Mercedes's petrol engine + diesel technology

[MeraBoy]

Mercedes-Benz is preparing to display several new frugal drivetrain concepts at September’s Frankfurt Motor Show, the latest being a new ‘DiesOtto’ engine that will be revealed for the first time later this month. The new engine features engine concepts that characterize both diesel and petrol motors, and promises to be as clean as petrol engines but as efficient as diesels.

The technology is similar to Volkswagen’s recently announced Gasoline Compression Ignition system, which works by using spark plugs during start-up and hard acceleration, while relying on sparkless compression ignition, like a diesel, during low load situations.

In an interview with Automotive News, a Mercedes official explained that VW’s technology is still several years away because it requires a special synthetic fuel that’s still in development, while the Mercedes will run on regular petrol.

Interesting information Meraboy , Can't believe that they have created a dual technology engine.=)

Mercedes’ DiesOtto engine does 39MPG in a S-class

Hopefully we all can benefited from it. here's even more good news.

Mercedes is attempting to beat rival Volkswagen to the market with the world’s first mass produced petrol engine that combines the torque and fuel economy of modern diesels with cleaner emissions. Efficient features that have been added to the engine include direct injection, turbocharging and variable compression. Unlike the VW design, the Mercedes engine doesn’t require special synthetic fuels and runs on regular petrol.

The initial concept engine is a small 1.8L four-cylinder, which delivers an amazing 238hp (175kW) and 400Nm of torque. Initial tests have seen fuel consumption at around 39mpg (6L/100km), and this was in a large S-class saloon. The engine works by using sparkless ignition, like a diesel, during low load conditions, and switches back to using a spark plug on cold starts and under full load.

Engineers have another trick up their sleeves. Fuel economy will improve even further with the addition of new hybrid technology, including an integrated starter-generator attached to the flywheel.
