All You Need to Know About ATV Four-Stroke Engines
Imagine yourself ripping through picturesque backcountry trails and going on an adventure where no other vehicle dares to go. All-Terrain Vehicles or ATVs provide an adrenaline-pumping and unforgettable experience. It is perfect for riders who are looking for an alternative to cars and motorcycles.
If you are one who owns or is planning to buy an ATV, remember that it needs regular maintenance, which includes parts replacement at some point. One of the most common parts is the 125cc 4 stroke engine reverse function.
Before checking out the shops and purchasing this engine, it would be best to arm yourself with these facts so you can make the best choice possible:
Four Stroke vs. Two Stroke
Automobile technology has come a long way, and all cars, ATVs, and light trucks use a four-stroke piston engine. On the other hand, only weed whackers, chainsaws, snowmobiles, and mopeds use a two-stroke engine because it can provide power for a lighter weight.
A four-stroke engine works when the crankshaft rotates twice, while each piston performs an up and down movement twice as well. This motion produces one pulse of power for each firing of the spark plug.
A two-stroke engine, on the other hand, completes an entire combustion process with only one stroke of the piston. After the compression stroke, the compressed fuel explodes. For every revolution, the spark plug fires only once. Power is produced for every two piston strokes.
The main difference between the two is how quickly the combustion cycle process takes place, depending on the number of times the piston moves up and down for every cycle. Also, a four-stroke engine produces less pollution as compared to the two-stroke engine.
How a Four-Stroke Engine Works
A 125cc 4 stroke engine with reverse goes through the following process:
- As the rider starts the engine, the piston goes down into the bottom of the cylinder then the intake valve opens. Air and fuel then go into the cylinder.
- At the point when the piston reaches the cylinder’s bottom, the intake valve will close. The piston will move up the cylinder, leading to the compression of air and fuel.
- Next, a spark will take place, creating an explosion inside the cylinder. This combustion process will burn off the fuel and air mixture, forcing the piston to the bottom of the cylinder.
- Lastly, the piston will go back up. Then, the exhaust valve will open. Burnt gases will come out through the exhaust.
Why the Four-Stroke Engine is the Best Choice
A four-stroke ATV engine is more efficient because fuel consumption occurs only every four strokes. It is also quieter and does not have the distinct buzzing and high-pitched sound associated with other engines. The four-stroke engine is also more durable since it runs on a lower RPM.
Regularly check your ATV’s coolant, oil, and differential fluid levels. Keeping the fluid levels of your ride at an optimum level prevents the engine from damaging itself. Checking them every time you take the ATV out will save you money and spare you the headache from trying to fix it yourself.
Owning an ATV and taking it through rivers and rough roads is one exhilarating experience. Using the appropriate engine of the highest quality assures you that you will have the best ATV riding experience.
