The Intake Air Fuel Module for the Proton Campro engine is now ready, and is only awaiting Proton’s green light to begin production. This new IAFM is a basically a variable geometry intake system, developed under a joint fast track programme which began in April 2005 by EPMB, Bosch and Proton.

We first heard of it back in October 2006 where it was still in advanced tooling stages, and ever since then everyone has been eagerly awaiting for the first Campros to roll out with the new air fuel module. The IAFM varies intake manifold length to suit different engine conditions – a short runner length for high revs and a long and narrower runner length for low revs.

If designed properly, this can enhance an engine’s torque curve and also help improve the combustion process, making the engine more fuel efficient. This is much-needed with the current Campro engine, which has rather relatively low torque at low to medium engine speeds. The IAFM can be fitted to both Campro 1.3 litre and 1.6 litre engines. The new intake manifold is made of reinforced high thermal plastic which is lighter than the current Campro’s aluminium intake manifold.

“Variable air intake is nothing new to current engine technology. It is present in many engines from other carmakers. We are just happy to be able to bring similar advancement to the Proton Campro engine. This is a team effort with our EPMB staff, Proton engineers, Bosch from Stuttgart and Melbourne and our Korean toolmakers,” said EPMB director of research and development, Zulkefli Baharuddin.

On a side note, the Langkawi International Maritime and Aerospace (LIMA) exhibition to be held this December from the 4th to 8th will feature a locally manufactured hovercraft powered by a Proton engine.
