A four-stroke engine is classified as an internal combustion engine because it generates power through the combustion of fuel and air within a confined space, typically the engine's cylinders. During its operation, the engine goes through four distinct strokes: intake, compression, power, and exhaust, all occurring within the cylinder. This internal process allows the engine to convert the chemical energy from fuel into mechanical energy, driving the vehicle or machinery. The combustion occurs internally, hence the term "internal combustion engine."
Nikolaus Otto invented the four-stroke internal combustion engine
In 1859 a Belgian engineer Jean Joseph Étienne Lenoirdeveloped the first internal combustion engine. It was a single-cylinder two-stroke engine which burnt a mixture of coal gas and air ignited by a spark-ignition system. He patented it in 1860.Nicolaus Otto invented a gas motor engine in 1876. He built the first practical four-stroke internal combustion engine, called the "Otto Cycle Engine", and built it into a motorcycle.Otto's patent was later revoked when it was contested by Beau de Rochas.
One of the earliest uses of the internal combustion engine was in the 1860s with the development of the Otto engine by Nikolaus Otto. This four-stroke engine, which ran on gasoline, significantly improved efficiency and paved the way for modern automobiles. Another notable example is the gas engine created by Jean Joseph Etienne Lenoir in 1859, which was one of the first practical applications of an internal combustion engine for powering vehicles.
1886 - Karl Benz received the first patent (DRP No. 37435) for a gas-fueled car. 1889 - Gottlieb Daimler built an improved four-stroke engine with mushroom-shaped valves and two V-slant cylinders. 1890 - Wilhelm Maybach built the first four-cylinder, four-stroke engine.
Two-stroke engines generally pollute the air more than four-stroke engines due to their design and operation. In a two-stroke engine, the combustion cycle is completed in just two strokes of the piston, which often leads to incomplete combustion and unburned fuel escaping during the exhaust phase. Additionally, two-stroke engines typically mix oil with fuel for lubrication, resulting in higher emissions of hydrocarbons and particulate matter. In contrast, four-stroke engines have a more efficient combustion process and separate lubrication systems, leading to lower emissions.
A two stroke engine combines the four strokes of a typical internal combustion engine into two strokes instead of four.
Nikolaus August Otto
The four strokes of an internal combustion engine are intake, compression, power, and exhaust. During the intake stroke, air and fuel are drawn into the combustion chamber. In the compression stroke, the mixture is compressed. The power stroke is when the compressed mixture is ignited to create power, while the exhaust stroke expels the burned gases from the chamber.
The four-stroke engine used in automobiles is an example of an internal combustion engine.
Nikolaus Otto invented the four-stroke internal combustion engine
A four stroke internal combustion engine can have any number of pistons, from one to one million. They usually have even numbers in order to maintain engine stability. The "four stroke internal combustion" signifies the type of engine. There are two stroke internal combustion engines, mostly one or two cylinder engines used in lawn mowers. An internal combustion engine is one that ignites an air fuel mixture within itself and uses the resulting explosion for power. There are external combustion engines, which are usually powered by steam heated in a separate container and pumped into the engine. Four stoke engine utilize a four step (or stroke) process in order to run. The steps are the intake stroke, where the engine breaths in air and fuel, the compression stroke, where it squeezes the air and fuel, the power stroke, where it ignites the air fuel mixture, and finally the exhaust stroke, where it pushes the remains of the ignition out. See the attached link for a graphic description of how two and four stoke engines work.
If you mean who made the first combustion engine, i have no idea, but the first Four-Stroke engine was made by Nikolaus Otto.
This refers to the four-stroke internal combustion engine, First phase- intake, then compression, then power stroke, then exhaust.
OPtherwise known as Internal combustion engine with 4 cycles- Induction, compression, power and exhaust
Intake happens afer the exhaust stroke and just before compression.In a four stroke, 'otto cycle' internal combustion, engine.
The four stroke internal combustion engine. One of the most important landmarks in engine design comes from Nicolaus Otto who in 1876 invented an effective gas motor engine. Nicolaus Otto built the first practical four-stroke internal combustion engine called the "Otto Cycle Engine," and when he completed his engine,
A 4 stroke engine is also referred to as a four cycle refers to the internal combustion whereby the piston completes 4 separate strokes with a single thermodynamic cycle.
