The 4 cycles represent the strokes that the piston makes as it travels up and down the engine cylinder. Generally considered to be the first cycle (stroke) is the downward stroke commonly referred to as the intake stroke because during that stroke it pulls a mixture of air and fuel into the cylinder.
The following (2nd) stroke is called the compression stroke because it compresses the air and fuel mixture as the piston travels upward.
As the piston approaches the top of it's travel on the compression stroke, the spark plug (in gasoline fired engine) is energized by an electrical charge causing a spark to jump across the 'gap' of the spark plug. This spark ignites the fuel and air mixture. The resultant 'explosion' then drives the piston downward on the 3rd stroke which is called the power stroke.
When the piston reaches the lowest point of its downward travel, the exhaust valve opens and the movement of the piston upward on its 4th cycle (aka Exhaust stroke) pushes the burnt gas mixture out of the cylinder into the exhaust system and the 4 cycles begin all over again.
Because the bottom of the piston is attached to the crank shaft it causes the crank shaft to rotate. This rotation is transmitted to whatever mechanical need the engine is to supply. On a car, it turns the wheels. On a lawn mower it turns the cutting blade.
Only if it is a 2 cycle engine and you mix the oil with the gasoline. If it is a 4 cycle engine, then using 2 cycle oil will destroy the engine over time. Use SAE 10w30 synthetic oil in your air cooled 4 cycle engine.
A car engine is a four cycle internal combustion engine, there are four cycles. 1. inlet cycle 2. compression cycle 3. ignition cycle 4. exhaust cycle hope this helps
Absolutely not. Use only 4 cycle oil in a 4 stroke engine. 2 stroke oil is formulated to be mixed with gasoline and will not protect a 4 cycle engine.
If the engine has an oil sump and an oil filler spout, it is a 4-cycle engine. On a 2-cycle engine, oil must be added to the fuel.
'a 4 stroke engine cycle' is usually what it is called...
Absolutely not. Use only 4 cycle oil in a 4 stroke engine. 2 stroke oil is formulated to be mixed with gasoline and will not protect a 4 cycle engine.
4-cycle
Because a 2 Cycle Engine burns the oil in the gas, and in a 4 cycle engine, it sits in the oil pan, and it isn't supposed to burn it at all.
You can not use 4-cycle oil in a 2-cycle engine because the four cycle oil will not mix it is not designed to.Two cycle oil is designed to mix with fule to lube the two cycle parts in your motor.
Use 4 cycle oil if the engine is a 4 cycle engine. Use 2 cycle if it is a 2 cycle. Use the weight oil recommended by the manufacture of your ATV.
4-stroke
Look at the engine on your lawn mower. If the engine has an oil filler tube or a "hole" with a cap on it where oil is added to the engine, it is a 4-cycle (4-stroke) engine. If there is no oil filler tube or place to add oil to the engine, then it is a 2-cycle (2-stroke) engine and the oil has to be added to the fuel.
