Hello,my self shareef..I am a student of mechanical. Is there possible to insert a high elastic rubber and springs on top of piston to increase speed…
Combustion temperatures can run close to 2000 degrees. It’s not likely that any kind of rubber will survive. Also, the springs would need huge amounts of tension to keep up with the fast movement of the piston and that tension buildup would be severely slow with the piston reducing engine efficiency.

The core of the engine is the cylinder, with the piston moving up and down inside the cylinder. Other key parts include the spark plug, valves, piston, piston rings, connecting rod, crankshaft and sump.
The engine consists of a fixed cylinder and a moving piston. The expanding combustion gases push the piston, which in turn rotates the crankshaft. Ultimately, through a system of gears in the powertrain, this motion drives the vehicle`s wheels.
An engine is some machine that converts energy from a fuel to some mechanical energy, creating motion in the process. Engines – such as the ones used to run vehicles – can run on a variety of different fuels, most notably gasoline and diesel in the case of cars.
The engine is a lot like the brain of a car. It holds all the power necessary to help your car function. And without it, your car would be nothing.
A typical internal combustion engine has around 200 parts that need to be maintained and possibly replaced if they wear out. An electric vehicle takes that number down to around 20 parts. These figures don`t even factor in the transmission, a complex and expensive system that most electric vehicles skip altogether.
Power in kW = (Pm LAN/n 100)/60 in bar where Pm = mean effective pressure L = length of the stroke in m A = area of the piston in m2 N = Rotational speed of engine RPM n= number of revolutions required to complete one engine cycle n= 1 (for two stroke engine) n= 2 (for four stroke engine) Thus we can see that for a …
Engines are majorly classified into Two types , They are INTERNAL COMBUSTION ENGINE & EXTERNAL COMBUSTION ENGINE.
“Engine” is from the Latin ingenium: character, mental powers, talent, intellect, or cleverness. In its journey through French and into English, the word came to mean ingenuity, contrivance, and trick or malice.
The compressor, burner, and turbine are called the core of the engine, since all gas turbines have these components. The core is also referred to as the gas generator since the output of the core is hot exhaust gas.
In 1879, Karl Benz patented a reliable two-stroke gas engine. In 1892, Rudolf Diesel developed the first compressed charge, compression ignition engine. In 1954 German engineer Felix Wankel patented a “pistonless” engine using an eccentric rotary design.
“People use both interchangeably, but the difference is that motors run on electricity and engines run on combustion. The engine converts various forms of fuels into mechanical force, while the motor transforms electrical energy into mechanical energy.”
Typically, a bigger engine means more air and fuel, which in turn creates more power and gives a car more oomph.
The different parts that make up your car`s engine consist of: the engine block (cylinder block), the combustion chamber, the cylinder head, pistons, the crankshaft, the camshaft, the timing chain, the valve train, valves, rocker arms, pushrods/lifters, fuel injectors, and spark plugs.
Engine power is the power that an engine can put out. It can be expressed in power units, most commonly kilowatt, pferdestärke (metric horsepower), or horsepower.
What is engine liter? Engines are assessed and measured based on displacement, expressed in liters. Displacement refers to the amount of volume taken by all the cylinders in an engine. One liter is equal to 61 cubic inches.
Essentially, the larger the volume of the cylinder, the more room there is for air and fuel inside it, which dictates how much power it can produce. This was especially true of older engines, but the widespread use of turbocharging in modern engines means that smaller engines are much more potent than they were before.
Engine oil is comprised of two basic components–base oils and additives. The base oils constitute 70-90 percent of the total and are created from natural gas or crude oil, while additives round out the remaining 10-30 percent and can be variety of things. These additives include among other things: Dispersants.
Devices converting heat energy into motion are commonly referred to simply as engines. Examples of engines which exert a torque include the familiar automobile gasoline and diesel engines, as well as turboshafts. Examples of engines which produce thrust include turbofans and rockets.
The internal combustion engine is one of the most common types of engines in modern cars and is mainly used in petrol and diesel-powered cars. The engine features a spark-ignition system to power the car and is highly energy efficient, making it ideal for use in passenger and commercial vehicles.
Petrol cars are more powerful than diesel cars due to the higher RPM and initial acceleration. However, diesel cars have better-pulling power due to the higher torque the diesel engine produces.
The simplest and most common type of engine comprises four vertical cylinders close together in a row. This is known as an in-line engine .
These include the engine, propeller, induction, ignition, as well as the fuel, lubrication, cooling, electrical, landing gear, and environmental control systems. An aircraft engine, or powerplant, produces thrust to propel an aircraft.
Internal combustion gasoline-powered engines require six systems: fuel, exhaust, ignition, combustion, cooling, and lubrication.
Introduction. Engine valves are mechanically opened and closed, to admit air or expel exhaust gasses, into the engine cylinder(s); the valves are located in the head casting of the engine. The area where the valve seals against the head is called the valve seat.
