what is the difference between 4 cylinder engine and 4 cycle engine?

Question

as i know, 4 cylinder engine with 1.8Liter, so the total capacity combustion room of mix fuel and air is 7.2Liter, so how about 4 cycle, is it possilbe with 4 cylinder along with 2 cycle engine?

Answer 1

4 cylinder engine has 4 pistons a 4 cycle engine fires once for every 4 revolutions of the crank shaft

and yes there are 4 cylinder 2 cycle motorcycle engines and some diesels

google 4 cycle and 2 cycle look for the how stuff works
you havent a clue what your talking about a 1.8liter is the capacity in a 1.8 motor not 7.2

Answer 2

If by ' cycle' you mean 'stroke'.. as in 2 stroke and 4 stroke.

In a four stroke engine, every time the piston goes up and down, it does something, like suck in gas through the open inlet valve. Next time it goes up it compresses the gas and ignites it sending the piston round again to force the gasses out of the exhaust valve and so on and on.
This type of engine is a four stroke engine because the complete cycle consists of 4 operations or cycles.


In a two stroke, the complete cycle is done in only 2 strokes of the piston because it is a different design and does not have conventional valves which open and shut. 2 stroke fuel is a mixture of petrol and oil. Two stroke engines tend to be higher revving, more smokey and have a distinctive sound like a mosquito with a hot poker up its bum.
Whether 2 or 4 stroke, the piston runs in a cyclinder. So one piston in the engine is a single cyclinder engine, 2 cyclinders is a twin, 3 cylinders is a triple, four can be a four in line or a Vee four and so on. Then there is aircraft Radial engines where the pistons are arranged geometrically round a central hub or shaft. Then there is the Wankel or rotary engine, but that is a different animal.

Cylinders can also have different orientations. A BMW 'Airhead' is a four stroke horizontally opposed twin. ( known as the Boxer engine)
Most Harleys are a four stroke Vee twin.
Many bikes are four or two stroke singles.
Triumph make a nice Triple.
An old European Car maker called DKW once had a car with a three cylinder , two stroke engine.
Many model aircraft are powered with little minature deisel or 'glowplug' engines which are basically two stroke.

Combustion capacity is measured in cubic centimetres (cc) or Litres. If therefore, a four cyclinder engine had 500cc combustion capacity in each cyclinder, the total capacity of that engine is 2000cc ( or2 litre)

By some strange convention, we tend to refer to car and boat engines in terms of Litres and bike engines in terms of cc.
A 1200cc BMW bike has the same capacity as a little 1.2 liter compact car.

Thats about it buddy.

Answer 3

Each cylinder on a 4 cylinder engine has a 4 cycle process..
1)Intake
2)compression
3)power
4)exhaust
The cycle begins at top dead center (TDC), when the piston is furthest away from the crankshaft. On the first stroke (intake) of the piston, a mixture of fuel and air is drawn into the cylinder through the intake (inlet) port. The intake (inlet) valve (or valves) then close(s) and the following stroke (compression) compresses the fuel-air mixture.


Four-stroke cycle (or Otto cycle)The air-fuel mixture is then ignited, usually by a spark plug for a gasoline or Otto cycle engine or by the heat and pressure of compression for a Diesel cycle or compression ignition engine, at approximately the top of the compression stroke. The resulting expansion of burning gases pushes the piston downward for the third stroke (power) and in the fourth stroke (exhaust) the piston pushes the products of combustion from the cylinder through an exhaust valve or valves.

Answer 4

You've got the first bit wrong. If it's a four cylinder with 1.8 litres you'd have 0.45 litres in each cylinder giving a total of 1.8 litres.
Also further to the above answer, it is possible to have a four cylinder 2 cycle or 2 stroke engine. Yamaha's RZV500R was a 500cc 4 cylinder 2 stroke engine which went like the clappers.

Answer 5

a 2cycle engine has oil an fuel mixture where a 4 cycle engine just uses no mixture of fuels
the 2 cycle is also known as a 2 stroke in simple terms the 2 stroke the piston moves up an down doing the same thing as a 4 stroke takes 4 moves up an down this is why the 2 stroke is faster than a 4 stroke but mixing gas an oil in ratios can be a real pain

2 cycle oils are usually around a 20 wieght...., are made to be burned.... and not to burn so easily (to leave oil in the crankcase.... lube the piston and rings/bore while providing metal to metal protection) 4 cycle oils are usually a 30 weight..... (5w-30 is a example) and are not formulated to burn..... and has antiwear additives to prevent wear, and detergents to keep the engine clean.... never use a 2 cycle oil in the crankcase of a 4 cycle (may in a light mix, in the gas though, great upper cylinder lube) and never a 4 cycle oil in the gas of a 2 cycle.... it'll smoke like heck... and not provide the high heat and rpm protection leading to a early worn out engine.

Answer 7

Cylinders is the number of round holes, with pistons, in an engine block. 1.8 is the volume of all four cylinder holes, when the pistions are at their lowest point.

Four cycle describes the way an engine operates. First cycle is intake of fuel, second is compression, third is expansion and the fourth is exhaust.

You can have a four cycle enging with any number of cylinders. My lawn mower has one cylinder, with one piston, and is a four cycle engine.

Answer 8

I doubt if you can find a 4 cylinder with a 2 cycle regime. Basically, four cylinders mean you've got for pistons doing their own up and down movements to keep you going. The four major stages of these movements are the intake, compression, combustion and exhaust. This is what can be termed cycles. So in every cylinder, you've a piston doing all four stages. In a two cycle, intake and compression are combined and combustion and exhaust are combined as well.
