Why Is Compression-Ignition Engine Important?

The compression ignition engine inherently needs a high-compression ratio to create the necessary conditions for auto-ignition. High-compression ratio is one design characteristic to improve efficiency. In addition, the compression ignition needed no throttling to control the power output of the engine.

What are the advantages of compression ignition engine?

The CI diesel engine has a higher mechanical efficiency as it avoids pumping losses at part load. 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 compression ignition system?

: 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.
