12 is the throttle of Crown 2.5 the same as that of Crown 3.0?

Similarly, the difference between 2.5 and 3.0 is only the volume of the cylinder.

The technical difference is that 3.0 is a little more perfect than 2.5, and the difference in parts is cylinder piston, connecting rod and crankshaft. There are only three differences. Now someone has changed the 2.5 engine to 3.0 by replacing these three parts, which is said to be no different from the manufacturer's 3.0 engine.

In addition, the reason why these two engines are not directly injected into the cylinder is very simple. The quality of gasoline is so poor that the engine will break down easily with this technology. The source of all evil is China Petroleum and China Petrochemical. 2.5 is a domestic engine and 3.0 is an imported engine.
