It is currently the first and last inline 4-cylinder engine for Daihatsu’s kei car, which debuted on Mira (L 500 type) which was model-changed in September 1994 . Basic specifications are water-cooled in-line 4-cylinder DOHC 16 valve EFI , inner diameter 61.0 mm × stroke 56.4 mm, total displacement 659 cc.
The J series engine is a short stroke engine capable of revving to a redline of 8500-9000rpm, the J series engine offers smooth accelaration and excellent performance from such a small displacement(cc). In Japan the J series is said to be “engine specialized in sports driving rather than so-called “town ride” that repeats starting and stopping.”
The J Series was typically fitted to kei cars and rated to 47kw (due to kei car laws) however there was a varient of the JB-JL named the JC-DET which has the same bore as the JB 61mm but was stroked to 61mm so 61x61mm = 713cc, this was fitted to the Japanese version of the Sirion, The Storia x4.
There is several different version of the JB-DET engine, variants include top mount or front mounted inter-cooler and the Daihastu Copen version featured a twin scroll turbo. As of August 31, 2012, JB type engine also ended production with the end of the production of the first Copen. Daihatsu will be changing kei cars back to a 3 cylinder design with the 4 cylinder models appearing to be discontinued.
