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…
Experienced mechanics share their insights in answering this question :
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.

I have a 2010 camry. I just recently replaced the engine with a 2014 camry engine. Now I have Four engine lights on. I replaced on
ANSWER : If you swapped the engine from a vehicle that is 4 years newer than the car is then you are going to have electrical and sensor incompatibilities that may not be able to be fixed by just a few sensor replacements. There were many changes in computer and emission related items between 2010 and 2014 engines. I would recommend having a mechanic like one from YourMechanic come to you and compare the two engines to isolate the possible differences and see if the problem can be fixed.

Check Engine light on. Would the computer give all error codes in one shot? How do we know the engine’s condition?
ANSWER : Hi there. From the description you have provided, I’m am inclined to agree with your assessment of a used engine being installed in your vehicle. An inspection of the engine, by a qualified technician could determine whether the engine is sound. The Check Engine Light on and having a TPS (throttle position sensor) code does not necessarily mean the sensor is at fault. Circuit tests should be performed to confirm the fault. The likelihood of the ECM (electronic control module/computer) giving you all the codes at once is remote. Other component failures could occur. Address those as they come up. Even though you already made the purchase, I recommend having your vehicle inspected by a certified technician so that you can get a thorough evaluation of the car’s true condition.

Engine malfunction light, reduced engine power, engine powered down
ANSWER : Hi there. There are a lot of things that can cause this on your 2012 BMW M5. I usually start by scanning the computer for codes to see what comes up. If there are not codes then I load test the alternator and the battery to see if they are failing. Low voltage in the electrical system will cause this. If that is fine, then it is usually caused by a failing throttle body. I have seen a lot of these fail due to the motors in them hanging up. If the problem is only happening intermittently, this can make the issue hard to duplicate, but you can still have tests done on the car. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to test the vehicle and diagnose the Engine Malfunction Light.

Check engine light refuses to go off after engine replaced
ANSWER : Hello there, you have a long series of issues going on with your 2013 Hyundai Sonata. If you keep getting a repeating oil light on than there is likely a fault in that system.
Since this fault has lasted after the engine was replaced it could be a oil pressure sensor, wiring harness fault, ECU fault, oil pump, oil strainer clogged, or low oil pressure.
To diagnose this issue properly you need a complete vehicle inspection to start from square one and identify the root cause of all this.

How do you replace the rear & side engine mounts without lifting out the engine? & how do you lift the engine out?
ANSWER : Hi…thank you for your questions. If required in the application, a portable engine support bar is used to support an engine during mount replacement. The support bar has lifting capability as well so that the mount can be unloaded and removed. If a particular repair application requires a "crane" (complete engine removal for instance), such are portable these days in any event. With regard to the exhaust system repair, mechanics use ramps to gain access. Six ton portable jack stands will safely support a car two feet into the air which provides more than enough access to repair or replace any exhaust system component. If you desire replacement of the mounts, please refer to YourMechanic’s motor mount replacement service page. For exhaust leaks, please use the exhaust system inspection/repair page page. Once on each of those service pages, if you click on "Get a Quote" and enter your vehicle information (year, make, model) you can obtain cost info and schedule the service. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Reduce engine power / check engine light is on
ANSWER : Hi there. Most of the time, reduced engine power is caused by a restriction of fuel, or the throttle body’s inability to efficiently mix air and fuel. This could be caused by a failing mass air flow sensor, EGR valve or other fuel system components. Since the check engine light is on, you should have a professional mechanic complete an inspection at your location to determine what codes are stored and which components require repair. This should resolve your issue.

Hey Allen. I just rebuilt (?) the engine on my 06 Acura TL. Now the engine line went on. They told me the engine? can blow up if I
ANSWER : Hi there. I think it may be a good idea to find a new mechanic. Fortunately, our mobile mechanics are able to complete most diagnostic inspections and complete a lot of repairs services at your location, and on your schedule. In what you are describing above, the current issue seems to be with your EVAP system, which is designed to relieve pressure in the fuel tank and also collect harmful vapors before they escape into the air. Now, in regards to the car "blowing up"; that’s a bit dramatic, but it is important to have your issues repaired if it’s related to the EVAP system. Here is what I would recommend. Set up an appointment to have one of our mobile mechanics come to your location to complete a check engine light inspection – (click here to set up an appointment). This will allow them to download the stored error codes that cause the light to illuminate and determine what parts need repair or replacement. Then, they’ll be better prepared to provide you with a repair estimate and complete the repairs in most cases for you.
