CAMPRO ENGINE

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.

It 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 with long service intervals.

CAMPRO CPS ENGINE TECHNOLOGY (CPS & VIM)

The CamPro engine utilises 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 provide the best of 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 is drawn through the Long Runner manifold. The resulting slower air flow allows for 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 Integrated Air Fuel Module (IAFM) technology. It helps the engine "breathe" better to 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, be assured that every drive will be one you'll enjoy.
