Fuel
Compression
Combustion
Exhaust SI (Gasoline) Engine CI (Diesel) Engine Lower power density
Heavy and bigger
High Cost (twice of the same power gasoline engine)
High NOX and particulates
Poor cold start
Higher fuel economy
(20%-30%) High power density
Light and compact
Lower cost

Lower end pipe emission
Good cold start
Lower fuel economy Genius is one percent inspiration, ninety-nine percent perspiration. ( Thomas Edison ) Thank you for your attention ! Any questions are welcome … References: http://www.mansory.com/en

Engine: Eternal combustion, Internal Combustion
SI (Spark Ignition) Ignited by spark
CI (Compression Ignition) Ignited by compressing
SI engine advantages over CI engine:
1. High power density
2. Light and compact
3. Lower cost
4. Lower end pipe emission
5. Good cold start
CI Engine advantage over SI Engine:
1.Higher fuel economy (20% - 30%)
Emission could be measured by GC-MS
