Want this question answered?
4 cycle means that you do not mix oil with the gas. They will have a place for the oil and a place for the gas seperate. Although, not many weedwackers have 4 cycle engines... 2 cycle engines are the ones that you need to mix oil with the gas.
4 cycle oil also known as 4 stroke oil. Reason: 4 cycle oil is not meant to be mixed with gasoline as the weedwacker has 2 separate lines for fuel and lubricant. Conversely 2 cycle weed wackers require 2 cycle engine oil to be mixed at a ratio of 40:1 with the gasoline.
You will need 2 wrenches turning in opposite directions on the retaining nut - its not vey complicated.
Intake,compression,combustion,exhaust.
A 2 cycle engine's piston cycle twice. One compression stroke and 1 exhaust stroke. A 4 cycle engine cycles four times before its exhaust stroke.
The 4 strokes of an internal combustion engine are as follows:- 1 Induction stroke 2 Compression stroke 3 Power stroke 4 Exhaust stoke
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
The four strokes refer to intake, compression, combustion and exhaust strokes that occur during two crankshaft rotations per working cycle of Otto Cycle.
A 4 stroke engine takes 4 strokes to complete a cycle. 1, intake. 2, compression. 3, ignition/power. 4, exhaust.
Suction stroke, compression stroke, power stroke & exhaust stroke
4 cycles consist of: Intake cycle Compression cycle Ignition cycle Exhaust cycle Intake cycle - piston in lowest position intake valve open allown atomized fuel to enter combustion chamber Compression cycle - piston in upward stroke compressing atomized fuel mixture All valves closed Ignition cycle- Spark is introduced to combustion chambeer blowing piston back down in chamber valves closed Exhaust cycle- exhaust valve open piston rises in chamber to expel spent gasses.
The 4-stroke cycle does not start with the compression stroke. it goes -1. Intake2. compression3. power4. exhaust
