Types of 63.3cc engines
A 63.3cc engine refers to a small-sized gasoline engine that has a total cylinder displacement of 63.3 cubic centimeters. It is a common engine size for handheld power equipment, such as string trimmers, blowers, and hedge cutters. The 63.3cc engine generates more power, which makes it suitable for commercial or professional-grade applications where higher performance is needed. Like any other engine, the 63.3cc engine has different types. They include:
- Two-stroke engines: The 63.3cc 2-stroke engines are popular because they are lightweight and portable. They also have a simple design with fewer moving parts, which reduces the chances of mechanical failure. These engines also generate higher power for their size, making them suitable for applications that require high power output. The 63.3cc 2-stroke engines use a simple fuel system with carburetors, which makes them easy to start and operate. However, it is important to note that the engines have higher emissions and noise levels compared to the 4-stroke engines.
- Four-stroke engines: The 63.3cc 4-stroke engines are more complex and heavier than the 2-stroke engines. The former uses a more complex ignition system, which makes them harder to start. Compared to the 2-stroke engines, the 63.3cc 4-stroke engines have better fuel efficiency and lower emissions. The power output of the 4-stroke engines is relatively consistent compared to the 2-stroke engines.
- Rotary engines: The 63.3cc rotary engine, also known as a Wankel engine, is an alternative to the piston engine. The rotary engine uses a triangular rotor that revolves around a central apex. The rotary engines are known for their smooth operation and high-speed capabilities. The engines have a lightweight and compact design, making them suitable for applications that require high power-to-weight ratios.
- Variable displacement engines: The 63.3cc variable displacement engines adjust the displacement capacity to match the power requirements of different applications. The variable displacement engine can generate high torque and power output, making it suitable for various applications.
- Electric engines: The 63.3cc electric engine requires less maintenance and produces no emissions. Due to the high torque and power output, the electric engines are suitable for demanding applications. However, the 63.3cc electric engines are gradually becoming less common due to the advancements in battery technology, which allows modern batteries to be lighter and provide more power.
