Because you are pumping unburned fuel/air mix into the convertor and it is igniting inside, creating intense heat and the red glow.
On quite a few older 2 stroke jet ski's, water is injected into the exhuast flow to cool the exhaust pipe, and possible turn the pipe. If the moter stops running and you turn the ski over the wrong way this water can enter the cylinders. Once in the cylinders it can damage the pistons and rings. If the ski is running this is not a problem because the exhaust gasses keep the water from entering the cylinders. If the ski is not running there isn't anything to keep the water from entering the cylinders if the ski is rolled the wrong way.
theres a very good chance that the engine has a blown head gasket. what is happening is the water cooling the engine is escaping past the head gasket & into the engine, mixing with the oil making it milky coloured. the water is also escaping into the cylinders, making the steam come from your exhaust, you may also have trouble when turning the engine over, with water building up in the cylinders when cooling down.
White smoke in the exhaust is water leaking into a piston and turning into steam. You have a leak somewhere in your engine. Your engine may overheat because you are low on coolant. You have run it out through your exhaust pipe. Soon your engine will catch fire and burn up, but you will have saved money by not getting it fixed.
I'd be checking the oxygen sensors
it is burning way too rich.
it can if cat converter is plugged up you can check by letting run at idle and keep checking the exhaust to see if it is turning red
the catilatic converters could be stopped up.
CC is cubic centimeters. measured bore x stroke x number of cylinders. a cylinder is the sleeve in which the piston goes up and down, making a boom and eventually turning your tires
Fuel is injected into cylinders. Spark plugs ignite it. Piston goes down turning crankshaft. Repeat.
Basically, it mixes gas and air and pushes into the cylinders to ingnite and cause an explosion pushing the pistons down, and turning the crankshaft.
Can't take the heat? Instead of getting out of the kitchen, try turning on your kitchen exhaust fan. A method of spot ventilation, your kitchen exhaust fan provides an ideal means of removing unwanted heat and humidity from your kitchen work space. Of course, it is important that household exhaust fans such as those found in kitchens and bathrooms are actually designed to remove this unwanted heat and humidity from the home entirely. If your exhaust fan is instead blowing hot and humid air into your attic, it could result in condensation, water damage and the growth of harmful mold.
yes he is getting darker
