it's funny cos their older NA engine quite reliable (with lower power) maybe just glitchy electronics and sked overheat... biggrin.gif

overheat as in temp rise.. nearly to red , still can drive wot..

electric glitch, error code come out warning sign, engine still running, if more serious like bad coil (which i kena before on 407) they will put engine to limp home mode, maybe hard to rev over 3k rpm so why cannot drive?

small turbo engine also got limit, cos at the end of the day energy conservation is more important, you can only get so much out of efficiency to move a car, but we also need to recover kinetic energy from moving vehicle also since already paid with fuel to get it moving, so hybrid is still way forward...

i remember lotus did a range extender engine with 50KW right? to power the pure electric vehicle on gas if needed.. that would be interesting as well.

stilll got but maybe used for their version of proton emas.. our proton emas dunno yet will use which engine..
if family Y is not ready then theyll source mitsu? engine agen?

Hybrid Campro engine

In March 2007, PROTON and Lotus have announced their concept model of a Proton Gen•2 powered by a hybrid powerplant that uses the CamPro engine. The concept model was revealed during the 2007 Geneva Motor Show from 8 ~ 18 March 2007.[7]

The hybrid power-plant system, which is known as EVE system (Efficient, Viable, Environmental) will be using the same S4PH engine as the one that powers the present gasoline version of the Gen•2, combined together with a 30 kW, 144V electric motor. The main purpose of the hybrid powerplant system is to provide a hybrid system that can be retrofitted to existing models, retaining the same power-plant and also eliminating the need to develop a completely different platform, like the Honda Civic Hybrid. Unlike the IMA (Integrated Motor Assist) technology in the Civic Hybrid that uses a bulky Ni-MH battery pack, the EVE Hybrid system will use a Li-ion battery pack inside the engine bay.

The EVE Hybrid System will have 3 key technologies:

    "Micro-hybrid" start-stop system - An integrated starter-alternator system is installed to switch off the engine automatically when the engine stops, for example at a traffic light. The engine will automatically restart when the gas pedal is depressed.
    Full parallel hybrid technology - Combines the existing S4PH engine with a 30 kW, 144V electric motor, resulting in higher power (141 bhp combined), higher torque (233 N-m combined), lower emission (up to 22% carbon dioxide reduction) and better fuel economy (up to 4.6 L/100 km). The system also includes regenerative braking system.
    Continuously Variable Transmission (CVT) - The CVT system provides an infinite number of gear ratios for better efficiency.

The combined power and torque for the power-plant system are as follows:

    Max power (gasoline engine only): 110 bhp (82 kW; 112 PS) @ 6,000rpm
    Max torque (gasoline engine only): 148 N·m (109 ft·lbf) @ 4,000rpm
    Max power (combined): 141 bhp (105 kW; 143 PS) @ 5,500rpm
    Max torque (combined): 233 N·m (172 ft·lbf) @ 1,500rpm (limited to 180 Nm continuous)

bump..

just came back from test drive preve turbo(2nd time)--1st time the car is jerking like hell,pissing me off

the test car can feel sharp response of throttling,but to feel the surge of excitement,u need to switch the gearknob to the left(+/- manual mode),as D mode is slow macam siput(fuel-save mode ler)

to really enjoy the sudden surge of throttle,dont use paddle-shifter at the back of the stereng,its really slow response compared to the manual +/- mode
i think coz of electronic response from the wire at the stereng is not fast enough to deliver the input to the gearbox



as expected,shitty plastic interior,flimsy dashboard (but with some useful gajets & small HUD)-but i dont care much as long as the engine+cvt3 is good enough


QUOTE(harryfoo @ Feb 16 2012, 07:59 PM)
Merc manage to extract 270Nm of torque from it's 1.8 litre 4 cylinder engine though.

its not the engine but how much the gb can hold the much torque,the cvt3 on preve turbo surely grinded to pieces already if reached that figure
but i think if proton can sell preve turbo with manual 6-speed gb(which on the basic preve),sure the manual gb can hold much more torque than the cvt3

engine's fan is noisy as hell,but i used to pug 308 turbo engine noise also,no difference both bunyi macam kipas lori wan

I meet a new colleague just joined previously from proton R&D department, he said the engine came about because they bought lotus but had nothing for it to do, so they decided to all them to develop a new engine but lotus had never done so before on their entire life. Hence they went to all sports of people to get their inputs and eventually hacked together what is the campro engine today

The emphasis on the development of CFE focuses more on torque rather than horsepower.

but only 200Nm wor, and every other manufacturer with a forced induction engine of 1.6-1.8L would be producing 240-260NM of torque..
