Toyota uncovers new range of fuel efficient engines

Japanese car major Toyota has revealed its new range of engines with primary focus on fuel efficiency. These engines will be at least 10 per cent more efficient than the current crop of engines.

Among the new motors is a 1.3-litre petrol using the Atkinson cycle, usually associated with hybrid engines. Toyota says, "Use of the Atkinson cycle provides an increased expansion ratio and reduces waste heat through a high compression ratio (13.5), resulting in superior thermal efficiency." The new engine also gets a unique intake port and the engines will be 15 per cent more easy on the fuel than current motors.


A 1.0-litre engine jointly developed with Daihatsu was also unveiled. This new engine using the unique intake port does away with the Atkinson cycle and gets a cooled EGR system and a high compression ratio. This bundles with the start/ stop technology and more fuel efficiency aids make this engine about 30 per cent more efficient than the existing engine, says Toyota.

The world’s largest car maker announced that its upcoming models will be equipped with these engines and the company may introduce 14 new engine variants by 2015. These small capacity engines will find their way into Toyota’s small cars and is a step in the right direction by the car maker. In the future cars with higher efficiency will hold the key to success in emerging markets.
