Technologies That Make Honda's I-VTEC Engine Fuel-Efficient

The all-new Honda City is a beautifully designed car with technical precision and host of innovative technologies. The car has stood tough in competition with the leading sedans in the Indian car market including the Maruti Suzuki SX4.

The winning characteristics of the new Honda City include the advanced i-VTEC engine, the brilliant styling, and a pack of high-end safety features. The intelligent VTEC engine was designed by a team of skilled and talented engineers to meet the growing demand of high fuel-efficiency. In response to the demand, these engineers fine-tuned each and every component of the car engine so that it can generate maximum power and unmatched mileage. With the excellent host of technologies, the VTEC engine boasts about its excellence in all arenas of car industry.

The key reason why the new Honda City has revolution the car market is the powerful and highly efficient i-VTEC engine. Every engine component is tuned to achieve class-leading fuel-efficiency.

Here are some of the technologies that made Honda's i-VTEC engine more fuel-efficient:

Patterned Piston Coating

The best way to improve fuel-efficiency is to reduce friction. This can easily be done by modifying the engine components. Honda engineers did so by changing the surface configuration of the piston coating. A patterned piston coating helped reduce friction which further helps improve fuel-efficiency.

Auto-Tensioner with Drive-Belt

Auto tensioners automatically control the closing and opening of the intake and exhaust valves of the engine. When fitted with the drive belt, it helps in monitoring the tension of the timing belts with respect to the changing speed. Honda engineers fitted the auto-tensioner with the auxiliary drive belt connecting the crankshaft and the camshaft. The tensioner in connection with the drive-belt absorbs all variations in the tension and eventually helps improve fuel-efficiency.

Plastic Covering

Fuel-efficiency can also be improved by reducing the overall weight of the car. If the car weight is more, the engine will need more power to pull the car and if the weight is reduced, comparatively less power is required to pull the car. Honda's engineers also applied the same principle and reduced the weight of the engine. They used plastic covers instead of aluminium covers to cover the car engine. Plastic engine covering helped reduce the weight of the engine by about one kilogram, thereby reducing overall weight of the car and increasing fuel-efficiency.
