Proton CamPro engine
The Proton CamPro engine is an internal combustion engine manufactured by Malaysian automobile company Proton Holdings. It is the first engine model to be developed in-house by Proton.
The name CamPro is short for "cam profiling". This engine powers the Proton Gen-2, Proton Satria Neo, Proton Waja Campro, Proton Persona, Proton Saga, Proton Exora, Proton Preve, Proton Suprima S and Proton Iriz.
The CamPro engine was created to show Proton's ability to make its own engines that produce good power output and meet newer emission standards. The engine prototype was first unveiled on 6 October 2000 at the Lotus factory in UK before it debuted in the 2004 Proton Gen•2.
All CamPro engines incorporate drive-by-wire technology (specifically electronic throttle control) for better response, eliminating the need for friction-generating mechanical linkages and cables.
The first CamPro engine made its debut in 2004 fitted to the newly released Gen•2 models. It was codenamed S4PH and was a DOHC 16-valve 1.6-litre engine that produced 110 bhp (82 kW) of power at 6,000 rpm and 148 N⋅m (109 ft⋅lbf) of torque at 4,000 rpm. The S4PH engine was ironically not equipped with Cam Profile Switching (CPS) even though its Campro designation was an abbreviation of Cam Profile Switching. It also lacked the Variable Inlet Manifold (VIM) technology of later CamPro engines. Proton also produced a 1.3-litre version of this original CamPro engine and codenamed it S4PE.
Even though the S4PH engine had contemporary maximum power and torque outputs, its performance was reportedly sluggish in real world driving. This performance deficiency was attributed to a pronounced torque dip in the crucial 2,500 to 3,500 rpm mid engine speed range where torque actually decreased before picking up back to the maximum torque level at 4,000 rpm. This torque characteristic could also clearly be seen in manufacturer published engine performance curves.
The original Campro 1.3-litre variant produced 94 bhp (70 kW; 95 PS) of power at 6,000 rpm and 120 N⋅m (89 lb⋅ft) of torque at 4,000 rpm, again contemporary outputs for a 1.3-litre passenger car engine of the time. This engine also displayed a torque dip in the mid engine speed range, similar to the one in the larger variant.
The bore x stroke dimensions for both engines are as follows:-
