Combustion Engines

An SI engine ignites the fuel with a spark (SI = Spark Ignition) whereas the CI engine ignites the fuel with heat generated from compression (CI = compression ignition)

Internal combustion.

Marine engines are almost always based on an automotive/ industrial counterpart. They are marinated to have a cooling system that uses the seawater to cool them directly or indirectly through a heat exchanger.

Yes

If you take good care of them, like classic car owners, they could last for decades. But you should be EXTREMELY dedicated to keeping the engine running. Replacing it would cost a lot but then again so would maintaining the old one. Still, all you have to do is make sure the engine is properly maintained.

1893 by Rudolf Diesel.

A nano combustion engine is a type of engine that utilizes nanotechnology to improve combustion efficiency and performance. By incorporating nano-scale materials, such as catalysts and additives, into the combustion process, these engines aim to achieve higher fuel efficiency and lower emissions compared to traditional combustion engines.

Before the internal combustion engine, various forms of mechanical propulsion were used, such as steam engines, horse-drawn carriages, and sailboats. These technologies powered transportation and machinery in the 18th and 19th centuries.

A diesel engine is heavier than a petrol engine because some parts in a diesel engine are made from cast iron such as cylinder sleeves etc. The weight difference is usually between 10-20kgs.

A 2-stroke engine is a type of internal combustion engine, and a generator is something that turns a motion into electricity.

DOHC means Double Over-Head Cam. The engine has 2 camshafts that are located within the cylinder head at the top of the engine.

Not totally, just because it is an internal combustion engine doesn't exactly mean that fossil fuels need to be burnt. The concept of the Internal Combustion engine is relatively reuseable, the major problem with it is its efficiency. As we all know a good petrol engine will probably get around 25 - 30% efficiency as in driving force. The rest is lost mostly to either friction or heat.

If these problems can be rectified the Internal Combustion engine could possibly run on fossil fuels for another century (Oil depending/Government b*llshit). Yet fuel cells and other means of power are being developed so this depends on the movement of technology.

YES

To let the fuel and air into the cylinder and to let the exhaust out. Inside a motor there is a space (cylinder) where fuel and air is compressed by a piston then ignighted by a sparkplug. A valve is a little round disk with a stem coming out of its middle. The valve moves into that space creating an outlet around it past the stem. Every cylinder will have at least two valves.. 1 for fuel & air and 1 for exhaust. Hope that was helpful I tried to keep it simple as possible.

Although there had been various examples before, English scientist Samuel Brown was in 1823 (revised in 1826) the first man to patent the internal combustion engine.

You can convert a petrol engine into a diesel engine by changing the fuel injectors. The fuel filters will also need to be changed.

They are!!!

Two main kinds: true backfire is when flame leaps out of the intake manifold ... usually when trying to start the car.

The more common form is when a air/fuel mixture builds up in the exhaust system and ignites. Often caused by a single cylinder not firing every time (or not at all).

The 200S is powered to life by an overhead cam four-stroke single cylinder 192 cc engine

Rocks, hammers, and baseball bats.

Pretty much detonation can hard your engine if the timing is off and your using crappy octane fuel. over reving the engine.

LAst but not Least, the worst enemy of any Engine is HEAT!!

The traditional such device for a gasoline engine is a carburetor, but modern engines can also use injection nozzles; these are standard for diesel engines.

engines cease because, it is our misconception that the cylinder of the engine is cylindrical,in actual the cylinder walls are slightly slanting.

and th diameter of the piston is a bit less than that of the cylinderwalls,which is known as clearance,,which is formulated for the smooth running of piston,,but when the temperature inside the cylinder increases above a certain level,the walls of the cylinder and the piston expands.but the expansion ratio is different for both,,as the cylinder is made of cast iron and piston with aluminium,which decreases the gap to certain level that there is no movement of piston,which is called as ceasinf of engine.

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.
