Why is my Honda engine smoking?
If there is a problem within the engine that produces smoke, that smoke will exit the engine through the exhaust. A leaking valve cover gasket might produce smoke caused by oil dripping on a hot manifold. If the leak is large enough, you will likely see the oil dripping on your driveway or garage floor.
What kind of smoke is coming from an engine?
When the engine has cooled, check the coolant tank and radiator hose lines for signs of leaks. The engine emits different types of exhaust smoke – white, black, gray, and blue. For an accurate diagnosis, you must identify each one.
Why does my ATV have black smoke coming from the exhaust?
Black exhaust smoke from your ATV usually means your engine gets more fuel than it can ignite. Blue smoke, on the other hand, occurs when unwanted oil is mixing with the air and gas that goes into your engine for combustion.
What causes white smoke in the engine bay?
Normal causes for white smoke in the engine bay. During cooler days it is normal to see some white smoke coming from the engine. Internal combustion engines operate through the ignition of the air/fuel mixture and produce carbon dioxide and water as byproducts. Little smoke is to be expected due to the condensation of water from the exhaust gases.
Why does my two stroke engine smoke so much?
When warm, on the other hand, a properly jetted two-stroke engine should not smoke much. If it does, it’s probably running a bit rich and needs adjustments made to the carburetor. If your exhaust smoke on your four-stroke is blue-looking, this is likely because unwanted oil contaminates the air/fuel mixture.
How does the Honda VTEC engine system work?
The process of opening and closing the valves that we just described works well at low revolutions per minute (rpm), but the valves open and close so quickly as the engine builds up speed that performance ultimately starts suffering. Honda’s Australian division published the video below to explain how its VTEC technology works.
What does it mean when your car engine is smoking?
The oil will then be combusting together with the fuel and air, creating blue-looking smoke. If the engine is burning oil, you should notice a decrease in the oil levels over time, and you may need to top off with new oil from time to time.
Black exhaust smoke from your ATV usually means your engine gets more fuel than it can ignite. Blue smoke, on the other hand, occurs when unwanted oil is mixing with the air and gas that goes into your engine for combustion.
Why do I get blue smoke when I start my car?
First, you need to determine that the oil is coming from below the engine and not the valves. Blue smoke, when running the engine hard, is caused from a blow by the piston rings due to high pressure building up in the crankcase. Blue smoke at idle or cold start is most likely valve related.
