Toyota says its new gas engines boost fuel efficiency at least 10 percent

Toyota is planning a global introduction of vehicles that feature a series of newly developed, highly efficient gasoline engines that achieve outstanding thermal efficiency* and fuel efficiency improvements of at least 10 percent.

The new engines leverage combustion and loss-reduction technologies that Toyota has refined in its dedicated hybrid engines.

Two engines will form the core of the new series.

The first is a 1.3-liter gasoline engine using the Atkinson cycle normally used in dedicated hybrid vehicles. It achieves a maximum thermal efficiency of 38 percent, which is top-level performance among mass-produced engines. 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. Toyota aims to further improve the fuel efficiency of the engine by utilizing other innovations, including an intake port with a new shape that generates a strong tumble flow (whereby the air-fuel mixture flows in a vertical swirl) inside the cylinder, and a cooled exhaust gas recirculation (EGR) system paired with Variable Valve Timing-intelligent Electric (VVT-iE) technology to improve combustion and reduce loss. The new features, combined with idling stop and other functions, will lead to fuel efficiency gains of approximately 15 percent by comparison with current vehicles.

The second is a 1.0-liter gasoline engine, jointly developed with Daihatsu Motor Co., that has achieved maximum thermal efficiency of 37 percent due to a similar tumble flow-generating intake port, a cooled EGR system, and a high compression ratio. Combining the idling-stop function and various other fuel-consumption reduction technologies allows vehicles to achieve a maximum fuel-efficiency improvement of approximately 30 percent over current vehicles.

Toyota is not letting the cat out of the bag on which model cars will get the new engines, though. "The new engines will be used in models scheduled for partial redesign in the near future," the company says. A total of 14 engine variations will be introduced globally by 2015.
