What are advantages of compression ignition over spark ignition?
CI engines have higher Mechanical Efficiency It does not need to manage the intake of air as it is operated with a heterogeneous mixture, thus the control of the load can be managed by the quantity of fuel injected into the cylinder.
What is the difference between spark ignition and compression ignition engines?
The Spark Ignition (SI) engine, as its name indicates uses spark to ignite the fuel. And in Compression Ignition (CI) engine, the air is compressed within the cylinder and the heat of this compression air is used to ignite the fuel.
What are the advantages of spark ignition engine?
Advantages of SI Engine SI engine produces low noise as compared to the CI engine. It requires less maintenance. The spark-ignition engine has a low cost as compared to the compression ignition engine. It is easy to start than a CI engine.
What are the disadvantages of compression-ignition engine?
Disadvantages:
- CI engines are higher in weight.
- These produces more vibration compare to SI engines.
- It creates unpleasant odour in exhaust.
- Higher cost.
What are the disadvantages of spark ignition engine?
SI engines have low efficiency compare to CI engine. These engines are not economical at high load. Higher fuel consumption.
What are the advantages of 2 stroke engines over 4 stroke engines?
Advantages
- Simple mechanism.
- Easy to start.
- It gives one power stroke per revolution of the crankshaft.
- It has no valves, so complicated valve actuating mechanism not required.
- It is light weight, 30\% lighter than the 4-stroke engine.
- It has few moving parts, so compact and simple construction.
Why is it called a compression-ignition engine?
Diesel engines are sometimes called compression-ignition engines because initiation of combustion relies on air heated by compression rather than on an electric spark. The fuel is introduced under high pressure either into a precombustion chamber or directly into the piston-cylinder combustion chamber.
What are the advantages of 2 stroke engines over 4-stroke engines?
What is compression-ignition system?
Definition of compression ignition : ignition in an internal-combustion engine in which the necessary high temperature is produced by compressing air in the cylinder before admission of the fuel (as in a diesel engine) compression-ignition engine.
What are the disadvantages of compression ignition engine?
What are the advantages and disadvantages of ice over ECE?
Reciprocating ICE offers several advantages over the ECE (steam turbines) such as (1) mechanical simplicity (due to absence of heat exchangers (boiler and condenser) in the path of working fluid); (2) works as lower average temperature than the maximum temperature of working fluid (high temperature occurs only of …
