Coming Back in 1990s Chapter 224

The small and medium-sized 45-kW diesel engine optimized by Fang Bo himself is an in-line two-cylinder four-stroke engine.

Test results show that the thermal efficiency can reach 45.5%, representing world-class technology.

The domestically produced non-supercharged inline two-cylinder four-stroke engine originally purchased had a thermal efficiency of only about 36.5%. It was shocking to see such a huge improvement.

Of course, in addition to the significant improvement in thermal efficiency, the lower noise indicates that the vibration level is very good, for example, the crankshaft processing accuracy is higher.

The crankshaft, piston and connecting rod are all produced by Xinghai Machinery Company, and the materials are from Baosteel.
