Daihatsu displayed a cut-through model of its upcoming 2 cylinder turbocharged direct injection engine enclosed in a glass case at the 2011 Indonesian International Motor Show, which is the “second stage” in its green technology road map.
The first stage is its eco-idle technology, which includes an i-EGR system to reduce emissions and enhance combustion, and a eco-IDLE system which turns the engine on and of automatically to help save fuel during heavy traffic conditions.
According to Daihatsu, the first stage has already been implemented in existing cars like the latest generation Daihatsu Move, and the car that it is expected to launch in September 2011 will also have it. The third stage involves replacing the combustion engine with a fuel cell, which is quite suitable for the kind of city cars Daihatsu makes.
Daihatsu does not reveal much about the two cylinder turbocharged direct injection engine except that it will have a low displacement and will be 30% more fuel efficient than existing Daihatsu engines.
But clues to the specs of this engine can be found in something Perodua managing director Datuk Aminar Rashid last year at the KLIMS 2010. He revealed the target specs for the engine to be 660cc in displacement – 330cc per cylinder, producing 63 horsepower at 4,500rpm and 100Nm of torque from 1,500rpm up to 4,000rpm.
These small 660cc turbocharged engines are really not unusual at all to Daihatsu or pretty much anyone else who participates in the JDM K-Car market. Daihatsu currently has a 658cc engine making 64 PS at 6,400rpm and 92Nm at 4,000rpm. Even Honda who has not toyed with turbocharged engines much in its world cars has a 660cc i-DSI turbo with 64hp and 93Nm in Japan.
But there’s quite a difference between the existing 660cc turbo engines in Japan and this upcoming Daihatsu engine. For one, the JDM engines are all 3 cylinder engines, while this new engine is a 2 cylinder. And if Datuk Aminar Rashid’s quoted specs come true, the planned 2 cylinder will also makes its peak power and torque at much earlier RPMs – 4,500rpm and 1,500rpm compared to the existing breed which only produce its peak power and torque at 6,400rpm and 4,000rpm respectively.
Look after the jump for photos we snapped of the cut-through two cylinder model.
