Campro engine

The Campro engine is the first automotive engine ever developed together with Lotus by the Malaysian carmaker, Proton. The name Campro is short for Cam Profile. This engine powers the Proton Gen-2, the Proton Satria Neo, the Proton Waja Campro, the Proton Persona as well as Proton's future models. The Campro engine is aimed to show Proton's ability to make their own engines that produce good power output and meet newer emission standards.

All Campro engines incorporate with drive-by-wire technology (specifically electronic throttle control) for better response, eliminating the need for friction-generating mechanical linkages and cables. There have been some issues with cracking oil pumps but apparently Proton have introduced a new part recently to solve this problem. A recall has not been announced.

Basic DOHC engine

The basic Campro engine coded as S4PH is a basic DOHC 16-valve 1.6 L engine that produces 110 bhp (82 kW) @ 6,000 rpm of power and 148 N·m (109 ft·lbf) of torque. This is the engine that powers the Proton Gen-2. The S4PH engine can be fitted with Cam Profile Switching (CPS) and Variable Inlet Manifold (VIM) technology. Besides this 1.6 Litre engine, Proton has produced the 1.3 Litre version of the Campro engine.

Even though the S4PH engine seems to be quite powerful at higher revs, its performance is reportedly sluggish at lower revs and this is proven by driving the Gen-2 uphill where drivers who drive the manual transmission version have to shift a lot between 2nd gear and 3rd gear. This is due to its torque dip in the crucial 2,000 ~ 3,000 rpm operating range, where the torque actually decreases before picking up back to the maximum torque at 4,000 rpm. This torque characteristic can be clearly seen in manufacturer published engine performance curves.

Another engine option for the basic DOHC engine is a 1.3L engine coded as S4PE. The S4PE engine produces 94 bhp (70 kW) @ 6,000 rpm and the torque of 120 N·m (89 ft·lbf) @ 4,000 rpm, which is more powerful than the other 1.3L rivals, even with variable valve timing technology, it also (like its bigger brother) displays a torque dip at typical engine speeds of 2,000 to 3,000 rpm.

Campro CPS and VIM engine

The Campro CPS engine uses a variable valve lift system (Cam Profile Switching system) and a variable length intake manifold (VIM; not to be confused with the stand-alone IAFM used in the 2008 Proton Saga) to boost maximum power and improve the CPS engine's torque curve over the standard DOHC Campro engine.

The engine's Variable-length Intake Manifold (VIM) switches between a long intake manifold at low engine speeds and a short intake manifold at higher engine speeds. Proton is using a longer intake manifold to achieve slower air flow; as they found this promotes better mixing with fuel. The short intake manifold allows more air in faster. This is beneficial at high RPMs

The Cam Profile Switching (CPS) system uses a trilobite camshaft to switch between two different cam profiles. One cam profile provides low valve lift, while the other cam profile has a high valve lift. The low valve lift cam profile is used at low to mid engine speeds to maintain idling quality and reduce emissions, while the high lift cam profile is used when the engine is spinning at mid to high engine speeds improve peak horsepower and torque[2]. Unlike the other similar variable valve timing systems such as the Honda VTEC, the Toyota VVT-i and the Mitsubishi MIVEC which use rocker arm locking pins to change the valve timing, the CPS system uses direct-acting tappets with locking pins to change the valve timing and lift profile.

VIM switches from the long to short runner at 4,800 rpm, while the CPS system switches over at 3,800 rpm (4,400 rpm in the Proton Satria Neo CPS. The result is 125 bhp (93 kW; 127 PS) at 6,500 rpm and 150 N·m (110 ft·lbf) of torque at 4,500 rpm compared to the non-CPS Campro’s 110 bhp (82 kW; 112 PS) at 6,000 rpm and 148 N·m (109 ft·lbf) of torque at 4,000 rpm. Proton claims that there is better response and torque at low engine speeds of between 2000 - 2500 rpm.

The new CPS engine first made its debut in the facelifted Proton GEN2 launched in Thailand, and made its first Malaysian debut in the Proton Waja Campro 1.6 Premium (CPS). Besides the 1.6L version, the Campro CPS engine is also available in 1.8L version; however, the bigger 1.8L version has not yet debuted in any of Proton's car (as on 30 April 2008) but rather made its first debut in a Malaysian-made hovercraft.

Proton CAMPRO Engine Specifications

THE CAMPRO ENGINE



Developed in partnership with Lotus Engineering, this engine grants PROTON complete vehicle design independence. Its breakthrough engine technology produces low fuel consumption, yet gives rapid, high power response, and can even be produced to run on alternative fuels.

Its represents true world class powertrain engineering, and a revolutionary step forward in engine manufacture, with low toxic emissions, low noise levels and above all, highly economical maintenance of long service intervals.

Major design objectives :

* Space-saving transverse east-west direction engine installation
* Designed for long life of at least 10 years or 250,000 km
* Best performance in class
* Flexibility to use future technology (CPS & NGV)
* 80% recyclable to meet 2005 requirements
* Comply to future exhaust emission legislation requirement

CAMPRO UNIQUE DESIGN FEATURES

1.Modular Engine Design - Common Cylinder, Piston, Camshaft.

2.Design Protected for future Combustion Technology (AVT) , Performance Technology ( CDA & CPS), Low Emission (DI-NGV, Diesel.)

CAMPRO CPS ENGINE TECHNOLOGY (CPS & VIM)

The Campro engine utilizes two ingenious technologies to give high power and rapid response, whilst maintaining low fuel consumption. Cam Profile Switching (CPS) and Variable Intake Manifold (VIM) technology.
Together, these technologies give the best if both worlds, essentially combining the best characteristics of two different engines in one compact package. The usual reduction in peak torque caused by High Lift cams is corrected by the Long Runner. The short runner works with the high lift cams to re-tune the engine and generate more power at high speed.
CPS & VIM : How It Works

Engines create power from combusting a mixture of fuel and air. Valve lift creates a gap to draw air into the combustion chamber, and this gap influences the ratio of air in the mixture. Ordinary engines have fixed rate of valve lift, but Cam Profile Switching gives variable valve lift, for optimised airflow into the engine. A High Lift cam profile improves maximum power, whilst the Low profile offers fuel efficiency and low emissions.
Air is supplied to the valves by the engine’s intake manifold. Variable intake Manifold technology intelligently changes the rate of “breathing” according to the engine speed. At low speed, air will drawn through the Long Runner manifold. The resulting slower air flow allows more efficient, thorough mixing of air with fuel. At high speeds, the Short Runner takes over to supply more air for combustion, faster.
IAFM (Intake Air Flow Module)

The CAMPRO engine is now enhanced with a new air intake management system - the Intergrated Air Fuel Module (IAFM) technology. It helps the engine “breathe” better at offer you the best of both worlds - greater fuel efficiency at low speeds and better performance at high speeds. Be it a short one to the shops or a cross-state roadtrip, every drive will be one you’ll enjoy.
