2 Introduction Modern engines have become more powerful and more efficient. ー How is this possible?

3 1. Intercooler Cooler air means greater the expansion. The greater the expansion, the greater the power.

4 2. Turbochargers The more fuel, the more powerful the engine.

5 3. More intake valves The more intake valves, the more efficient the engine.

6 4. More exhaust valves The more exhaust valves, the more efficient the engine.

7 5. Higher compression The higher the compression, the greater the power.

8 Conclusion We will continue to fine-tune the old and reliable engine design.
