Additives for 4 stroke go kart pucks?
go kart additives?? fuel or crankcase??
What is the fuel mixture for a 2004 Honda 50HP 4 stroke?
The 4 stroke Honda outboard is a 4 cycle engine using crankcase oil for lubrication, no fuel / oil mix is required.
In a two-stroke reed valve engine the reed valve is used to seal fuel in the?
In a two-stroke reed valve engine the reed valve is used to seal the fuel air mixture in the crankcase.
Why does a 2 stroke engine need oil mixed in the gas?
Because of the way 2 stroke engines work. On a 4 stroke engine there are intake and exhaust valves in the head, and the crankcase is full of oil. On the intake stroke, the intake valve opens and the fuel-air mixture is sucked down into the cylinder. On a 2 stroke engine they put the fuel-air mixture into the crankcase. On the piston's down stroke, the bottom of the piston compresses the mixture. When the piston goes down far enough to open the inlet, the fuel-air mixture is squirted into the cylinder. If they put motor oil in the crankcase, you'd wind up squirting liquid oil into the cylinder. When the engine tried to "compress" the liquid oil, the incompressible liquid oil would break something.
Doe oil in gas lube the crank and rod on a 2 stroke motorcycle engine?
Correct. A 4 stroke engine has oil contained within the crankcase that is pumped around to all rotating parts. Because the 2 stroke takes its fuel into the crankcase on route to the cylinder, lubrication is added to the fuel to keep the crank lubed. This is the main reason 2 stroke engines are less popular today as the lube oil within the fuel gets burnt. Emission regulations mean it gets tougher to keep the exhaust gases clean enough.
In a two stroke piston port engine the transfer tube is used to transfer fuel from the?
B: from the crankcase to the top of the combustion chamber. good luck on test :->
What is the function of crosshead in 2 stroke engine?
The function of the crosshead is that it absorbs the transverse thrust of the engine. The isolation of the crankcase allows lower cost residual fuels to be burnt without the fear of any fuel contamination of the lubricating oil of the crankcase.
1992 yz250 has gas in the crankcase what's wrong?
Worse case scenario. Float needle stuck in the carb with piston on the intake stroke. Rings may have washed out allowing fuel to pass into the crankcase. You didn't state how much gas though. Your yz uses the oil in the gas to lubricate the crankcase so a little is normal.
What are reeds used for on a 2 stroke motor?
The reeds in a 2 stroke engine perform the same task as intake valves in a 4 stroke engine. The reeds are mounted to a flat plate, or a cage, positioned behind the carburetor(s). On the intake / compression stroke, the reeds are pulled open, exposing the holes milled into the plate, or cage, allowing the fuel charge to be pulled into the engine crankcase from the carburetor. During the power, or exhaust stroke, as the piston moves down the cylinder, the reed valves are forced back against the plate / cage, preventing the fuel charge from being forced back out of the crankcase. This fuel charge is then forced around the crankshaft, (lubricating the rods and bearings), and into intake ports, which are milled into the side of the cylinder wall. As the piston travels back up the cylinder, the intake port is closed off, the exhaust from the previous stroke is expelled, and a fresh fuel charge is drawn into the crankcase via the reed valves. This cycle is repeated over and over, amazing these engines are so durable.
What can cause gas to get into the crankcase on a 97 Pontiac 4-cylinder fuel injected 2.2?
Possible causes of fuel in crankcase are: Leaking injector at shutdown, flooding of the engine due to hard starting, defective fuel pressure regulator. A fuel pressure check for drop of fuel pressure at shut down will verify if an injector is leaking. Get this fixed ASAP, and stop driving the car until you do. Fuel in the crankcase will cause severe engine wear and destroy this engine. Change the oil and filter if you have to drive it anywhere for repair.
Fuel injection crankcase?
thats not a question
What does a roots blower on a 2 stroke diesel engine charge air to?
It is used for scavenging. A 2 stroke needs a way for the exhaust gases to be forced out, which in a 4 stroke, is done on the exhaust stroke. The reason a small 2 stroke has oil mixed into gas, is because fuel is in the crankcase, where the oil should be. This is because scavenging (forcing the exhaust gases out) is done by the pressure created in the crankcase when the piston moves down (at which point fuel is forced out of it and into the cylinder, and the action of this forces the exhaust gases out. This is done by a roots blower in a Detroit Diesel. This is why even turbo charged Detroits have a blower aswell. The blower is forcing the exhaust gases out, which is used to drive the turbo. The blower is essentially driving the turbo.
