A conventional diesel engine will smoke excessively under load in situations whereby the engine rpm are too low for the throttle position ie, your throttle is opened too far and the revs are too low for the load the engine is expected to move- This is sometimes called "overfuelling". It basically means there is too much diesel being injected in relation to too little air being induced into the engine, in the same way that when you pour too much charcoal onto your barbeque fire it smokes because you are smothering it and there is not enough air. The amount of air that is induced into your engine is proportional to the engine rpm on most diesels like old landrovers, so don't change gear too early, or lug your engine. You will notice if you look in your side rearview mirror that when you go up a steep hill it may smoke excessively if you step on the gas pedal too much, but you will also notice that beyond a point you will get no corresponding increase in power, in other words you are just pouring fuel into the engine which is not even being burnt properly, and you are just wasting fuel and carboning up your engine. Some modern diesels overcome this problem by electronics. The gas pedal position is measured in conjunction with the air intake pressure and engine rpm and if you floor the pedal with the revs being too low, the computer will to some extent override your decision to prevent wasteful and incomplete burning of fuel.- This "drive by wire" system has its dissadvantages, imagine if a rat eats your wiring loom or there is a bad connection, you could have no throttle. the conventional system is better if you monitor the amount of overfuelling as you drive and tap off a bit when the smoke gets excessive.
Yes, if the the engine is a steam engine or a diesel engine. The diesel engine smoke should be almost invisible when the engine is in good condition. Electric locomotives are not typically called "engines", but these do not produce smoke.
In a diesel engine, blue smoke is an indication of oil being burned. Black smoke means that there is incomplete combustion of the fuel. White smoke can be seen when raw diesel fuel is not being burned.
Actually, it depends on the engine. I have a car here in the Philippines which is run by Diesel but there is no smoke. Meaning, my engine is in a good state! my blog - http://www.rickspot.com
Hi there,blue smoke on a diesel motor is normally fuel,and the smell will be unburn diesel,rough start and heavy smoke that will disapear as the engine getshot.
You can drive a diesel engine, or any other type, blowing any colour smoke you wish. Though it is pretty foolish to smoke
Blue smoke is burning oil.
The black smoke that a diesel engine blows out is fuel that is unburned. The black smoke can be caused from over-fueling, poor fuel quality, or dirty or worn fuel injectors.
changed engine
Yes, it will smoke and will not run correctly, if at all. Diesel fuel will not explode and instead produce smoke. It can also clog your fuel injection. If diesel is added to a gasoline tank, the fuel should be removed. If there is too much diesel mixed in, the engine will likely not run at all.
Blue smoke is caused by engine oil being burnt by the 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.
Turn the fuel down.
