Goped engine

Types of Goped Engine

The Goped engine is a small and portable engine found in gopeds. A goped is a small, motorized, or human-powered vehicle with a handlebar and footboard. The Goped engine is further divided into two main types based on the power source. They include the petrol-powered engine and the electric-powered engine.

• Gas-powered Goped engines:

  The gas-powered goped engine uses petrol as its power source. The gas-powered goped engine is further sub-divided into two types; air and reed valve gopeds.

  Air Valve: The air valve goped engine uses gas to power the engine. In this engine, the valves are mechanically linked to the camshaft. When the piston moves down during the intake stroke, it creates a low pressure in the cylinder. The low pressure in the cylinder causes the valves to close slightly. As a result, the air and gas mixture will leak out of the cylinder through the closed valves. This leads to reduced engine efficiency and power. Go-ped with air valve engines are mainly found in older vehicles.

  Reed Valve: The reed valve goped engine also uses gas to power the engine. In this engine, the valves are not mechanically linked to the camshaft. Instead, the valves are placed on a spring-loaded plate. When the piston moves down during the intake stroke, the pressure in the cylinder drops, causing the reed valves to open slightly. This allows a one-way flow of air and gas from the crankcase into the combustion chamber. The opened reed valves close quickly when the piston moves up during the compression and exhaust strokes. This prevents the air and gas from leaking out of the cylinder. As a result, the reed valve goped engine offers better performance and efficiency. The reed valve goped engine is commonly found in modern goped models.

Electric-powered Goped engines:

Gopeds use petrol as their power source. The electric-powered goped engine is also sub-divided into two types; lithium and lead-acid battery gopeds.

• Lithium battery gopeds:

  The lithium battery goped engine is a modern technological advancement in goped engines. The lithium batteries are lightweight and have a high energy density, making them suitable for gopeds. The lithium battery has a long cycle life and can be charged quickly with a high charge current.

• Lead-acid battery gopeds:

  The lead-acid goped battery is the oldest technology used in goped engines. The lead-acid battery-powered gopeds are heavier and have a lower energy density compared to the lithium battery. The lead-acid batteries have a shorter cycle life and take a longer time to charge.

Specification & Maintenance of Goped Engine

Engine-powered Gopeds have become a popular choice for many people. Whether it is a fancy Goped for sale or a budget-friendly option, the Goped engine specs are hard to ignore. So, what are the Goped engine specs?

• Engine Type:

  The engine type is the first Goped engine specification. While some Gopeds have 2-stroke engines, others have 4-stroke engines.

• Displacement:

  The size of the engine is referred to as its displacement. The Goped engine displacement ranges from 23cc to 49cc or more. Riders can expect better performance and power from engines with larger displacements.

• Max Power:

  The Goped engine max power is measured in watts or horsepower. Some engines produce between 1.5hp to 3hp or more. The max power affects the Goped's speed and acceleration.

• Max Torque:

  Torque is the force that drives the Goped forward. The Goped engine max torque ranges from 1.5 to 3nm or more. Like max power, torque also affects speed.

• Fuel Type:

  Gasoline is typically the fuel type used by Gopeds. Some Gopeds also use a 2-stroke oil mixture. The fuel type and ratio affect the Goped engine performance.

• Starting System:

  The starting system of Gopeds can either be electric or recoil. Electric starters are more convenient as they require less physical effort to start the engine. Recoil starters require more physical effort.

• Ignition System:

  The Goped engine ignition system is either CDI or coil-based. The CDI ignition system provides a more reliable spark, while coil-based ignition systems are less reliable.

• Cooling System:

  Some Gopeds have air-cooling systems, while others have water-cooling systems. Water cooling is more effective than air cooling. However, the cooling system affects the Goped's ability to handle heat.

Maintaining the Goped engine is very important. This is because proper maintenance ensures that it runs smoothly, efficiently, and reliably while extending its lifespan. Here are some tips on how to maintain the Goped engine.

• Regular Oil Change: Engine oil lubricates the moving parts of the Goped engine. It also protects it from wear and tear. Over time, the engine oil breaks down and loses its effectiveness. Therefore, it is important to regularly check the engine oil level and change it at the recommended intervals.
• Clean Air Filter: The Goped engine requires a constant supply of clean air for combustion. However, the air filter might become clogged with dirt and dust particles over time. This affects the engine's performance. As such, it is important to regularly inspect the air filter and clean it with a mild detergent.
• Inspect Spark Plug: The Goped spark plugs ignite the fuel-air mixture in the engine's combustion chamber. Like every other part of the engine, the spark plugs require maintenance. This is because they can become worn out, dirty, or damaged. Therefore, it is important to regularly check the spark plugs for signs of wear or damage and replace them when needed.
• Fuel Quality: The quality of fuel that powers the Goped engine is just as important as the engine itself. Using good quality fuel with the right octane rating is important for optimal engine performance.

How to choose GoPed engines

With a variety of Goped engines available in the market, choosing the right one can be a daunting task. Here are some factors to consider:

• Type of engine

  The type of engine should be considered first when choosing a Goped. There are two types of engines to choose from, the gas engine and the electric engine. The gas engine is powerful and suitable for longer rides, while the electric engine is quieter and requires less maintenance.

• Size and weight

  The size and weight of the GoPed should be considered. A larger and heavier GoPed will be more difficult to maneuver, but it will be more stable at higher speeds. A smaller and lighter GoPed will be easier to carry and navigate through traffic, but it will be less stable and a bit slower.

• Terrain

  The type of terrain to be covered should be considered. Some Gopeds are better suited for off-road riding, while others are designed for pavement and city streets. If the area has a variety of terrains, then a convertible Goped is the best choice.

• Budget

  Different Gopeds come with different price tags. Settle for a Goped engine that is affordable and within the budget. Don’t forget to consider the long-term costs like maintenance, fuel, and insurance.
