What is the difference between a Gas turbine engine and a piston engine?
a compressor does work on the gas , raising its pressure and temperaturea turbine does the reverse , it expands the gas as it passes through the turbine, extracting energy from the gas to do mechanical work.For a typical jet engine , the flow track on a compressor is of a converging cross section while is it diverging for the turbine, which is as per gas dynamic laws.The Turbine does two things here in the jet engine, one ,it runs the compressor and two, expands the gas to the propelling nozzle which produces thrust by accelerating the gas upto its exit.
How does a piston moves downward in d suction operation in a 4stroke engine?
The piston is moved by the connecting rod which in turn is moved by the crankshaft. It is only on the power stroke that the piston moves the connecting rod, crankshaft and all the rest of the engine, in all the other strokes the engine, crankshaft and connecting rod move the piston.
What are the different phases of combustion in a petrol engine?
1) Inlet, 2) Compression, 3) Ignition, 4) Exhaust. Otherwise known as; Suck, squeeze, bang, blow. 1) Fuel / air mixture is injected/drawn into chamber. 2) Mixture is compressed by piston. 3) Spark, and mixture burns, pushing piston down 4) Piston returning to top of cycle pushes out burnt exhaust gases.
What is an piston cooling oil nozzle?
It is a little nozzle which is pointed towards the beneath of a piston in an internal combustion engine. It is linked to the pressurised side of the oil system, so cool oil coming directly from the oilcooler will spray onto the piston and cooling it instead of just cooling around the cylinder. This enables the engine to run a much more efficient combustion without the chance of melting a piston or overheating the engine which could lead to engine failure.
What does a komatsu 6D125 engine mean?
It means that it is a six cylinder naturally-aspirated diesel engine with 125 mm piston bore
What is missfiring?
((Missfiring)) it's when a piston in the engine. Doesn't get a spark from the sparkplug to ignite the fuel in the cumbustion chamber.
What is an internal-combustion engine?
An internal combustion engine is an engine that uses air, fuel, and spark to create the power to move. A perfect air-fuel mixture is pulled into the cumbustion chamber, its compressed by the piston, and once its compressed the spark plug ignites the air-fuel mixture and the process is completed.
How do you run large engine with broken piston rings?
Running an engine with broken piston rings will cause damaging scoring in the piston chamber, and is not to be recommended.
What is a pistol ring in a car used for?
You mean a piston ring. It seals the gap between the piston and the chamber in your engine
Compression ratio of the internal combustion engine is defined as?
The compression ratio of an internal-combustion engine, or an IC engine as it is more commonly called, is the ratio of the volume the highest capacity of the combustion chamber to its lowest capacity. In the IC engine, the piston makes a stroke, resulting in the compression of the air in the combustion chamber - the ratio between the volume of the cylinder and combustion chamber when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke, is the compression ratio.
What is an open combustion chamber?
That refers to the area where a piston goes un and downin a 4 or 2 cycle engine and burns the fuel it has pumped into that chamber compressed by the piston and ignaited by the spark plug.
How do you stop oil burning?
your car has oil burning in the combustion chamber of your engine , need to rectify the engine block and replace piston rings
Why do you need a piston?
A piston is a moving part that allows air and fuel to flow in, and pushes exhaust out. It's a combustion chamber...want to do away with them just get a Rotary Engine.
Why does car need a fuse?
To start the engine to create that little spark the egnights the fuel to make exsplosions in the piston chamber so the piston move up and down.
What is the purpose of the piston ring on a petral engine?
The rings seal the space between the piston and the walls of the combustion chamber, so that there is enough compression of the fuel-fair mixture. They also prevent engine oil from being sucked up into the chamber, which is why blue smoke is a warning sign of bad rings.
What is the compression ratio for an engine?
It is the volume of the cylinder/combustion chamber/head gasket/piston volume(dish/dome) when the piston is at the bottom of the stroke divided by the volume when it is at the top of the stroke.
What is function of a piston in a petrol engine?
Answer The piston is a key engine part, which is used to compress gases withing the combustion chamber or cylinder of an engine. The piston is sealed with a piston ring, often constructed under freezing temperatures, to allow expansion and therefore complete sealing, to seal the chamber to prevent leaks, or dangerous gases escaping. As the piston moves downwards, a valve opens to allow fuel into the chamber, this fuel is then compressed, combusted and expelled. All of which is transferred through the cam or prop shaft, through a differential and gear box, into the axle and ultimately onto the road via the tire.
