THE CAMPRO ENGINE 官方解说

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.
