Comparison Of Si And Ci Engine

Comparison Of Si And Ci Engine. Characteristics of si engine and ci engine; Radial si engines are used in small aircraft.

Difference Between Si Engine And Ci Engine - Mechanical Education
Difference Between Si Engine And Ci Engine - Mechanical Education from www.mechanicaleducation.com

These engines are more efficient compare to si engines. Lighter construction due to lower peak pressures. Ci engines make more noise and vibration compare to si engines.

Ci Engines Make More Noise And Vibration Compare To Si Engines.


High thermal efficiency because of the high compression ratio. In si engines petrol or gasoline is used as fuel, hence these engines are also called petrol engines. More power is produced because of the high compression ratio.

Si Engines Use Petrol Or Gasoline As Fuel, Where As Ci Engines Use Diesel, Kerosene As Fuel.


5.si fuels should have long. Now you should ask yourself these questions. Lower thermal efficiency because of the low compression ratio.

These Engines Have Lower Cost.


Pressure and temperature in diesel cylinder are higher than those of si engines, as well as the degree of efficiency. More hydrocarbon is produced because of the incomplete combustion, leading to air pollution from the exhaust. These produces more vibration compare to si engines.

100 And Low Cetane Rating Of About 20, Whereas Diesel.


Comparison of initial and maintenance costs 3. Advantages and disadvantages of ci engine. 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.

Figure 2 Shows The Differences Among Si, Ci And Hcci Engines, Where Si Engines Have A Spark Plug To Initiate The Combustion With A Flame Front Propagating Across The Combustion Chamber.


Ci engines are higher in weight. Diesel engines works on diesel cycle. 20 rows ci engine.
