NO that's bad
Hey Roger===If you stated the kind of car and engine you had it would be easier. Just guessing, it is either the cable to the throtle body or carb hanging or the idle solonoid needing cleaning. GoodluckJoe A sizable vacuum leak could also do that.
Yes, it is normal
It does not mix under normal conditions. If this is happening with your diesel engine you may have engine trouble.
There is no such engine as a Cummins 2500 Diesel.
It will depend upon the conditions. Under normal operating conditions a diesel engine is more efficient than a petrol engine.
White smoke at start up is due to moisture in the exhaust or on a diesel it can be normal due to the engine being cold.White smoke at start up is due to moisture in the exhaust or on a diesel it can be normal due to the engine being cold.
The normal engine operating temperature, for a 3306 Caterpillar diesel engine, is 180 degrees. The engine should not be operated at temperatures above 200 degrees.
It has a compression ratio of 17.5:1
180-210
Yes it can. Biodiesel can be used in any diesel engine, but it isn't usually used for tractors because it has a lesser energy yield than normal diesel.
If the engine is diesel, no that is normal. If the engine is gasoline, yes it is probably burning oil.
The engine is a 2 stroke 'semi' diesel. Inlet and exhaust are as per 'normal' two stroke diesel but the injected fuel is not ignited by compression alone as in a normal diesel. Instead a 'hot bulb' on the cylinder head is heated with a blow-lamp before starting and heat from this, transferred to a tube in the combustion chamber which ignites the fuel to start the engine. Once running the engine itself maintains the temperature. Often called a Hot Bulb Engine.
