CFE (Charge Fuel Efficiency) Engine Spec

What can we make of the new CFE engine by Proton? The engine is slightly de-stroked by lowering the stroke ratio compared to its predecessor, the CPS engine. It is to accommodate the mild turbocharged engine to maintain it compression ratio at 10.0:1. Thus the need for the engine to be de-stroked. A high compression rate in a turbocharged engine could cause damage to the piston in the long run and this will affect the reliability of the engine itself.

Comparison Between CFE and CPS Engine.

The major thing i noticed is that Proton have now equipped the CFE engine with a Forged Steel Crankshaft. I would presume that this will overcome the issue of "broken crankshaft" often encountered by previous CAMPRO users. The con-rod (connecting rod) is also being upgraded to a High Strength Steel material and a performance con-rod bearing is being used. Now, you can constantly high rev this engine with a peace of mind. Proton also have equipped this engine with the Intake Variable Valve Timing. It can optimized the performance for adventurous driving and have a better fuel efficiency under normal driving condition.

 I would say that this new CFE engine by Proton is a very big leap in terms of their engineering and design capabilities. Looking at the pricing, i would say that it is a bargain indeed.
