Q
what is tdc engine

A TDC engine refers to a point in the cycle of an engine known as “Top Dead Center.” This term is used in both petrol and diesel engines and marks the highest point that the piston reaches in its cylinder. This point is crucial in the timing and operation of an engine, as it signifies either the beginning of a compression stroke in a four-stroke engine or the end of a compression stroke in a two-stroke engine. Proper alignment of an engine’s timing with TDC is essential for optimal performance, as it affects the ignition timing and fuel injection. Misalignment can lead to reduced efficiency and power, and in severe cases, engine damage. Understanding TDC is fundamental for mechanics and engineers in diagnosing and tuning engines for better performance and reliability.

Q
which type of rocket engine is used to maneuver

To maneuver spacecraft, particularly in orbit or deep space, thrusters known as Reaction Control Systems (RCS) are predominantly employed. These engines are relatively small and are designed for precision rather than maximum thrust. They often use hypergolic propellants, which ignite on contact, ensuring immediate and reliable operation. Ion thrusters, another type, provide highly efficient but low-thrust force, ideal for fine-tuning satellite orbits or interplanetary trajectories over extended periods. RCS engines enable spacecraft to adjust orientation, change orbits, and perform docking maneuvers with other spacecraft. The choice between hypergolic and ion thrusters depends on the specific requirements of the mission, considering factors like the need for rapid response versus efficiency over long durations.
