After revolutionising hybrid technology Toyota Motor Corp is all set to introduce all new range of fuel-efficient gasoline engines. The company claims that this engine is capable of boosting the fuel economy by 10-30 percent.
Toyota Motor Corp has unveiled two new power plant which includes 1.3-L and 1.0-L gasoline engine, surprisingly none of these motors are turbocharged. The first new engine is 1.0 litre developed in collaboration with Daihatsu.
The second new engine is 1.3 litre, this is the first time Toyota will put an Atkinson cycle combustion in pure gasoline motor. The Atkinson cycle improves fuel efficiency keeping the intake valves open briefly during the compression stroke. Toyota has used Atkinson engines in various hybrid models.
Toyota says it combines a high compression ratio and a “tumble flow-generating intake port” to achieve a maximum thermal efficiency of 37 percent but the downside is reduced power. New engines are also coupled with stop-start function for making it more fuel-efficient.
The new engines will be used in models scheduled for partial redesign in the near future, and a total of 14 engine variations will be introduced globally by 2015. The similar tumble flow-generating intake port is for 1.0 litre motor as well.
Honda, General Motors and Ford have introduced 1.0 liter turbocharged motors as there are less chances of Toyota getting into turbocharged motors as the company has invested heavily in hybrid drivetrains. Though Hybrid technology soon will be used commonly we believe Toyota’s 1.0 liter motor is ready to give head to head fight to these rivals.
