Allows for different drive wheel speeds. Development Goals & Trends

These engines compress only air (or air combined with exhaust gases) during the intake stroke to achieve high efficiency and compression.

Consistent, high-quality lubrication is critical, often called the "blood" of the vehicle, to reduce friction, prevent overheating, and protect components from wear. Key Transmission Components

Modern transmission development focuses on balancing a variety of conflicting goals to optimize performance and efficiency:

This informative overview covers core principles, components, and design goals for engines and transmissions based on engineering fundamentals and industry standards.
