Will headers for a 1999 Hyundai accent 1.5L engine fit on a 2002 Hyundai accent 1.6L engine?

No, they will not fit the exhaust port holes are different.


Will adding dual exhaust to your riding lawn mower increase its performance?

Not necessarily, adding duel exhaust will not increase the performance of a mower. It would require the exhaust port to be bigger and require a bigger pipe to be used.


If there is no water in the oil but the engine is hot and the radiator is empty and white steam is coming out of the tailpipe is it possible that the head gasket broke only on 1 side and is not mixing with oil?

It could be a head gasket or a cracked head. Look at the exhaust manifold for each cylinder on the side that has the white smoke, the cylinder that has the leak will cause that port on the manifold to get super hot. One way to quickly identify which port is to spray some cheap black (or color of choice) paint on the exhaust manifold and fill the radiator and start the engine. The paint on the bad cylinder will burn off first.

Why is valve overlap important?

Having the exhaust valve still open when the intake starts to open uses the exhaust "pull" out the exhaust port to help start the intake charge entering the chamber -- before the piston has started down and has generated it's own vacuum. Also, leaving the valves open longer (duration) increased the density of the intake charge and allowed the headers to better scavenge the exhaust gasses out.

How do you tell if a 49cc engines is a 2 stroke or a 4 stroke for a pocket rocket?

It should be a 2 stroke .Ans. 2A 2 stroke engine has a transfer port from the bottom of the cylinder to about half-way up it; it has no valves.A 4 stroke engine has no transfer port, but has inlet and exhaust valves, with their associated valve gear.


What allows burned gasses to leave the cylinders through tubelike chambers into the exhaust pipe?

It depends whether you are talking about a 2-stroke or 4-stroke engine. A 2-stroke is typically rotary valved where a port opens near bottom dead center of the piston stroke. This port is often in the cylinder wall and this is where the exhaust exits and where the new air/fuel mixture enters. A 4-Stroke has a camshaft that operates intake and exhaust valves. after the combustion stroke of the piston the cam actuates the exhaust valve. As the valve is open the piston comes up pushing the exhaust gas into the exhaust manifold, sometimes called a header or header pipe.

In a 2 stroke engine what carries the valves?

The standard, simple type of two-stroke gasoline engine does not have valves in the sense that a four-stroke engine has them. The two-stroke principle remains the same but they may be achieved by various mechanical means. A main problem with simple two-stroke engines is that they are not very effective in getting rid of the burnt exhaust gases. The difference between models is in how the combustible gas is introduced and also on scavenging or exchanging the exhaust gas for a fresh blend of gasoline and air, finally there are different exhaust methods. The piston-port method is the simplest in small engines, but there are other designs such as the reed and inlet rotary valve, the stepped piston engine, the power valve system and direct injection.


Can i swap dual port exhaust manifolds on a single port ej22 98 impreza engine?

It's not possible.


What is the purpose of exhaust system brakes?

They provide resistance to the engine crankshaft in order to help control speed on a downhill descent. Exhaust brakes and Jake brakes aren't one in the same... an exhaust brake restricts exhaust flow, while a Jake brake opens the exhaust port of the cylinder during the power stroke.

Why in two stroke engine at the place of valve there is port?

What does a expansion chamber do for a dirt bike?

it is used to increase the horsepower of the engine (see this page for a photo). This technique only works on two-stroke engines, which is why you see it on a lot of dirt bikes but not on street bikes. Most street bikes use four-stroke engines.The basic idea behind an expansion chamber is to use the momentum and pressure of the exhaust gases to create a pumpthat squeezes more air and fuel into the cylinder during the intake stroke. It does the same sort of thing that a turbocharger does, but it does it without moving parts.If you have read How Two-stroke Engines Work, then you know that the exhaust and intake parts of the cycle overlap. As the piston moves down, it uncovers the exhaust port first to let most of the exhaust out. Then it opens the intake port to let fuel/oil/air in. With a correctly-tuned expansion chamber in place, two things happen to help the intake process:As the exhaust gases expand into the expansion chamber, they create a vacuum at the exhaust port. This vacuum pulls fuel/oil/air into the cylinder.As the shock wave of the exhaust pulse hits the end of the expansion chamber, it echoes back, pushing any fuel/oil/air that got pulled through the exhaust port back into the cylinder. This page has a nice graphic that describes the process.By pulling extra fuel/oil/air through the cylinder and then pushing it back in, the expansion port has the effect of stuffing more fuel/oil/air into the cylinder on each stroke. This gives the engine extra power in the same way that a turbocharger does.Here are some interesting links:How Two-stroke Engines WorkHow Turbochargers WorkBuilding your own racing Expansion ChambersExhaust Pipe "Theory"Tuned Pipes
