Honda develops new 1.8-litre i-VTEC engine
Toronto, Ontario – Honda Canada has announced that it will introduce a new 1.8-litre i-VTEC engine this fall in the new 2006 Honda Civic coupe and sedan models. The new engine will achieve more powerful performance and enhanced fuel economy.
The new engine uses an “intelligent” i-VTEC system that switches the valve timing for maximum efficiency during start-up and acceleration to achieve powerful performance and torque output, and then delays intake valve closure timing during cruising and other low-load conditions for enhanced fuel economy. The company reports that the engine has the off-the-line acceleration performance at low rpm equivalent to a 2.0-litre engine, with fuel economy up to six per cent better than the current 1.7-litre Civic engine.
Other innovations include a variable-length intake manifold for improved torque delivery, and piston oil jets to reduce piston operating temperatures. Overall, the new engine delivers a maximum output of 140 horsepower and 128 lb-ft of torque. It is also shorter, lighter and quieter than the current 1.7-litre engine.
