Dr. Rudolph Diesel first worked on the Diesel cycle using powdered coal dust on a slow speed two stroke engine. So the Diesel cycle came first and later developments led to Diesel engines. Sadly, Dr. Diesel committed suicide by jumping from a boat.
A diesel engine is an internal combustion engine which uses the heat of compression to ignite the fuel/air mixture in the third stroke of the 4-stroke cycle, while the petrol engine is an internal combustion engine which uses an electrically-generated spark system to do the ignition. Diesel engines have a higher efficiency compared to petrol engines. In simple terms this means diesel engines can give 50% or more miles per gallon than petrol engines.

In a 4-stroke engine, one complete engine cycle consists of four strokes: intake, compression, power, and exhaust. This cycle requires two full rotations of the crankshaft, which equals 720 degrees of crankshaft rotation. Each stroke corresponds to 180 degrees of crankshaft movement, collectively completing the cycle.
In my point of view two stroke engine is the best engine ,because in two stroke engine there are only two stages or two stroke .In which one stage complete the two process frist is suction & second one is compression ,in these two process completes in one stage. The best advantage of this engine is the in every cycle there is a power stroke due to which the engine performance is very good . But the biggest disadvantage is the fuel consumption . Which after some time reduced by the resarcheres.
Scavenging
The 4 stroke or 4 cycle engine was invented in 1876 Nicholas Otto in Germany. This is the earliest 4 stroke and is commonly called the Otto cycle engine. The Diesel 4 stoke was invented in 1893 by Rudolph Diesel in Germany.
'a 4 stroke engine cycle' is usually what it is called...
Scavenging is the process for pushing out burned gases and drawing in fresh air for the next cycle. It requires the exhaust to be tuned correctly for the specific engine to get the most benefit. A good example would be expansion chambers on a two stroke motorcycle engine. They're designed to help suck out the exhaust gas, thus helping pull in (scavenging) the fresh charge.
diesel cycle
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.
the four stroke engine cycle
Dr. Rudolph Diesel first worked on the Diesel cycle using powdered coal dust on a slow speed two stroke engine. So the Diesel cycle came first and later developments led to Diesel engines. Sadly, Dr. Diesel committed suicide by jumping from a boat.
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.
It is called the compression stroke.
Is it a 2 stroke or 4 stroke engine, Gas or Diesel. I would suggest consulting your owners manual. On a 4 cycle engine use SAE 10w30 synthetic.
It depends, a chainsaw or weed wacker can be run upside down because the two cycle oil mixed in the gas is what lubes the engine. A Detroit Diesel two stroke engine can not.
