Volkswagen currently has a few futuristic engine projects running concurrently – one is a diesel engine that uses some petrol engine properties and another is a petrol engine that uses some diesel engine properties.
It calls its experimental diesel engine a “Combined Combustion System”. It’s a diesel engine that can run on synthetic fuels, uses air-fuel mixing style of a gasoline engine, 70% exhaust gas recirculation to reduce NOx emissions, low CO2 output and virtually no soot. This will be road ready within the next 10 years.
The petrol-powered engine uses a special compression ignition system at low engine speeds to help improve fuel economy and emissions. It ignites the air-fuel mixture through high compression using the piston alone, without any spark.
Fuel economy could improve by 17% using this method compared to a conventional spark-ignition system, but at medium to high engine speeds conventional spark ignition is used. This is similar to Honda’s Activated Radical Combustion technology, which also works at relatively lower engine speeds of below 4,000rpm.
Volkswagen is also working on a hybrid engine as well as a fuel cell engine, but it’s executive director for group research Jürgen Leohold did not comment on that matter, instead preferring to focus on the new enhancements to both petrol and diesel technology. “Diesel and petrol engines have had long evolutions, but there is more to be gained,” he said.

huh.. is it really work?
since diesel and gasoline engine is totally different..
diesel engine having a complete combustion with 2 stroke and gasoline in 4 stroke.. if combine the pros each other, then become what??? (^Q^)
in the future, sure one study on internal combustion engine, they are more and more additional theory have to cover.. hehehe….
alot of engine
I wonder whethe any of our policy makers are following this kind of news. We tell the whole world that we want to be a major producer of automobiles, and yet our policies are so outdated. Take the case of diesel fuel. We, the motorists, are supposed to jump for joy when they announced the upgrading of our diesel to euro 2. Other countries including Thailand and Singapore are way ahead of us, and our officials are still cocooned in their offices, having no clue as to what's going in the real world.
If volkswagen have purchase Proton, the latter's car should have been fitted with these engines, not the 'pain in the stomach' campros
I forgot to add just now, cool engines.
if we dont wanna buy a campro powered car, we can always buy a real VW can't we?
the campro may be an engine thats lethargic at low revs, but it still is an engine thats rated up to current European emissions which is euro4 i believe.
if the argument here is about the environment, then i cant see any real fault with the campro, but if power is the argument, then yes, it definitely has issues.
An interesting article from paul was published in NST today talking about campro. if what he said is true about proton's CPS, it might just be able to solve all the current issues it has today.
Well proton only solve the engine problem.. But they mainly for todays market but not for future.. Look at Toyota, VW, Honda even hyundai already have future hybrid engines coming faster then EVE who i think only a prototype until 2010.. What P1 now needs is someone who have better technology for the future, that why VW coming in.. What P1 main problem is their QC problem, design too much local, which are hard to penetrate other market and their persistence on coming out better n worth buying new car models.. Anywayz i like this VW engine, if they manage to built an engine like volvo which can burn diesel, petrol n hydrogen at a same time.. Well next year this engine gonna win the award again!
