Maybe some of you one of potential buyer for Proton Exora Bold and waited for their engine. If you read at the website or any car blog it will tell you that the MPV used turbocharged engine, the Campro Charged Fuel Efficiency (CFE). So, what is the Campro CFE?
Let’s read it
Before get into the CFE technology let’s know about what is really the Campro. Campro is short name for Cam Profiling and this engine was unveiled on 6 October 2000 at Lotus factory before debuted in the 2004 Proton Gen-2. Back to the Campro CFE engine, it is the ligh pressure intercooled turbocharged version of the 1.6L Campro engine. It could boost pressure of 0.75 bar (a bit technical.. can’t understand). The concept of small displacement engine but forced aspirated to produce the power output is a similar concept like Volkswagen TSI twincarger technology and the Ford EcoBoost engine. The engine is capable to produce 138 bhp (103 kW; 140 PS) @ 5,000 rpm of power and 205 N·m (151 ft·lbf) @ 2,000-4,000 rpm of torque.
This engine has been used for 2012 Proton Exora Bold and 2012 Proton Persona R (hmm.. this engine also for Persona, cool..)For Proton Exora Bold the CFE key Features :-
1. Cylinder Head Assembly – High strength, optimised coolant and port flow, sodium filled exhaust valves for resistence to high temperatures and cylinder pressure ( it means good for long driving).
2. Intake Variable Valve Timing – Optimised performance, fuel economy and emissions.
3. Cylinder Block Assembly – Optimised coolang jacket with piston cooling jets for durability
4. High Flow Oil & Coolant Pumps and High Capacity Oil Cooler – Optimised cooling and lubrication for durability
5. Forfed Steel Crankshaft – Durability at high cylinder pressures
6. Direct Acting Mechanical Tappets – Reduced friction and improved efficiency
7. Close Coupled Catalyst with Thin Wall Substrate – Fast light off for good emissions
8. Piston / Conrod Assembly – High strength forged steel connecting rod with high performance bearings and piston assembly.
