A four-stroke cycle engine is an internal combustion engine that utilizes four distinct piston strokes (intake, compression, power, and exhaust) to complete one operating cycle. The piston make two complete passes in the cylinder to complete one operating cycle.

Otto cycle is used by petrol ignition whereas diesel engine uses the diesel cycle. Another noteworthy difference is that the Otto cycle heat occurs at constant volume, whereas the diesel cycle works on constant pressure. This could be the main difference between Otto cycle and diesel cycle.

Explanation: Otto cycle is more efficient than Diesel cycle for a given compression ratio. 6. For constant maximum pressure and heat input, the air standard efficiency of the gas power cycle is in the order.

Diesel combustion. The diesel engine is an intermittent-combustion piston-cylinder device. It operates on either a two-stroke or four-stroke cycle (see figure); however, unlike the spark-ignition gasoline engine, the diesel engine induces only air into the combustion chamber on its intake stroke.

Two-stroke engine bikes are lighter and faster bikes that have an intense kick to the motor. This makes it easier to throw around your bike with the faster punch per cc. Two-strokes also require more frequent shifting, but riders can get a faster top speed with more power.

A two-stroke diesel engine is a Diesel engine that works by combining what is normally four cycles – intake, compression, combustion, and exhaust into only two strokes (one revolution) of the engine. It was invented by Hugo Güldner in 1899.

Answer: Two-strokes left the market because they could not meet steadily-tightening EPA standards for vehicle exhaust emissions. A four-stroke engine has a separate piston stroke for each of the four functions necessary to a spark-ignition engine: intake, compression, power, and exhaust.

Honda’s secret plans: Two Strokes are BACK! Honda is planning to bring back two-strokes with a clean-burning, fuel-injected, all-new screamer engine. Patents have just been published that show the side and front elevation of a new two-stroke engine from the big H.

Direct injection two-stroke engines, made since 1999, are considered clean emission engines and can be used on every water body in California, with some exceptions not related to emission limits.

A stroke is a motion of a piston, meaning a two-stroke dirt bike has 2 different motions of the piston, while a four-stroke has 4. 2 Strokes are generally more unstable and accelerate faster, while a 4 stroke is more consistent and has a higher top speed.

Typically, a 2-stroke engine creates more torque at a higher RPM, while a 4-stroke engine creates a higher torque at a lower RPM. Because 2-stroke engines are designed to run at a higher RPM, they also tend to wear out faster; a 4-stroke engine is generally more durable.

I would suggest a 4 stroke to start. Most 2 strokes are a lot more work to maintain. They do make more power but they require much more maintenance than a 4 stroke. Basically a 4 stroke just lets you focus on learning to ride instead of a bunch of other stuff.

While a 2-stroke will never offer the torque of a 4-stroke, they come close enough for most weekend riders. Not only that, but they’re lighter and tend to be easier to handle, which makes them great for beginners. Older 2-strokes require riders to rev the engine to make any power.

When properly set up, 2 strokes are great trail bikes. As far as maintenance goes, they require less than most new 4 strokes, but more than older, less high-strung dirt bikes such as XRs. They do need the gear oil changed, and the topend done once in a while.

Because combustion takes place with each revolution of the crankshaft with a 2-stroke, this format puts out more power than a 4-stroke engine and the power has more instantaneous delivery.

What is 2 stroke fuel? Two stroke fuel is basically unleaded petrol mixed with 2 stroke oil. The oil to fuel mix ratio should be specified in your engines instruction manual. The oil in 2 stroke fuel is extremely important in lubricating your engine as two stroke engines do not have an internal oil reservoir.

Use a 32:1 gasoline to oil ratio. One gallon of gasoline combined with 4 oz of two-cycle engine oil.

Two- stroke oil will last for a couple of years when it is not mixed with petroleum. Once mixed with petroleum we would not recommend keeping for more than 3-4 months in a sealed air tight approved storage container.

Yes, 2 cycle oil can go bad. If sealed, two-stroke oil usually good for up to 5 years. If opened, the shelf life is reduced to 2 years. Once mixed with gas the fuel should be used within two months.

Two stroke engines are usually low compression engines — often around 7 or 8:1, so they run just fine on lower octane fuel. You CAN use high octane, but it’s not necessary. Unlike oils designed for four stroke engines, there are VERY few additives in two stroke oil as it is designed to burn as cleanly as possible.

Using a 4-stroke oil in a 2-stroke engine can therefore disrupt combustion and cause smoke formation and engine degradation.
