2.0-L DOHC engines on the 2.0X and 2.0XS
Fuel economy has been improved with the redesigned DOHC cylinder head, as well as through optimization of the compression ratio and reduction of the volume of the combustion chamber.
Low-end and mid-range torque is improved, while better fuel economy and lower gas emissions are achieved, primarily through design changes in the engine that generate a stronger tumble gas flow and raise gas intake efficiency.
The use of AVCS contributes to higher power output, while fuel economy is also achieved by improving combustion efficiency through the optimized timing of valve openings and closings.
A design change in the cooling water channel around the spark plug further prevents engine knocking and also helps improve low-end and mid-range torque output.
With the optimization of the diameter and length of the intake manifold, and the adoption of the equal length/constant pulsation independent exhaust system, the engine's intake and exhaust performance has been elevated.
Two catalytic convertors have been placed in tandem. The layout enables the convertors to quickly heat up, which facilitates catalytic activation during engine startup and improves on emission reduction efficiency.
The twin mufflers expand the muffler capacity, bringing noise levels down even lower and reducing exhaust back pressure.
