but it is not accurate to say that tractive effort = load. RE: What is Engine Load?

What does the load at idle mean on an engine?
This represents the load at idle. If you give enough heat (fuel combusted) to produce enough torque to go against this load, the engine will idle at constant speed. If you give more heat, it will produce extra torque which will be transformed into acceleration of the moving parts (F=ma or T=Iα in rotation).
