An internal combustion engine is where the pistons open up, gas goes in them and then they close. The pressure causes an explosive reaction from the gas. That reaction moves the piston up and down. The piston is connected to the transmission and drive train. The transmission is connected to the wheels and when the piston moves the transmission moves and so on. When the piston opens up again, the old gas leaves through the exhaust pipe and new gas goes into the piston repeating the cycle over and over again.
No the fuel is burnt inside the engine, hence the term "internal combustion"
A steam engine is a good example External combustion means the burning of fuel happens away from where the conversion to motion happens.
This is the process of burning
Steam EngineJet turbine EngineRotary EngineElectric EngineRocket EngineThe term 'engine' was originally coined to differentiate the "internal combustion" motor from all other previous types of motors. In the above mentioned answer, one should note that the jet turbine, the rocket, rotary and perhaps even the steam engines do have some sort of internal combustion. The proper term for the electric should be "Electric Motor"
Engine configuration is an engineering term for the layout of the major components of a reciprocating piston internal combustion engine. These components are the cylinders and crankshafts in particular but also, sometimes, the camshaft(s).
Otto (which started the term "Otto Motor" in Germany) In 1876 Nikolaus Otto built a four-stroke or "Otto cycle" internal combustion engine. Gottlieb Daimler & Wilhelm Maybach who had worked with Otto on his engine, parted company and in 1885 released their own much advanced version. In 1886 Karl Benz patented his "motorwagen" and is generally credited as being the father of the automobile.
The term you are looking for is "knock" in relation to combustion in internal combustion engines, specifically in the context of gasoline engines.
The previous answer was obscene and irrelevant. I removed it. Engine oil is combustible (i.e., flammable), whether it's new or old and dirty. It is a liquid petroleum product, and as such it's flammable. But if you mean combustible as in the term, "internal combustion engine", it is not a suitable fuel. In an internal-combustion engine, the rate of burn must be very rapid, or "explosive". Engine oil is not explosive under normal pressures. However, if pressure were very high, and if the motor oil were sprayed in tiny droplets into an oxygen-rich environment, it could become explosive enough to serve as a fuel for an internal combustion engine.
The term that describes a gasoline's ability to resist explosion during combustion is "octane rating." A higher octane rating indicates that the fuel can withstand greater compression before detonating, which helps prevent knocking and improves engine performance. This characteristic is crucial for optimal combustion in internal combustion engines.
A fire started without any help.
The term "Internal combustion" means the burning, or combustion of the fuel/air is detonated in an enclosed cylinder under compression, driving piston down. If the combustion was external, there would simply be an explosion in the air that produces no power.
Sounds like you misheard Hybrider which is a casual term referring to a hybrid car - one with an internal combustion engine (gas or diesel) and an electric motor, for example.
