Development of a 1.3L 2-Plug Engine for the 2002 Model ‘Fit’

Article of Honda R&D Technical Review Vol.13 No.2


A lightweight and compact, 1.3L 4-cylinder engine was developed as the new-generation i-Series power train. This engine has twin plugs for each cylinder, and achieves rapid combustion by means of high-precision dual-point sequential ignition control that responds to the engine’s operating conditions. In addition, reducing friction and using the newly developed CVT have yielded the low fuel consumption of 23 km/L in the Japanese 10-15 mode. The engine has achieved ‘J-LEV’ certification by reducing exhaust emissions to 50% of the fiscal year 2000 emissions standards.
