Least number of valves required at the top of a four-stroke cycle engine?
Two. Intake, and exhaust.
What is reversible and irreversible process?
Very simple The Reversible Process: That type of process that work cycle, it mean to complete revolution and come back to the initial point from where it start. Example are Carnot Cycle. Two and Four stroke engine. Irreversible Process: Opposite to reversible process called irreversible process. Example are Electricity
What is mean effective pressure in IC engine?
Mean effective pressure (mep ) is a parameter indicating a engine's performance, which is obtained by dividing mechanical work done in a cycle (W)by volume swept in a cycle (V). Clearly work is the product of pressure and volume or torque and angle. Since torque is a measurable quantity, the work per cycle can be calculated as W = T * 2pi ( 2 stroke engine), W = T * 4pi ( 4 stroke engine) therefore mep = W / V = T * 2pi / V or T * 4pi / V
What is Camless engine technology?
cam less engine technology is the use of solenoids to open and close the intake and exhaust valves in a gasoline engine. Instead of using a camshaft, which has fixed timing limitations, solenoid controlled valves have unlimited timing ability therefor giving the modern engine maximum fuel efficiency and optimizing power and torque outputs on the fly via Computer controlled.
Are the tugboat engines are two stroke or four stroke?
For the most part, Tugboat Engines are LARGE two stroke (or two stroke cycle) Diesel Engines which provide High Combustion Temperatures and Pressures, High Horsepower typically > 1000 and High Torque, at relatively low speed. As an example of the two stroke diesel cycle engines ability to produce high horsepower and high torgue at low speed, The Union 6V Diesel was produced during World War Two as an engine for locomotives for the transport of industrial materials used in the production of weapons and armament. It was functionally an inline or straight block configuration, but because adjacent cylinders were actually offset from centerline by 6 degrees in opposite directions (cyl 1 offset to starboard by 6 deg from centerline and cyl 2 offset to port by 6 degrees from centerline, and so on) it was technically a V configuration. It was subsequently utilized by the Navy in a few instances as main propulsion for Yard Craft, mostly Yard Oilers (capable of hauling around 240K to 280K gallons of fuel to be loaded to ships at dock in a given harbor). This engine produces in excess of 1000 horsepower at a maximum 325 RPM. It idles at 125 RPM, and at that idle speed produces very large smoke rings out it's exhaust stack. This was also a naturally aspirated diesel (meaning it had no blower or turbocharger). It was also a directly reversible engine in that to reverse your direction of travel, the engine had to be shut down, the camshaft shifted utilizing a dual direction air cylinder, a pinion gear mechanically moved into position between the starter gear and the flywheel gear, and the engine then was restarted in the opposite rotation, turning the main output shaft in the opposite direction. No transmission or reduction gear.
Where is the camshaft located in a two cycle engine?
A two-stroke engine does not have a cam or camshaft. Seeing there is no intake/exhaust valves it would be pointless to have a camshaft.
How many revolution are made by crankshaft in a four stroke cycle engine?
it varies a lot
How many revolutions of the crankshaft does it take to complete the cycle of a 4-stroke cycle engine?
It takes two revolutions of the crankshaft to complete the cycle of a 4-stroke cycle engine. Each revolution includes the intake, compression, power, and exhaust strokes of the engine.
How much bigger is the camshaft in a 2-cycle engine than the crankshaft?
There is no camshaft in a 2-cycle engine.
In two stroke engine Crankshaft how many revolution takes place?
A two stroke engine has half the strokes of an otto (or four stroke) engine, therefore it takes two crankshaft roatations to complete a cycle on a four stroke engine and only one revolution in a two stroke engine. There are several types of two stroke engines, the different types have to do with how the receive the air/fuel mixture, also you have two stroke diesel engines.
What is the name of the 4 stroke engine cycle?
'a 4 stroke engine cycle' is usually what it is called...
What is the function of camshaft half engine speed?
The camshaft operates the valves on a 4 cycle engine.
How many rotation of the crankshaft are required to complete each stroke of a four stroke cycle engine?
A stroke is half of a revolution.2 revs is 4 strokesone another is the samea 4 stroke engine goes through 2 revolutions to complete one cyclea cycle is an X number of strokes to complete combustion and power process in an internal combustion engine'The intake stroke is the first downward movement of the piston, half of a revolution. The next half of a rev is the compression stroke, then power stroke, and exhaust stroke.

What is an ottoman cycle?
the four stroke engine cycle
What is the difference between cycle and stroke?
In a two-stroke engine, two strokes is one cycle. In a four stroke engine, four strokes is one complete cycle. A stroke is a part of a cycle. Remember that the "up" motion and the "down" motion each count as one stroke.
The first stroke of a two stroke cycle engine is?
It is called the compression stroke.
