The diesel is more efficient but more expensive to build.
Diesel engines are more efficient than gasoline engines.

It will depend upon the conditions. Under normal operating conditions a diesel engine is more efficient than a petrol engine.
Diesel engine
Diesel engines are more efficient than gasoline because chambers are different. A diesel engine has better gas mileage.
Overall it is about 20%
Diesel Engine SFC is Specific Fuel Consumption of Diesel Engine. This used to know how efficient Fuel utilization of Diesel Engine to produce electricity. Usually formula of SFC is Fuel Consumption divided by Electricity Production (liter/kWh).
The gasoline engine came first. The gasoline engine was invented and patented in 1823 with the first efficient gasoline engine developed in 1876. The diesel was invented in 1893 which was 70 years after the gasoline engine.
Diesel engines are more efficient. They get better mileage, produce more torque, and last much longer than a gasoline engine. They are also more expensive to build.
2cylinder
It was cheaper to burn, there was no spark plugs, and it was a better efficient engine then others that were invented at the time.
